Core Tip

Core Tip: Ectopic pancreas at the ampulla of Vater (EPAV) is an extremely rare condition, usually mimicking malignancy and presents as abdominal pain and obstructive jaundice. This rare entity should be included in the differential diagnosis of subepithelial ampullary lesions. The diagnosis of EPAV remains very challenging despite several endoscopic and radiological advances. The diagnosis is usually based on morbid surgical interventions such as pancreaticoduodenectomy/ampullectomy or autopsy. Endoscopic en bloc resection of the papilla with endoscopic snare papillectomy may play a vital role as a diagnostic and therapeutic option for preoperative histological diagnosis and staging to avoid morbid surgical procedures.
