Overview
Cancer that originates in the breast tissue.
Origin
a mix of environmental and genetic variables.
Genetics: 5–10% of instances are due to genetic factors, but the majority are polygenic risk. 2% of cases contain BRCA-1 (17q) and BRCA-2 (13q) gene mutations, with carriers having a lifetime risk of up to 87%. Li-Fraumeni syndrome (TP53), Cowden's syndrome (PTEN), Peutz-Jeghers syndrome (STK11/LKB1), ataxia-telagiectasia (ATM), and Muir-Torre syndrome (MSH2/MLH1) are examples of rare hereditary breast cancer syndromes.
Risk factors include age, nulliparity, early menarche, late menopause, menopausal hormone replacement medication, obesity, alcohol consumption, and extended exposure to female sex hormones, especially oestrogen.
Epidemiology is the second most common cause of cancer-related deaths in women worldwide, after lung cancer in the United States. In the UK, the lifetime risk is 1 in 9. peak incidence in people aged 40 to 70. Just 1% of all breast cancers in men are rare.
History
perhaps found by screening.
Primary symptoms include breast lumps, which are typically painless, breast form alterations, and nipple discharge.
Axillary lump, bone pain, weight loss, and paraneoplastic disorders (such as cerebellar syndrome) are signs of secondary spread.
Examination
When the patient is supine and upright, the breasts should be examined for asymmetry, peau d'orange (oedema), dimpling or tethering, nipple scaling or inversion, or, in more severe situations, ulceration.
Use a clockwise radial approach for palpating hard, irregular, or fixed lumps.
Check for hepatomegaly, chest anomalies, palpable axillary lymph nodes, supraclavicular lymph nodes, and bone discomfort.
Investigations
Triple assessment: A standardized procedure that includes a clinical evaluation, imaging (MRI, CT, or mammography), and tissue diagnosis (cytology or biopsy) to investigate a breast lump.
Mammography (Fig. 1): A valuable screening tool for women over 35. In the UK, screening doesn't start until beyond age 50. The craniocaudal and mediolateral oblique views are typical. Spiculated lesions and branching or linear microcalcifications are characteristics of malignancy.
Ultrasound: To distinguish between dangerous solid lesions and benign cystic lesions. More beneficial for women under 35.
Fine-needle aspiration: Less invasive, enables cyst drainage and cytology of individual breast masses.
Core biopsy: Allows for histological diagnosis; can be image guided.
Sentinel lymph node biopsy: After injecting radioactive tracer or blue dye in the vicinity of the breast lesion, a nuclear scan locates the sentinel node, which is then biopsied to look for spread.
CT (chest, abdomen, pelvis), PET, or bone scans for metastases are the staging options.
Blood: CA-15-3 tumor marker, bone profile, LFT, FBC, U&Es, and Ca2₠.
Histopathology:
In situ cancer:non-invasive ductal or lobular carcinoma in situ (DCIS, LCIS) that preserves the basement membrane.
Invasive: Ductal carcinoma accounts for 75% of all breast cancer cases.
Other: tubular, mucinous, medullary, cruriform, papillary, lobular (10–15%, Indian filing arrangement of cells), and Paget's disease of the nipple (ductal carcinoma in situ infiltrating the nipple).
Phlloides: Fibroepithelial tumours that can be benign or malignant.
Molecular prognostic factors: Oestrogen and progesterone receptors (ER, PR) and HER-2
expression (20–30% of cancers) are valuable prognostic indicators and guide treatment.
Flow cytometry measures DNA content (ploidy) and S-phase fraction (cell proliferation
rate).
Grading: The Nottingham modification of the Bloom and Richardson grading system is a
prognostic indicator. Three features assessed are tubule formation, nuclear size/
pleomorphism and number of mitoses. Scores are used to generate Grades 1 (well
differentiated) to 3 (poorly differentiated).
Staging: The UICC TNM-staging system.
Tumour size (T): T1: <2 cm; T2: 2–5 cm; T3: >5 cm; T4: any size with chest wall or skin
extension.
Nodes (N): N1: mobile ipsilateral axillary; N2: fixed ipsilateral axillary; N3: ipsilateral internal
mammary nodes.
Metastases (M): M0: no distant metastases; M1: distant metastases.
Supervisory
Breast care nurses, radiologists, oncologists, and breast surgeons are all part of the multidisciplinary management team. The size, location, type, stage, and consideration of each patient's unique wishes all play a role in the decision to remove the cancer surgically.
Breast-conserving surgery: Segmental mastectomy or wide local excision (if the patient is willing to receive radiation therapy and the single cancer is less than 5 cm). Radiological wire localization can be required for smaller lesions.
Modified radical mastectomy: dissection of the axillary lymph nodes and total mastectomy.
Axillary surgery is required for node staging and can vary from level III clearance (lymph nodes up to and above the pectoralis minor muscle) to sentinel node biopsy, which removes three nodes on average.
Breast reconstruction: Usually done after the surgery, but sometimes it happens right away after surgical excision. Techniques include transverse rectus abdominis myocutaneous flaps, latissimus dorsi flaps, and breast prosthesis.
Radiotherapy: After breast-conserving surgery, external beam radiation is sometimes used as neoadjuvant therapy and to palliate advanced tumors.
Chemotherapy: Adjuvant, palliative, and neoadjuvant settings are possible for treatment. Visceral involvement, oestrogen receptor-negative tumors, fast-progressing illness, or failure of hormonal therapy are more common in premenopausal women.
Combination therapy regimens, such as those involving cyclophosphamide, methotrexate, and 5-fluorouracil (CMF), are customized for each patient.
The primary first-line treatment for oestrogen receptor-positive tumors is hormonal therapy, which includes selective oestrogen receptor modulators like tamoxifen. Additional options include ovarian ablation using LHRH analogs, such as goserelin, aromatase inhibitors in postmenopausal women, such as letrozole or anastrozole, and selective oestrogen receptor downregulators, such as progestins and fullvestrant.
