Abdominal tuberculosis is a common extrapulmonary manifestation of tuberculosis that most commonly involves the ileocaecal region of the small intestine. It can present with nonspecific constitutional symptoms like fever, weight loss, or abdominal pain. Diagnosis is challenging as findings can mimic other diseases like Crohn's disease, but imaging modalities like ultrasound, CT scan, and barium studies can reveal features suggestive of abdominal tuberculosis like enlarged lymph nodes, bowel wall thickening, strictures, and ascites. Blood tests are often nonspecific but may show elevated ESR or mild anemia. Sputum tests have low yield for diagnosis but help evaluate for concurrent pulmonary tuberculosis. Tissue sampling is often needed for confirmation.
Lower gastrointestinal tract bleeding can be caused by various conditions affecting the colon and small intestine. The most common cause is diverticular disease, followed by hemorrhoids. Bleeding may present as hematochezia, melena, or occult bleeding resulting in anemia. Colonoscopy is the primary diagnostic tool for evaluating the source and managing bleeding, while other modalities like capsule endoscopy and angiography can also be used. Treatment depends on the underlying cause and may involve endoscopic therapies, medications, or surgery.
Abdominal tuberculosis is most commonly seen in the ileocecal region due to factors like stasis and abundant lymphoid tissue. It typically presents with abdominal pain and a mass in the right lower quadrant. Diagnosis involves imaging studies like ultrasound and CT scan showing thickened bowel walls and enlarged lymph nodes. Confirmation is by biopsy and PCR analysis. Treatment involves anti-tubercular drugs for 6-9 months along with surgery for complications like obstruction or hemorrhage. Prognosis is generally good with medical management but depends on early diagnosis and treatment.

Massive lower gastrointestinal bleeding is a life-threatening condition defined by transfusing at least 4 units of blood in 24 hours, hemodynamic instability, or a hematocrit of less than 6g/dl. The main causes are diverticulosis (60%), unknown (13%), hemorrhoids (11%), and neoplasia (9%). Management involves resuscitation, risk assessment, blood transfusions, endoscopy for diagnosis and treatment, and angiography for patients with ongoing bleeding or when endoscopy fails to identify the source. Colonoscopy has high sensitivity but requires bowel preparation, while angiography can localize active bleeding but the patient must be stable. Endoscopic treatments include clips, thermal coagulation, and injections.

Radiologically, TB often shows involvement of the ileocecal junction and ascites, while Crohn's can display skip lesions and transmural inflammation. Histopathologically, TB granulomas are typically larger and show caseation, while Crohn's granulomas are often smaller and single. Microbiological tests like PCR and
Angiodysplasia is a vascular malformation that commonly affects the ascending colon and caecum of elderly patients. It is associated with age and can cause intermittent bleeding that ranges from subtle to brisk. The bleeding is often due to dilated, tortuous submucosal veins or vessels replacing the mucosa. Diagnosis involves colonoscopy, which reveals small reddish lesions, or other techniques like capsule endoscopy, angiography, or scans. Treatment focuses on cauterization or embolization of bleeding vessels during colonoscopy or angiography. For severe uncontrolled bleeding, surgery may be needed to locate and remove the bleeding segment of colon.
Acute calculous cholecystitis is caused by obstruction of the cystic duct by a gallstone. Symptoms include biliary colic, fever, and right upper quadrant pain. Ultrasound and hepatobiliary scintigraphy can diagnose thickened gallbladder walls and obstruction. Treatment involves early laparoscopic cholecystectomy for mild cases, or initial conservative treatment with antibiotics and potential percutaneous cholecystostomy for severe cases presenting with sepsis, with delayed cholecystectomy once the patient improves. Guidelines recommend early surgery for mild disease and initial medical management for severe acute cholecystitis.

This document discusses the case of a 55-year-old male patient who underwent surgery for small bowel stricture suspected to be lymphoma. The patient had a 10-year history of right lower abdominal pain and recent weight loss. Imaging and biopsy results were presented from the case. The surgical specimen showed diffuse ganglioneuromatosis of the intestine, a rare condition characterized by proliferation of nerve cells and fibers in the gastrointestinal tract.
Gastric outlet obstruction has various causes including peptic ulcer disease, gastric cancer, and Crohn's disease. It leads to vomiting of partially digested food, dehydration, and metabolic abnormalities. Diagnosis involves imaging, endoscopy, and biopsy. Management focuses on correcting electrolyte abnormalities and removing the mechanical obstruction endoscopically or surgically via procedures like vagotomy and gastrojejunostomy. Gastric cancer is a common cause and may require total or subtotal gastrectomy depending on location, with postoperative risks of bleeding, leakage, and nutritional deficiencies. Palliative options for inoperable tumors include stenting or bypass procedures.
Abdominal TB can involve any part of GIT from mouth to anus, the peritoneum and pancreato-billiary system.
Total EP TB accounts for about 10-12% of total no. of TB cases, out of which 11-16% are abdominal koch.
Sixth most frequent EP TB after lymphatics, genitourinary, bone & joint, milliary & meningeal TB.
Caused by M. tuberculosis, M. bovis & NTM.
Age group 20-40 most commonly affected & slight female preponderance has been described.
Before era of HIV infection > 80% TB was confined to lung
Extrapulmonary TB increases with HIV
40 –60% TB in HIV+ pt are extrapulmonary
Globally, proportion of co-infected pt > 8 %
~ 0.4 million people in India are co-infected.

Abdominal tuberculosis is the third most common form of extrapulmonary tuberculosis. It can affect any part of the gastrointestinal tract from mouth to anus. The most common sites of involvement are the ileocecal region and ascending colon. Patients typically present with abdominal pain, weight loss, fever, and diarrhea or constipation. Diagnosis is based on clinical features, imaging, endoscopy, histology, and culture of tissue samples. Treatment involves a 6-month course of anti-tubercular medications with surgery for complications like obstruction or perforation. A high index of suspicion is needed for early diagnosis and management of this potentially lethal but curable disease.
Abdominal tuberculosis is a condition caused by Mycobacterium tuberculosis infection of the peritoneum or abdominal organs. The most common site of involvement is the ileocaecal region of the small intestine and large intestine junction. Symptoms vary depending on the specific site of infection but can include abdominal pain, fever, weight loss, ascites, or the presence of a palpable abdominal mass. Diagnosis is supported by ascitic fluid analysis, imaging, endoscopy, and biopsy showing caseating granulomas. Treatment involves a standard combination of antitubercular drugs including isoniazid, rifampin, pyrazinamide, and ethambutol.
This document discusses abdominal tuberculosis, specifically focusing on tuberculosis of the gastrointestinal tract. It covers the pathogenesis, clinical features, diagnosis, and treatment of abdominal tuberculosis. The key points are:

ABDOMINAL TRAUMA in pediatrics part one.drhasanrajab
Abdominal trauma in pediatrics refers to injuries or damage to the abdominal organs in children. It can occur due to various causes such as falls, motor vehicle accidents, sports-related injuries, and physical abuse. Children are more vulnerable to abdominal trauma due to their unique anatomical and physiological characteristics. Signs and symptoms include abdominal pain, tenderness, distension, vomiting, and signs of shock. Diagnosis involves physical examination, imaging studies, and laboratory tests. Management depends on the severity and may involve conservative treatment or surgical intervention. Prevention is crucial in reducing the incidence of abdominal trauma in children.
