Operative procedures and tobacco use
Smoking tobacco elevates the risks associated with anesthesia and other surgical complications. A sixfold increase in postoperative respiratory complications occurs in patients who smoke more than ten cigarettes daily.
Consequences of smoking
• Diminution of overall and particular immune activity due to decreased neutrophil chemotaxis and diminished efficacy of natural killer (NK) cells.
• Increased platelet aggregation—likely elucidating the elevated risk of perioperative acute myocardial infarction (MI) and cerebrovascular accident (CVA) in smokers.
• Diminished oxygen (O2) transport capacity of blood per unit volume resulting from the presence of carboxyhemoglobin, hence elevating the risk of tissue hypoxia in vulnerable organs.
Upper aerodigestive mucosal secretions.
This first exacerbates after cessation of smoking until the persistent effects on the mucosa dissipate.
Diminished mucociliary escalator efficacy.
Decreased lung compliance and elevated 'closing volume' of the small airways heighten the risk of air trapping, particularly in the supine position during the postoperative phase.
Ceasing tobacco use
Within 48 hours, carboxyhemoglobin is eliminated from the bloodstream, and platelet aggregation commences its return to normalcy.
• Neutrophil, macrophage, and NK cell functionality enhances within 7 days. Mucus production briefly rises, although the functionality of the mucociliary escalator may take up to six weeks to restore, resulting in a 'rebound' effect.
• Within six weeks, upper aerodigestive function reverts to baseline levels, and lung dynamics improve to 'normal' levels, contingent upon the severity of fixed parenchymal illness. The ideal cessation period for smoking is a minimum of 6 weeks before surgery; however, at least 7 days is necessary to mitigate the rebound effects on upper aerodigestive tract function.
Alleviating the consequences of smoking during the postoperative phase
Active and recently ceased smokers require heightened vigilance to mitigate the dangers linked to smoking and surgical procedures.
• Maintain adequate hydration for patients until oral intake is restored.
• Implement thromboembolic prophylaxis in the majority of instances. Utilize preoperative chest physiotherapy and provide instruction on breathing and coughing strategies.
• mobilize promptly following the operation.
• Evaluate the implementation of epidural anesthesia to enhance adherence to postoperative physiotherapy. Administer nebulized saline (5 mL four times daily) preoperatively and postoperatively. Ensure the efficacy of post-operative analgesia.
Infection of the respiratory tract
An active respiratory tract illness may warrant the cancellation of elective patients; therefore, inquire about cough, fever, and sputum. However, small colds and nasal discharge may not preclude general anesthesia.
• If a respiratory tract infection is suspected in the patient, assess vital signs, inflammatory markers, and do a chest X-ray. Elective patients should be rescheduled and instructed to return in two weeks if their symptoms have improved.
• Administer antibiotics exclusively to individuals with suspected bacterial infections, as the majority of acute respiratory tract infections are viral in nature. Asthma
• Evaluate the severity of asthma by inquiring about hospital admissions, inhaler usage, nebulizer treatments, peak expiratory flow rates (PEFRs), and home oxygen therapy.
• Elective surgery should preferably align with the resolution of symptoms. Identify patients undergoing prolonged steroid treatment.
• It is occasionally feasible to schedule surgery to align with a decrease in steroid dosage, although this necessitates several weeks' advance notice. Patients receiving more than 5mg of daily prednisolone and undergoing inpatient surgery or presenting with sepsis should be administered an equivalent dosage of intravenous hydrocortisone to prevent adrenal suppression and the potential onset of an Addisonian crisis.Patients undergoing general anesthesia typically exhibit a decline in pulmonary function.Prophylactically augment their standard therapy by transitioning from inhalers to nebulizers and enhancing the frequency of administration.
Chronic obstructive pulmonary disease (COPD) If dyspnea is the primary symptom and the patient has COPD, obtain lung function testing, including arterial blood gases. Admitting these patients many days in advance for physiotherapy, education, and nebulization can decrease the duration of hospitalization. Patients undergoing general anesthesia typically exhibit a decline in pulmonary function. Prophylactically augment their standard therapy by transitioning from inhalers to nebulizers and enhancing the frequency of administration. Administer nebulized saline at a dosage of 5 mL every 6 hours and provide humidified oxygen whenever feasible to avert mucus clogging. Administer chest physiotherapy to the patient bi-daily. Verify that the patient is utilizing their standard inhalers and contemplate transitioning to nebulizers for significant surgical procedures.

Surgery - Cardiac surgery and cardiovascular disease
Ischemic heart disease
Risk factors encompass male individuals over 45 years, female individuals over 55 years, a familial history of early myocardial infarction, current or treated hypertension, smoking, diabetes mellitus, and elevated cholesterol levels.