Biological therapy: In nodal and HER-2-positive cancer, trastuzumab (Herceptin), a monoclonal antibody that targets the HER-2 receptor (a cell growth promoter), is used in conjunction with chemotherapy and has been demonstrated to increase overall and disease-free survival.
Complications
significant physical or psychological damage following surgery or diagnosis.
Hypercalcemia, spinal cord compression, bone pain, and problems with the abdomen, lungs, or brain can all result from metastases.
Venous thrombosis and endometrial cancer are caused by tamoxifen. Osteoporosis, joint/muscle pain, aromatase inhibitors. The cardiotoxicity of herceptin.
Following surgery, there may be a local recurrence, wound infection, hemorrhage, lymphoedema, shoulder pain, sensory loss (the intercostobrachial nerve is frequently sacrificed, resulting in numbness in the inner, upper arm).
Fatigue, skin alterations, and lymphoedema are side effects of radiation therapy.
Prognosis varies according on stage, grade, and kind. Total 5-year survival is 100% if the illness is limited to the breast, 50%–90% if it is node-positive, and 20% if it has spread to distant organs.tumors of the fibroepithelium that may be benign or cancerous.
& HER-2 expression (20–30% of malignancies) and oestrogen and progesterone receptors (ER, PR) are important prognostic markers that help determine treatment.
DNA content (ploidy) and S-phase fraction (cell proliferation rate) are measured by flow cytometry.
Grading: A prognostic indicator is the Nottingham version of the Bloom and Richardson grading system. Nuclear size/pleomorphism, quantity of mitoses, and tubule development are the three characteristics that are evaluated. Grades 1 (highly differentiated) through 3 (poorly differentiated) are created using scores.
UICC TNM-staging system is used for staging.
Tumor size (T): <2 cm for T1, 2–5 cm for T2, >5 cm for T3, and any size with skin or chest wall expansion for T4.
Nodes (N): ipsilateral internal mammary nodes (N3), mobile ipsilateral axillary nodes (N1), and stationary ipsilateral axillary nodes (N2).
Metastases (M): M0 denotes no distant metastases, while M1 denotes distant metastases.

Surgery - Benign Breast Disease
Definition
breast diseases that are not cancerous, such as physiopathological abnormalities of the adipose, stromal, epithelial, or vascular components of the breast.
Fibroadenoma: Occurs when a breast lobule hyperplasia occurs and comprises both normal connective tissue and epithelial cells.
Fat necrosis: Amorphous material, inflammatory cells, including foreign body giant cells, and irregular and necrotic adipocytes can all resemble cancer.
A normal involution is aberrated in sclerosing adenosis.
Duct ectasia: This condition is brought about by central ducts becoming dilated with secretions; if leaking into periductal tissue happens, it can result in periductal mastitis, an inflammatory response.
Origin
Under endocrine regulation, breast tissue changes in a variety of ways. Trauma is the secondary cause of fat necrosis. Benign conditions are mapped using the ANDI (aberrations of normal development and involution) classification system based on the degree of abnormality as well as the pathophysiology.
Risk Factors
possibly less common in people using birth control pills. One risk factor for periductal masttitis is smoking.
The study of epidemiology
Only 10–20% of instances are thought to proceed to a histopathological diagnosis. As many as 60% of women have diffuse fibrocystic alterations, and 70% of them have mastalgia.
Breast cysts are more prevalent in people 40 to 50 years old, and fibroadenomas are more common in people 15 to 25 years old. Unless a woman is on hormone replacement therapy (HRT), these conditions often go away after menopause.
History
Past history of lump or enlargement, breast pain or discomfort (cyclical or non-cyclical mastalgia).
Breast discharge: cancer should be suspected if it is bloodstained. It is important to determine risk factors for breast cancer, such as menstruation history, family history, pregnancy history, usage of OCP, and hormone replacement treatment.
Examination
Breast nodules, focal or widespread.
Typically, fibroadenomas are smooth, well-circumscribed, and movable lumps that have a diameter of 1-2 cm in breast mice.
Nipple discharge that is yellow or green (duct ectasia).
There are no signs of malignancy, such as dimpling, peau d'orange skin changes, or swollen lymph nodes in the arms.
Investigational studies
Typically carried out in conjunction with triple assessment:
1. A clinical assessment.
2. Imaging: USS in younger patients (<35 years old) or mammography (craniocaudal and oblique mediolateral views, spot compression and magnification views). Less frequently, benign lumps will become calcified (microcalcifications strongly signal malignancy). MRI examinations are also beneficial.
3. Cytology/Histology: By trucut or excision biopsy, or by FNA (fine-needle aspiration) cytology.
Conservative management includes treating the symptoms, such as analgesia and mastalgia with evening primrose oil, which is a rich source of gammalinoleic acid. Tips for eating a lower-fat diet and using supportive bras.Danazol is applied as a backup therapy. 17-a-ethinyl testosterone inhibits the production of ovarian steroids, reduces gonadotropin release, and stops the LH surge.
If fibroadenomas are significant or the patient requests it, they can be removed or treated cautiously.
Simple cysts should totally vanish after aspiration and don't require aspiration unless clinically required. In the absence of that, treat it like a breast lump.
Surgery: This involves removing or excising the breast lump through biopsy; if there is any reason to suspect that the lump is not benign, a broad local excision should be carried out. The treatment for intraductal papillomas is microdochectomy. In duct ectasia, the Hadfields (or Adairs) procedure excises the central ducts.
Complications
Pain reappearance.
The prognosis is good, although recurrence is frequent. Fibroadenomas: women with simple FA do not have an elevated risk of cancer, nor is there a higher family history of breast cancer.

