    Abstract:
    One hundred sixty-five operative cholangiograms were attempted in 364 patients who underwent laparoscopic cholecystectomy (45%). Laparoscopic cholangiography was successful in 150 of 165 attempts (91%). Eighty-nine per cent of studies were normal (134/150) and 11% were abnormal (16/150). All 134 patients with normal cholangiograms remained asymptomatic (false-negative rate, 0%). False-positive studies occurred in 3 of 150 (2%) total cholangiograms and 3 of 12 (25%) abnormal cholangiograms consistent with choledocholithiasis. A total of 16 of 364 patients had proven common bile duct stones (4.4%). Eight of the sixteen stones were removed by preoperative endoscopic retrograde cholangiopancreatography/sphincterotomy. Five of sixteen stones were found at cholangiography, four of which were unsuspected (4/150, 2.6%). Retained common duct stones were found in 3 of 214 patients not undergoing cholangiography (1.4%). No complications or deaths occurred that were due to cholangiography. One biliary injury occurred (1/364, 0.3%), in a patient with aberrant anatomy who did not undergo cholangiography. Laparoscopic cholangiography is a safe technique with a success rate greater than 90%. Routine cholangiography is presently recommended for prevention of biliary injury, detection of stones in the cystic and common ducts, and for training purposes, especially during the learning phase of laparoscopic cholecystectomy.
