Laparoscopic endobiliary stenting as an adjunct to common bile duct exploration

Background: The management of common bile duct stones (CBDS) in the era of operative laparoscopy is evolving. Several minimally invasive techniques to remove CBDS have been described, including preoperative endoscopic retrograde cholangiopancreatography (ERCP), postoperative ERCP, lithotripsy, laparoscopic transcystic common bile duct exploration, and laparoscopic choledochotomy with common bile duct exploration (CBDE). Because of the risks and limitations of these procedures, we utilize laparoscopically placed endobiliary stents as an adjunct to CBDE. Methods: Sixteen patients underwent laparoscopic common bile duct exploration (LCBDE) by either choledochotomy or the transcystic technique with placement of endobiliary stents. These patients were identified during laparoscopic cholecystectomy as having occult choledocholithiasis, using routine dynamic intraoperative cholangiography. Results: CBDS were successfully removed in all patients as demonstrated by completion cholangiography and intraoperative choledochoscopy. Eighty percent of patients were discharged the following day; the first three patients in this series were observed for 48 h prior to discharge. No patient required T-tube placement and closed suction drains were removed the morning after surgery. Stents were removed endoscopically at 1 month. Six- to 30-month follow-up demonstrates no complications to date. Conclusions: Laparoscopic endobiliary stenting reduces operative morbidity, eliminates the complications of T-tubes, and allows patients to return to unrestricted activity quickly. We recommend laparoscopically placed endobiliary stents in patients undergoing LCBDE.
