Laparoscopic greater curvature plication (LGCP) is relatively a new procedure. We report a novel complication of obstructive jaundice in a 24-year-old patient post LGCP. This was secondary to gastric mucosa prolapse with obstruction of the ampulla of Vater. A literature review revealed no previous reports of similar complication.

Heterotopic pancreas is defined as the presence of pancreatic tissue at sites other than the pancreas. Involved sites may be the stomach, duodenum, proximal jejunum, ileum, congenital duodenal web, Meckel's diverticulum, ampulla of Vater, and the main pancreatic duct. We report the magnetic resonance cholangiopancreatography findings of a patient who had biliary obstruction due to heterotopic p...

Signet ring cell carcinoma of the ampulla of Vater is extremely rare. The 7 cases reported earlier have been in older patients. We report a 32-year-old lady with this condition, who also had metastases in the bone marrow, vertebrae, lungs and liver.

We studied reactivity of cytokeratins (CK) 7, 17, and 20 in 64 pancreaticobiliary adenocarcinomas to examine the effect of different cut-point thresholds on “positive” results, compare ampulla of Vater and pancreas adenocarcinomas, and provide additional experience with CK17 reactivity. Almost all neoplasms had extensive CK7 reactivity. The number of CK20positive cases decreased from 29 (45%; a...

Background: The innate immune system is our first line of defense against invading pathogens. Toll–like receptors (TLRs) have been identified as a key role in mediating the function of innate immune system which bridges the gap between innate and adaptive immunity. For example, TLR2 is able to act as a homodimer to recognize lipoteichoic acids of Gram-positive bacteria but as a heterodimer with...

CONTEXT Malignant melanoma commonly metastasizes to the small intestine where it can cause pain, bleeding, and obstruction. However, jaundice from metastatic melanoma is relatively uncommon. CASE REPORT A case of known malignant melanoma presenting as new onset obstructive jaundice as a result of a rarely reported metastasis to the ampulla of Vater. CONCLUSION Multidisciplinary management o...

A patient with pancreatic arteriovenous malformation who presented diagnostic and therapeutic difficulties is presented. The initial tests appeared to suggest inflammatory bowel disease, but the diagnosis was clinched by the finding of blood issuing from the ampulla of Vater. Repeated angiographic embolization did not obliterate the vascular malformation, and the symptoms eventually resolved af...

PATIENT Female, 45 FINAL DIAGNOSIS: Neuroendocrine tumor Symptoms: Abdominal pain Medication: - Clinical Procedure: - Specialty: Gastroenterology and Hepatology. OBJECTIVE Unusual setting of medical care. BACKGROUND Neuroendocrine tumor of the ampulla of Vater is extremely rare and is generally a low-grade endocrine cell tumor. The merits of radical vs. local resection remain uncertain. C...

Duodenal injury following blunt abdominal trauma is uncommon. The severity of injury can vary from an intramural haematoma to a duodenal rupture with associated transection of the pancreatic duct. A case of duodenal rupture with avulsion of the ampulla of Vater is presented and discussed.

Note: Tumor staging is separated by TNM classification (International Classification of Diseases, ICD). TNM classifications for carcinomas of the gallbladder, extrahepatic bile ducts and the ampulla of Vater. The histopathological classification of biliary tract carcinoma follows WHO classification: adenocarcinoma, adenosquamous carcinoma, squamous cell carcinoma, small cell carcinoma, adenoend...
