Surgery - Prostate Carcinoma
Introduction
a primary prostate gland malignant tumor. 95% of the cases are adenocarcinomas, which vary in their level of differentiation.
Risk Factors
The largest risk factor is age. Afro-Caribbean people are more likely than Caucasian people to present with an aggressive disease at a younger age. Geographic distribution: lower in the Far East and higher in North America and Europe. Gene implicated on chromosome 1 in family history. Dietary factors: Consumption of meat, alcohol, and high fat foods is linked to reduced soy intake.
Epidemiology
The second leading cause of cancer-related mortality in men. 50–70 instances per 100,000 year.
80% of males over 80 years old who have autopsies had microfoci related to malignancy.
History
frequently asymptomatic and found through PSA testing.
Obstruction of the lower urinary tract: nocturia, terminal dribbling, weak stream, hesitation, and frequency.
Metastatic spread: Spinal cord compression or discomfort in the bones as a result of metastases.
Anorexia, weight loss, and malaise are common signs of cancer.
Examination
Asymmetrical hard nodular prostate gland with lack of the midline sulcus was seen during a digital rectal examination.
Investigations
Blood: bone profile, PSA, LFT, U&E, and FBC.
Antigen specific to prostates: Age-related and non-specific values may be higher in cases of prostatitis, benign prostatic hyperplasia, or after catheterization.
Transrectal ultrasonography (TRUS) and needle biopsy: The choice to proceed with TRUS and biopsy is guided by the PSA level and digital rectal examination. Different algorithms are used to make decisions, such as the following: -patients who, regardless of a digital rectal examination, have a PSA more than 10 ng/ml.
-individuals with free PSA <30% and a PSA of 4–10 ng/ml.
-individuals whose digital rectal examination revealed a palpable nodule.
Gleason score: Two scores are assigned depending on predominant appearance, with a maximum score of 5 + 5 (10). Grading is based on histology from biopsy.
CT/MRI scan: Evaluates lymph node involvement and the degree of local invasion.
For bone metastases, use an isotope bone scan.
TNM staging scheme:
T1: confined to the prostate (a: one lobe; b: both lobes); T3: extending through capsule; T4: fixed tumor invading adjacent structures other than seminal vesicles; N1: regional lymph nodes involved; M: metastases. T1a: incidental <5% on TURP; T1b: incidental >5% on TURP; T1c: identified on needle biopsy.
Screening: In the United States, PSA values and digital rectal examination are employed. There is not enough evidence to support universal screening.
Management
Multidisciplinary discussion: on the best treatment option based on the patient's wishes, age, and comorbidities, as well as tumor staging.
Active monitoring For people with low and intermediate risks, watchful waiting along with PSA monitoring is usually the best course of action.
For tumors restricted to the gland, a radical prostatectomy may be necessary. Retropubic (for pelvic lymph node sample) or perineal approaches can be used for this. through laparoscopic, robotically assisted, or open surgery techniques.
Medical hormone therapy involves starting with an anti-androgen (cyproterone acetate) and LHRH analogues (goserelin, for example) to prevent a testosterone flare-up. Other treatments include anti-androgens, such as steroidal or nonsteroidal forms like flutamide and bicalutamide. is a neoadjuvant treatment option.
Surgery for androgen ablation: A bilateral orchidectomy can impede the course of the illness.
Chemotherapy: Hormone-refractory diseases may be treated with cetaxel.
Adjuvant radiation may be used in cases where the surgical resection margins are insufficient or where tumors that are limited to the pelvis affect lymph nodes. Moreover, brachytherapy is an option. It has been demonstrated that neoadjuvant hormone treatment works well for big but localized tumors before external beam radiation therapy. For the treatment of neurological issues and bone pain, palliative radiation therapy is an option.
Complications
Spread: Most frequently, blood-borne spread affects bone (particularly the spine), lung, and liver. Local growth occurs into seminal vesicles, the bladder, and the rectum. Lymphatic spread travels to the iliac and para-aortic nodes.
From disease: metastatic illness, hypercalcemia, obstructive hydronephrosis.
Following surgery: urethral stricture, impotence, and incontinence.
bladder and bowel damage from radiation.
Androgen shortage can result in libido loss, gynecomastia, hot flashes, impotence, and osteoporosis through hormone therapy. Anti-androgen treatment resistance due to tumour hormone escape.
Prognosis
Radical therapy yields a 10-year survival of more than 80%; untreated patients had an 80% 5-year survival.
The median survival time for metastatic illness is 18–24 months.

Surgery - Renal Carcinoma
Introduction
Malignancy originating from the renal tubular epithelium.
Etiology
Mutations in the oncogene (MET) or tumor suppressor genes (VHL, TSC) are linked to sporadic and hereditary forms.
Von Hippel-Lindau disease, hereditary papillary renal carcinoma, familial renal oncocytoma, and hereditary renal carcinoma are examples of hereditary syndromes.
Risk Factors
Chronic dialysis is used to treat acquired cystic disease of the kidney, obesity, smoking, and tuberous sclerosis.
