SummaryThe indications and best technique for peroperative cholangiography during laparoscopic cholecystectomy remain unclear, but the operation has been associated with an increased use of preoperative endoscopic retrograde cholangiography. Cystic duct cholangiography, particularly in the hands of the trainee, can be time consuming, and bile duct injury may be caused by attempts to cannulate the cystic duct. This study analyses 113 consecutive patients undergoing peroperative cholangiography through the gallbladder, or cholecystocholangiography. It was successful in 92 (81.4%) patients, the procedure adding less than 10 min to the operating time. There were no cholangiogram-related complications. Common anatomical variations included both short and particularly wide cystic ducts. This information helps to minimize the risk of damage to the common bile duct. This study demonstrates that cholecystocholangiography is a safe, simple, and effective alternative to cystic duct cholangiography with virtually no “learning curve.” It provides a “road-map” of biliary anatomy and identifies common bile duct stones prior to the commencement of dissection. Unsuccessful cholecystocholangiography does not preclude the use of cystic duct cholangiography later in the operation. Difficult anatomy is demonstrated prior to dissection. When unsuspected bile duct calculi necessitate open exploration, further laparoscopic dissection is avoided.
