An Unwanted Guest in the Biliary Tract: A Case Report

Ascariasis is a frequent human gastrointestinal tract helminthic disease caused by Ascaris lumbricoide. It usually stays in the intestinal lumen and occasionally migrates into the biliary tract through ampulla of Vater. Biliary ascariasis is a critical complication of intestinal ascariasis with life-threatening manifestations. We report a case of a-38 year-old lady who presented with colicky type epigastric pain radiating to back with diffuse tenderness over abdomen on examination. Ultrasonography abdomen showed linear echogenic structure in common bile duct. Biliary ascariasis was noted on Endoscopic Retrograde Cholangio Pancreaticography following which extraction was done. Our report highlights the varied clinical features of biliary ascariasis.
