Surgery - Anal fissure
Introduction
a fissure-in-ano, or extended ulcer in the lower anal canal's long axis.
Etiology
traumatic Constipation: the posterior anal lining is torn by straining and passing hard stool. After childbirth, anterior fissures are more common in women because the anterior anal tissues are less supported by a compromised pelvic floor. Inflammatory: ulcerative colitis, Crohn's disease.
Epidemiology
Most prevalent in those under 40. First incidence: 350, gender equals male.
History
intense scorching discomfort when passing gas. Patients may try to prevent bowel motions as a result of pain that lasts for hours. Bleeding per rectum is a regular occurrence; on paper, it typically appears bright red and modest in volume. Pruritus ani may be present in conjunction.
Examination
A sentinel pile is often visible upon inspection. The distal portion of the fissure can be seen by gently pulling on the anal skin. Pain may prevent a digital rectal examination from being performed. It could be able to feel a hard, indurated ridge in chronic cracks.
Pathogenesis
The sphincter muscle beneath the anal mucosa experiences a mechanical tear, resulting in spasm. In addition to being excruciating, the spasm exacerbates the issue by tearing the margins of the rip apart. Poor healing is a result of reduced blood flow in the posterior midline of the anoderm compared to other areas of the anal canal.
Investigational studies
A diagnosis may be reached by investigation and history. The goal of the investigation is to rule out other illnesses such rectal cancer and inflammatory bowel disease.
If treatment is not working, an examination under anesthesia is necessary to rule out additional pathologies.
Management
Conservative: Make sure the stools are easily passed and soft.
Medical: Diltiazem or topical GTN. They promote wound healing by decreasing sphincter spasm and boosting local blood flow.
Surgery: Traditionally, a partial lateral division of the internal sphincter is done during a lateral internal sphincterotomy to lessen spasm and facilitate posterior midline wound healing. The same result has been achieved more recently by paralyzing a portion of the internal sphincter with botulinum toxin, or Botox. flap of anal advancement in persistent fissures.
Complications
Both chronic pain and chronic fissure.
Recurrence of bleeding and faecal incontinence are among the surgical complications.
Prognosis
Recurrence is common, occurring in fewer than 10% of patients after lateral sphincterotomy and up to 50% of individuals treated with topical nitrates.

Surgery - Angiodysplasia
The most prevalent location for GI mucosal vascular ectasias, or dilatation, is the colon.
Etiology
Not precisely understood, but believed to be acquired as a degenerative process, potentially brought on by low-grade, persistent submucosal venous blockage.
The caecum and ascending colon are the usual sites of angiogenesis dysplasias, while the left colon can also be impacted.
Epidemiology
Present in 6% of patients having a colonoscopy for a variety of reasons, and more common in older people (25 percent in those over 60, with the majority staying asymptomatic).
History
presents with PR bleeding, which can be sudden, severe, and sporadic with a sudden cessation. Rebleeding happens frequently.
Examination
symptoms of shock in the event of a large blood loss (tachycardia, hypotension). No distinctive symptoms were found during the abdominal exam.
Investigations
Blood: crossmatch, FBC, U&Es, clotting, and six units if there is a substantial bleed.
Endoscopy: When the cause of a significant bleeding episode is uncertain, upper gastrointestinal endoscopy should be performed. colonoscopy when patient is stabilized and able to undergo bowel preparation.
Imaging: vascular tufts in the capillary phase and early filling of dilated veins (>1 mL/minute blood loss required to visualize bleeding source) are seen on an angiography of the superior or inferior mesenteric arteries. Radionucleotide scanning: RBCs labeled with 99mTc have a 0.5 mL/minute bleeding threshold, but they are not spatially discriminating.
Management
Emergency care should include blood transfusion if necessary, oxygenation, IV access, resuscitation, and assessment of hemodynamic condition. Give antifibrinolytics or treat any coagulopathy. Urinary catheterization and CVP monitoring may be required in cases of severe bleeding.
Endoscopic: During a colonoscopy, diathermy or photocoagulation may be used to treat. Lesions appear as flat, elevated, or tiny cherry-red patches on a colonoscopy. In 25% of cases, there are several.
Interventional radiology: targeted embolization of bleeding arteries and angiography (may result in major side effects, such as bowel ischaemia). Better than surgery since the bleeding spot could not be seen during the procedure.
Surgery: The need is determined by the severity and pace of blood loss, as well as the accessibility of interventional radiology. An on-table colonoscopy can be done to confirm the site of the bleeding after anterograde colon lavage, which involves inserting a catheter into the appendix stump. A segmental resection, primary anastomosis, or subtotal colectomy may then be carried out.
Complications
hemorrhage, shock from low blood volume, and problems from tests and therapy.
Prognosis
Bleeding typically stops on its own. In the coming years, 50% of patients who had bleeding episodes and were treated conservatively with transfusion and observation will likely experience more episodes.

Surgery - Colon Cancer
Introduction
Large bowel adenocarcinoma.
