[Intraoperative ultrasonography for common bile duct exploration during laparoscopic cholecystectomy].

The "Endomedix Laparoscan" and the "Leopard" and "Panther" intraoperative ultrasounds were successfully used for the detection of unsuspected common bile duct stones during laparoscopic cholecystectomy (LC). Out of 60 patients six had common bile duct (CBD) stones and in one patient sludge has been seen. In patients with CBD stones, four small calculi have been observed in one patient, despite negative intraoperative cholangiography (IC).
