Surgery - Pyloric Stenosis
Introduction
pylorus hypertrophy in newborns, which obstructs the stomach's outflow.
Etiology
Uncertain, but maybe connected to anomalies in the smooth muscle, interstitial cells of Cajal, or pyloric innervation that cause the pyloric smooth muscle to enlarge and become hyperplasia.
linked to 2% of cases of jaundice because to a hepatic glucuronyl transferase activity deficiency that goes away following surgery.
Epidemiology
3 cases per 1000 annually; less common in Asian and African populations. The male to female ratio is 4:1; it usually manifests in the first two to twelve weeks of life, however premature babies may experience it later.
H HISTORY
The baby vomits milk violently, like a "projectile." This vomiting is not bilious, but if it persists, it could stain the baby's oesophagus with blood. The infant appears hungry and healthy at first, but over time, it becomes dehydrated and lethargic.
Examination
In addition to showing symptoms of dehydration (sunken fontanelles, dry mucous membranes, low skin turgor, and 5–15% body weight), the baby may appear healthy or underweight. Gastric peristaltic waves from the left to the right upper quadrant can be seen on an abdominal examination. A hard, olive-sized lump in the epigastrium is known as a pyloric "tumour" when the pylorus becomes hypertrophied.
Investigational studies
Blood: U&Es, capillary gases, and metabolic alkalosis with decreased K+ and Cl-—the latter indicating the degree of dehydration—are used to assess metabolic disturbance.
Imaging: An ultrasound shows that the pyloric canal has constricted (wall thickness > 4 mm, overall diameter > 10 mm, length > 18 mm) and the pylorus muscle has thickened.
Management
General: IV fluids are used to correct biochemical imbalances and rehydrate patients before to any operation; otherwise, there is a danger of apnea following anesthesia due to a loss of respiratory drive brought on by lower H+ from alkalosis and reduced CO2 from ventilation. To stop the stomach contents from aspirating, an NG tube is placed.
Operative: The final treatment, known as a Ramstedt's pyloromyotomy, is often performed in a specialized pediatric surgical department. can be carried out laparoscopically or through open incisions in the stomach or circumumbilical region. After identifying the pylorus and cutting the serosa with a knife or diathermy, the circular muscle splits along the anterior wall and descends to the mucosa. To make sure the mucosa has not been punctured, the stomach is next inflated with air; if this is the case, the defect needs to be sutured and an omental patch should be placed over the mucosa.
Complications
hunger, thirst, gastritis and oesophagitis, hypochloraemia, hypokalaemia, metabolic alkalosis, aspiration, and respiratory distress syndrome.
surgical site infections, incisional hernias, and mucosal perforations. 10% of patients experience chronic vomiting after surgery, however this normally goes away (may be linked to reflux illness).
Prognosis
Usually very good. In surgical patients, morbidity is less than 3% and mortality is less than 0.5%.

Surgery - Gastric Volvulus
Indications
The abnormal rotation of all or part of the stomach above 180 degrees, known as gastric volvulus, can cause blockage. Based on the axis of rotation, they can be categorized as subdiaphragmatic (1/3) or supradiaphragmatic (2 /3, linked to diaphragmatic defects):
Mesenteroaxial: Rotation along an axis perpendicular to its longitudinal axis; Organoaxial: Rotation along a longitudinal axis via the gastroesophageal junction and the stomach.
Combination types are possible.
Etiology
Abnormal laxity of the gastrosplenic, gastroduodenal, gastrohepatic, and gastrophrenic ligaments is referred to as subdiaphragmatic (more prevalent in adults).
Supradiaphragmatic: Paraoesophageal hernia; congenital or acquired anatomical defects of the diaphragm.
Epidemiology
The most prevalent kind is organoaxial; mixed occurrences are uncommon. Children, typically under a year old, account for ten to twenty percent of instances. Seldom seen in adults under 50.
History
Severe epigastric or chest pain, ineffective retching, and rarely hemomatemesis or respiratory difficulty are the emergency symptoms of acute volvulus. Chronic volvulus: in children, feeding difficulties and stunted growth; epigastric pain and fullness after meals.
