Partial obstruction of sphincter of Oddi, secondary to Ascaris, is a clinically descried entity. Herewith we describe our institutional experience in a 46-year old gentleman who presented with obstructive jaundice and recurrent cholangitis. On surgical exploration of the common bile duct (CBD), a round worm was found obstructing the proximal lumen and on extraction of the worm, the patient was rendered symptom free postoperatively. He remained asymptomatic after three weeks and on further follow up. Here we describe our case.