Surgery - Lung Cancer
Introduction
lung primary malignant tumor. The WHO classifies bronchocarcinoma as: Adenocarcinoma, large-cell carcinoma, squamous cell carcinoma, and adenosquamous carcinoma are classified as small cell (20%) and non-small cell (80%).
Etiology
Lung tumors in their primary form: It is believed that factors including asbestos exposure and smoking, whether active or passive, eventually produce in genetic alterations that promote neoplastic transformation.
Tumors typically originate in the main or lobar bronchi (refer to Fig. 2), whereas adenocarcinomas typically manifest in distant locations.
supplementary tumors One common location for metastases is the lung.
Risk Factors
Cigarette smoking, air pollution, occupational exposures (polycyclic hydrocarbons, asbestos, nickel, chromium, cadmium, radon).
Epidemiology
The most prevalent deadly cancer in the West (18% of all cancer fatalities globally), accounting for 35,000 annual deaths in the UK, and three times more common in men than in women.
H HISTORY
5% of cases may show no symptoms despite radiological abnormalities.
Primary cause: Chest discomfort, cough, hemoptysis, and recurrent pneumonia.
Owing to local invasion: For instance, palpitations (arrhythmias), hoarseness and a cow cough caused by the left recurrent laryngeal nerve, dysphagia in the oesophagus, and brachial plexus (Pancoast's tumor).
Weight loss, exhaustion, bone pain or fractures, fits—all may be signs of metastatic disease or paraneoplastic events.
History and Examination
It's possible that none exist.
monophonic wheeze that is fixed.
indications of a pleural effusion or lobar collapse.
symptoms of metastases, such as hepatomegaly or supraclavicular lymphadenopathy.
Horner syndrome.
Investigations
Diagnosis options include sputum cytology, CT or ultrasound-guided percutaneous biopsy, lymph node biopsy, bronchoscopy with brushings or biopsy, and CXR.
TNM staging: Using CT or MRI scans of the head, abdomen, and chest, as well as bone and PET scans, is based on tumor size, nodal involvement, and metastatic metastasis. It is possible to employ invasive techniques like video-assisted thoracoscopy or mediastinoscopy.
Blood: FBC, U&Es, Ca2+ ("bone metastases"), AlkPhos, and LFT. Hypercalcemia is a prevalent condition.
Pre-operative care includes an assessment of general anesthesia, V/Q scan, ECG, and echocardiography, as well as pulmonary function testing (FEV1 >80% anticipated to tolerate a pneumonectomy; lung resection is contraindicated if FEV1 <30% predicted).
Management
Multidisciplinary conversation about the best course of treatment and tumor staging. Resectibility of the tumor (stage I and II disease, specifically IIIa) and operability (if a patient is fit enough to undertake surgery) are important factors to take into account (surgery is not recommended for small-cell cancer). It is essential to have an open dialogue with the patient regarding the risks, advantages, and prognosis. Surgery is only considered in 14% of instances.
Surgery.
Anesthesia: The lung to be operated on is isolated from the ventilatory circuit using a double-lumen endotracheal tube. The lung that will be operated on has a central line inserted ipsilaterally.
The location of the urine catheter and arterial line. To provide effective regional analgesia, a thoracic epidural catheter is frequently inserted. Method: When a bronchial tumor is detected, a rigid bronchoscopy is conducted after anesthesia is administered. Prophylactic antibiotic usage is made. With the patient in a lateral decubitus position, a posterolateral thoracotomy is typically performed with gradual rib distraction. The lung is moved, the tumor's location is determined, and the lymph nodes are examined. The pulmonary artery, vein, and bronchial tree branches are located, and if necessary, a lobectomy is carried out (60 percent of resections). Both the upper and lower lobes of the right lung can be preserved during a bilobectomy. Pneumonectomy, which entails partial resection and rebuilding of the bronchi, is avoided with sleeve resection. Pneumonectomy: one lung is removed in 25 percent of resections.
Air is drained via the front apical drain, while blood or fluid is drained via the posterior basal drain.
Unoperable: Multimodality treatment that combines chemotherapy and radiation therapy increases survival.
Docetaxel is frequently utilized. Erlotinib, an inhibitor of the epidermal growth factor receptor (EGFR), is a biological therapy used as a second-line chemotherapy drug.
Palliative and end-of-life care: includes endobronchial stents, laser treatment for bronchial tumors, problem management, and pain relief.
Complications
Metastases (usually liver, bone, and brain), pleural effusion, pulmonary hemorrhage, lobar or lung collapse, local invasion (e.g., brachial plexus, sympathetic chain, recurrent laryngeal nerve, SVC), and paraneoplastic syndromes (especially common in small-cell carcinomas, e.g., SIADH or ectopic ACTH production; squamous cell carcinomas are associated with hypercalcaemia of malignancy).
Surgery: lesion not surgically resectable (should be less than 5%).
Lobectomy: Reoperations are occasionally necessary due to frequent air leakage.
Pneumonectomy carries a high risk of cardiac arrhythmias, failure or MI, pneumonia and atelectasis, pulmonary oedema, bronchopleural fistula, hemorrhage, and pulmonary embolus. It also carries a significant physiological strain.
Prognosis
Depending on the situation, but not very good. When small-cell carcinoma first manifests, it frequently has spread. 5-year survival rate overall is less than 5%. 25% of patients survive five years after resection for early-stage illness. Pneumonectomy mortality is 8%, but lobectomy mortality is less than 2%.

Docetaxel is frequently utilized. Erlotinib, an inhibitor of the epidermal growth factor receptor (EGFR), is a biological therapy used as a second-line chemotherapy drug.
Palliative and end-of-life care: includes endobronchial stents, laser treatment for bronchial tumors, problem management, and pain relief.