Examination
discomfort and distention in the upper abdomen.
The trio of Borchardt syndrome is pain, retching, and difficulty passing a nasogastric tube.
Investigations
CXR: If intrathoracic, a gas bubble appears behind the heart.
AXR: A highly enlarged viscus gas shadow.
Acute case diagnosis via barium swallowing or CT scanning.
Management
General: Nasogastric decompression trial and resuscitation. Although it is controversial, endoscopic reduction can be tried as a temporary solution for patients who are at high risk of surgery.
Surgical: Volvulus reduction, either open or laparoscopic. The viability of the stomach is evaluated, and if gangrenous, a partial, subtotal, or total gastrectomy may be necessary.
Anterior gastropexy is done in conjunction with the repair of any related diaphragmatic defect in order to prevent recurrence.
Complications
Vascular compromise include ulceration, bleeding, perforation, and strangling and necrosis.
Prognosis
The high non-operative death rate is typically caused by a delayed diagnosis, particularly in cases of acute presentations. With proper care, mortality is currently less than 16%.

Surgery - Benign Prostatic Hyperplasia
Introduction
The most common cause of lower urinary tract symptoms in adult males is nodular hyperplasia of the prostate gland's periurethral (transitional) zone, which progresses gradually.
Etiology
Unknown exact cause; linked to age, exposure to testosterone and dihydrotestosterone.
A pseudocapsule of compressed peripheral zone glandular tissue envelops the epithelial and stromal hyperplasia of the prostate's periurethral transition zone.
Epidemiology
Frequent: West>Far East, Afro-Carribean>Caucasian men are more likely than East men to have histological benign prostate hypherplasia (BPH), which affects 70% of men over the age of 70. Of them, 50% have substantial symptoms.
History
Hesitancy, a weak or irregular stream, terminal dribbling, and incomplete emptying are examples of obstructive signs.
Frequency, urgency, urge incontinence, and nocturia are indicative of irritation/storage.
An assessment tool for symptoms and therapy response is the International Prostate Symptom Score.
Acute retention is characterized by an abrupt inability to urinate and excruciating pain.
Chronic retention: Frequency and painless passage of tiny amounts of pee, particularly during night.
Examination
The prostate is frequently enlarged during digital rectal examination; however, there is frequently little relationship between the size and symptoms, and if the prostate is noduled, prostate cancer should be feared.
Acute retention manifests as enlarged, palpably felt bladder and suprapubic discomfort.
Chronic retention: A large, distended bladder that is painless (residual volumes greater than 1 L), possibly accompanied by indications of renal failure.
Investigational studies
Bloods: PSA, U&Es for kidney function.
Urine: For sensitivity, culture, and microscopy.
Imaging: Renal tract ultrasound imaging to look for upper urinary tract dilatation. Pre- and post-voiding volumes are measured using bladder scanning.
Transrectal ultrasound: To guide biopsies and quantify prostate size.
Histopathology: Prostate periurethal transition zone epithelial and stromal hyperplasia is encircled by a pseudocapsule made of compressed peripheral zone glandular tissue.
Flexible cystoscopy: To see changes in the bladder, such as trabeculation, and the bladder outlet.
Others: Flowmetry investigations of urinary flow.
Management
Depending on how severe the symptoms are and whether there are any consequences.
Urinary catheterization in cases of acute retention is an emergency.
Conservative: If symptoms are moderate, monitoring them with the IPSS questionnaire while exercising caution may be necessary.
Health: Alfuzosin and tamsulosin are examples of selective a-blockers that relax the smooth muscle of the prostate capsule and the internal (bladder neck) sphincter. 5 a-reductase inhibitors, such as finasteride, work by preventing the conversion of testosterone to dihydrotestosterone; they can lower prostate growth by 20%, but results may not be seen right away.
Surgery: Prostate excision from within the urethra is known as transurethral resection of the prostate (TURP), and it can be accomplished using a number of techniques, including laser and electrocautery.
