Lemmel syndrome: a rare cause of obstructive jaundice (case report)

Abstract

Obstructive jaundice through periampullary duodenal diverticulum (PAD), without gallstones or neoplasms, was first described by Lemmel in 1934 as Lemmel syndrome. PAD can be diagnosed incidentally or suspected in patients with obstructive jaundice and nonspecific abdominal pain. It is a rare and benign condition that can be misdiagnosed as malignancy. Ignoring this, can cause morbidity and mortality. Definite diagnosis is made by Endoscopic Retrograde Cholangiopancreatography (ERCP). An accurate diagnosis is very important to ensure patient management and to avoid complications of delayed care. We present a case who coincidentally was diagnosed with PAD and thus obstructive jaundice.