Complications
Metastases (usually liver, bone, and brain), pleural effusion, pulmonary hemorrhage, lobar or lung collapse, local invasion (e.g., brachial plexus, sympathetic chain, recurrent laryngeal nerve, SVC), and paraneoplastic syndromes (especially common in small-cell carcinomas, e.g., SIADH or ectopic ACTH production; squamous cell carcinomas are associated with hypercalcaemia of malignancy).
Surgery: lesion not surgically resectable (should be less than 5%).
Lobectomy: Reoperations are occasionally necessary due to frequent air leakage.
Pneumonectomy carries a high risk of cardiac arrhythmias, failure or MI, pneumonia and atelectasis, pulmonary oedema, bronchopleural fistula, hemorrhage, and pulmonary embolus. It also carries a significant physiological strain.
Prognosis
Depending on the situation, but not very good. When small-cell carcinoma first manifests, it frequently has spread. 5-year survival rate overall is less than 5%. 25% of patients survive five years after resection for early-stage illness. Pneumonectomy mortality is 8%, but lobectomy mortality is less than 2%.

Surgery - Pulmonary Embolism
Introduction
blockage of the pulmonary arteries, usually caused by a thrombus that entered the system from another location.
Etiology
Thrombus (rarely from the right atrium in patients with atrial fibrillation, and more than 95% originating from DVT of the lower limbs). A variety of substances, such as amniotic fluid, air, fat, tumors, and mycotic emboli from right-sided endocarditis, can also embolise to pulmonary arteries. Patients undergoing surgery, as well as those with immobility, obesity, OCP, heart failure, or cancer, are among the groups most at risk.
Epidemiology
very common, particularly in hospitalized patients; affect 10–20% of individuals with proximal DVT that has been verified.
History
Depending on the pulmonary embolus's size and location. Minimal: Could show no symptoms. Moderate: Cough, hemoptysis, pleuritic chest discomfort, and sudden onset dyspnea. Large (or proximal): All of the previous symptoms plus abrupt death, shock, collapse, acute right heart failure, or severe central pleuritic chest discomfort. Pulmonary hypertension symptoms include multiple minor recurring episodes.
Examination
Evaluation of clinical probability: Different scores can be used to estimate probability and direct management and additional research. Apply regional regulations.

Examination
Evaluation of clinical probability: Different scores can be used to estimate probability and direct management and additional research. Apply regional regulations.
Investigational studies
Low probability: Use the blood test known as the D-dimer (sensitive but insensitive to cross-linked fibrin breakdown products). High probability: Imaging is necessary. Further preliminary inquiries: Blood: Think of a thrombophilia screen, ABG. ECG: May be normal, however tachycardia, right axis deviation, or RBBB are more frequently seen. Classical patterns such as SI, QIII, or TIII are not very prevalent. CXR: Usually normal, but check for other differential diagnosis. Spiral CT pulmonary angiogram: The preferred initial diagnostic procedure. Very sensitive for medium-to large-sized emboli, but poor sensitivity for tiny emboli. Inhaling krypton-81 gas and administering IV 99mTc macro-aggregated albumin constitute the ventilation-perfusion (VQ) scan. This shows where there may be a mismatch between perfusion and ventilation. Not appropriate because to interpretation difficulties if there is a concurrent lung disease or an abnormal CXR. The gold standard for pulmonary angiography is invasive. seldom required. To check for venous thrombosis, do a lower limb Doppler ultrasound. Right heart strain may be seen on an echocardiogram.
Management
Primary prevention: Heparin prophylaxis in at-risk individuals (e.g., those undergoing surgery) and graduated pressure stockings (TEDs). prompt mobilization and sufficient hydration following surgery. If the patient's blood pressure is stable, they should start on O2, anticoagulate with heparin or LMW heparin, and switch to oral warfarin medication (INR 2-3) for at least three months. drugs that reduce pain. If hemodynamically unstable (massive PE): If cardiac arrest is likely, resuscitate, provide oxygen, IV fluid resuscitation, and thrombolysis with tissue plasminogen activator (tPA) may be considered solely on the basis of clinical considerations. Embolectomy, either surgical or radiological (where thrombolysis is contraindicated). When anticoagulation is contraindicated or for recurrent pulmonary emboli, IVC filters (such as the Greenfield filter) may be placed.
Complications
Right heart failure, pulmonary hypertension, death, and pulmonary infarction.
Prognosis
30% of deaths go untreated, 8% are treated (because of recurring emboli or underlying disease). "Risk of future thrombo-embolic disease" is present in patients.

Surgery - Abscesses
Introduction
An abscess is a mass of necrotic tissue that is encircled by a layer of inflammatory exudate and contains both dead and living neutrophils suspended in tissue breakdown products (pus).
Etiology
An attempt is made to wall off the area in order to prevent the infection from spreading further if a penetrating injury, local infection, or the migration of normal flora to sterile sections of the body break the tissue barrier. Staphylococcus, streptococci, enteric bacteria (like Escherichia coli), various coliforms, and anaerobes (like Bacteroides spp.) are examples of common bacteria. Traditionally, TB leads to "cold" abscesses. Please refer to Associations/Risk Factors and Pathology/Pathogenesis.
Risk Factors
Local: A hernia repair mesh, embedded hair, splinters, tissue necrosis, an underperfused area, or a foreign body that serves as an infection focal point. Systemic: diabetes, immunosuppression (may prevent pus from forming, though).
Epidemiology
prevalent across all age groups.
H HISTORY
The patient may report systemic symptoms like fever and feeling under the weather, or local symptoms like pain, swelling, heat, redness, and decreased function of the area where the abscess is present (dolor, tumor, calor, rubor, and functio laesa, the Celsian signs of acute inflammation).
