Unsuspected choledocholithiasis first diagnosed at laparoscopic cholecystectomy: treatment by trans-cystic duct stenting and elective stent-guided sphincterotomy.

ABSTRACT

BACKGROUND: Despite advances in laparoscopic surgery, management of unsuspected choledocholithiasis diagnosed at laparoscopic cholecystectomy is controversial. We propose a simple maneuver of laparoscopic trans-cystic duct stenting of the papilla during cholecystectomy, followed by elective stent-guided sphincterotomy, as an expedient option. METHODS: We studied retrospectively 16 patients with choledocholithiasis first diagnosed in the course of laparoscopic cholecystectomy, treated with laparoscopic stenting of the papilla via the cystic duct using a short Cotton-Leung stent before completion of cholecystectomy. Elective stent-guided, needle-knife sphincterotomy and stone clearance was performed 2 to 3 weeks postoperatively. RESULTS: Of 16 patients attempted, the procedure failed in one due to an impacted stone that prevented passage of the guidewire. Stenting time was 13 +/- 5 minutes (n = 15). Two stented patients had no stones at endoscopic retrograde cholangiography. Thirteen patients had successful elective stent-guided sphincterotomy with stone clearance without complications. CONCLUSIONS: Laparoscopic biliary stenting combined with stent-guided sphincterotomy is a simple, safe, and cost-effective option for the management of uncomplicated choledocholithiasis.