Evaluate severity—measure exercise tolerance; inquire about palpitations, orthopnea, utilization of anti-anginals, history of myocardial infarction, percutaneous coronary intervention, or coronary artery bypass grafting. The ECG is the primary regular screening test; yet, it appears normal in approximately one-third of individuals with confirmed ischaemia.
Symptomatic patients scheduled for major surgery should be consulted with a cardiologist to optimize their meds.
Myocardial infarction
The likelihood of a perioperative myocardial infarction is associated with previous medical history and risk factors. • Overall population incidence following abdominal surgery: 0.5%. • Incidence of pre-existing cardiovascular symptoms: 2%. • Incidence of prior myocardial infarction (MI): 5–10%. • Incidence following recent myocardial infarction: 25% (70% will succumb to reinfarction).
Methods for mitigating risk
Non-urgent surgery should be postponed for a minimum of six months after an acute myocardial infarction and potentially after acute ischemia.
Cancer surgery may be performed if the likelihood of disease progression is deemed to surpass the perioperative mortality rate.
Continue all standard cardiovascular medications up to and during surgery. Manage any emergent angina symptoms if surgery is required.
Continue antiplatelet therapy if not contraindicated.
Consider engaging critical care services (HDU) during the perioperative phase.
Valvular cardiac pathology
Cardiac murmurs are prevalent.
Solicit a transthoracic echocardiography (TTE) to assess the lesion and confer with a cardiologist on the anomalies.
Severe aortic stenosis presents a significant mortality risk; elective surgery should be deferred. High-gradient aortic stenosis is related with a 10% mortality rate during non-cardiac surgery.
Severe mitral stenosis may result in pulmonary edema and cardiac failure; hence, significant elective surgery should be deferred until the defect is rectified.
Aortic regurgitation (AR) necessitates management of fluid balance and heart rate. Antibiotic prophylaxis is indicated, however the procedure may proceed. Mitral regurgitation (MR) ought to be treated with diuretics and vasodilators. Left ventricular (LV) function is often exaggerated in.
Prosthetic valves present numerous complications. Mechanical valves necessitate anticoagulation. Discontinue warfarin five days before to surgery and initiate heparin bridging once the international normalized ratio (INR) falls below therapeutic levels.
Cease IV heparin 2 to 6 hours before to surgery and reinstate it as soon as postoperative bleeding is adequately controlled, until the INR reaches therapeutic levels.
Thrombosis is more probable in the presence of mechanical valves, compromised left ventricular (LV) function, a history of thromboembolic disease, and to a lesser extent in rate-controlled atrial fibrillation (AF).
In surgical procedures addressing life-threatening hemorrhage, such as from a bleeding peptic ulcer or intracranial hemorrhage, it may be essential to reverse anticoagulation for multiple days. Collaborate closely with cardiology. Prosthetic valves no longer necessitate antibiotic prophylaxis for procedures that induce bacteraemias; if uncertain, consult with cardiology.
Hypertension arterial
Preoperative management of blood pressure may diminish the propensity for perioperative ischemia. If hypertension is severe (>180 mmHg), surgical intervention should be postponed until adequate control is achieved. • Evaluate current antihypertensive management or initiate treatment: consult with the anaesthetist.
Examine for indications of end-organ damage (renal, neurological) and concomitant cardiovascular disease. • Investigate uncommon yet significant etiologies: phaeochromocytoma, hyperaldosteronism, coarctation of the aorta, renal artery stenosis.
Congestive heart failure
Heart failure correlates with adverse outcomes in non-cardiac surgery. Risk factors encompass ischemic and valvular heart disease.
• Identify: S3, pedal edema, elevated jugular venous pressure (JVP), bibasal crepitations. Request a chest X-ray (CXR) if suspicion is present.
Cardiac arrhythmias
Arrhythmias and conduction abnormalities are prevalent. Asymptomatic arrhythmias do not correlate with an elevated risk of cardiac problems; however, it is essential to investigate potential underlying diseases, such as ischemic heart disease, medication toxicity, and metabolic disturbances. High-grade conduction problems, such as total heart block, necessitate consultation with a cardiologist. Pacing may be warranted. Patients with a history of atrial fibrillation, especially those with a prior embolic stroke or structural heart abnormality, typically receive warfarin therapy. Solicit a cardiology evaluation preoperatively if rate control is inadequate.
• Permanent pacemakers or implantable cardioverter-defibrillators (ICDs). Diathermy may induce a pacemaker reset, entirely block pacing, and activate ICD discharge. Pacemakers and implantable cardioverter-defibrillators (ICDs) must be assessed by a cardiac technician both preoperatively and postoperatively. Pacemakers must be adjusted to fixed-rate pacing during surgery and subsequently reset postoperatively. ICDs must be deactivated to avert discharge, and external defibrillator pads should be placed on the patient.
