Clip-choledocholithiasis: a case of migrated surgical clip causing choledocholithiasis

Post-cholecystectomy clip migration is a rare but significant complication of laparoscopic cholecystectomy that can manifest years after the initial surgery. We report the case of a 56-year-old female who presented with chronic upper abdominal pain, nausea, and vomiting eight years following laparoscopic cholecystectomy. Laboratory investigations demonstrated markedly elevated liver enzyme levels, and imaging studies revealed a stone in the common bile duct. Endoscopic retrograde cholangiopancreatography identified a surgical clip embedded within the stone, serving as a nidus for stone formation. Successful treatment was achieved through biliary sphincterotomy and stone retrieval, resulting in complete symptomatic relief and normalization of liver function tests. This case highlights the importance of considering clip migration as a potential etiology in post-cholecystectomy patients presenting with unexplained biliary symptoms, even many years after the initial surgical procedure.
