Endoscopic retrograde cholangiopancreatography (ERCP) is clearly a useful adjunct in the management of patients undergoing laparoscopic cholecystectomy who have common bile duct stones. Whether endoscopic sphincterotomy plus laparoscopic cholecystectomy is superior to traditional open cholecystectomy and bile duct exploration is a question which remains to be answered by prospective, randomized trials. The immense popularity of laparoscopic cholecystectomy may prohibit such a study in the USA. In expert hands, endoscopic stone extraction is usually successful, so ERCP can be deferred until after cholecystectomy unless there is serious suspicion of a duct stone preoperatively. Actual clinical practice will depend, however, on the skill of the surgeon, the skill of the endoscopist, and the commitment to removing the gallbladder laparoscopically. It would seem prudent for surgeons to continue to direct their energy toward conquering the common bile duct via the laparoscope, and leave ERCP and stone extraction in the realm of the endoscopist who has been extensively trained in this difficult technique. Proficiency at ERCP, sphincterotomy and stone extraction requires considerable training, and the procedure should not be attempted by individuals who have performed fewer than 100 ERCPs and 25 individually supervised sphincterotomies, according to the ASGE Standards of Training, 1992. As experience with video endoscopic surgery increases and technology improves, it will become possible to remove most duct stones at the time of cholecystectomy, thus obviating the need for endoscopic sphincterotomy. In addition, ERCP should be regarded as the treatment of choice for postoperative cystic duct stump leaks. Studies have shown that any type of biliary decompression, i.e. sphincterotomy, stents or nasobiliary catheters, will be successful. The authors recommend that, in the absence of duct stones, stenting or nasobiliary catheters be used as they are less invasive. Bile duct leaks may also be managed endoscopically, but success depends on the individual characteristics of the duct injury. The decision to manage late onset strictures endoscopically should be individualized, and consideration of local endoscopic expertise, operative risk, interval between surgery and stricture, and the patient's wishes should be made.