Epidemiology
Rare (three percent of adult cancer cases). 3:1 male to female. grows with age; in men over 60, 75% of cases occur.
History
90% of the time asymptomatic, accidental discovery made when scanning. the traditional trio of abdominal mass, flank pain, and haematuria (only 10% of patients).
Systemic indications of cancer: Loss of weight, lethargy, and paraneoplastic disorders, such as polycythaemia or hypercalcaemia-related pyrexia, are also present.
Examination
Anaemia, plethora, hypertension, or no symptoms could exist. renal tumor that is palpable.A left-sided varicocoele can result from occlusion of the left testicular vein by a left-sided tumor that extends into the left renal vein. In terms of presentation, one-third had metastases.
Investigations
Urine: Cytology, Dipstick (for haematuria detection).
FBC, U&Es, Ca2+, LFTs (linked to paraneoplastic syndromes such as polycythemia, hypercalcemia, abnormal LFTs in the absence of liver metastases, and Stauffer syndrome), and ESR in 75% of the blood samples.
Imaging: bone and PET scanning for metastases; ultrasound, CT, or MRI scans.
Pathology: Clear cell, chromophilic, chromophobic, oncocytoma, and collecting duct are among the histological forms.
Robson staging : I: tumor inside the renal capsule. II: invades the perinephric fat but not Gerota's fascia . III: Invades local lymph nodes, the IVC, or the renal vein. IV: infiltrates distant metastases or nearby viscera.
Management
Surgery : The usual procedure is a radical nephrectomy, which involves the removal of the ipsilateral adrenal gland, regional lymphadenectomy, Gerota's fascia, and perinephric fat. can be carried out using laparoscopic, thoraco-abdominal, transperitoneal, or flank methods.
Radiation therapy and chemotherapy: Renal Carcinoma is well known for its chemotherapeutic agent resistance, which is mediated by p-glycoprotein, a multidrug resistance protein. With more recent multikinase inhibitors like sunitinib and sorafenib, positive results are achievable. Metastatic lesions may be treated with radiation therapy.
Complications
50% of distant metastases impact the lung, and 33% the bone. Local invasion, such as the blockage of the IVC or the invasion of perinephric fat. Localized bleeding and clot colic. Paraneoplastic Syndrome.
Prognosis
Depending on the tumor's nature and stage. Five-year survival after stage I disease excision is 94%; nodal spread accounts for 18–30% of the survival, whereas distant metastases account for 0–20%.

Surgery - Testicular Cancer
Definition
cancer that starts in the testes.
Risk Factors
Risk of ectopic testis or testicular maldescent increased 40 times. Other factors include exposure to maternal oestrogen, family history, mumps, and contralateral testicular tumor. KIT gene mutations and chromosome 12 amplifications and deletions are among the genetic alterations discovered.
Epidemiology
Less prevalent, accounting for 1% of cancer cases in men, but more common in those aged 18 to 35, with a trimodal peak incidence in infancy, 25 to 40 years, and 60 years. Caucasians are more at risk than people of Asian or African descent.
History
A lump found in the testicles. Back pain from para-aortic lymphadenopathy, dyspnea, coughing, or hemoptysis from lung metastases are uncommon causes of back pain.
Examination
Hard testicular tumor that is painless; a secondary hydrocoele may be present. Lymphadenopathy (para-aortic, supraclavicular, etc.). Pleural effusion symptoms. Gynecomastia (caused by the production of HCG).
Pathogenesis
Seminomas (40 percent, peak in 30–40 years) and nonseminomatous germ-cell tumors (60 percent, peak in 20–30 years) are the two types of germ cell tumors. Embyronal cell carcinoma, choriocarcinoma, yolk sac tumors, and teratomas are examples of seminomas. Sertoli and Leydig cell tumors, as well as non-Hodgkin's lymphoma, are less common non-germ cell tumors. Seminomas are solid, light-colored, and well confined. Teratomas have a cystic appearance with parts that are necrotic and hemorrhagic.
Micro: Seminomas are made up of sheets of homogeneous, densely packed cells that can range from anaplastic to well-differentiated spermatocytes. Teratomas are categorized according to the relative proportions and may comprise elements of embryonal and trophoblastic cell types with varied levels of development, as well as tissue from the yolk sac.
Investigations
Blood: FBC, Tumor Markers, U&Es, LFTs LDH, a-fetoprotein, and b-HCG.
Pee: Pregnancy test: If the tumor generates b-HCG, the test is positive.
Ultrasound of the testicles: To see the main tumor.
CT scan for staging (abdomen, chest, and brain if disease is widespread). MRI for unclear lesions or FDG-PET for any remaining seminoma masses.
Either Royal Marsden Hospital staging or TNM staging is employed.
I - Excluded from testes.
II: Lymphadenopathy of the abdomen; A: <2 cm, B: 2–5 cm, C: >5 cm.
III: Nodal involvement above diaphragm; A, B, and C as mentioned previously.
