Cholecystectomy clip-induced biliary stone: Case report and literature review

Abstract

Abstract Migration of cholecystectomy surgical clip into the common bile duct with subsequent stone formation is a rare phenomenon, one which may lead to complications including obstruction, pain, nausea, vomiting and fever. The mechanism of migration is largely unknown but may result from a combination of factors including necrosis, intra-abdominal pressure or poor surgical technique with migrated clip serving as a nidus for stone formation. We present a 55-year-old woman with clip-induced stone impacted at the distal common bile duct 12 years post-cholecystectomy and a review of the literature related to cholecystectomy clip stone formation. In addition, we reviewed relevant English language case reports and literature reviews by searching PubMed using search terms ‘stone’, ‘clip’, ‘cholecystectomy’ and ‘biliary’. There was no limit to the date of publication. Our study found 68 unduplicated cases of clip-induced stones which had a wide range of onset and presenting systems. Further research is needed to identify risk factors, methods of prevention and benefits of early detection screening.