Examination
At the location of the abscess, the aforementioned signs of acute inflammation are noticeable. The only indication that the condition is present within an organ (such as the liver, lung, or body cavity) could be a swinging pyrexia, which is brought on by the intermittent release of inflammatory mediators or bacteria into the bloodstream and should prompt the search for an infected collection. An old proverb states that pus is under the diaphragm (subphrenic abscess) if pus is both anywhere and nowhere.
Pathogenesis
When pus, a mixture of bacteria and cell debris, forms, it triggers a severe acute inflammatory response. An abscess develops when fibrinous exudate and granulation tissue (fibroblasts and macrophages) encircle it, followed by collagen deposition and walling off. Mycobacterium-containing clusters of caseating necrosis are known as "cold abscesses" because they do not elicit an immediate inflammatory reaction.
Investigational studies
FBC ("neutrophils") in blood.
Imaging: To locate the location of a collection or abscess, imaging techniques such as ultrasound, CT, MRI, or even 67Ga white cell scanning may be employed.
Aspiration: Pus is acidic and low in glucose. Pus culture for the purpose of determining antibiotic sensitivity.
Management
Prevention: If administered early in an infection, preventive antibiotics (e.g., during procedures). Usually ineffective after an abscess develops.
In general: Pus drainage, foreign material and necrotic material removal, antimicrobial cover, and predisposing cause repair are among the guiding principles involved.
Surgery: To remove pus, an incision is made, the cavity is debrided, and then the cavity is allowed to empty freely using either packing (if the cavity is shallow) or drains (if the cavity is deep).
Interventional radiology: An abscess's contents can be located and aspirated using ultrasound or CT guidance.
Complications
Skin cellulitis or bacteremia combined with systemic sepsis may arise from spread. A discharging sinus, fistula, or persistent abscess may develop if the infection's focal point is not removed.
Antibiotics can occasionally permeate and cause an antibioma, or sterile collection, to form. In the event where slow expansion is restricted by strong facial planes, the surrounding tissues may experience pressure necrosis. Tissue that is typically functioning may be destroyed by abscesses (liver or nephric abscess, for example).
Prognosis
Good if predisposing cause is eliminated and sufficiently drained. Abscesses may spontaneously empty themselves and have a tendency to "point" to the closest epithelial surface if left untreated. Deep abscesses could experience dystrophic calcification and turn chronic.

Surgery - Advanced Traumatic Life Support (ATLS)
Indications
Early trauma management that prioritizes addressing the condition that poses the biggest risk to life.
Procedure
Pre-hospital phase: The trauma patient is promptly assessed. Treatment of shock, hypoxemia, and prompt transfer to a suitable hospital.
Hospital phase: A trauma team, which typically consists of a general surgeon, an orthopaedic surgeon, an anesthetist, and nursing support, conducts the primary survey. The team leader leads the team. Every team member should have a predetermined job, and the team leader should oversee a methodical approach to the primary and secondary surveys.
Control of the airways and the c-spine: suction and oral examination for foreign bodies. Assess the patient's (conscious or unconscious) capacity to maintain their own airway. Chin lift/jaw push, suitable cricothyroidotomy or intubation, orally or nasopharyngeally (not in cases of head trauma) as needed.
Breathing: Use a non-rebreather mask to provide 100% oxygen. Examine the respiratory rate, bilateral breath sounds, symmetrical chest expansion, and tracheal deviation. oximetry of the pulse.
In the event of a tension pneumothorax, decompress the needle on the affected side. Look for emphysema under the skin. A chest drain and a dressing with a seal on three sides are necessary for an open sucking pneumothorax. Seek out the flail chest.
Circulation: Measure blood pressure, pulse pressure, capillary return, and pulse in addition to performing intravenous access (using two large-bore peripheral cannulae) and drawing blood for cross-matching FBC, U&E, and G&S.
Assessing the major bodily cavities, the belly, the pelvis for evidence of pelvic fractures, the chest for hemothorax, and the management of external bleeding are all important aspects of treating shock and hemodynamic instability as well as internal bleeding.
Fluid resuscitation (crystallin, collloid, or blood); nonetheless, "permissive hypotension" of systolic blood pressure may be necessary if intracavity bleeding is not yet under control (not in severe head injury where cerebral perfusion pressure should be optimized). If stable, get a CT scan or a FAST (focused abdominal sonogram for trauma).
Disability: Gross neurologic damage assessed using the Glasgow Coma Score (GCS) or an AVPU (Alert, Voice elicits response, Pain elicits response, Unresponsive) score. Verify your blood sugar.
Exposure: Examine the patient for more injuries, undress them entirely to avoid hypothermia, logroll them, and check for spinal or posterior injuries. Treat and prevent hypothermia by using heated IV fluids, blankets, etc.
Regular evaluation is essential. Any decline necessitates a quick reassessment of the ABC.
A large portion of the ABC may be completed in simultaneously when a team is doing the assessment and resuscitation.
Secondary survey: Does not start until after the completion of the primary survey and the start of resuscitation. comprehensive assessment. MANY history (drugs, allergies, past medical conditions, pregnancy, last meal, and incidents connected to the accident). Regular evaluation is essential! comprehensive neurological assessment. Radiology as well as further recommended testing, including as ABG, FAST scan, and radiographic imaging for any fractures. stomach tube or urinary catheter. Injuries determine whether to pursue more decisive management. Sometimes a transfer to a tertiary trauma or neurosurgical center is required.
Investigational studies
Blood: FBC, suitable crossmatch, U&E, LFTs, clotting, and blood grouping.
Urinalysis: b-HCG if pregnancy risk, urine dipstick for haematuria.
Radiographs of the pelvis, chest, and cervical spine are included in the primary survey. An upright chest X-ray can be used to assess a penetrating abdominal injury.
FAST scanning is now the go-to non-invasive quick assessment method for trauma patients' hemoperitoneum.
