Laparoendoscopic Rendez Vous Versus Standard Two Stage Approach for the Management of Cholelithiasis/Choledocholithiasis

Overview

The purpose of the study is to assess whether combined intraoperative ERCP and CBD clearance with laparo-endoscopic rendez-vous during laparoscopic cholecystectomy (one stage approach) is or not superior to the standard practice of preoperative ERCP, sphincterotomy and CBD clearance followed by laparoscopic cholecystectomy (two stage approach) in patients with combined cholelithiasis and choledocholithiasis.

The ideal management of concomitant cholelithiasis and choledocholithiasis is not known yet. There are several options, including one-stage or two-stage approaches. The most commonly used practice is the two-stage management which consists of preoperative ERCP, sphincterotomy and CBD clearance followed by laparoscopic cholecystectomy. However, with this approach, a number of patients will be submitted to an unnecessary ERCP while some others will develop complications, mainly pancreatitis due to inadvertent pancreatic duct cannulation. Laparo-endoscopic rendez-vous methods have been described in order to obtain selective CBD cannulation and omit the risk of post-ERCP pancreatitis. In this procedure, during laparoscopic cholecystectomy, a wire is inserted through the cystic duct into the common bile duct, advanced into the duodenum where is found endoscopically, gripped with a snare and retrieved through the mouth. The a sphincterotome is inserted over the wire and elective CBD cannulation is obtained to be followed by sphincterotomy and CBD clearance intraoperatively. The method has been described by several authors in small to moderate case series, its safety has been proven and it appears that reduces both the length of hospital stay and the incidence of post-ERCP pancreatitis.However, it has not been popularized and has never been tested over the standard two-stage management. In our hospital, the standard approach for cholelithiasis and choledocholithiasis has been, as well, the two-stage (preop ERCP and sphincterotomy followed by laparoscopic cholecystectomy)approach. We initially assessed the feasibility and safety of the laparo-endoscopic rendez vous with a pilot study and now we intend to compare the two methods in a prospective randomized trial.
