Intraoperative cholangiography was successfully performed in 98% of 300 consecutive laparoscopic cholecystectomies, including 290 chronic, 44 acute, 33 fibrotic, 16 gangrenous, and 17 hydropsed cases. Unsuspected common duct stones were identified in 16 patients (4%). The presence of two surgeons and the ability of routine cholangiography to clarify the biliary anatomy produced excellent results with no injuries to the common duct in this series.