When defibrillation or synchronized cardioversion is necessary, position the paddles as far as feasible from the pacemaker or ICD. The specific sort of diathermy employed must be taken into account. Monopolar is not unequivocally contraindicated; nevertheless, bipolar may be more advantageous.

Diabetes: Specific Perioperative Risks
• Hypoglycemia, hyperglycemia, or ketoacidosis.
• Underlying diabetes mellitus-related comorbidities are frequently unrecognized (e.g., mild renal impairment, small-vessel coronary and cerebrovascular disease, mild autonomic neuropathy with concomitant diminished cardiovascular homeostatic responses).
• Susceptibility to infection and impaired wound healing. Increased sensitivity to pressure-induced skin necrosis.
Management of the diabetic patient
• Notify the anaesthetist, diabetologist, and any specialists engaged in the patient's continuous care, such as nephrologists.
• Determine whether the patient is orally managed, insulin-dependent (low or high demand), or brittle insulin-dependent, as the risk of perioperative complications escalates with each category. Diabetics should be prioritized on surgical schedules to facilitate predictable blood sugar management. Examine preoperative assessments for indications of further comorbidities. Ketoacidosis during the perioperative period is linked to significantly elevated morbidity and mortality and must be prevented at all costs.
Minor surgical procedure
• Administer oral medication as per standard regimen. • Insulin-controlled: discontinue preoperative insulin on the day of surgery; test blood sugar every 4 hours; resume regular insulin once the oral diet is reinstated.
Minor surgical procedure
• For oral administration, discontinue long-acting hypoglycemics prior to surgery. Assess blood sugar levels every four hours. Initiate intravenous insulin therapy if blood sugar levels surpass 15 mmol/L. • Insulin-controlled—initiate intravenous insulin sliding scale preoperatively once the patient is nil per os (NBM) and maintain until a normal diet is reinstated. Verify blood sugar levels every four hours. Reinitiate the standard insulin regimen (initially at fifty percent dosage) once the oral diet is established.
Urgent surgical intervention
• Verify the presence of pre-existing ketoacidosis. Utilize the medical treatment protocol to manage blood sugar levels and defer surgery until blood sugar is below 20 mmol/L, unless the situation is life-threatening. Utilize an intravenous insulin sliding scale for all patients to enhance blood sugar regulation. A standard IV sliding scale (soluble insulin with 5% glucose) is as follows: • Blood Sugar <4mmol />: administer infusion of 0.5U/h and consider medical evaluation.
• Blood Sugar 4–15 mmol/L: infusion 2.0 U/h
. • Blood sugar 15–20 mmol/L: provide infusion at 4.0 U/h.
• Blood sugar above 20 mmol/L: administer infusion of 4.0 U/h, consult the diabetology team, and contemplate treatment analogous to that for ketoacidosis.
Steroids: Specific Perioperative Risks
Oral steroids are utilized to manage various prevalent conditions, such as rheumatoid arthritis (RA), severe asthma, and chronic obstructive pulmonary disease (COPD). Steroids diminish neutrophil and fibroblast activity, impair immunological response, and induce lasting alterations in connective tissue. Prolonged administration of systemic steroids leads to adrenal suppression. Chronic steroid use is connected with the following issues. Addisonian (hypoadrenal) crisis
• Increased vulnerability to infection. • Inadequate wound healing, encompassing anastomotic leakage. • Osteoporosis. Patients utilizing long-term inhaled corticosteroids, such as for asthma and COPD, are not considered high risk due to negligible systemic absorption. Management of the patient receiving steroids: • If feasible, the steroid dosage should be reduced prior to surgery. Administer IV hydrocortisone 25–100 mg four times daily, approximately equivalent to 2.5–20 mg of prednisolone once daily, commencing on the morning before surgery and continuing until the patient can resume oral steroids.

Surgery - OCP (oral Contraceptive Pills)
Estrogen-containing contraceptive pills (OCPs) elevate the risk of thromboembolic illness in women who use them before undergoing surgery. Progesterone-only contraceptives seem to present minimal or no supplementary risk and may be maintained throughout surgical procedures. The elevation in risk correlates with the magnitude of the surgical procedure and the presence of comorbidities; recommendations are modified accordingly. •
Low-risk procedures, such as dentistry, day case, and minor laparoscopic surgeries. • Oral contraceptive pills may be resumed. • Moderate risk procedures include abdominal, orthopedic, and major breast surgeries. • Oral contraceptive pills should be ceased at least one month before elective surgery. • Urgent or emergency surgeries must be performed with comprehensive thromboprophylaxis (see to % Prophylaxis—antibiotics and thromboprophylaxis, pp. 98–9). • High-risk procedures include pelvic and lower limb orthopaedic surgeries, as well as cancer surgeries. • Oral contraceptive pills (oCP) should be ceased at least one month before elective surgery. • Urgent or emergency surgeries necessitate the implementation of prolonged thromboprophylaxis, which includes both antibiotics and thromboprophylaxis.

