We describe a single operative treatment whereby, following laparoscopic cholecystectomy, laparoscopic CBD exploration via choledochotomy allowed retrieval of the retained basket and confirmation of duct clearance with choledochoscopy. We have shown the approach to be both feasible and safe and, where surgical expertise permits, can reduce the risk of further treatment sessions to manage residual common bile duct stones or debris.
Careful choledochoscopy was done to identify the right and left segmental ducts and ensure the absence of intrahepatic stones.
Ultrasound scan, CT (Figure 1), MRI (Figure 2), MRCP, ERCP, intraoperative cholangiography, and choledochoscopy all have been described in the literature for the preoperative work-up of BCA [42-46].
Biliary tree clearance was achieved either prior to surgery by ERCP or per-operatively by choledochoscopy. All patients underwent laparoscopic cholecystectomy in standard way using four ports.
But routine application of choledochoscopy or completion cholangiography plus the availability of ERCP for stone extraction have reduced those indications of T-tube.