CT scanning: When the patient is stable, as needed. An urgent laparotomy is required if there is any suspicion of an intra-abdominal bleed (hypotension, enlarged belly, etc.).
Radiographs: Should there be a possible bone fracture.
Death distribution in three dimensions. caused by a large-vessel, brain, or spinal cord injury early (within minutes). The golden hour, which is the second peak (within hours) of hemorrhage, is the time when there is the highest chance that receiving medical attention quickly can avert death. Sepsis-related third peak (within days to weeks).

Surgery - Appendicitis
Introduction
acute vermiform appendix infection and inflammation.
AE T IOLOGY
initiated by lymphoid hyperplasia, oedema, or luminal blockage caused by a faecolith (inspissated feces). The less common causes of luminal blockage are caecal cancer and helminth infections.
Epidemiology
One of the most prevalent emergency surgical diagnoses in the UK, with a 7% lifetime risk, can occur at any age, with a peak prevalence in the second and third decades.
H HISTORY
Typical presentation (less than 50% of cases): Pain in the abdomen (typically subsiding after 72 hours), diffuse at first, periumbilical, and colicky (visceral pain subsiding after a few hours). Sharp pain that is restricted to the RIF develops (somatic pain as parietal peritoneum involvement). The most prevalent symptoms are nausea and anorexia. It's possible to throw up.
Other possible manifestations include pain in the lower abdomen (pelvic appendix), right upper quadrant (long appendix), or right flank (retrocaecal appendix). may be linked to frequent urination or loose stools as a result of the inflamed appendix irritating the bladder or colon.
Examination
Facial flush, tachycardia, and mild pyrexia.
Often, rebound tenderness (visible on percussion) and guarding are present along a line that runs from the umbilicus to the anterior superior iliac spine, or McBurney's point, where the intensity of the abdominal pain is greatest.
Pressure applied over the left iliac fossa causes pain in the right iliac fossa, which is known as Rovsing's sign.
Pathogenesis
Transmurally propagating intestinal flora and inflammation are caused by luminal blockage. The swelling causes end artery blockage and thrombosis, resulting in gangrene and necrosis of the appendix. If treatment is not received, the inflammation may become localized by omentumor bowel loops, resulting in an appendix mass or abscess, or it may rupture with peritonitis. Histology may occasionally reveal a carcinoid tumor; if this is larger than 1-2 cm, a right hemicolectomy is recommended.
Investigational studies
A clinical diagnosis of appendicitis is common.
Blood: "WCC and CRP, LFTs, amylase (to check for pancreatitis and biliary pathology), U&Es."
Urine: For pregnancy tests in women of childbearing age, microscopy, culture, and sensitivity.
Imaging: Ultrasound (helpful in skilled hands, frequently difficult to visualize appendix; can reveal other pathology, such as ovarian cysts). CT requires a large amount of radiation exposure but has a 94% sensitivity and 95% specificity. It is particularly helpful if additional disease, such as diverticulitis, is a concern.
Accurate diagnosis and therapy are made possible by diagnostic laparoscopy.
Management
General: intravenous fluids, broad-spectrum antibiotics before and after surgery in the event of severe sepsis symptoms. If there are any unclear symptoms or indications, keep an eye on them and check them frequently.
Surgery: Laparoscopic or open appendicectomies (see Procedures).
After surgery: Antibiotics may be continued, particularly if the appendix is punctured or gangrenous.
Appendiceal abscess: Drainage can be done intraoperatively (with appendicectomy if safe) or percutaneously (with ultrasound or CT guidance, for example). In the event of a clinical deterioration, management of an appendiceal mass may involve periodic reassessment, parenteral fluids, antibiotics, and non-operative treatment. Weeks after the initial procedure, an interval appendicectomy may be done (Ochsner–Sherren method). If an adult does not undergo this, a barium enema or colonoscopy ought to be carried out in order to rule out a right colon malignancy.
Complications
Appendix abscess, perforation, peritonitis, inflammatory mass, and infrequently, portal pyaemia.
Following surgery, there may be an appendix stump faecal fistula, an abscess, an ileus, and wound infection.
Prognosis
An appendixectomy can be cured. It may be fatal if left untreated. The extremely young, the elderly, and pregnant women have greater rates of morbidity and mortality, making diagnosis more challenging in these situations.

Surgery - Gastrointestinal Perforation
Introduction
GI tract wall perforation resulting in bowel contents spilling out.
Etiology
Perforated duodenum or gastric ulcers are the most frequent gastroduodenal conditions; gastric cancer (1-2%) is less common.
In the large intestine, diverticulitis and colon cancer account for the majority of cases (80%); an appendix perforation is a common consequence of appendicitis. Additional conditions include trauma, radiation enteritis, volvulus, ulcerative colitis (toxic megacolon), post-operative anastomotic leaks, and colonoscopy complications.
Rarely, small bowel: radiation enteritis, lymphoma, Crohn's disease, infection (typhoid, TB), trauma.
Boerhaave's syndrome (oesophagus): refer to oesophageal perforation. Iatrogenic perforation happens more frequently during stricture dilatation than it does during OGD.
Epidemiology
Cause determines incidence. On the other hand, bowel perforation-related stomach pain is a somewhat common and potentially fatal emergency.
History
Depending on the reason. Abdominal pain is generally linked to nausea and vomiting, with a fast onset.
Examination
The patient is ill, exhibiting symptoms of either localized or generalized peritonitis, including diminished or absent bowel sounds, guarding, and rigidity in the abdomen. Overlying gas causes the loss of liver dullness. pallor, pyrexia, shock, and dehydration symptoms.
Investigational studies
Blood: ABGs, coagulation, amylase (levels may be elevated in perforation), FBC, U&Es, and LFT.