Etiology
Genetic and environmental variables have been linked. It is believed that a series of events, including the accumulation of genetic alterations, the activation of oncogenes (such APC and K-ras) and the inactivation of tumour suppressor genes (like p53 and DCC), leads from epithelial dysplasia to adenoma and ultimately carcinoma.
Risk Factors
polyps in the colon, a history of colorectal cancer, and inflammatory bowel disease, especially chronic ulcerative colitis. Lynch syndrome and familial adenomatous polyposis are two genetic syndromes linked to an increased risk.
Epidemiology
With 37,500 cases annually, cancer is the second cause of cancer death and the third most frequent cancer in the UK. 60–65 years old on average at diagnosis. Colon cancers: females > males, rectal carcinomas: males > females.
History
The location and size of the tumor affect the symptoms.
Through the NHS bowel cancer screening program, patients may come with positive faecal occult blood tests even when they are asymptomatic.
colon and rectum on the left side: altered bowel habits, rectal hemorrhage, or blood or mucus mixed with feces. Tenesmus, or the sense of incomplete emptying following bowel movement, is another symptom of rectal masses.
Right-sided colon: Later presentation characterized by anemia symptoms, weight loss, general malaise, or, in rare cases, lower abdominal pain.
About 20% of tumors will cause pain and distension in an emergency room due to major intestinal blockage, bleeding, or peritonitis from a perforation.
Examination
There might not be any indicators.
Particularly in cases of right-sided lesions, abdominal mass, hepatomegaly, metastatic illness, and "shifting dullness" of ascites, anemia may be the only symptom.
During a rectal examination, low-lying rectal tumors may feel palpable.
Pathogenesis
30% of the colon is in the ascending colon, 60% is in the rectum and sigmoid colon, and the remaining 40% is in the descending and transverse colon. Tumors can produce polypoid, exophytic masses or be annular, resembling "apple core" lesions. Duke and the TNM system are examples of staging systems.
Investigations
Blood: tumor markers (CEA to track therapy response or disease recurrence), LFT, and FBC (for anemia).
Blood in the stool: This test can be used to screen for occult or frank blood.
Endoscopy: colonoscopy and sigmoidoscopy. allows for biopsy and visualization. Isolated small carcinoma in situ lesions may be treated with polypectomy or endoscopic mucosal excision.
Imaging methods include endorectal ultrasonography, PET scanning, CT, MRI, and barium enema.
Management
By identifying and treating pre-malignant polyps and early illness, screening lowers mortality.
Operation: Depending on the stage and location, for example. Caecal tumors: Hemicilocectomy to the right. Right hemicolectomy extended for transverse colon tumors.
Left hemicolectomy for colon tumors that descend.
Sigmoid tumors: Resection anteriorly.
High mid-rectal: complete mesorectal excision combined with anterior resection.
If the tumor cannot be cleared, low rectal: abdominoperineal resection.
Emergency: Depending on the location and clinical presentation; examples include removal of a tumor, Hartmann's surgery, primary anastomosis, and a malfunctioning ileostomy.
Radiotherapy can be administered as adjuvant therapy to lower the chance of a local recurrence or as a neoadjuvant setting to downstage rectal tumors before resection.
Chemotherapy: For metastatic diseases or as an adjuvant treatment. 5-fluorouracil combination chemotherapy regimens are prevalent (e.g. FOLFOX). In cases of metastatic disease, chemotherapy is combined with bevacizumab (anti-vascular endothelial growth factor) or cetuximab (anti-epidermal growth factor receptor in the absence of a K-ras mutation).
Complications
Metastatic illness, recurrence, fistula formation, obstruction or perforation of the bowel.
Prognosis
varies according on the stage. It has been demonstrated that in situations that are treatable, those with poor mismatch repair have better outcomes.
Dukes Spread and 5-year survival extent:
An 90%–95% confined to the intestinal wall 77% C of serosa breached but no lymph nodes were affected serosa breached, including 48% of the lymph nodes D distant liver metastases The original Duke's staging does not include the 5–10% D stage.

Surgery - Colonic Polyps
A development or protrusion that extends into the colonic lumen from the gut wall.
Etiology
divided into two categories: neoplastic polyps (mostly benign adenomas, inflammatory pseudopolyps, hyperplastic polyps, hamartomatous polyps) and non-neoplastic polyps (mostly benign mucosal and submucosal proliferations) that are clinically relevant because they may develop into malignancies.
Among the several polyp syndromes are the following:
Characteristics of the Disorder
Peutz-Jeghers syndrome: diffuse gastrointestinal polyposis accompanied by mucocutaneous lip and gum discolorationbenign.
Multiple stomach, small, and large bowel adenomas are symptoms of familial polyposis coli.
APC gene with autosomal dominance. precancerous.
Gardner's syndrome is characterized by multiple colonic adenomas, osseomas, soft tissue tumors, sebaceous cysts, and congenital enlargement of the RPE. precancerous.
Turcot's syndrome: numerous colonic adenomas along with glioblastomas or medulloblastomas. precancerous.
Alopecia, nail atrophy, pigmentation, watery diarrhea, and numerous colonic adenomas are the symptoms of Cronkhite-Canada's syndrome. precancerous.