Usually reserved for very large glands (>60 g), open prostatectomy (retropubic or suprapubic approaches) can be carried out via open surgery, laparoscopic, or robot-assisted surgery.
Complications
urinary stasis, bladder stones or diverticulae, acute or chronic urine retention, recurrent urinary infections, obstructive renal failure, and post-obstructive diuresis.
From TURP, the following conditions are common: retrograde ejaculation; hemorrhage (primary, reactionary, or secondary 2–10%); clot retention; incontinence; TUR syndrome (seizures or cardiovascular collapse caused by hypervolaemia and hyponatraemia due to absorption of glycine irrigation fluid); erectile dysfunction; late: urethral stricture.
Prognosis
Medical treatments can help with mild symptoms, but surgical surgery typically provides great relief for patients with more severe problems.

Surgery - Bladder Cancer
Introduction
Urinary bladder epithelial cancer.
The majority are bladder epithelium-changing transitional cell carcinomas.
Others include adenocarcinomas that originate in the urachal remnant or squamous cell carcinomas linked to long-term inflammation (such as inschistosomiasis). Less common are leiomyosarcomas, carcinosarcomas, and small cell carcinomas (neuroendocrine).
Etiology
A number of genetic anomalies are linked to superficial tumors, such as chromosome 9 mutations in p15 and p16. Mutations in p53, p21, ras, c-myc, and c-jun are among the others.
Risk Factors
Smoking, exposure to benzidine and naphthylamines in the rubber, leather, and dye industries, treatment with cyclophosphamide (10% risk after 12 years of exposure), pelvic irradiation (for example, cervical cancer), persistent urinary tract infections, and schistosomiasis—early menopause has been demonstrated to raise risk by 50%. Adenocarcinoma is linked to patent urachus.
Epidemiology
2% of malignancies, the second most prevalent genitourinary system cancer; men are affected 2-3 times more frequently than women; rare <50 years; mean age at diagnosis in the sixties.
History
most frequently, macroscopic haematuria without discomfort. Urgency or nocturia, frequent urination, and recurrent UTIs are other symptoms. Pain from ureteral blockage, clot retention, or pelvic extension is infrequent.
Examination
Not many signs.
Palpable lymphadenopathy or bulk may indicate an advanced stage.
Investigational studies
Urine: Microscopy and culture in cytology.
Cystoscopy: Enables the tumor to be seen and removed or biopsied.
As tumors might have several locations, USS and IVU are used to evaluate the upper and lower urinary tracts.
MRI or CT scan: To stage.
TNM setting: That is, in situ flat cancer; T1, submucosal invasion of lamina propria; T2, muscle invasion; T3, perivesical tissue invasion; T4, invasion of neighboring organs or pelvic wall; N, nodal involvement; and M, metastases. T1a is a papillary tumor above the lamina propria.
70% are only superficial when they are first diagnosed.
G1, well-differentiated; G2, moderately-differentiated; and G3, poorly-differentiated are the three classifications.
Management
Depending on the tumor's grade and stage.
Tumors on the surface (Tis, T1): Bladder tumor transurethral resection (TURBT).
To lower recurrence rates, provide BCG injections as part of intravesical immunotherapy or mitomycin C-based intravenous chemotherapy. close monitoring using recurrent cystoscopy and bladder cytology every three months for two years, then every six months for another two years, and finally once a year. The optimum treatment for high grade T1 tumors might be a cystectomy. Nephro-ureterectomy may be necessary due to upper tract illness.
T2 and higher invasive tumors: radical cystectomy if localized (this involves bilateral salpingo-oopherectomy and hysterectomy in females, and cystoprostatectomy in males with ileal conduit urine diversion, orthoptic reconstruction, and pelvic lymph node dissection).
Robotic-assisted or laparoscopic surgeries can be performed by specialised centres.
Chemotherapy or radiation therapy: If surgery is not an option, radical radiation therapy with salvage cystectomy is an alternative for post-radiation relapse. In cases of metastatic disease, palliative radiotherapy and chemotherapy are utilized, such as M-VAC (methotrexate, vinblastine, doxorubicin, and cisplatin).
