Comparison of LCBDE vs ERCP + LC for Choledocholithiasis

After removing the gallbladder, Laparoscopic common bile duct exploration (LCBDE) was performed by one fulltime attending in laparoscopy in a routine fashion. Access from the opening of the anterior wall of common bile duct or from the dilated cystic duct was acceptable, removed stone(s) and irrigated the duct followed by choledochoscope detection simultaneously. Cholangiograms were also can be a alternative method to obtain stone clearance. If needed, all fluoroscopy was performed by the principal author in the presence of and concurrence with the ERCP endoscopist. Once the LCBDE was completed, the incision of the bile duct was sewed intermittently by absorbed threads, or ligated cystic duct. T-tube was acceptable if needed.

Initially endoscopic retrograde cholangiopancreatography (ERCP) was performed by a fulltime attending and concurrence of the principal author in endoscopy. Patients randomized to ERCP+ LC group were scheduled to undergo the endoscopic procedure using fluoroscopy in the endoscopy center under moderate sedation (principally intravenous midazolam and meperidine) prior to the intended laparoscopy. Gastric intestinal atony during ERCP was routinely achieved using scopolamine butylbromide injection. Sphincterotomy (EST) and Endoscopic papillary balloon dilatation (EPBD) can be choose accordingly. The laparoscopic cholecystectomy was subsequently performed as soon as technically feasible following the ERCP in one month.