Surgery - Assessment of peripheral vascular disease
Placement and examination The patient ought to be assessed in a heated setting while at rest. Ensure to assess the pulse and blood pressure, inspect the belly for aneurysms and scars, and conduct a comprehensive cardiovascular examination, including all peripheral pulses, heart sounds, and carotid auscultation.
Examine the leg in the supine position, subsequently elevated (passively), and ultimately in a dependent position. Fully expose the leg, encompassing the foot or hand, to facilitate a comprehensive examination and eliminate any bandages. The patient should be assessed in an upright position for venous disease. During supine examination,
observe the following:
Appearance Are there any regions with confirmed skin necrosis (dry gangrene, such as the tips of fingers or toes, interdigital spaces, or the heel of the foot)? Are there alterations in chronic venous stasis (such as varicosities, venous dermatitis, lipodermatosclerosis, or leg ulcers)?
Color - Waxy white indicates critical or acute ischaemia; blue and mottled coloration denotes potentially irreversible acute ischaemia; dark red or purple signifies chronic ischaemia.
Color alterations occur with positional modifications. Observe the angle at which the skin of the limb becomes pale when lifted passively (Buerger’s test). Normal extremities may have no blanching whatsoever. An angle of 15° or less indicates significant ischaemia. Observe the occurrence and latency of color change when the limb is in a dependent position. Ischaemic limbs gradually assume a vivid scarlet hue (reactive hyperaemia).
Ulcers-What is the site (digital or pedal) indicative of arterial disease? Ensure to examine the areas between the toes and fingers, as well as the plantar surface of the foot, particularly in cases of diabetes.
• Examination of venous structures. Assist the patient in standing upright. Examine for varicose veins. Are they located within the long saphenous or short saphenous distribution?
Palpation
• Temperature. Is the skin seen as chilly or warm? Is there a transitional phase? Compression and filling of skin capillaries. The standard is 2 seconds or fewer. A delay over 5 seconds indicates markedly diminished perfusion.
• Peripheral pulsations. Commence with the most proximal (major) vessels and go distally. Document whether the pulse is normal (++), diminished (+), or missing (–). Document any discernible excitement.
• In venous pathology, assessments of venous competence may be conducted (% Varicose veins). Surgical grafts. Examine the pathway of any surgical grafts and document the existence or nonexistence of pulses. Auscultation Assess for bruits. Are there bruits in the proximal vessels indicative of stenosis?
Inquiries Handheld Doppler (at the bedside), followed by Duplex ultrasound or CT angiography, are the primary modalities for examining vascular disease.
Portable Doppler ultrasonography • A simple and portable "bedside" assessment for preliminary evaluation. • used to: • Verify the existence of flow within a vessel or graft. • Assess the ankle-brachial pressure index (ABPI). Assess the existence of venous reflux.
Duplex Ultrasound (USS) • Integrates two-dimensional (2D) ultrasound imaging with Doppler-derived flow, shown in color and superimposed in real time. • Arterial duplex: utilized for the evaluation of stenoses and occlusions. Venous duplex: utilized for evaluating reflux or thrombosis in deep and superficial veins.
Computed Tomography Angiography Requires a multi-slice rapid acquisition ('helical'/'spiral') scanner. Images obtained during the arterial and/or venous phase following intravenous contrast administration.
Three-dimensional (3D) reconstruction facilitates the generation of 'virtual angiogram' images. This process is rapid, non-invasive, and comparatively safe. Utilizes iodinated contrast, which is nephrotoxic (relatively contraindicated in renal impairment) and poses a minor risk of allergic reaction. The presence of vessel wall calcification may hinder the visibility of the lumen.
Digital subtraction angiography (DSA) involves X-ray imaging subsequent to the injection of contrast material into the target vessel, effectively eliminating background structures (such as bone) to render the vessel lumen in black. This technique is primarily employed when endovascular intervention is necessary during the same procedure or when prior investigations yield inconclusive results. It is an invasive procedure that necessitates arterial puncture, which carries inherent risks, including the potential for false aneurysm or retroperitoneal hemorrhage associated with groin puncture. • Necessitates iodinated contrast, necessitating vigilance in cases of renal impairment and allergies.
