Routine laparoscopic cholangiography: a means of avoiding unnecessary endoscopic retrograde cholangiopancreatography.

Controversy exists between routine and selective on-table cholangiography during laparoscopic cholecystectomy. Endoscopic retrograde cholangiopancreatography (ERCP) has been suggested as first-line investigation in patients with suspected duct stones. We report a series of 154 on-table cholangiograms (OTC) and consider the requirements for ERCP according to historical and biochemical markers. A retrospective review of 154 consecutive patients undergoing laparoscopic cholecystectomy with OTC was performed. Historical and biochemical markers of duct stones were examined with respect to the necessity of ERCP. OTC was performed, with a 100% success rate, and took approximately 10 min. Eight (5.2%) of the patients had duct stones. Only one did not have preoperative indicators of duct stones. Sixty-six patients had preoperative markers suggesting the need for ERCP. According to the OTC findings, 59 (89.4%) of these patients would have undergone unnecessary ERCP. Routine laparoscopic OTC is advocated because it maintains expertise in the technique and avoids unnecessary ERCP with its attendant costs and complications.