Extralymphatic metastases (Part IV).
Management
depends on the tumor's prognostic classification, stage, and histology. Before receiving chemotherapy or radiation therapy, patients should be given sperm banking.
Seminoma: Excision of the afflicted testis with radical inguinal orchidectomy.
Stage I: Adjuvant radiation (seminomas are very radiosensitive), chemotherapy (one carboplatin cycle), or observation are the available options.
Radiotherapy, chemotherapy, or both in stages IIA and IIB.
Multiagent chemotherapy (e.g., BEP; bleomycin, etoposide, cisplatin) for patients in Stage IIC and above.
Radical inguinal orchidectomy in nonseminomatous GCT.
Microscopic metastases to retroperitoneal lymph nodes will occur in 30% of cases in stage I. Options include primary retroperitoneal lymph node dissection (RPLND), chemotherapy, and surveillance.
Stage II–IV: RPLND and/or multiagent platinum-based chemotherapy (seedling retroperitoneal lymph node masses that are less than 1 cm in size should be excised since they might harbor residual tumor material).
Complications
Of the illness: Metastases leading to neurological or pulmonary issues.
Treatment: Surgery for hemorrhage, nerve damage, and wound infection.
Chemotherapy side effects include bone marrow depression, nausea, and vomiting. While platinum compounds are neuro- and nephrotoxic, bleomycin can result in rashes, pneumonitis, or fibrosis. heart illness and subsequent cancers with long-term survival.
Blood-borne spread to the lungs, brain, bone, and liver; local spread to the tunica vaginalis and down the spermatic cord; lymphatic spread to the para-aortic nodes, then to the mediastinal and supraclavicular nodes.
Prognosis
Good, with 90%–100% cure rates for early-stage illnesses. Seminomas have a high rate of cure.

Surgery - Testicular Torsion
Definition
An urgent surgical procedure is required to treat spermatic cord twisting or torsion, which first obstructs the testis's venous outflow and, if left untreated, progresses to artery occlusion and testicular infarction.
Etiology
Intravaginal (most common type): The testis might twist inside the vaginalis due to a large investment of the tunica vaginalis around the spermatic cord.
Extravaginal (found in newborns): A condition in which the spermatic cord twists along a vertical axis, causing the entire testes and tunica vaginalis to twist (since the gubernaculum is not fully fixed to the scrotal wall, allowing for unrestricted rotation).
Risk Factors
Bell clapper testes, or imperfectly descending testes, have a large investment in the tunica vaginalis, and the epididymal mesentery is lengthy.
Epidemiology
Incidence each year: 1 in 4000. The most frequent cause of acute scrotal pain in children aged 10 to 18 is intravaginal. exceptionally uncommon in newborns (extravaginal torsion).
H HISTORY
strong hemiscrotal pain that develops suddenly and may be accompanied by nausea, vomiting, and stomach pain. The patient may have discomfort upon awakening from sleep or may have previously experienced a similar pain that resolved on its own.
Examination
The affected side may have an erythematous, swollen scrotum, a palpably thicker cord, and an anteriorly positioned epididymis. The testis may be extremely tender, positioned higher than the contralateral side, and horizontal. There might not be a cremasteric response.
Differential diagnosis: Appendix testes, appendix epididymis, and hydatid of Morgagni are examples of testicular appendix torsion. A lesion that is apparent via transillumination (blue dot sign) might exist.
Epididymo-orchitis with inguinal hernia in prison.
Pathogenesis
If the blood supply is not restored by detorsion, twisting causes compression of the veins of the pampiniform plexus from the testis and venous congestion, which leads to progressive ischaemia and infarction.
Investigational studies
Until proven otherwise, a young boy or adolescent with a very sensitive and swollen testis should be treated as if they have torsion, necessitating immediate investigation.
Testicular Doppler or Duplex Imaging: Surgery shouldn't be postponed, but it may be done.
In cases of torsion, arterial inflow may be decreased; in cases of epididymo-orchitis, it may cease.
Management
Surgical: Scrotal exploration should ideally be done within six hours of the onset of symptoms.
Counseling on bilateral orchidopexy and orchidectomy should be a part of consent. A transverse or midline raphe incision is done through the muscle of the dartos. The testis is delivered and examined after the tunica vaginalis is opened. The testis is untwisted, allowed to reperfuse, and then covered for a short while with a warm swab soaked in saline.
Bilateral orchidopexy is performed next. In order to stop recurrence, the testis was traditionally fixed in three places to the scrotal tissues using nonabsorbable sutures. An orchidectomy is carried out if it is discovered that the testis is necrotic.
Complications
Atrophy and infarction of the testicles if treatment is delayed. If left untreated, the testes could become infected or worsen fertility by encouraging the production of antibodies against sperm.
hemorrhage and infection following surgery.
Prognosis
A testicular torsion may only last 4-6 hours from the time pain starts.Most instances can be saved with quick investigation.

Incidence each year: 1 in 4000. The most frequent cause of acute scrotal pain in children aged 10 to 18 is intravaginal. exceptionally uncommon in newborns (extravaginal torsion).
