Technique and results of routine dynamic cholangiography during 528 consecutive laparoscopic cholecystectomies

With the advent of laparoscopic cholecystectomy a trend toward more extensive preoperative diagnostic study of the biliary tree by intravenous cholangiography or ERCP has been observed. However, both exams have technical limitations and are not without risk. We report our experience with 500 consecutive routine dynamic intraoperative cholangiographies during laparoscopic cholecystectomy, 97% of which were successful. No lesions from cholangiography were observed. In ten patients clips on the cystic artery appeared on intraoperative cholangiogram to be too close to the hepatic duct and were removed. Anomalies of surgical importance were discovered in 11 patients (2.3%). Unsuspected stones were found in 18 cases (3.7%) and suspected stones confirmed in 12 (2.4%). In our experience routine dynamic intraoperative cholangiography provided important information in 51 cases out of 500 (10.2%). We conclude that routine dynamic intraoperative cholangiography is extremely useful for safer laparoscopic cholecystectomy and cost containment. © 1994 Springer-Verlag New York Inc.
