Signet ring cell carcinoma (SRCC) is a rare lesion in the gastrointestinal tract. Further, the condition is very uncommon at the ampulla of Vater. A majority of the reported cases are typical, gland-forming adenocarcinomas. In our case, a patient aged 59 years, was diagnosed as a case of peri-ampullary carcinoma based on physical exam findings and imaging. Ultrasonography (USG) abdomen and magnetic resonance cholangiopancreatography (MRCP) revealed an enlarged common bile duct (CBD) and there was a presence of stricture at the terminal CBD. Endoscopic retrograde cholangiopancreatography (ERCP) showed growth at the ampulla of Vater. An endoscopic ultrasound guided needle core biopsy was obtained. Histopathological examination revealed the case as SRCC at the ampulla of Vater. We present this as an uncommon case of SRCC at the ampulla of Vater.

Introduction: Gastrointestinal stromal tumors (GIST), which occur anywhere in the gastrointestinal (GI) tract, typically occur in the stomach and small intestine but rarely in the duodenum. We present a case report wherein a descending duodenal GIST was treated with a limited, minimally invasive surgery after endoscopic nasobiliary drainage (ENBD) insertion.
Presentation Of Case: A 67-year-old woman visited our hospital with an incidentally discovered duodenal tumor.

The presence of high tumor budding in colorectal carcinomas is a significant pathological feature indicative of a high potential for lymph node metastasis. Our aim was to investigate the prognostic impact of tumor budding in ampullary carcinomas. We conducted a cohort of 101 consecutive ampullary carcinoma resections to evaluate tumor budding, macroscopic and microscopic subtypes, lymphatic/vascular/perineural invasions, and other histopathological parameters.

Unlabelled: Pancreatoduodenectomy represents the only curative alternative in patients with periampullary tumors, currently with acceptable morbidity and mortality rates. However, there is little evidence in octogenarian patients.
Aim: To describe the experience of octogenarian patients undergoing pancreatoduodenectomy for tumors of the periampullary area at the Hospital Clínico de la Pontificia Universidad Católica de Chile.
Stuck in the Sump: A Rare Complication of Biliary Surgery.

December 2024
Internal Medicine, Western Michigan University Homer Stryker M.D. School of Medicine, Kalamazoo, USA.
Sump syndrome is a rare complication of biliary surgery that is now rarely seen in the era of Endoscopic Retrograde Cholangiopancreatography (ERCP). It occurs when the distal common bile duct becomes obstructed between an anastomosis from a choledochoduodenostomy (CDD) and the ampulla of Vater, forming a sump that accumulates debris. Sump syndrome should be considered as a diagnosis in patients who present with cholangitis or pancreatitis and any history of biliary diversion, regardless of the time of presentation.