Complications
hydronephrosis brought on by blockage of the ureteric orifice, haematuria, and clot retention.
Surgery: Early: rectal damage, ileus, intestinal blockage, infection, and bleeding.
Late: fistula, hernia, nephrolithiasis, pyelonephritis, and bowel obstruction.
Radiation therapy: hemorrhage, bladder contraction, and post-radiation cystitis.
Prognosis
Of those who undergo TURBT, 75% will develop further tumors, although only 10% will advance to an invasive illness. T1 90–100%, T2 70–70%, T3 30–65%, and T4 10–20% five-year survival rates. 5 year survival with distant metastases is 6%.

Surgery - Orchitis and Epididymitis
Introduction
inflammation (orchitis) of the testes or epididymis. Most occurrences of orchitis are linked to epididymitis, while 60% of epididymitis cases are linked to orchitis.
Etiology
While one-third of cases are idiopathic, the majority have infectious origins.
Bacterial: less than 35 years, usually gonococcus or chlamydia. Most frequent organisms for more than 35 years are coliforms. Rarely: tertiary syphilis, tuberculosis.
Viral: coxsackie, EBV, mumps (orchitis frequently follows recent parotitis).
Fungal: If immunocompromised, Candida, for example.
Inflammatory conditions include post-vasectomy and Behcet's illness.
maybe connected to a testicular tumor underneath.
Epidemiology
Typical. Obviously exclusive to men.fifty to thirty years old.
H HISTORY
Testicles or epididymis that are sore, swollen, and sensitive (typically unilateral).
The most significant variation is that testicular torsion is more acute than onset.
Fever and penile discharge are possible side effects.
It's crucial to find out about past sexual experiences and any parotitis history.
Examination
Scrotal erythema and edema.
painful and swollen testicles and/or epididymis.
It could hurt to walk or even to trigger a cremaster response.
Check for parotid enlargement or soreness by palpating the parotid glands.
Pyrexia.
Prehn's sign: Pain in orchitis and epididymitis is relieved by elevating the scrotum, but not in torsion of the testicles.
Investigational studies
Midstream pee: MC&S; early urine collection in the morning (for AFB if TB risk exists).
Blood: mumps serology, elevated WCC, elevated CRP, and U&E.
Doppler ultrasonography of the testicles: To rule out torsion and local abscess.
Ultrasound of the abdomen: May be required to rule out bladder outflow restriction.
After the acute episode has been treated, follow-up imaging should be done to rule out testicular cancer.
Management
Medication: If necessary, antibiotics.
For two weeks, young patients should take quinolones that are active against chlamydia (levofloxacin, ofloxacin). As an alternative, think about doxycycline. pain relief and scrotal assistance.
Elderly patients: Quinolones for two weeks, such as ciprofloxacin.
An antituberculous treatment is required if TB is suspected.

It is advised to follow up in order to rule out testicular cancer.
Surgical: If testicular torsion cannot be ruled out or if a pyocoele or abscess develops that needs to be drained, a scrotal exploration may be required. Possibly required if a patient with tuberculosis does not improve with medication.
Public health: tracking down a contact, particularly if they are sexually active.
Complications
Infection and Fournier's gangrene could spread if the pain and abscess are not addressed. little danger to fertility if it is treated alone. Fifty percent of cases of mumps orchitis result in testicular atrophy (higher risk of infertility if bilateral).
Prognosis
I'm usually okay if I'm taken care of. It could take up to two months for the swelling to go away entirely.

Surgery - Hydrocoele
Definition
A fluid accumulation in the scrotum between the tunica vaginalis's parietal and visceral layers. A fluid collection in a portion of the processus that is closed off to the peritoneal cavity and tunica vaginalis is known as a hydrocoele of the cord (rare).
Etiology
Congenital: most often idiopathic; acquired: most usually congenital communication (or communicating, due to a patent processus vaginalis, the peritoneum that follows the fall of the testicle into the scrotum, with failure of obliteration leaving a tiny communication and peritoneal fluid routes into the tunica vaginalis).
