Management of common bile duct stones by laparoscopic cholecystectomy and endoscopic sphincterotomy: pre-, per- or postoperative sphincterotomy?

Background/aims: The aim of this study was to evaluate the treatment of common bile duct stones (CBDS) by endoscopic sphincterotomy (ES) and laparoscopic cholecystectomy (LC), ES being performed either pre-, per- or postoperatively.

Methods: Between January 1990 and June 1997, 386 patients with a median age of 60 (range 18-92) years were treated for suspected or confirmed CBDS. The CBDS were uncomplicated in 264 cases (70%) but associated with a complication in 122 cases (30%), namely, cholangitis (69 cases) or acute pancreatitis (53 cases). ES combined with LC was carried out in 233 cases (60%): ES was preoperative (sequential treatment in two stages) in 197 cases (51%); peroperative in 30 cases (7%), or postoperative in 6 cases (2%). Laparoscopic extraction was performed in 58 cases (15%) and conventional surgery in 82 cases (21%).

Results: With respect to sequential treatment, endoscopic retrograde cholangiography showed the presence of CBDS in 117 cases (60%) and preoperative ES allowed the release of the CBDS in 82% of these cases. The complication rate of sequential treatment was 8% (15 cases) after ES and 7% (13 cases) after LC, with 1 death (0.5%). A peroperative ES performed after LC enabled evacuation of the CBDS in 28 cases (93%) without any complications or mortality. Postoperative ES was successful in 100% of cases with residual lithiasis in 16% (1 case) and a complication rate of 16% (1 case).

Conclusion: Along with conventional surgery and laparoscopic extraction, ES combined with LC represents an effective alternative in the management of CBDS. Since it can be performed peroperatively, it allows a one-stage, minimally invasive treatment of most uncomplicated CBDS.