Magnetic resonance angiography produces images of the arterial network by detecting arterial flow throughout the scanning process. • Safe and non-invasive: does not necessitate iodinated contrast, typically employing gadolinium to accentuate circulating blood. • Often overestimates the extent of stenosis due to the underrepresentation of very low flow.
Placement and examination The patient ought to be assessed in a heated setting while at rest. Ensure to assess the pulse and blood pressure, inspect the belly for aneurysms and scars, and conduct a comprehensive cardiovascular examination, including all peripheral pulses, heart sounds, and carotid auscultation.
Examine the leg in the supine position, subsequently elevated (passively), and ultimately in a dependent position. Fully expose the leg, encompassing the foot or hand, to facilitate a comprehensive examination and eliminate any bandages. The patient should be assessed in an upright position for venous disease. During supine examination,
observe the following:
Appearance Are there any regions with confirmed skin necrosis (dry gangrene, such as the tips of fingers or toes, interdigital spaces, or the heel of the foot)? Are there alterations in chronic venous stasis (such as varicosities, venous dermatitis, lipodermatosclerosis, or leg ulcers)?
Color - Waxy white indicates critical or acute ischaemia; blue and mottled coloration denotes potentially irreversible acute ischaemia; dark red or purple signifies chronic ischaemia.
Color alterations occur with positional modifications. Observe the angle at which the skin of the limb becomes pale when lifted passively (Buerger’s test). Normal extremities may have no blanching whatsoever. An angle of 15° or less indicates significant ischaemia. Observe the occurrence and latency of color change when the limb is in a dependent position. Ischaemic limbs gradually assume a vivid scarlet hue (reactive hyperaemia).
Ulcers-What is the site (digital or pedal) indicative of arterial disease? Ensure to examine the areas between the toes and fingers, as well as the plantar surface of the foot, particularly in cases of diabetes.
• Examination of venous structures. Assist the patient in standing upright. Examine for varicose veins. Are they located within the long saphenous or short saphenous distribution?
Palpation
• Temperature. Is the skin seen as chilly or warm? Is there a transitional phase? Compression and filling of skin capillaries. The standard is 2 seconds or fewer. A delay over 5 seconds indicates markedly diminished perfusion.
• Peripheral pulsations. Commence with the most proximal (major) vessels and go distally. Document whether the pulse is normal (++), diminished (+), or missing (–). Document any discernible excitement.
• In venous pathology, assessments of venous competence may be conducted (% Varicose veins). Surgical grafts. Examine the pathway of any surgical grafts and document the existence or nonexistence of pulses. Auscultation Assess for bruits. Are there bruits in the proximal vessels indicative of stenosis?

Surgery -Assessment of Breast Pathology
The fundamental principle of breast evaluation is Triple Assessment: This includes a physical examination, subsequent radiological imaging, and biopsy (either fine needle or core biopsy).
Clinical assessment
Placement and examination
Breasts are optimally assessed in a semi-recumbent position followed by an upright position. Initially, the arms are positioned at the sides in a semi-recumbent posture. Subsequently, they ought to be examined in an upright position, with hands placed on the hips (first in a relaxed state and subsequently applying forceful pressure on the hips to engage the pectoral muscles), and ultimately abducted gradually above the head.
Inspection is essential and should focus on the following aspects.
• comprehensive symmetry and placement. Are the breasts of identical size? Is there a deformity resulting from an underlying disease? Is the position standard? • Dermal appearance. Is the skin erythematous or edematous? Is there a fixed form of lymphoedema in the skin known as 'peau d’orange'? Are there any scars from prior surgery?
• Dermal adhesion. Is the skin mobile when the arms are elevated? Tethering indicates the presence of underlying intraparenchymal scarring or a tumor.
Nipples. Are the nipples retracted, displaced, or ulcerated (indicative of retroareolar tumor or infection)? Is there any excretion?
Palpation
For palpation, the hands should be repositioned to the hips, and the patient may recline in a semi-recumbent position once again. Employ the flat surfaces of all four fingers simultaneously. Initially palpate the 'normal' breast. Be systematic and avoid 'kneading' the breast. A typical sequence is: upper outer quadrant; lower outer quadrant; lower inner quadrant; higher inner quadrant; center (retroareolar) region; supraclavicular fossa; and axillary region. Essential characteristics to consider comprise:
• Tangible mass. Is it hard, uneven, and fixed (cancer) or smooth, spherical, and movable (cysts or fibroadenoma)? Diffuse nodularity. Characteristic of a benign condition. Discharge from the nipple upon probing of the central region. Blood indicates a tumor; pus indicates an infection; serous or milky fluid may be inconsequential.