H HISTORY
strong hemiscrotal pain that develops suddenly and may be accompanied by nausea, vomiting, and stomach pain. The patient may have discomfort upon awakening from sleep or may have previously experienced a similar pain that resolved on its own.
Examination
The affected side may have an erythematous, swollen scrotum, a palpably thicker cord, and an anteriorly positioned epididymis. The testis may be extremely tender, positioned higher than the contralateral side, and horizontal. There might not be a cremasteric response.
Differential diagnosis: Appendix testes, appendix epididymis, and hydatid of Morgagni are examples of testicular appendix torsion. A lesion that is apparent via transillumination (blue dot sign) might exist.
Epididymo-orchitis with inguinal hernia in prison.
Pathogenesis
If the blood supply is not restored by detorsion, twisting causes compression of the veins of the pampiniform plexus from the testis and venous congestion, which leads to progressive ischaemia and infarction.
Investigational studies
Until proven otherwise, a young boy or adolescent with a very sensitive and swollen testis should be treated as if they have torsion, necessitating immediate investigation.
Testicular Doppler or Duplex Imaging: Surgery shouldn't be postponed, but it may be done.
In cases of torsion, arterial inflow may be decreased; in cases of epididymo-orchitis, it may cease.
Management
Surgical: Scrotal exploration should ideally be done within six hours of the onset of symptoms.
Counseling on bilateral orchidopexy and orchidectomy should be a part of consent. A transverse or midline raphe incision is done through the muscle of the dartos. The testis is delivered and examined after the tunica vaginalis is opened. The testis is untwisted, allowed to reperfuse, and then covered for a short while with a warm swab soaked in saline.
Bilateral orchidopexy is performed next. In order to stop recurrence, the testis was traditionally fixed in three places to the scrotal tissues using nonabsorbable sutures. An orchidectomy is carried out if it is discovered that the testis is necrotic.
Complications
Atrophy and infarction of the testicles if treatment is delayed. If left untreated, the testes could become infected or worsen fertility by encouraging the production of antibodies against sperm.
hemorrhage and infection following surgery.
Prognosis
A testicular torsion may only last 4-6 hours from the time pain starts.Most instances can be saved with quick investigation.

Surgery - Urinary Tract Calculi
Definition
stone buildup in the urinary system. also referred to as renallithiasis.
Etiology
Urine becomes supersaturated with chemicals that form stones, causing crystallization around a focal point and creating calculi.
Calculus type and description
80% calcium phosphate and calcium oxalate.
Can be dotted, mulberry, or spiculated varieties
10%–20% of magnesium ammonium phosphate (struvite).
connected to microorganisms splitting urea, such as Proteus, Pseudomonas, and Klebsiella. may cause kidney stones known as staghorn stones.
5% are urate,occurs in urine that is acidic and is linked to cell lysis, small bowel illness, and gout.
Cystine
Rare (<1%). forms in the uncommon autosomal recessive metabolic disease cystinuria
Etiology
Hypercalciuria, hyperuricaemia, hypercystinuria, and hyperoxaluria are metabolic conditions.
Infection: Bacteria splitting urea, causing hyperuricemia.
Urinary stasis is caused by anatomic factors such as the horseshoe kidney and caliceal diverticulae.
Renal tubular acidosis type I, medullary sponge kidney, and adult polycystic kidney disease are examples of kidney diseases.
Medicines: indinavir, for instance.
Epidemiology
Prevalence: 2-3%, common. Risk over lifetime is 5–15%. 15% of cases are bilateral. A 3:1 male to female ratio.
History
be absent of symptoms. Severe discomfort extending from the loins to the groins caused by ureteric stones may be accompanied by nausea and vomiting.
urgency, regularity, infections, or retention of the urine.
Microscopic or frank haematuria (may not be present in up to 10% of cases).
Examination
Tenderness in the lower abdomen or loins. The most crucial differential diagnosis for elderly people to take into account is a leaking AAA. indications of systemic sepsis in the event of infection and blockage.
Investigational studies
Blood: FBC, PO4 3-, urate, Ca2+, and U&E (to evaluate renal function).
Urine: 24-hour urine collection, dipstick, microscopy, culture, and sensitivity.
CT scan (KUB film): Ninety percent of stones appear on a plain radiograph because they are radio-opaque.
Intravenous urogram: At first, a delayed dense nephrogram is seen with an obstructed ureteric stone; later images reveal a dilated pelvicaliceal system and a standing column of contrast down to the stone's location.
Non-contrast CT: Higher radiation dose, most sensitive for detecting stones.
Ultrasound: Not sensitive for tiny stones, but can demonstrate hydronephrosis or ureteral dilatation due to obstructive uropathy. used in patients who shouldn't be exposed to radiation or contrast, such as those who are pregnant.
Isotope renography: Evaluation of renal function in complex stone disease (e.g., using DTPA or DMSA).