Secondary reasons: Tumor, trauma, underlying torsion of the testicle or testicular appendage, parasite infection such as Wuchereria bancrofti or filariasis, or epididymo-orchitis may all be causes of infection.
Risk Factors
Children's indirect inguinal hernias. In the UK, epididymo-orchitis is a frequent cause. In nations where filariasis is highly prevalent, enormous hydrocoeles are caused by the disease.
Epidemiology
In male infants, a patent processus vaginalis is frequently present; by the time a child reaches two years old, it usually disappears. In older males, hydrocoeles are prevalent. The most frequent cause among adults worldwide is filariasis.
History
enlargement of the scrotum. often asymptomatic, but depending on the underlying etiology, it may be accompanied by discomfort or urine symptoms.
Examination
Scrotal enlargement (stiff or doughy), which can be surpassed; typically trans-illuminates and makes it challenging to feel the related testicle separately.
Investigational studies
Anechoic fluid accumulation encircling the testis's anterolateral aspect is visible on the ultrasound.
utilized to check for underlying tumors in the testicles as well.
Urine: MSU for infection, Dipstick.
Blood: If testicular tumors are suspected, markers (aFP, b-HCG) may be used.
Management
Most babies resorb on their own, and ligation of the patent processus at the deep ring via an inguinal approach is not performed until the child is one year old, frequently in conjunction with the correction of an inguinal hernia. Aspiration of the hydrocoele is not advised in adults because it tends to re-accumulate, introduces infection, or results in a haematocoele.
Surgical: The scrotal technique is typically utilized on adults. Extraneous tunica vaginalis can be removed, and the remaining tissue can be treated with either a Lord's treatment, which plicates the sac, or a Jaboulay procedure, which everts the sac.
It is necessary to treat the underlying cause of secondary hydrocoeles.
Complications
discomfort and swollen penis.
Infection, hemorrhage, damage to spermatic cord nerves or structures, and recurrence are among the surgical risks.
Prognosis
The recurrence incidence of idiopathic hydrocoeles is 1%–2% after surgical therapy, making them typically chronic. Once the predisposing condition has been treated, acute secondary hydrocoeles usually go away.
Definition
A fluid accumulation in the scrotum between the tunica vaginalis's parietal and visceral layers. A fluid collection in a portion of the processus that is closed off to the peritoneal cavity and tunica vaginalis is known as a hydrocoele of the cord (rare).
Etiology
Congenital: most often idiopathic; acquired: most usually congenital communication (or communicating, due to a patent processus vaginalis, the peritoneum that follows the fall of the testicle into the scrotum, with failure of obliteration leaving a tiny communication and peritoneal fluid routes into the tunica vaginalis).
Secondary reasons: Tumor, trauma, underlying torsion of the testicle or testicular appendage, parasite infection such as Wuchereria bancrofti or filariasis, or epididymo-orchitis may all be causes of infection.
Risk Factors
Children's indirect inguinal hernias. In the UK, epididymo-orchitis is a frequent cause. In nations where filariasis is highly prevalent, enormous hydrocoeles are caused by the disease.
Epidemiology
In male infants, a patent processus vaginalis is frequently present; by the time a child reaches two years old, it usually disappears. In older males, hydrocoeles are prevalent. The most frequent cause among adults worldwide is filariasis.
History
enlargement of the scrotum. often asymptomatic, but depending on the underlying etiology, it may be accompanied by discomfort or urine symptoms.
Examination
Scrotal enlargement (stiff or doughy), which can be surpassed; typically trans-illuminates and makes it challenging to feel the related testicle separately.
Investigational studies
Anechoic fluid accumulation encircling the testis's anterolateral aspect is visible on the ultrasound.

Surgery - Pancreatoduodenectomy, or Whipple's Procedure
Indications
tumors of the ampulla, distal common bile duct, duodenum, or head of the pancreas (usually, less than 20% of patients have curable disease).