Epidemiology
Typical. Over 50% of people over 60 have the prevalence.
History
often asymptomatic, but can sporadically result in bleeding, mucoid diarrhea, anemia, or serve as a gateway for intussusception.
Examination
Usually no results from the analysis.
If low in the rectum, may be perceptible on PR examination.
Investigations
FBC blood (anemia).
Blood in the stool: frank or occult blood.
Endoscopy: The gold standard of investigation is a colonoscopy. An upper GI endoscopy is required to search for upper GI polyps in patients with multiple polyposis syndromes. To determine the type of excised polyp, a histological examination is required.
Management
Endoscopic procedures include endoscopic mucosal resection and polypectomy. For big rectal polyps, transanal endoscopic microsurgery is used.
Surgical: It can be necessary to remove large polyps by surgery. Early subtotal colectomy is advised in numerous polyposis syndromes (especially familial polyposis coli) in order to lower the risk of cancer.
Follow-up: Depending on the kind, size, and quantity of polyps, patients should undergo colonoscopies on a regular basis. In cases of numerous polyposis syndromes, families may need to undergo genetic screening.
Complications
The two malignant changes that carry the highest risk are multiple polyposis syndromes and villous adenomas.
Prognosis
If identified and treated prior to any malignant transformation, I'm good. Adenomas take around seven years to grow into cancer.

Surgery - Crohn's Disease
Introduction
inflammatory bowel illness that is transmural and granulomatous, affecting any region of the gastrointestinal system and lasting.
Etiology
Although the exact cause is unknown, it is believed to be a result of interactions between environmental and genetic variables.
Risk Factors
Genetic: HLA-B27 in cases of ankylosing spondylitis, NOD2 gene. Environmental: Refined sugar intake and smoking (4-6 times risk). Proposed link to infectious agents (e.g., mycobacterium).
Epidemiology
Incidence in the UK is 5–8/100,000. There are 50–80/100,000 cases. impact people of any age, although young individuals have the highest occurrence.
H HISTORY
Diarrhea (may be bloody or steatorrhea), crampy stomach pain (caused by transmural and peritoneal inflammation, fibrosis, or obstruction of intestine). fever, lethargy, and loss of mass.
signs of more issues.
Examination
Signs of anemia, weight loss, and clubbing.
oral pharyngitis, skin tags on the perianth, fistulae, and abscesses.
indications of potential difficulties.
Pathogenesis
Anywhere throughout the GI tract (40% involving the terminal ileum) might experience inflammation; these lesions show a mixture of normal and inflammatory bowel segments.mucosal oedema and ulceration accompanied by fistulae, abscesses, and "rose-thorn" fissures (cobblestone mucosa). persistent transmural inflammation accompanied by plasma cell, lymphocyte, and macrophage infiltration. Granulomata containing enormous epithelioid cells can be observed in lymphatic or blood arteries.
Investigations
Blood: hematinics (to check for deficient states), anti-Saccharomyces cerevisiae antibodies (ASCA), U&Es, LFT (reduced albumin), decreases in Hb, increased PLTs, and increased WCC.
stool culture and microscopy.
Visualization: AXR: toxic dilatation for blockages to the evidence. In the event of a perforation, erect the CXR.
Follow-up on the small intestine may show cobblestone mucosa, profound ulceration (rose-thorn), or fibrosis or strictures (string sign of Kantor).
MRI and CT scans for perianal illness.
Endoscopy (OGD, colonoscopy) and biopsy: May be helpful in distinguishing Crohn's disease from ulcerative colitis; also valuable in tracking the development of the disease and potential cancer.
Management
Acute exacerbation: High-dose 5-ASA analogs, such as mesalazine and sulphasalazine, antibiotics, IV or oral corticosteroids, fluid resuscitation, analgesia, and other treatments may cause a remission in Crohn's disease. Prevention of DVT is crucial if ill. Remission may be induced by an elemental diet (more typically employed in youngsters). Parenteral nourishment can be required.
Keep an eye on your body's temperature, pulse, breathing rate, blood pressure, and activity indicators including albumin, Hb, ESR, CRP, and platelets. Check for any issues. The Crohn's disease activity index, which includes scores for weight, hemoglobin, number of stools, abdominal pain, general wellbeing, symptoms connected to findings, and antidiarrheal medication, can be used to track improvement.
Long-term: Steroids for severe flare-ups, consistent 5-ASA analogs to lower the frequency of Crohn's disease relapses. Steroid-sparing medications (e.g., azathioprine, risk of bone marrow suppression) are used for maintenance. Fistulating illness is one of the severe or refractory conditions where the anti-TNF monoclonal antibody infliximab is administered.
Advice: Give up smoking and see a dietician. Instruction and guidance (from IBD nurse specialists, for example).
Surgery: Recommended when medical treatment fails, when a child does not thrive, or when complications arise. This does not stop recurrence because the illness can spread to other GI sites.