Management
Analgesia and IV or oral hydration are the treatments for acute presentation. collecting urine to get the calculations that passed analysis. Ideal for stones that don't obstruct; most stones that are less than 5 mm can pass. Stones can be passed by ureteric relaxation with the aid of alpha-blockers, such as alfusozin. A kidney that has become infected and obstructed needs to be treated immediately. This can be done with a ureteroscopy and stent or a radiologically guided percutaneous nephrostomy along with supportive care and antibiotics.
Calculus removal: Suggested in cases of pyrexia, persistent discomfort, or blocking stones.
Ureteroscopy: A rigid or flexible ureteroscope is inserted into the bladder and up the ureter to visualize the stone, which can then be removed with a grasper, basket, or laser or ultrasonography. Urine drainage should be ensured by the placement of a JJ stent in the event that the stone is affected and cannot be removed.
Outside-the-body shock-wave lithotripsy: Non-intrusive. Calculus is subjected to an electromagnetic or piezoelectric shock wave in order to split it up into smaller pieces that can naturally pass. Fit for stones smaller than 2 cm, provided that there is no drainage blockage.
Nephrolithotomy via percutaneous means: Used for large, complicated stones, such as staghorn calculi. A nephroscope is inserted after the nephrostomy path is created, enabling the dissolution and removal of stones. During the first two days following surgery, a nephrostomy tube is left in place, and a nephrostogram is done to make sure the stone is gone and to verify ureteric drainage.
Seldom done open nephro-, pyelo-, or ureterolithotomies (for complicated cases).
Nephrectomy: in case of a non-functioning kidney, may be necessary.
Management of the cause: Based on the underlying reason, such as parathyroidectomy, dietary calcium or oxalate limitation, or allopurinol. Urate and cystine stones can be broken up by urine alkalinization with oral potassium citrate.
Suggestion: Promote a substantial intake of oral fluids.
Complications
Of stones: Septicemia, urinary retention, and infections, including pyelonephritis.
False route, perforation in ureteroscopy.
Pain, haematuria, and steinstrasse—a ureteric blockage brought on by a column of broken stone—are symptoms of lithotripsy.
Prognosis
Excellent, yet there is a 50% chance of recurrence during a five-year period, and infection may cause irreparable kidney scarring.

Surgery - Abdominal Aortic Aneurysm
Defintion
a deviation of >3 cm, or 50% over the normal diameter, in the abdominal aorta's localized dilatation. mostly affects the infrarenal aorta (95%) and the iliac arteries (30%).
Etiology
Degeneration of collagen and elastin in the artery wall is most likely the cause. frequently connected to atherosclerosis. Other conditions include connective tissue illnesses including Marfan's syndrome and Ehlers-Danlos type IV, traumatic injuries, infectious (mycotic), inflammatory (chronic inflammatory infiltration in the artery wall), and arthritis.
Risk Factors
Hypertension, smoking, coronary artery disease, popliteal artery aneurysms, smoking, and family history (10-fold "risk if first-degree relative affected). According to Laplace's law (tension as a radius, pressure), the diameter affects the likelihood of rupture. The risk for AAAs is 3.3% annually for 5–5.9 cm, 9.4% annually for 6–6.9 cm, and 24% annually for 7–7.9 cm.
Epidemiology
15% of people over 80 years old and 5% of people over 60 will have a AAA. Four to six times more common in men; in England and Wales, there are 6000 deaths annually.
History
Often asymptomatic, it can be discovered by accident during testing, imaging, or inspection.
Symptoms: The most typical presentation is collapse or epigastric or back pain due to the rupture of an unidentified AAA. Most patients who are admitted to the hospital have a retroperitoneal leak.
Perhaps mistaken as diverticulitis, muscular back pain, or renal colic. Because of distal embolization or vertebral erosion, intact aneurysms might result in lower limb ischaemia or back pain. Occasionally, exhibit severe gastrointestinal bleeding from erosion into the duodenum or high-output heart failure from an aortocaval fistula.
Examination
One feels a pulsating mass over the umbilicus. If there is leakage or rupture, pallor in the abdomen and back, tachycardia, hypotension, hypovolaemic shock, sporadic bruises on the flanks, and indications of emboli to the feet.
Investigational studies
Sharp presentation Bloods: coagulation, ECG, CXR, U&Es, FBC, and urgent blood cross-matching.
Bedside ultrasonography: To verify the aneurysm's size and presence.
In stable or diagnostic uncertainty: If stable or diagnostic doubt.
CT scan: Not if unstable; instead, proceed directly to the operating room or endovascular suite for repair.
Numerous facilities provide emergency EVAR.
Examining: Research, like the Multicentre Aneurysm Screening Study (MASS), has demonstrated that screening males 65 years of age and older with ultrasound reduces the mortality associated with aneurysms, is economical, and will, over the course of 20 years, minimize the need for emergency surgery by more than two-thirds.
To determine the morphology of an aneurysm before therapy, use CT or MR angiography.
