Selective cholangiography. Current role in laparoscopic cholecystectomy.

The initial 22-month experience with laparoscopic cholecystectomy in 400 patients employing an algorithm of selective cholangiographic evaluation is reported. Preoperative or postoperative endoscopic retrograde cholangiography was performed whenever stones were suspected clinically. Preoperative endoscopic retrograde cholangiography was performed in 44 patients (11%), in whom 14 (3.5%) had an endoscopic sphincterotomy with extraction of common bile duct stones. Intraoperative cholangiography was performed in only eight patients (2%) almost exclusively to acquire experience with the technique, and all cholangiograms were normal. Laparoscopic cholecystectomy was successfully completed in 96% of the patients. There were no deaths in this series, and major complications occurred in only 5% of patients. Two patients (0.5%) had a significant common bile duct injury that was recognized and successfully repaired at the initial operation. No late common bile duct strictures have been recognized. Six patients (1.5%) underwent postoperative endoscopic retrograde cholangiography for suspected common bile duct stones, with three patients requiring endoscopic sphincterotomy and stone extraction. This experience suggests that the use of preoperative and postoperative endoscopic retrograde cholangiography can be based on clinical presentation and laboratory evaluation and does not need to be performed routinely. Routine intraoperative cholangiography is not necessary in most patients undergoing laparoscopic cholecystectomy. The authors conclude that laparoscopic cholecystectomy can be performed safely with the selective use of cholangiography.