Complications
The following conditions can affect the digestive system: bleeding, intestinal strictures, perforations, fistulae (between the gut, skin, bladder, and vagina), perianal fistulae and abscesses, GI cancer (5% risk at 10 years), malnutrition, and inadequate nutrition.
Extraintestinal: erythema nodosum and pyoderma gangrenosum, amyloidosis, thromboembolism, arthropathy, sacroiliitis, gallstones, kidney stones, uveitis, episcleritis, arthropathy, and ankylosing spondylitis.
Prognosis
chronic illness that relapses. At some point, two thirds will need surgery, and two thirds of these will need more than one surgical treatment. higher risk of gastrointestinal cancer

Surgery - Diverticular Disease
Introduction
Diverticulae, or outpouchings of the colonic mucosa and submucosa through the large bowel's muscular wall, are indicative of diverticulosis.
Disease connected with diverticulitis: Diverticulitis linked to complications such as bleeding, infection, and fistulas.
Acute inflammation and infection of the colonic diverticulae is known as diverticulitis.
Classification of acute diverticulitis by Hinchey: Ia is phlegmon, II and III are localized abscesses, IV is faecal peritonitis, and VI is a perforation with purulent peritonitis.
Etiology
Loss of stool mass is a result of a low-fiber diet. High colonic intraluminal pressures are therefore required to force the stool through the muscularis, which causes the mucosa and submucosa to herniate.
Epidemiology
Colonic diverticulae are common (60 percent of persons in industrialized nations will acquire them), rare (less than 40 years). Diverticulae with a right slant are more prevalent in Asia.
History
80–90% of the time asymptomatic. PR bleeding, diverticulitis (usually), lower abdomen pain or the left iliac fossa, and fever are among the complications. Diverticular fistulation into the bladder causing recurrent UTIs, pneumaturia, and faecaluria.
Examination
Diverticulitis: sore abdomen; if a perforation has occurred, symptoms of localized or widespread peritonitis may be present.
Pathogenesis
Diverticulae can be right-sided, but they are most frequently found in the descending colon and sigmoid.
not present in the rectum. Herniated mucosa and submucosa via the muscularis, especially at areas of nutritional artery penetration, comprise diverticulae. The creation of fistulation or strictures, bacterial overgrowth, toxins, mucosal damage, diverticulitis, perforation, pericolic phlegmon, abscess, and ulceration can all result from proposed diverticular blockage caused by inspissated feces.
Investigations
Blood: FBC, elevated WCC and elevated CRP in cases of diverticulitis; if bleeding, examine coagulation and crossmatch.
Barium enema (air contrast): Shows pseudo-hypertrophy of circular muscle by displaying diverticulae with a sawtooth lumen appearance (should not be conducted in acute setting since there is a danger of perforation).
Flexible sigmoidoscopy and colonoscopy: This allows for the exclusion of additional pathologies, such as polyps or tumors, and the observation of diverticulae.
Check for signs of diverticular disease and consequences with a CT scan in an urgent situation.
Management
High-fibre diet (20–30 g/day): asymptomatic. Research is being done to see if probiotics and anti-inflammatories like mesalazine can stop diverticulitis from flare-ups repeatedly.
GI bleeding: IV rehydration and, if required, blood transfusions are frequently used as conservative measures to treat PR bleeding. embolization, angiography, and, if necessary, surgery.
IV antibiotics, fluid rehydration, and bowel rest are the treatments for diverticulitis. Drains placed radiologically may be used to treat localized collections or abscesses.
Surgery: May be required if there are repeated episodes or if complications like perforation and peritonitis arise. There are two types of surgery: open and laparoscopic.
Open: One-stage resection and anastomosis (leak risk) defuncting stoma; Hartmann's operation (resection and stoma). Laparoscopic drainage, peritoneal lavage, and drain insertion have shown promise in recent years.
Complications
Haemorrhage, fistula formation (bladder, small intestine, vagina), colonic blockage, diverticulitis, pericolic abscess, perforation, faecal peritonitis, and so on.
Prognosis
Between ten and twenty-five percent of people will get diverticulitis at least once. Thirty percent of them will have another incident.
Introduction
Diverticulae, or outpouchings of the colonic mucosa and submucosa through the large bowel's muscular wall, are indicative of diverticulosis.
Disease connected with diverticulitis: Diverticulitis linked to complications such as bleeding, infection, and fistulas.
Acute inflammation and infection of the colonic diverticulae is known as diverticulitis.
Classification of acute diverticulitis by Hinchey: Ia is phlegmon, II and III are localized abscesses, IV is faecal peritonitis, and VI is a perforation with purulent peritonitis.
Etiology
Loss of stool mass is a result of a low-fiber diet. High colonic intraluminal pressures are therefore required to force the stool through the muscularis, which causes the mucosa and submucosa to herniate.
Epidemiology
Colonic diverticulae are common (60 percent of persons in industrialized nations will acquire them), rare (less than 40 years). Diverticulae with a right slant are more prevalent in Asia.
History
80–90% of the time asymptomatic. PR bleeding, diverticulitis (usually), lower abdomen pain or the left iliac fossa, and fever are among the complications. Diverticular fistulation into the bladder causing recurrent UTIs, pneumaturia, and faecaluria.
