A case of live round worm in common bile duct stent of a post - endoscopic retrograde cholangiopancreatogram patient
Roundworm infestation is common in the human intestine. Sometimes it also enters the biliary system and may cause acute cholangitis, obstructive jaundice, stone formation, acute biliary colic and cholecystitis. Rarely, ascariasis of common bile duct (CBD) can result after endoscopic retrograde cholangiopancreatogram (ERCP) done for CBD stone extraction. We present one such unusual case of roundworm in CBD stent in the post‑ERCP period.
