Obscure gastrointestinal bleeding: case report of ectopic pancreas associated with small bowel angiodysplasia.

Obscure gastrointestinal bleeding (OGIB) is defined as bleeding not identified by standard endoscopy or colonoscopy and requires advanced diagnostic modalities. Ectopic pancreas is a rare congenital anomaly, usually asymptomatic but occasionally presenting with abdominal pain, obstruction, or gastrointestinal bleeding. We report a 23-year-old female admitted with melena and hemodynamic instability. Initial investigations were inconclusive. Persistent bleeding led to urgent laparotomy, which revealed jejunal nodular lesions. Segmental enterectomy was performed, with favorable recovery. Histology confirmed ectopic pancreatic tissue associated with jejunal angiodysplasia. This rare association highlights diagnostic and therapeutic challenges of OGIB and the importance of surgical intervention in unstable patients.