Examination
Diverticulitis: sore abdomen; if a perforation has occurred, symptoms of localized or widespread peritonitis may be present.
Pathogenesis
Diverticulae can be right-sided, but they are most frequently found in the descending colon and sigmoid.
not present in the rectum. Herniated mucosa and submucosa via the muscularis, especially at areas of nutritional artery penetration, comprise diverticulae. The creation of fistulation or strictures, bacterial overgrowth, toxins, mucosal damage, diverticulitis, perforation, pericolic phlegmon, abscess, and ulceration can all result from proposed diverticular blockage caused by inspissated feces.
Investigations
Blood: FBC, elevated WCC and elevated CRP in cases of diverticulitis; if bleeding, examine coagulation and crossmatch.
Barium enema (air contrast): Shows pseudo-hypertrophy of circular muscle by displaying diverticulae with a sawtooth lumen appearance (should not be conducted in acute setting since there is a danger of perforation).

Surgery - Lower Gastrointestinal Hemorrhage
Introduction
bleeding coming from the digestive tract's lower region, or from a location distal to the Treitz ligament.
Etiology
Colic polyps or carcinoma, anal fissures, haemorrhoids, diverticular disease and angiodysplasia (60–70%), and colitis (inflammatory, ulcerative, infectious, ischemic, radiation). Rarer conditions include endometriosis, small intestinal tumors, aorto-enteric fistula, Meckel's diverticulum, and a single rectal ulcer. Bleeding PR can occur in conjunction with brisk upper GI bleeding.
Epidemiology
Common, however less common than upper gastrointestinal bleeds (10–30% of GI bleeds).
more typical among older people.
H HISTORY
Fresh bleeding or bloody diarrhea suggests a hemorrhage that is distal to the caecum.
Cause-suggestive history: inflammatory bowel disease, for example.
Examination
indicators of chronic iron deficient anemia.
symptoms of shock, tachycardia, orthostatic or overt hypotension, and acute hypovolemia.
Investigation
Blood: FBC, U&Es, clotting, LFT, and blood crossmatching in extensive hemorrhages. The detection of occult blood loss is accomplished using fecal occult blood tests, or guaiac.
Endoscopy: Sigmoidoscopy/colonoscopy; blood will obstruct vision unless the bleeding rate is moderate. It can be utilized for colonic lesion diagnosis and therapy once the bleeding has stopped. OGD to rule out upper GI causes in severe, rapid bleeding.
Mesenteric angiography: Can identify the location of bleeding (sensitivity < 60%); however, to show the site, the bleeding rate needs to be more than 0.5 mL/minute and must occur during the contrast injection. The usage of CT and MR angiography is growing.
Scintigraphy: A radiolabelled 99mTc-RBC scan is less accurate in its particular localization and can detect bleeding at a rate of 0.1–0.35 mL/minute. Technetiumscan: for Meckel's diverticulum-related ectopic stomach mucosa.
Laparotomy and enteroscopy: Using an endoscope inserted through the gut wall, the whole colon and small bowel are examined for internal and exterior lesions.
Management
Sufficient IV access, proactive resuscitation, and coagulopathy correction include resuscitation.
OGD and NG tube search for an upper GI source. In cases of substantial bleeding, close observation in an ICU or HDU is necessary. The majority will accept cautious management.
Interventional radiology includes vasopressin infusion and angiography for bleeding vessel localization and transcatheter embolization.
Endoscopic: Lower GI endoscopy, such as laser photocoagulation of angiodysplasia, may also be used to treat the cause in stable individuals.
Surgical: A subtotal colectomy may be necessary in cases of severe or recurring bleeding, or if endoscopic or angiographic treatment is not feasible or has not worked.
Complications
anemia, shock from low blood volume, and collapse.
Prognosis
Depending on the reason, most will finish on their own. Diverticular illness is the most prevalent cause of potentially fatal lower gastrointestinal bleeding; yet, 90% of diverticular bleeding will resolve with conservative treatment. Early management and forceful resuscitation enhance the prognosis in cases of serious GI bleeding.

Surgery - Acute Pancreatitis
Introduction
a pancreatic acute inflammatory condition that may or may not infiltrate distant organ systems or other local tissues. Mild: Linked to little organ dysfunction and a smooth recuperation. Severe: Linked to local consequences like necrosis, abscess, or pseudocyst, as well as organ failure (1992 Atlanta Classification).
Etiology
Insult causes tissue damage and inflammation by activating pancreatic proenzymes within the ducts and acini. Gallstones and alcohol are the most prevalent (80% instances). Infectious diseases (such as mumps, EBV, CMV, Coxsackie B, mycoplasma), drugs (such as steroids, azathioprine, thiazides, valproate), trauma, ERCP or abdominal surgery, hyperlipidemia, hyperparathyroidism, structural diseases (such as pancreatic divisum, annular pancreas), and idiopathic diseases are among the others.