Conservative management of asymptomatic aneurysms (less than 5.5 cm) involves regular follow-up ultrasound scanning (every 3.4 cm annually, or every 6 months if enlargement exceeds 10% annually), as well as managing cardiovascular risk factors. This was shown by the UK Small Aneurysm Study.
Radiological: There are ongoing research comparing endovascular treatment with stent placement (EVAR) against open repairs. EVAR is becoming more common. Between 40 and 60 percent of AAAs are acceptable, meaning they have a neck and landing sites that are ideal for the endograft. When EVAR and open surgery were compared in individuals deemed surgically capable, EVAR1 had a 3% advantage in aneurysm-related survival after 4 years. When EVAR2 was applied to unfit patients, it did not find any differences in all-cause mortality between EVAR and no intervention.
Surgical: Using tube or bifurcation grafts (see to Procedures) is recommended for: asymptomatic aneurysms larger than 5.5 cm in diameter; symptomatic or quickly increasing aneurysms; emergency treatment (e.g., suspected leaking or ruptured aneurysm).
Complications
The most common include rupture, distal embolus, abrupt total thrombosis, gram-negative or staphylococcal infection, persistent consumptive coagulopathy, ischaemia of the gut, aortic-intestinal fistula, and arteriovenous fistula resulting from aneurysm eroding into the inferior venous catheter.
following surgery: bleeding, thrombosis, embolism, colonic ischaemia, renal failure, problems related to the heart and lungs, and death.
Of EVAR: As mentioned before; also, migration, endoleak, kinking/distortion, fracture of the stent, renal infarction, and limb/pelvic ischaemia.
Prognosis
Only roughly 50% of patients with a ruptured AAA survive once they get at the hospital, accounting for the remaining 80% of deaths.
Mortality from elective open surgery is less than 5% in specialized centers. EVAR has a 2% death rate, however re-intervention rates are greater and observation is necessary.

Surgery - Aortic Dissection
Introduction
A disorder where blood can enter the aorta wall through a rupture in the aortic intima, splitting the inner and outer tunica media and forming a false lumen.
Etiology
The predisposing event is degenerative alterations in the aortic media's smooth muscle.
Aortic atherosclerosis, hypertension, connective tissue diseases (SLE, Marfan's, Ehlers-Danlos), congenital cardiac abnormalities (aortic coarctation, for example), aortitis (Takayasu's aortitis, tertiary syphilis), iatrogenic (during angiography or angioplasty, for example), trauma, and crack cocaine are common causes and predisposing factors.
Aortic Dissection is divided by Stanford categorization into:
Type A: Aorta tears that ascend (most common); Type B: Aorta tears that descend, extending away from the left subclavian artery.
False aneurysm expansion can block the renal, celiac, subclavian, or carotid arteries.
Epidemiology
most typical in the age range of 40 to 60. Men outnumber women.
History
An MI may seem like an abrupt core tearing pain that radiates to the back.
The aorta and its branches may become occluded as a result of aortic dissection.
Blackout, dysphasia, and hemiparesis due to carotid blockage.
Chest pain due to coronary artery blockage (angina or MI).
Ataxia and loss of consciousness due to subclavian blockage.
Paraplegia: anterior spinal artery.
Severe abdominal pain due to a celiac blockage (ischaemic bowel).
Renal failure and anuria due to renal artery blockage.
Examination
A murmur on the back that descends to the belly below the left scapula.
Blood pressure: Wide pulse pressure, hypertension (BP difference between arms of >20 mmHg). In case hypotension indicates tamponade, make sure to look for pulsus paradoxus.
An insufficient aorta Early diastolic murmur across the aortic region, collapsing pulse.
Arm pulses that aren't equal.
Investigational studies
Blood: coagulation, U&E (renal function), FBC, and cross-match.
CXR: Localized aortic arch bulging and widened mediastinum.
ECG: Usually normal. indicators of inferior MI or left ventricular hypertrophy if the right coronary artery's ostia is compromised by dissection.
False lumen of dissection visible in CT thorax abdomen.
Trans-oesophageal echocardiography is quite specific.
Vascular angiography and cardiac catheterization.
Management
Acute: In the event that resuscitation is suspected, an immediate CT scan should be carried out. Restart the heart and keep an eye on your blood pressure, pulse, and urine catheter. Idealized for ITU management.
Surgery is used to treat type A dissection. A surgical emergency due to the possibility of cardiac tamponade. A tube graft is used to repair the damaged aorta. Replaced aortic valves are another option.
Treatment options for type B dissection include medication, surgery, and endovascular stenting. take IV nitroprusside and/or IV labetalol to control blood pressure and stop additional dissection (take a calcium channel blocker if b-blockers are contraindicated). Patients with end-organ ischemia, aortic enlargement, intractable or recurrent pain, or dissection advancement may benefit from surgery. Some centers offer endovascular repair, a more recent procedure that uses endovascular stents (ADSORB trial results awaited).
Complications
cardiac tamponade, syncope, cerebrovascular, renal, mesenteric, or spinal ischaemia; aortic rupture.
