[Laparoscopic transcystic biliary calculus extraction with Dormia basket].

We describe transcystic common bile duct (CBD) stone extraction using Dormia basket in patients with preoperatively unexpected CBD stones during laparoscopic cholecystectomy (LC). We perform intraoperative cholangiography (IOC) selectively. Stone extraction was successful five times and we converted to open procedure in one patient because of the size of the stone.