• Axillary and supraclavicular lymphadenopathy. Is it multifocal and attached (cancer)? Ultrasound Imaging
• Simple to execute and devoid of discomfort— often conducted at a breast outpatient clinic. Avoids radiation exposure in young women.
• Extremely adept in distinguishing between solid tumors and cysts. Mammography is utilized for both population screening and diagnostic evaluation. Very unpleasant for the majority of women and entails a minimal radiation exposure.
• Capable of detecting imperceptible lesions
. • Capable of recognizing premalignant lesions, such as ductal carcinoma in situ (DCIS). Mammographic characteristics indicative of malignancy encompass spiculated microcalcifications, irregularities, and stellate outlines.
Biopsy Aspiration cytology
• Well-tolerated, facile to execute, and rapid to report—typically conducted within half a day at the breast outpatient clinic. • Lacks histological data; offers solely cellular information and depends on cellular atypia for malignancy diagnosis. • Fails to distinguish between invasive and in situ cancer. • Occasionally therapeutic for cysts. High sensitivity and specificity.
Guided core biopsy
• Conducted under ultrasound or mammographic supervision utilizing a Trucut® needle or comparable instrument. Can be performed under general anesthesia or local anesthesia. Delivers precise histological data—facilitates cancer grading. Capable of distinguishing between invasive cancer and carcinoma in situ. Extremely delicate and specific.
Alternative (less frequently utilized)
Computed tomography (CT) scanning is beneficial for evaluating significant local invasion and for regional and systemic staging.
CT positron emission tomography (PET) imaging
Valuable for examining ambiguous lesions and detecting unrecognized metastatic illness.
Magnetic Resonance Imaging (MRI) scanning
Periodically employed for diagnostic purposes, such as in women with breast implants.
Essential topics—breast anatomy
The breast consists of epithelial ductal tissue, epithelial secretory lobules, adipose tissue, and connective tissue. It is segmented into four quadrants and a peri- / retroareolar central zone for the clinical characterization of anomalies. The arterial supply originates from segmental perforators of the internal thoracic artery (ITA). Lymphatic drainage is crucial in the therapy of breast cancer.
• Non-pathological lymphatic drainage predominantly occurs to the axillary nodes.
• The medial half may occasionally drain to the internal mammary nodes. Axillary lymph nodes are categorized into three levels: Level 1 is located inferior to the pectoralis minor, Level 2 is situated posterior to it, and Level 3 is positioned superior to the pectoralis minor.

Surgery - Assessment of the neck region
Placement and examination
Position the patient upright at rest, ensuring the head is oriented straight ahead. Examine the neck from the anterior, lateral, and, if required, posterior perspectives.
• examine the neck in a stationary position and while swallowing (a glass of water). Inspect rotation to the left and right if required.
• Examine the neck while instructing the patient to protrude the tongue. Examination (criteria for assessment) Overall symmetry and nodules. Are there discernible lumps? Are they singular or plural? Is the mass positioned in or around the midline? Does the lump exhibit mobility when swallowing, indicating a potential thyroid-related lesion?
• Dermatological irregularities. Are there any ulcers or sinuses indicative of a chronic infection, such as tuberculosis?
• Related structures. Is there evidence of venous distension or observable collateral vessels? Examination by touch Adopt a systematic approach; palpate the cervical areas sequentially. Utilize both hands with the flat of the fingers to assess each side, but manipulate only one hand at a time to avoid 'cross-palpation.' A standard palpation sequence is: anterior triangle (bottom to top); submental region; submandibular region; posterior triangle (top to bottom); supraclavicular fossae; and parotid, preauricular, and postauricular regions. Repalpate the neck as the patient swallows a mouthful of water, focusing on the anterior triangle. Finally palpate the carotid arteries particularly.
• Mass. Is it singular or plural? Multiple strongly indicates lymphadenopathy. Is it precisely located along the midline, potentially associated with the thyroid? Does it exhibit movement during swallowing, typically indicating a thyroid-related issue? What are the overarching characteristics? Thyroid nodule. Is it one-sided or two-sided? Does it exhibit movement with tongue protrusion? Carotid arteries. Are they normal, ectatic, or aneurysmal? Supraclavicular fossae. Is there accompanying lymphadenopathy indicative of malignancy? Auscultation Auscultate the carotid arteries and any significant masses for bruits, indicating hypervascularity or stenosis.
Inquiries Ultrasonography
• Simple to execute and devoid of pain. Avoids exposure to radiation dosage.
• Extremely adept in distinguishing between solid tumors and cysts
Aspirational cytology
Simple to execute and rapid to document.
• Generally widely accepted in outpatient settings. Offers solely cellular information and depends on cellular atypia for the diagnosis of cancer. Does not furnish histology information.