Prognosis
30% in 24 hours and 75% at 2 weeks of untreated mortality.
5–10% operational mortality. 10% more suffer from neurological aftereffects.
Type B has a better prognosis than type A.

Surgery - Penile Carcinoma
Introduction
The most frequent type of penile cancer is squamous cell carcinoma.
Etiology
The primary risk factor is :
-Human papillomavirus Condyloma acuminata & Balanitis, a persistent foreskin infection, and smoking
- Balanitis xerotica obliterans (a type of lichen sclerosus, a chronic inflammatory illness of the glans or foreskin);
-Bowen's disease (intraepithelial carcinoma of the penile shaft);
-Erythroplasia of Queyrat (a type of cancer in situ of the glans skin).
Epidemiology
In developed nations, uncommon (<0.5% of adult male cancer cases). more prevalent in South America and Africa. Most frequently observed in older men (aged 50–70).
History
The patient may describe a gradually growing lesion that is frequently painless, delaying seeking medical assistance. There can be discharge or bleeding in addition.
Examination
Most frequently appears on the inner surface of the foreskin or glans penis. It starts off as a painless red lesion and progresses to an exophytic or nodular growth or ulcer. A secondary infection that frequently results in a discharge or disagreeable odor is also common. Up to 50% of cases had inguinal lymphadenopathy, which is frequently brought on by an infection or inflammation, but only 30–60% of these cases show indications of tumor dissemination.
Pathogenesis
These are G1–G3 histological grades of squamous cell carcinomas. Jackson categorization of Stage I: Limited to the foreskin or glans. Stage II: The corpora's involvement.
Stage III: Inguinal nodes are reached. Remote metastases are in Stage IV. TNM staging is also included. Giant condyloma of Buschke-Lowenstein is a variation that exhibits a distinctive strongly defined deep boundary and spreads locally.
Investigations
Punch or excisional biopsy is used to make the diagnosis (condylomata acuminata, syphilitic chancre, or infrequently chancroid are the differential diagnoses).
Imaging: looking for signs of spread using CT or MRI scanning. biopsy of sentinal lymph nodes.
Management
Localized disease: 5-fluorouracil cream, laser photocoagulation, or cryosurgery for glans or Bowens disease on the shaft (carcinoma in situ).
Operative: Wide local excision, Mohs microsurgery, stage I and II, and partial penectomy with 2 cm proximal disease-free margins are recommended for the early stage. Complete penectomy combined with the creation of a perineal urethrostomy in more complex instances.
If impalpable, occult metastases occur in 20–25% of inguinal nodes. Metastases may not be the cause of palpable nodes. If a scanning results in suspicion, bilateral lymphadenectomy. More recently, limited inguinal node dissection superficial to the fascia lata or sentinel node biopsy.
Radiotherapy: As part of a combination modality therapy for the palliation of advanced-stage cancer, or locally for early-stage disease if the tumor is not big, invasive, or involves the urethra.
Chemotherapy: Usually limited to cases when the cancer has spread systemically; medications like cisplatin and irinotecan be utilized.
Prevention: The number of newborns who need to be circumcised to prevent one case of cancer is reduced by 909. Maintaining proper cleanliness and receiving the right care for Queyrat erythroplasia.
Complications
Following surgery: urethral stricture, wound disintegration, infection, and lymphoedema. Penectomy's psychological side effects.
Prognosis
frequently arrive late out of shame or neglect. The five-year survival rate for in situ disease is >90%; for invasive disease that has not progressed to lymph nodes, it is 80%; for nodal involvement, it is roughly 50%; and for distant metastases, it is less than 20%.

A secondary infection that frequently results in a discharge or disagreeable odor is also common. Up to 50% of cases had inguinal lymphadenopathy, which is frequently brought on by an infection or inflammation, but only 30–60% of these cases show indications of tumor dissemination.
Pathogenesis
These are G1–G3 histological grades of squamous cell carcinomas. Jackson categorization of Stage I: Limited to the foreskin or glans. Stage II: The corpora's involvement.
Stage III: Inguinal nodes are reached. Remote metastases are in Stage IV. TNM staging is also included. Giant condyloma of Buschke-Lowenstein is a variation that exhibits a distinctive strongly defined deep boundary and spreads locally.
Investigations
Punch or excisional biopsy is used to make the diagnosis (condylomata acuminata, syphilitic chancre, or infrequently chancroid are the differential diagnoses).
Imaging: looking for signs of spread using CT or MRI scanning. biopsy of sentinal lymph nodes.
Management
Localized disease: 5-fluorouracil cream, laser photocoagulation, or cryosurgery for glans or Bowens disease on the shaft (carcinoma in situ).
Operative: Wide local excision, Mohs microsurgery, stage I and II, and partial penectomy with 2 cm proximal disease-free margins are recommended for the early stage. Complete penectomy combined with the creation of a perineal urethrostomy in more complex instances.