Epidemiology
Typical. UK incidence per year is 10/10,000. Peak age is sixty years; gallstones are the main cause in women, whereas alcohol-induced illness is more common in men.
History
severe stomach or epigastric discomfort that radiates to the back and is made worse by moving or is eased by sitting forward. linked to nausea, vomiting, and anorexia. Alcohol consumption or gallstones may run in the family.
Examination
Fever and soreness in the stomach. tachycardia, tachypnea, and shock. #bowel noises as a result of ileus. If severe and hemorrhagic, consider either Cullen's sign (periumbilical bruises) or Turner's sign (flank bruises).
Investigations
Blood tests: high lipase, FBC (increased WCC), U&Es, elevated glucose, increased CRP, decreased Ca2+, elevated Amylase (typically >3 normal but does not correlate with severity), LFTs (may be deranged if gallstone pancreatitis or alcohol), and ABG (for hypoxia or metabolic acidosis). USS: For biliary dilatation or gallstones. Pleural effusion may be present in an erect CXR. primarily to rule out other explanations. AXR: To rule out alternative reasons for the acute abdomen. Maybe Psoas's shadow is gone. CT scan: In cases where there is doubt about the diagnosis, ongoing organ failure, or indications of necrosis, degeneration, or sepsis. Balthazar score: a scoring system that combines the degree of necrosis and the pancreatitis grade.
Management
Severity assessment: The following two measures have received the greatest validation: A combination of the modified Glasgow criteria and CRP (>220 mg/L) 2. The score on the APACHE-II (see to Gut 1998;42(Suppl 2):S1–S13). As an alternative, consider Ranson's requirements.†
Glasgow criteria modified (a score of three or above denotes a serious illness):
pO2 < 8 kPa (uR) in (P) > 16 mmol/L of urea (A) Over 55 years old (Enz) > 600 units/L (N) for LDH WCC > 15 109/L (A) < 32 g/L albumin (sugar) CA2+ < 2 mmol/L and glucose > 10 mmol/L †
Ranson's criteria (specific to pancreatitis caused by alcohol): Upon admission: hyperglycemia >11 mmol/L, AST >250, LDH >350, age >55, and WCC > 16109/L. pO2 < 8 kPa, Ca2Í < 2 mmol/L, urea > 16 mmol/L, base deficit > 4, haematocrit decline >10%, fluid sequestration > 600 ml within the first 48 hours.
Medical: NG tube if vomiting, urinary catheter, fluid and electrolyte replacement. management of blood sugar and analgesia. If severe, early HDU or critical care support. Enteral feeding, as opposed to parenteral feeding, has been proven in meta-analyses to reduce infective complications and mortality in cases of severe pancreatitis. It has not been demonstrated that preventive antibiotics lower mortality rates, unless infected pancreatic necrosis occurs. ERCP with sphincterotomy: Preferably within 72 hours for gallstone pancreatitis, cholangitis, jaundice, or dilated common bile duct. Within two weeks after admission, or on the same visit, all patients should receive definitive care for their gallstones. Early detection and treatment of complications: according to BSG guidelines, image-guided fine-needle aspiration for culture should be performed if there are persistent symptoms, more than 30% pancreatic necrosis, or evidence of sepsis. Surgical: A specialized facility should be used to address patients with necrotizing pancreatitis. Open necrosectomy or minimal access (draining and debridement of all necrotic tissue).
Complications
Local conditions include pancreatic necrosis, ascites, pseudo-aneurysm, abscess, pseudocyst (peripancreatic fluid accumulation lasting longer than four weeks), and venous thrombosis. Systemic: hypocalcemia, diabetes, ARDS, DIC, sepsis, renal failure, and hypocalcemia. Long-term: Diabetes and malabsorption together with chronic pancreatitis.
Prognosis
80% have a milder course with 5% mortality, while 20% have a severe fulminating course with significant mortality (infected pancreatic necrosis linked to 70% mortality).

Surgery - Salivary Gland Tumours
Introduction
tumors with a variety of histological subgroups that originate in either the major (parotid, submandibular, sublingual) or small salivary glands. 15% arise in the submandibular glands (30–50% malignant); 20% arise in the parotid glands (20% malignant); and 15% arise in the small salivary glands (>60% malignant). Less than 0.3 percent of sublingual gland tumors are malignant.
Etiology
Unknown Causes
Risk Factors
The following environmental factors have been identified: Epstein-Barr virus with lymphoepithelial tumors; smoking (Warthin's); radiation (Warthin's and mucoepidermoid carcinomama).
Epidemiology
comparatively uncommon; most affect adults. Pleomorphic adenoma has an average age of 42 years, Warthin's tumor has an average age of 60 years (male > female), acinic cell carcinoma affects women in their 50s, and squamous carcinomas attack men in their 70s.
History
A swelling that normally grows slowly and without pain. A malignant tumor increases the likelihood of pain.
Examination
Examining the edema and looking for indications of fixation is important. induration or ulceration of the mucosa or skin underlying it in locally advanced instances. One should use both hands to palpate the submandibular gland. examination of the mouth cavity because parapharyngeal space might become inflamed by deep lobe parotid tumors. facial nerve function in parotid lesions and signs of regional lymphadenopathy; weakness in this area should increase the possibility of malignancy.