• intermittently beneficial for cysts. High sensitivity and specificity. Contraindicated in cases of suspected vascular lesions. CT scanning is beneficial for evaluating substantial local invasion and for regional and systemic staging of tumors.
• Facilitates the assessment of the thorax in some thyroid neoplasms. CT PET scanning is occasionally employed to evaluate ambiguous lesions detected on standard CT and to find unanticipated metastatic illness. MRI scanning is beneficial for the comprehensive evaluation of local tumor invasion.

Surgery - Abdominal Investigations
Fecal occult blood testing may be chemical or immunological/quantitative—specifically, the quantitative fecal immunochemical test (qFIT). The primary application is as the initial community test for colorectal carcinoma, as outlined in the National Bowel Cancer Screening Programme.
Flexible sigmoidoscopy
• Minimal risk (perforation <1 in 10,000), typically conducted without sedation. • should visualize up to the descending colon. facilitates small therapeutic interventions (polypectomy, biopsy, injection). commonly employed for: diagnosis and evaluation of colitis colonic neoplasia, investigation anorectal hemorrhage.< />pan>
Colonoscopy: Low risk (perforation 1 in 1000); conducted with or without intravenous sedation or Entonox®; necessitates bowel preparation.
• The entire colon should be visualized in over 95% of cases. Permits minimal therapeutic interventions—polypectomy, including endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD), injection, tattoo marking, and biopsy. Applicable when comprehensive colonic evaluation is warranted or when colonic and/or terminal ileal pathology is suspected.
Transabdominal ultrasonography
Simple, secure, non-invasive, and eliminates radiation exposure. Common applications encompass: • 1° examination of the biliary tree for gallstones, bile duct dimensions, and liver parenchymal characteristics. • Detection of ovarian pathology, for instance, in cases of suspected appendicitis. Evaluation of the hepatic and splenic parenchyma. Detection of free fluid in abdominal trauma.
Computed Tomography scanning
• Simple and non-invasive; necessitates considerable radiation exposure and intravenous/oral contrast.
• Common applications encompass:
• Initial evaluation of all intra-abdominal masses.
• Staging of intra-abdominal and pelvic neoplasms.
• Examination of acute stomach pain (gaining prevalence).
• Examination of potential intestinal blockage.

Standard abdominal radiograph
• may detect intestinal blockage, urinary tract calculi, free intra-abdominal air, and intra-abdominal fluid.
The Barium/Gastrografin® enema can be performed as either a single contrast, where contrast material fills the colon to detect strictures and blockages, or a double contrast, which involves a dilute contrast and air to cover the mucosal surface of the colon, however the latter is currently hardly utilized.
Computed Tomography Colonography • Necessitates comprehensive bowel preparation and rectal catheter placement; entails considerable radiation exposure with intravenous or oral contrast.
• Generally employed as an alternative to colonoscopy when it is contraindicated or unfeasible, such as in cases of advanced age, frailty, known strictures, or unsuccessful colonoscopy attempts. Studies on intestinal transit
• Serial abdominal X-rays (AXR) are utilized to monitor the progression of ingested radio-opaque markers.
• They are employed to evaluate intestinal motility and transit duration. PET scanning involves the injection of a radioactive metabolic substrate to identify metabolically active tissues, such as malignancies or areas of inflammation/infection. It is combined with high-resolution CT scanning to accurately locate 'hot spots.' Commonly employed to detect unrecognized metastatic tumor deposits or to distinguish fibrosis from remaining tumor following surgery.
Physiological assessment
• Manometric evaluation of the esophagus, encompassing the lower esophageal sphincter and the anal canal. Pressure sensitivities of the esophagus and anal canal. pH assessment of the esophageal contents (either isolated or continuously over 24 hours).

Surgery -medical history and case presentation
Fundamentals
Begin with the individual's name, age, occupation, and the mode of presentation, such as Accident and Emergency (A&E), general practitioner referral, or admission from a clinic.
• Address all key aspects of the comprehensive medical history, as outlined below. Chief complaint This is a concise statement of the patient's primary symptoms, such as "right iliac fossa (RIF) pain," "abdominal pain and vomiting," or "bleeding per rectum (PR)."
• Do not record a diagnosis here in emergency admissions (e.g. ischemia leg). The referral diagnosis may prove to be incorrect. In elective admissions, it is appropriate to state, for example, 'elective admission for anterior resection for rectal cancer.' Chronology of presenting complaint This is a comprehensive delineation or examination of the primary symptom(s) and must encompass the pertinent systems inquiry
. • Begin with pertinent historical context to provide the framework for the presenting issue.
• Prioritize significant positives, such as "right-sided lower abdominal pain, exacerbated by movement and coughing, accompanied by anorexia."
