JUST BECAUSE IT IS RARE DOESN’T MEAN IT IS IMPLAUSIBLE: LEMMEL’S SYNDROME A CASE SERIES

Abstract

Lemmel’s syndrome is a rare pancreaticobiliary complication of duodenal diverticula. It occurs when a duodenal diverticulum causes obstructive\njaundice due to a mechanical obstruction of the common bile duct. Other mechanisms like sphincter of Oddi dysfunction can also play a role in\npathophysiology. We report three cases of Lemmel’s syndrome where liver biochemistry showed obstructive jaundice; but subsequent MRCP\nshowed a massive periampullary diverticulum causing biliary obstruction. Early detection and intervention can prevent needless additional\ninvestigations and complications due to obstruction.