Erect CXR: In 70% of patients, a perforated peptic ulcer will show gas behind the diaphragm (see Fig. 4).
AXR: Tissues may exhibit aberrant gas shadows. Gas on each side of the colon wall is referred to as Rigler's sign; alternatively, intraperitoneal gas can be seen on a lateral decubitus film.
CT scan: May identify underlying pathology and is extremely sensitive for free intraperitoneal gas.
Management
Intravenous rehydration, correction of electrolyte imbalances, broad-spectrum IV antibiotics, analgesics, urine catheter, and central line as needed are all part of resuscitation.
Conservative: Saved for patients with few symptoms, little contamination, or a high risk of anesthesia. In order to treat gastroduodenal perforations, high-dose PPIs, IV fluids, antibiotics, NG tubes, and monitoring are all recommended.
Operative: Gastroduodenal: Peritoneal lavage and laparoscopy or laparotomy An omental patch is applied once the puncture is sealed. A biopsy of a stomach ulcer is necessary to check for malignancy. Although gastroduodenal anastomosis and Billroth I partial gastrectomy can be performed, closure is more challenging than duodenal ulcers. If positive, post-operative elimination of Helicobacter pylori.
Large bowel: Perineural lavage and site of perforation detection via laparoscopy or laparotomy. removal of the affected colon, typically as a part of a Hartmann's procedure, along with the creation of an end colostomy, exteriorization as a mucous fistula, and closure of the distal stump. Resection and primary anastomosis combined with a failing ileostomy are the alternative. Resection and a primary anastomosis may be possible with a right colon perforation. A subtotal colectomy with a terminal ileostomy and preservation of the rectal stump is done in cases with toxic megacolon of ulcerative colitis (allows future repair of ileoanal pouch).
Complications
mortality, fistula development, peritonitis, and sepsis.
Prognosis
Gastroduodenal: Perforated gastric ulcers have a higher morbidity and death rate than duodenal ulcers, and the prognosis for perforated gastric carcinomas is extremely bad.
Greater prognosis with localized or restricted contamination in the large bowel. The mortality rate from fecal peritonitis is more than 50%.
Introduction
GI tract wall perforation resulting in bowel contents spilling out.
Etiology
Perforated duodenum or gastric ulcers are the most frequent gastroduodenal conditions; gastric cancer (1-2%) is less common.
In the large intestine, diverticulitis and colon cancer account for the majority of cases (80%); an appendix perforation is a common consequence of appendicitis. Additional conditions include trauma, radiation enteritis, volvulus, ulcerative colitis (toxic megacolon), post-operative anastomotic leaks, and colonoscopy complications.
Rarely, small bowel: radiation enteritis, lymphoma, Crohn's disease, infection (typhoid, TB), trauma.
Boerhaave's syndrome (oesophagus): refer to oesophageal perforation. Iatrogenic perforation happens more frequently during stricture dilatation than it does during OGD.
Epidemiology
Cause determines incidence. On the other hand, bowel perforation-related stomach pain is a somewhat common and potentially fatal emergency.
History
Depending on the reason. Abdominal pain is generally linked to nausea and vomiting, with a fast onset.
Examination
The patient is ill, exhibiting symptoms of either localized or generalized peritonitis, including diminished or absent bowel sounds, guarding, and rigidity in the abdomen. Overlying gas causes the loss of liver dullness. pallor, pyrexia, shock, and dehydration symptoms.
Investigational studies
Blood: ABGs, coagulation, amylase (levels may be elevated in perforation), FBC, U&Es, and LFT.
Erect CXR: In 70% of patients, a perforated peptic ulcer will show gas behind the diaphragm (see Fig. 4).
AXR: Tissues may exhibit aberrant gas shadows. Gas on each side of the colon wall is referred to as Rigler's sign; alternatively, intraperitoneal gas can be seen on a lateral decubitus film.
CT scan: May identify underlying pathology and is extremely sensitive for free intraperitoneal gas.
Management
Intravenous rehydration, correction of electrolyte imbalances, broad-spectrum IV antibiotics, analgesics, urine catheter, and central line as needed are all part of resuscitation.
Conservative: Saved for patients with few symptoms, little contamination, or a high risk of anesthesia. In order to treat gastroduodenal perforations, high-dose PPIs, IV fluids, antibiotics, NG tubes, and monitoring are all recommended.
Operative: Gastroduodenal: Peritoneal lavage and laparoscopy or laparotomy An omental patch is applied once the puncture is sealed. A biopsy of a stomach ulcer is necessary to check for malignancy. Although gastroduodenal anastomosis and Billroth I partial gastrectomy can be performed, closure is more challenging than duodenal ulcers. If positive, post-operative elimination of Helicobacter pylori.

Surgery - Gastrointestinal Stromal Tumors
Introduction
Mesenchymal tumors of the intestines that could be produced from Cajal interstitial cells or pacemaker cells connected to the Auerbach's plexus that regulate peristalsis. Display an array of malignant potential ranging from extremely low risk to overtly malignant.
Etiology
typified by mutations in either PDGFR-a (platelet-derived growth factor receptor alpha, 5–10%) or KIT (75–80%, CD117), which together activate receptor tyrosine kinase signaling pathways and cause cell division.
Risk Factors
Neurofibromatosis type I, familial GIST syndrome, and Carney's triad.
Epidemiology
Annually, there are 11–15 cases per million and 129 cases of prevalence. Male to female, a large age range, with 75% of respondents being over 50 (median age 58).
History
Possible asymptomatic or inadvertent detection during imaging, laparotomy, or endoscopy. GI bleeding (70%) is one of the other manifestations, along with bloating and abdominal pain (57%), bowel blockage (30%), satiety and weight loss (22%), palpable mass (13%), and, less frequently, rupture.
