Abstract

Hem-o-lok clip migration into the common bile duct (CBD) and subsequent stone formation is a rare, late complication following laparoscopic common bile duct exploration (LCBDE). The clinical presentation often mimics that of primary CBD stones, including biliary colic and cholangitis. We report the case of a 79-year-old female patient diagnosed with a secondary CBD stone formed around a migrated surgical clip just four months after LCBDE. The patient was admitted with progressively increasing right upper quadrant (RUQ) pain. Imaging (MRI) confirmed biliary duct dilation and an impacted stone in the distal CBD. The patient was successfully treated with Endoscopic Retrograde Cholangiopancreatography (ERCP) with Spyglass assistance. ERCP successfully retrieved a large calculus containing two Hem-o-lok clips. Clip migration leading to stone formation can occur at any time, but is commonly reported within two years post-surgery. Hem-o-lok migration causing CBD lithiasis is a complication that warrants close surveillance; most cases necessitate endoscopic or surgical intervention for management.