Anatomy
In the transpyloric plane, the pancreas is a retroperitoneal structure. The head, neck, body, and tail make up the four sections. The duodenum's curvature contains the head.During a Whipple's procedure, the distal stomach, duodenum, head of the pancreas, distal common bile duct, and gallbladde are removed all at once (with the exception of pylorus-preserving pancreatectomy).
By creating a pancreaticojejunostomy, choledochojejunostomy, and gastrojejunostomy, one can maintain intestinal continuity. In recent times, there has been evidence that pylorus-preserving pancreaticoduodenectomy enhances gastrointestinal function, as demonstrated by reduced ulceration, dumping syndrome, and enhanced weight gain.
Vascular: The splenic and pancreaticoduodenal arteries provide blood to the pancreas.
The pancreaticoduodenal and splenic veins lead to the portal vein via venous drainage.
Investigations
Endoscopy/ERCP: histology and diagnosis.
Imaging: FDG-PET scans, endoscopic ultrasonography, angiography, CT, and MRCP for staging, diagnosis, and resectability evaluation.
FBC, U&E, LFT, CA19-9, and CEA in blood.
Pre-operative care may involve biliary decompression or stenting, blood and crossmatch, and multidisciplinary discussion. Use broad-spectrum antibiotics to cover.
Following surgery, post-operative treatment should include ICU/HDU supervision, insulin to regulate blood sugar, H2 receptor antagonists or proton pump inhibitors, octreotide and thromboprophylaxis, and, in the long run, pancreatic enzyme supplements. Perhaps adjuvant chemoradiotherapy is necessary.
Procedure
Supine position is used.
Rooftop, vertical midline, or transverse incisions are all possible.
Examination: Resectability of lesion and contents of abdomen assessed. Palliation via bypass, such as gastrojejunostomy and choledocho- or cholecystojejunostomy, if it is incurable.
Mobilization: In a pylorus-preserving surgery, the duodenum is mobilized (Kocherization) and the distal stomach is divided or the duodenum is divided 2 cm distal to the pylorus. Along with the gallbladder, common bile duct, and proximal pancreas, the duodenum is removed along with lymph nodes. To guarantee distinct margins during pancreatic resection, utilize frozen section. One can conduct an end-to-end or side-to-side pancreaticojejunostomy. An end-to-side pylorus-jejunotomy, end-to-side gastrojejunostomy, and end-to-side hepaticojejunostomy are made further downstream. You can create a feeding jejunostomy to provide nutritional support.
Conclusion: prudent hemostasis. The positioning of drains. Mass closure. Skin can be sealed using clips or subcuticular sutures.
Complications
The rate of morbidity is 40%. bleeding, dumping, reflux, anastomotic leak, biliary leak, ileus, hyperglycemia, sepsis from an abdomen or wound, delayed gastric emptying, pancreatitis, pancreatic fistula, and pancreatic insufficiency.
Prognosis
This is a significant surgical procedure that need to be carried out in specialized hospitals with current death rates around 5%. 30% of 5-year survival rates for resectable tumors.

Surgery - Achalasia
Introduction
an oesophageal motor condition characterized by loss of peristalsis during swallowing and failure of the lower oesophageal sphincter (LES) to relax.
Etiology
Impaired relaxation of the lower sphincter and disruption of peristaltic coordination are the results of degeneration of the intramural ganglions of the myenteric (Auerbach's) plexus. The deterioration may have an infectious or autoimmune cause, however this is uncertain. Similar symptoms can be brought on by the parasite protozoon Trypanosome cruzi, however this condition is exclusive to South America.
Epidemiology
0.5 out of 100,000 cases annually. mostly during the middle ages. Not a difference in race or gender.
History
Dysphagia involving solids and liquids, first intermittent. Weight loss, coughing/recurrent chest infections, atypical/cramping retrosternal chest discomfort or fullness, and regurgitating undigested food or retained saliva are prevalent.