Examination
Results vary depending on the site, complexity, and size. can occur anywhere in the gastrointestinal system, with the stomach accounting for 50% of cases, small bowel for 25%, colon/rectum for 10%, mesentery, omentum and retroperitoneum for 10%, and oesophagus for 5%.
Investigational studies
Endoscopy: May show a submucosal tumor; biopsies are often negative unless they are "inkwell" biopsies. Endoscopic ultrasound: a traditionally hypoechoic mass that is next to the propria or muscularis mucosa. In general, perioperative or percutaneous biopsy is not advised due to the possibility of tumor rupture and dissemination.
Imaging: 18FDG PET scanning and CT abdominal imaging. in order to pinpoint the tumor's location.
Immunohistochemistry: CD34 (60–70%) and KIT (95%), positive.
Management
The preferred course of treatment for non-metastatic GISTs is surgical resection. If at all possible, complete excision should be tried as it provides a strong probability of recovery. Lymphadenectomy on a routine basis is not advised. For small-to-intermediate tumors, laparoscopic excision is an option. Adjuvant imatinib and neoadjuvent are undergoing clinical studies.
advanced illness To treat advanced or metastatic GISTs, imatinib binds competitively to the ATP binding site and inhibits the receptor tyrosine kinases KIT, PDGFRA, and BCR-ABL. Up to 85% of patients with a median life longer than 36 months had disease control. As the condition worsens, it may be necessary to increase the dosage or to think about surgically removing liver metastases or using radiofrequency ablation. When imatinib treatment is ineffective for advanced cases, sunitinib is given.
Complications
Tumor rupture should be avoided during surgery to reduce the chance of seeding. Haematogenous and local spread modes exist. There can be metastases to the liver or transperitoneum, lung or bone in more advanced cases, and rarely, lymph nodes.
Prognosis
Malignant potential exists in almost all GISTs. Prognostic markers include size (>5–10 cm, more malignant potential), mitotic activity (>5 mitoses per 50 HPFs), completeness of resection, and placement (e.g., stomach more favorable result than small bowel).

Surgery - Femoral Hernia
Introduction
the unusual outgrowth of a peritoneal sac via the femoral canal, frequently containing contents from the abdomen.
Etiology
The structure of the femoral canal, which has four distinct and impervious borders, is the predisposing factor. These limits are the inguinal ligament anteriorly, the lacunar ligament medially, the pectineal (Cooper's) ligament and pubic bone posteriorly, and the femoral vein laterally. Usually, the canal simply contains a lymph node (Cloquet's node) and loose connective tissue.
R isk Factors
Women's femoral canals are wider due to the larger angle between the inguinal ligament and the pectineal portion of the pubic bone. Increased intra-abdominal pressure, such as from coughing or straining because of constipation or prostatism, increases the risk of hernia formation.
Epidemiology
25 times less frequent than inguinal hernias, with a female to male ratio of 4:1.
H HISTORY
Show up with a possible discomfort-causing lump or bulge in the groin. Femoral hernias frequently go undiagnosed until they become strangulated or obstructed because of their tiny size and tight necks. Up to 80% of cases of femoral hernias present as emergencies with pain, distention of the abdomen, nausea, and vomiting.
Examination
Upon close examination, a swelling beneath and to the side of the pubic tubercle will be visible in the groin (but if it is significant, it may also spread up and across the inguinal ligament). The cough impulse above the inguinal ring is absent. The hernia may be extremely sensitive if the victim is imprisoned or strangled. stomach distension and tinkling bowel noises if obstructed.
Differentials include femoral aneurysm, groin or psoas abscess, hydrocoele or lipoma of the spermatic cord (in men), inguinal hernia, lymphadenopathy, and saphaena varix.
Investigational studies
Blood: ABG (for metabolic acidosis in intestinal ischaemia), FBC, U&Es, coagulation, G&S.
Visualization: When a different diagnosis is suspected, an AXR may reveal intestinal blockage or USS; nevertheless, if an imprisoned hernia is suspected, surgery should not be postponed. Could be an unintentional discovery, like a CT scan. When a herniogram is suspected, it can be done electively.
Management
Emergency care includes resuscitation with electrolyte balance correction and hydration, implantation of an NG tube in the event of vomiting, administration of antibiotics in the event of sepsis, and surgical repair as the last resort.
Surgery: The basic steps are to dissect the sac, examine and reduce its contents, remove the sac, and repair the defect. Typically, this is done by approximating the pectineal and inguinal ligaments with non-absorbable sutures (a procedure known as Cooper's ligament repair). An alternative is to insert a mesh plug into the femoral canal without using any tension.
It is possible to perform laparoscopic mesh repair using TAPP or TEP techniques. Three primary methods are available for open surgery:
1. Low transverse incision over hernia (Lockwood) (elective surgery).
2. Transinguinal (Lotheissen) incision via the transversalis fascia, inguinal canal, external oblique, and above and parallel to the inguinal ligament (may have a greater recurrence rate).
3. The high (McEvedy) technique involves splitting the transversalis fascia, opening the rectus sheath, retracting the rectus medially, and making an oblique, paramedian, or unilateral Pfannenstiel incision to reveal the femoral canal. If strangulation is suspected, this is used. The sac's contents are examined after it is opened. If they are viable, they are decreased, and if nonviable bowel is present, it is removed (this may require resection if a high approach is not taken).
Complications
Femoral hernias frequently strangulate, which can cause gangrene, ischaemia, and intestinal blockage. Surgical resection may be required in some cases.
Surgery: Bleeding (an anomalous obturator artery may be wounded if the lacunar ligament is cut to enlarge the canal); there is a chance that the femoral vein may narrow during surgery, which increases the risk of seroma, infection, and venous thrombosis.
When timely and adequate surgery is performed, the prognosis for is generally good. Recurrence following repair is uncommon (<3%).
