A duodenal diverticula causing a Lemmel syndrome: A case report

Abstract

Introduction: Lemmel syndrome corresponds to cholestatic disease secondary to compression of the main bile duct by a periampullary duodenal diverticulum. \nCase Report: We report a new case of Lemmel syndrome, caused by a periampullary duodenal diverticulum compressing the bile ducts leading to cholestasis. Computed tomography and MRI allows diagnosis, eliminate pancreatic origin, and avoid heavy surgery. \nConclusion: The duodenal diverticulum is a rare entity, remains asymptomatic for a long time, often discovered by the stage of complications, CT and MRI make it possible to make the diagnosis and to propose an adequate treatment.
