[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. Mild postoperative acute pancreatitis developed once. No other complication was detected. Procedures performed if CBD stone is detected intraoperatively are evaluated in the article, including indications and difficulties of the Dormia basket method. We suggest the introduction of the method as an alternative treatment for unexpected CBD stones during laparoscopic cholecystectomy.