Investigations
Imaging: To define the mass and its position in relation to adjacent structures and staging, ultrasound, CT, or MRI scans are utilized.
Tissue biopsy: FNA is a useful tool, however it is not a 100% reliable method for histological diagnosis.
Because of the possibility of tumor spilling, incisional or excisional biopsy of tumors in large glands should be avoided.
Histopathology:
& benign tumors About 80–85% of parotid gland tumors are pleomorphic adenomas. lack of a real capsule in epithelium or myoepithelial cells, which explains their propensity to regrow following excision.
Once called as adenolymphoma, Warthin's tumor (papillary cystadenoma lymphomatosum) accounts for 15% of parotid neoplasms and 10% of bilateral or multicentric tumors with glandular, cystic, and eosinophilic epithelium.
& Malignant carcinomas: Parotid cancer is the most common type of acinic cell carcinoma. broad histological spectrum accompanied with lymphocyte infiltrations.
The most prevalent malignant tumor of the parotid gland, mucoepidermoid carcinoma can range in malignancy from low grade to severe.
& Adenoid cystic carcinoma: aggressive with a perineural spread into the brain and the potential for late metastases; it is the sixth most common malignant carcinoma of the submandibular region.
& Aggressive forms of adenocarcinoma, squamous, and undifferentiated carcinomas.
& Non-epithelial tumors (such as lymphomas and haemangiomas): Very uncommon.
Management
Medical: Saved for infectious tumors or lymphomas.
Surgical: Both benign and malignant tumors can be removed.
Superficial or whole parotidectomy, with careful preservation of the facial nerve and its branches that pass between the deep and superficial lobes, is the treatment for parotid-related benign or low-grade cancers. Should the nerve be affected, it is possible to undertake sacrifice and prompt reconstruction using a nerve graft.
Submandibular: An incision in the submandibular triangle is used to address tumors.
Resection may be required if malignant tumors involve the lingual or hypoglossal nerves. This causes a partial loss of sensation and tongue movement; the patient should be informed of this. Additionally, there's a chance of harming the facial nerve's mandibular branch, which could cause asymmetry in the mouth and lower lip. If there is involvement of lymph nodes, neck dissection is done.
Palate cancers: Usually require a large excision and intricate repair.
Therapy: If the tumor is malignant, adjuvant post-operative radiotherapy ought to be administered.
Chemotherapy: Usually used for palliation, although not very effective.
Complications
Following a parotidectomy, there may be facial nerve damage, bleeding, necrosis of the skin flap, salivary fistula, and Frey's syndrome (10–50%), which is characterized by abnormal regeneration of postganglionic parasympathetic nerve fibers that typically innervate the parotid to sympathetic nerves of the sweat glands, causing gustatory sweating. Pleomorphic adenomas, because they feature pseudopod-like extensions extending from the tumor, are prone to recurrence even with simple enucleation.
Prognosis
If left untreated, pleuromorphic adenomas gradually increase and carry a 5% risk of developing into malignant transformation. Five-year survival for mucoepidermoid carcinoma is 70%; higher-grade types have a worse survival rate. Because perineural invasion is difficult to eliminate and has a tendency for late recurrence, adenoid cystic carcinoma has a poor prognosis. Only 25–50% of high grade tumors have a 10-year survival rate, compared to 80–95% for low grade tumors.

Surgery - Thyroid Cancer
Overview
Thyroid gland cancer; varieties include anaplastic, follicular, medullary, and papillary tumors.
Risk Factors
Radiation exposure throughout childhood (papillary tumors). connected to p53 gene alterations and the MAPK pathway. Thyroid cancers in the medullary gland that are linked to MEN syndrome type IIa or IIb (20% of cases) may run in families. Thyroiditis caused by Hashimoto's is linked to lymphoma.
Epidemiology
most prevalent endocrine cancer. 8.2/100,000 is the increase in incidence. The ratio of women to men is 3:1.
Anaplastic tumors usually develop in older age groups: papillary 20–40 years, follicular 40–50 years.
History
A nodule, lump, or thyroid that grows slowly.
The patient can report having trouble swallowing or having a raspy voice.
Examination
a generalized thyroid enlargement or a palpable nodule. It is important to detect cancer if the cervical nodes are enlarged. Typically, the patient has euthyroidism.
Investigation
Blood: TFT (thyroglobulin, a tumor marker for papillary and follicular tumors, if hyperthyroid, thyroid nodule is less likely to be malignant), bone profile, and calcitonin, a tumor marker for medullary cancer.
Histological diagnosis is possible by core needle biopsy guided by ultrasonography or FNA cytology (FNAC). If a cervical lymph node is swollen, a lymph node biopsy may be necessary.
Imaging methods include bone scans, CT and/or MRI staging, ultrasound, and isotope scanning.
Histology: & Seventy percent of papillary adenocarcinomas are multi-focal, with "orphan Annie"—pale, empty, and grooved nuclei—being one of their hallmarks. They spread quickly and infiltrate lymphatics.