Investigations
Barium swallow: The oesophagus's body lacks peristalsis, which smoothly tapers down to the lower oesophageal sphincter, giving the appearance of a bird's beak. Long-term condition characterized by tortuous dilated oesophagus with retained food, where CXR may reveal dilated oesophagus, double right heart border, and fluid behind heart shadow.Oesophagoscopy/endoscopic ultrasound: To rule out stricture or malignancy, as tumors may be the cause of pseudoachalasia. Although not required for diagnosis, a biopsy may reveal absence of nerve fibers or hypertrophy in the muscles.
Gastrointestinal manometry: The classic findings include aperistalsis of the oesophagus body, higher lower oesophageal sphincter pressure, and failure of the lower oesophageal sphincter to relax upon swallowing. "Vigorous" achalasia: a condition in which swallowing causes the oesophagus's body to flex violently and painfully.
Blood: It is rarely necessary to rule out Chagas' illness (testing positive for T. cruzi).
Management
Reducing the lower oesophageal sphincter pressure is the goal of all available treatments:
Medical: Pre-meals isosorbide mononitrate (short-term relief) or calcium channel antagonists such as nifedipine or verapamil.
Endoscopic: LES dilatation with a pneumatic balloon (80% success rate, slight perforation risk). More than 75% of patients find that injections of botulinum toxin into the lower epidermis (LES) are beneficial; nevertheless, symptoms usually return within six months, many treatments are needed, and responsiveness may deteriorate. Usually reserved for patients who are not a good fit for surgery or balloon dilatation.
Surgery: Heller's cardiomyotomy: anterior myotomy of LES is currently primarily carried out laparoscopically (although some centers use a robotic technique). To stop gastro-oesophageal reflux, fundoplication—typically anterior Dor—can be used in conjunction with Heller's cardiomyotomy. Results: decent to very good symptom relief.
Complications
Aspiration pneumonia, starvation, and weight loss could occur if left untreated. Over time, there is a higher chance of oesophageal cancer, particularly squamous cell carcinoma, hence endoscopic monitoring and biopsy are advised.
Of Heller's: Perforation (7–15%), elevated risk in patients with prior Botox injections because of reflux, submucosal fibrosis, and recurrence (early: scarring or technical failure, late: advancement of the disease).
Prognosis
There is no cure, however single or combination treatments can effectively manage up to 90% of patients.

Surgery - Gastric Cancer
Introduction
Adenocarcinoma is the most prevalent type of gastric cancer; lymphoma and leiomyosarcoma are less common.
Etiology
linked to atrophic gastritis and Helicobacter pylori infection.
Hereditary diffuse stomach cancer is caused by germline mutations in E-cadherin.
a diet heavy in processed and smoked foods, alcohol, smoking, and nitrosamines.
Blood type A (relative risk: 1.2).
Anemia pernicious.
prior partial stomach removal.
H. pylori infection has a very strong causative association with MALT lymphomas.
Epidemiology
Cancer is a common cause of mortality worldwide, with Eastern Europe, China, and Japan having the highest incidence. Incidence of the sixth most prevalent cancer in the UK is 15 per 100,000. Male to female ratio is 2:1.
Age of presentation is often over 50. Cancers of the body and antrum are declining, but those of the heart and gastro-oesophageal junction are rising.
History
Early asymptomatic; later, weight loss, anorexia, nausea, epigastric pain, indigestion, anemia, and gastrointestinal hemorrhage. Metastatic illness symptoms include jaundice (liver involvement) and distention of the abdomen (ascites).
Examination
Ascites and an epigastric mass are late indicators.
Signs of eponymy discovered in metastatic spread:
Virchow's node, also known as Troisier's sign, refers to palpable lymph nodes located in the left supraclavicular fossa.
The umbilicus has a metastatic nodule on Sister Mary Joseph's node.
& Krukenberg tumor: Spreads to the ovaries.
Investigations
Upper gastrointestinal endoscopy: Multi-quadrant biopsy for every stomach ulcer.
Determine the local lymph node involvement and the depth of stomach invasion (T stage) using endoscopic ultrasonography.
CT scan: Tumor staging.
Laparoscopy staging: Allows for the detection of local or transperitoneal spread.