If impalpable, occult metastases occur in 20–25% of inguinal nodes. Metastases may not be the cause of palpable nodes. If a scanning results in suspicion, bilateral lymphadenectomy. More recently, limited inguinal node dissection superficial to the fascia lata or sentinel node biopsy.
Radiotherapy: As part of a combination modality therapy for the palliation of advanced-stage cancer, or locally for early-stage disease if the tumor is not big, invasive, or involves the urethra.
Chemotherapy: Usually limited to cases when the cancer has spread systemically; medications like cisplatin and irinotecan be utilized.
Prevention: The number of newborns who need to be circumcised to prevent one case of cancer is reduced by 909. Maintaining proper cleanliness and receiving the right care for Queyrat erythroplasia.
Complications
Following surgery: urethral stricture, wound disintegration, infection, and lymphoedema. Penectomy's psychological side effects.
Prognosis
frequently arrive late out of shame or neglect. The five-year survival rate for in situ disease is >90%; for invasive disease that has not progressed to lymph nodes, it is 80%; for nodal involvement, it is roughly 50%; and for distant metastases, it is less than 20%.

Surgery - Upper Gastrointestinal Hemorrhage
Introduction
bleeding that originates from the upper portion of the gastrointestinal tract, or close to the Treitz ligament.
Etiology
Acute or chronic conditions include the following: 50% of instances of stomach and duodenal ulcers; acute erosive gastritis; oesophagitis or duodenitis; oesophageal or gastric varices; Mallory-Weiss tear; gastric angiogenesis or Dieulafoy's malformation; tumors or, less frequently, haemobilia; aorto-enteric fistula; or amyloidosis.
Risk Factors
NSAIDs, steroids, and Helicobacter pylori are risk factors for the onset or aggravation of erosions and ulcers. Stress ulcers 2 in burn patients and Cushing's ulcer in head injuries are related to shock and decreased splanchnic perfusion. Gastric erosions can be triggered by binges of alcohol.
Vomiting frequently raises the danger of a Mallory-Weiss tear.
Epidemiology
An yearly average of 50–80–100,000 upper gastrointestinal bleeding cases occur in the United Kingdom.
more typical among older people.
History
Cause-related history (e.g., drunkenness, NSAID use, vomiting).
Acute: Haematemesis of freshly drawn blood or dark, partially digested blood (referred to as "coffee grounds"), melaena (loose, black, tarry, foul feces), which may indicate a bleeding episode larger than 50 mL or, in the event of fast bleeding, frank PR blood loss.
Chronic: positive faecal occult blood test, iron deficiency anemia.
Examination
indicators of chronic iron deficiency anemia or other indicators, such as spider naevi, palmar erythema, bruising, jaundice or ascites in liver illness, orofacial telangiectasia in Osler-Weber-Rendu syndrome.
signs of hypovolemia, tachycardia, hypotension, shock, and impaired mental status.
Investigations
Blood: LFT, crossmatch, clotting, U&Es, and FBC.
Oesophagogastroduodenoscopy (OGD): Allows for treatment by locating the bleeding site.
A visible vessel, an adhering clot, or ongoing bleeding are indicators of a recent hemorrhage.
Massive bleeding from the gastroduodenal artery can result from posterior duodenal ulcers.
Mesenteric angiography: Identifies the bleeding source, however the flow rate needs to be between 1 and 1.5 mL/minute in order to facilitate embolization therapy.
Management
Resuscitation techniques include the use of blood products and fluids, appropriate IV access, the ABCs, and the treatment of coagulopathy.
Medical: H2-antagonists or PPIs to lower the production of acid. elimination of H. pylori once a duodenal ulcer becomes stable. Vasopressin or somatostatin analogues, such as octreotide, are helpful in treating variceal hemorrhage because they lower portal pressure and splanchnic blood flow.
An oesophageal varices can be mechanically compressed by inserting a Sengstaken–Blakemore tube.
Endoscopic: Upper GI endoscopy for final upper gastrointestinal bleeding diagnosis and treatment.
For bleeding ulcers, treatments include photocoagulation, diathermy, adrenaline injection, or a combination of these. Injection sclerotherapy or band ligation are used to treat varices.
Radiological: In patients who are not candidates for surgery, embolishing the bleeding location might be feasible. In cases of uncontrollable variceal hemorrhage, transjugular intrahepatic portocaval shunts can be used instead of endoscopic procedures.
Surgical: In cases of potentially fatal bleeding, endoscopic treatment failure (10–12%), or concurrent surgical needs (such as perforations). The process is site- and cause-specific; for example, if a duodenal ulcer is under-running, a partial gastrectomy may be necessary for stomach ulcers.
Complications
anemia, shock from low blood volume, and collapse.
Prognosis
Depending on the etiology, early management and aggressive resuscitation improve outcomes for serious gastrointestinal bleeding. Patients who are at risk of a negative outcome are identified by the Rockall score (see table below).
Higher mortality in coagulopathy, cardiovascular disease, older age groups (14%) and those presenting with hemorrhagic shock (30%). Up to 20% of individuals may experience recurrent bleeding following endoscopic therapy.