• Include pertinent negatives, such as "no vomiting, no rectal bleeding." Clearly delineate the sequence of events. In a complex history or with numerous symptoms, utilize titles such as 'Previous Episodes/Operations for This Issue,' 'Current Episode,' and 'Results of Investigations.' Systematically summarize the findings of prior investigations: hematological analyses, microbiological assessments, histopathological examinations, radiological evaluations, and specialist diagnostic procedures. Previous medical history
• Enumerate particular medical diagnoses. • Include pertinent negatives, as it is prudent to inquire about cardiorespiratory and renal conditions that influence the patient's operative and anesthetic risk, such as ischemic heart disease (IHD), heart failure, chronic obstructive pulmonary disease (COPD), and renal impairment, in addition to those specific to the presenting complaint, such as neurological diagnoses in neurosurgery or ear, nose, and throat (ENT) conditions, as well as risk factors for atherosclerosis in vascular surgery. •
• Enumerate and date all prior operations. Inquire whether any prior complications associated with anaesthesia. Methodical investigation This is crucial, however frequently overlooked—it is essential to exclude alternative diagnoses (e.g., gynaecological etiology for lower abdomen pain) and to evaluate the patient's surgical and anaesthetic risk
. • Cardiovascular. Chest pain, exertional dyspnoea, orthopnoea, nocturnal dyspnoea, palpitations, edema of the ankles, strokes, transient ischemic attacks (TIAs), claudication.
• Respiratory. Dyspnea, cough, sputum production, wheezing, hemoptysis.
• Gastrointestinal. Anorexia, alteration in appetite, weight reduction (specify the amount and duration).
• Genitourinary (GU). Sexual activity, dyspareunia (intercourse-related pain), abnormal discharge, and last menstrual cycle (all female patients). Neurological. Three Fs: fits; fainting; humorous episodes. Nil by mouth (NBM) duration: what was the last time they consumed food or beverages? for urgent admissions Societal history Inquire regarding the individual responsible for the patient's care. Do they require assistance with mobility and/or activities of daily living?

profession.
Two Recommendations for Case Presentation
• Engage in practice. Each instance represents a potential presentation to an individual. Consistently establish the context appropriately. Commence with the individual's name, age, occupation (if elderly, include general fitness and independence), pertinent medical history, mode of referral, and presenting complaint, e.g., ‘78-year-old male, typically fit and well, with a previous history of open anterior resection for rectal adenocarcinoma, presents with a 3-day history of abdominal pain and vomiting.’ • Adhere to a chronological order. Commence with the onset of any pertinent prodrome or accompanying symptoms, as they are likely to constitute a significant aspect of the presenting history, e.g., 'He was in good health until... when he began suffering... the current symptoms commenced...
• Summarize the past medical history succinctly. Only elaborate on aspects that you genuinely believe may be pertinent to the diagnosis or management. •
• Initially, summarize the overall look and vital signs. Present the most critical findings initially, adhering to a methodical approach, such as 'upon examination . . . , during palpation . . . , upon percussion . . . , and by auscultation.'
• Concisely outline further systemic observations. Elaborate on them if they are directly pertinent to the diagnosis or treatment.
• Ultimately, condense and integrate. Attempt to categorize symptoms and indications into clinical patterns that inform the proposed diagnoses or differential diagnosis list.
• Be prepared to discuss which diagnostic or additional evaluation tests may be required.

Two Recommendations for Case Presentation
• Engage in practice. Each instance represents a potential presentation to an individual. Consistently establish the context appropriately. Commence with the individual's name, age, occupation (if elderly, include general fitness and independence), pertinent medical history, mode of referral, and presenting complaint, e.g., ‘78-year-old male, typically fit and well, with a previous history of open anterior resection for rectal adenocarcinoma, presents with a 3-day history of abdominal pain and vomiting.’ • Adhere to a chronological order. Commence with the onset of any pertinent prodrome or accompanying symptoms, as they are likely to constitute a significant aspect of the presenting history, e.g., 'He was in good health until... when he began suffering... the current symptoms commenced...
• Summarize the past medical history succinctly. Only elaborate on aspects that you genuinely believe may be pertinent to the diagnosis or management. •
• Initially, summarize the overall look and vital signs. Present the most critical findings initially, adhering to a methodical approach, such as 'upon examination . . . , during palpation . . . , upon percussion . . . , and by auscultation.'
• Concisely outline further systemic observations. Elaborate on them if they are directly pertinent to the diagnosis or treatment.
• Ultimately, condense and integrate. Attempt to categorize symptoms and indications into clinical patterns that inform the proposed diagnoses or differential diagnosis list.
• Be prepared to discuss which diagnostic or additional evaluation tests may be required.