Pathology:
Macroscopic: According to Borrmann's classification, polypoid, ulcerating, or infiltrative tumors; if widespread, they may result in linitis plastica, also known as leather-bottle stomach.
Internal and diffuse kinds are microscopic.
Management
Surgery: Subtotal or total gastrectomy (see Gastrectomies) is the cornerstone for early disease.
Dissection of lymph nodes classified as D1 (containing perigastric N1 nodes) and D2 (with N2 layer of nodes; proponents of the latter name are Japanese). elevated mortality and morbidity rates following D2 and overall gastrectomy. For staging, at least 15 nodes are needed.
Palliative care may involve procedures like gastrojejunostomy or stenting to keep enteral feeding going.
Medical: The MAGIC study, ECF chemotherapy, showed that neoadjuvant chemotherapy improved 5-year survival (36% against 23% for surgery alone).
Palliation is the goal of therapy for advanced illness. increased rates of response with combined treatment.
Complications
dysphagia, gastric outlet obstruction, iron deficiency anemia, and upper gastrointestinal bleeding. Gastrectomy side effects, both early and late (dumping syndrome, diarrhea, vitamin B12 deficiency, etc.).
Gastric cancers have the potential to spread haematogenously to the liver and lungs, transperitoneally, via lymph nodes, or directly through the stomach wall.
Prognosis
bad generally, with a 5-year survival rate of 20% (60% in Japan), greater in patients with early illness who are undergoing resection.
Staging: based on clinical and pathological data, either the Birmingham Staging method or the TNM method.

Surgery - Vasectomy
Indications
Contraception is optional (but it should be regarded as irreversible). Rarely, recurrent epididymitis (60 percent lower risk).
Anatomy
Spermatozoa generated in the testes are transported from the tail of the epididymis to the ejaculatory ducts via the vas deferens (ductus deferens). It passes via the inguinal canal and the scrotum and is 45 cm long. It enters the pelvis beneath the peritoneum that covers the lateral wall after passing across the external iliac artery. It joins the ipsilateral seminal vesicle at the ischial tuberosity, where it turns medially and crosses in front of the ureter to the base of the bladder. From there, it forms the ejaculatory duct, which passes through the prostate gland and opens into the prostatic urethra.
Vascular: The internal iliac artery supplies blood to the vas, which may be encased in venous varicosities, such as varicocele in the scrotum.
Investigations
Pre-op: Counseling and informed consent should be given by the patient and partner. The patient needs to be made aware that this surgery should be viewed as irreversible. Medical history is examined, and some medications are discontinued, such as aspirin one week before to surgery, if necessary.
Scrotal support is used for up to one week following surgery. A pair of distinct semen samples should verify azoospermia, and the patient should be cautioned to stick to pre-operative contraceptive treatments for a full 12-week period.
Actions
carried out while under local anesthesia. After shaving, skin needs to be washed with antiseptic. The two primary methods are no-scalpel and scalpel:
Scalpel: Holding the vas deferens between the thumb and two fingers, local anesthetic is injected, usually at the bilateral intersection of the middle and upper scrotal regions. On the scrotal surface, a tiny vertical incision is made above the vas. The surrounding tissue is cut away with a blunt knife, the vas deferens is extracted from the incision, and the middle portion is secured with a clip. A length (about 1-2 cm) is removed after the vas is tied.
Recanalization is stopped by cauterization to the severed ends, vas folding back, or fascial interposition. Haemostasis needs to be done carefully. Sutures that are simply interrupted are used to close the skin. The opposite side repeats this.
No-scalpel: A ring forceps is used to clamp the vas deferens when it has been felt beneath the skin. A dissecting forceps is used to puncture skin in order to create an opening. Using a ring clamp, the vas is extracted and treated similarly to a scalpel.
It is best to send the removed vas segment for histological confirmation.
Complications
Short-term: Sperm granuloma, epididymitis, haematoma, bruising, and infection.
Long-range: less than 1% of conceptions fail because of recanalization, surgical mistakes, anatomical variations, or ineffective contraception before azoospermia is confirmed.
Pelvic discomfort is not prevalent.
