Recurrent Cholangitis due to Hem-o-lok Clip Migration after Laparoscopic Common Bile Duct Exploration Treated with Endoscopic Retrograde Cholangiopancreatography

Clip migration into the common bile duct (CBD) is a rare complication of laparoscopic biliary surgery. We report a case of Hem-o-lok clip migration-induced CBD stone in a 66-year-old man who underwent laparoscopic cholecystectomy (LC) and laparoscopic common bile duct exploration (LCBDE) 4 years ago. The patient visited the emergency room for upper abdominal pain. CT scan revealed increased CBD diameter and multiple CBD stones. We performed endoscopic retrograde cholangiopancreatography for CBD stone extraction. Cholangiography revealed multiple suspected filling defects in the CBD; stones and unknown foreign body were removed using Basket. The foreign body found in the duodenum was a Hem-o-lok clip. When epigastric pain develops in a patient who has undergone LC and LCBDE, it is possible that biliary stone occurs due to clip migration.
