[Retained gallstones with reference to their nonsurgical treatment]
Abstract:
In a series of 1122 cholecystectomies we observed 15 cases of retained bile duct stones. Early postoperative diagnosis was achieved by T-drain-cholangiography. The application of T-drains was afflicted with a morbidity rate of 3.5%. For treatment we performed 2 relaparotomies, 3 percutaneous extractions, 5 endoscopic extractions, 1 lysis and 1 extracorporal shock-wave-lithotripsy. Using nonsurgical methods there are only few indications for open explorative choledochotomy.
