A RETROSPECTIVE STUDY ON THE SIGNIFICANCE AND USEFULNESS OF PREOPERATIVE AND INTRAOPERATIVE CHOLANGIOGRAPHY IN LAPAROSCOPIC CHOLECYSTECTOMY

Abstract

We retrospectively studied 262 cases undergoing laparoscopic cholecystectomy (LC) at the hospital during the past 37 months to elucidate the significance and usefullness of preoperative and intraoperative cholangiography. Preoperative cholangiography was performed in all 262 cases and intraoperative cholangiography for selected cases which demanded it (17.8%). We had two postoperative complications including bleeding and mechanical ileus. No complication caused by intraoperative biliary injury and residual stones was encountered. Mean operative time was significantly longer in intraoperative cholangiography proup (109.4min) than in control group (83.9min) (p<0.0001). Nine cases were converted to conventional open cholecystectomy. The converting rate in preoperative GB negative group (15.3%) was significantly higher than in GB positive group (1.8%) (p<0.005). We think that there is no necessity to conduct the intraoperative cholangiography for all patiensand preoperative cholangiogphy is useful for assessment of the difficulty in LC.