& 15% of encapsulated follicular adenocarcinomas disseminate hemorrhagically to the lung and bone. Since vascular and/or capsular invasion determines malignancy, FNAC cannot diagnose follicular tumors.
& Five to ten percent of medullary adenocarcinomas are strongly differentiated, originating from C cells that secrete parafollicular calcitonin.
& Anaplastic carcinomas are very aggressive, pleomorphic, undifferenciated tumors that stain for cytokeratins.
& Lymphomas typically include diffuse B cells and are uncommon (2.5% of extra nodal lymphomas).
Surgical management involves a total thyroidectomy along with block dissection of any lymph nodes that are impacted. For papillary tumors that are well-localized, a subtotal thyroid lobectomy may be necessary. Since anaplastic tumors are typically hard-fixed masses, the sole treatment options may be tracheal compression and local debulking.
Medical: Thyroxine medication to decrease remaining tumor cells in papillary and follicular tumors (which may be activated by TSH) and prevent hypothyroidism after surgery. Chemotherapy with doxorubicin is used for anaplastic tumors.
Radiological: 131I-radioiodine therapy for metastases, recurrences, and papillary tumors that extend outside of the capsule. External radiation therapy for regional relapses.
Tumors that are anaplastic are not very responsive.
Complications
Dysphonia, hoarseness from involvement of the recurrent laryngeal nerve, airway obstruction, tracheomalacia from compression, and dysphagia are symptoms of the condition.
Following surgery, there was laryngeal oedema, hypoparathyroidism, hypothyroidism, recurrent laryngeal nerve injury, and superior laryngeal nerve paresis.
Prognosis: Tumor type, size, and stage are significant variables. Overall survival for medullary carcinomas is 90% (node negative) and 50% (node positive) after 5 years; this survival is lowest in men and individuals over 50. Follic carcinomas have an overall survival of 85% after 5 years. The best patients for papillary carcinomas are those under 40 with tumors smaller than 1.5 cm. Within the capsule, lymphomas have a 5-year survival rate of 85%; however, with local dissemination, this number lowers to 40%. The prognosis for anaplastic carcinomas is extremely bad.
Overview
Thyroid gland cancer; varieties include anaplastic, follicular, medullary, and papillary tumors.
Risk Factors
Radiation exposure throughout childhood (papillary tumors). connected to p53 gene alterations and the MAPK pathway. Thyroid cancers in the medullary gland that are linked to MEN syndrome type IIa or IIb (20% of cases) may run in families. Thyroiditis caused by Hashimoto's is linked to lymphoma.
Epidemiology
most prevalent endocrine cancer. 8.2/100,000 is the increase in incidence. The ratio of women to men is 3:1.
Anaplastic tumors usually develop in older age groups: papillary 20–40 years, follicular 40–50 years.
History
A nodule, lump, or thyroid that grows slowly.
The patient can report having trouble swallowing or having a raspy voice.
Examination
a generalized thyroid enlargement or a palpable nodule. It is important to detect cancer if the cervical nodes are enlarged. Typically, the patient has euthyroidism.
Investigation
Blood: TFT (thyroglobulin, a tumor marker for papillary and follicular tumors, if hyperthyroid, thyroid nodule is less likely to be malignant), bone profile, and calcitonin, a tumor marker for medullary cancer.
Histological diagnosis is possible by core needle biopsy guided by ultrasonography or FNA cytology (FNAC). If a cervical lymph node is swollen, a lymph node biopsy may be necessary.
Imaging methods include bone scans, CT and/or MRI staging, ultrasound, and isotope scanning.
Histology: & Seventy percent of papillary adenocarcinomas are multi-focal, with "orphan Annie"—pale, empty, and grooved nuclei—being one of their hallmarks. They spread quickly and infiltrate lymphatics.
& 15% of encapsulated follicular adenocarcinomas disseminate hemorrhagically to the lung and bone. Since vascular and/or capsular invasion determines malignancy, FNAC cannot diagnose follicular tumors.
& Five to ten percent of medullary adenocarcinomas are strongly differentiated, originating from C cells that secrete parafollicular calcitonin.
& Anaplastic carcinomas are very aggressive, pleomorphic, undifferenciated tumors that stain for cytokeratins.
& Lymphomas typically include diffuse B cells and are uncommon (2.5% of extra nodal lymphomas).
Surgical management involves a total thyroidectomy along with block dissection of any lymph nodes that are impacted. For papillary tumors that are well-localized, a subtotal thyroid lobectomy may be necessary. Since anaplastic tumors are typically hard-fixed masses, the sole treatment options may be tracheal compression and local debulking.
Medical: Thyroxine medication to decrease remaining tumor cells in papillary and follicular tumors (which may be activated by TSH) and prevent hypothyroidism after surgery. Chemotherapy with doxorubicin is used for anaplastic tumors.
Radiological: 131I-radioiodine therapy for metastases, recurrences, and papillary tumors that extend outside of the capsule. External radiation therapy for regional relapses.
