Annular pancreas presenting as gastric outlet obstruction in adult: A rare case report

Abstract

Annular pancreas (AP) is a rare congenital anomaly where pancreatic tissue encircles the duodenum. While typically presenting in infancy, adult-onset AP is uncommon and often masquerades as other upper gastrointestinal pathologies, making it a diagnostic challenge. This report highlights an adult case of AP presenting with classic gastric outlet obstruction.
