Systematic review and meta-analysis of minimally invasive techniques for the management of cholecysto-choledocholithiasis.

BACKGROUND: The optimal management of patients with symptomatic gallstones and possible or proven common bile duct (CBD) stones and gallstones is still evolving. Today a number of options exist: preoperative endoscopic retrograde cholangiopancreatography (pre-op ERCP), laparoscopic cholecystectomy (LC) combined with intraoperative endoscopic sphincterotomy (IOES), laparoscopic common bile duct exploration (LCBDE) and postoperative ERCP (post-op ERCP). This meta-analysis was done to compare these management options and determine if any single option was clearly superior.

METHODS: A systematic search was conducted using several electronic databases. The search revealed 15 randomized controlled trials (RCTs). Six comparing pre-op ERCP with LCBDE, five comparing pre-op ERCP with IOES, two comparing IOES with LCBDE and two comparing post-op ERCP with LCBDE, comprising a total of 1992 patients.

RESULTS: The pre-op ERCP group had a significantly higher incidence of ERCP related complications (odds ratio: 2.40, 95% confidence interval: 1.21-4.75).

CONCLUSIONS: The evidence provided by this meta-analysis suggests that both of these approaches would appear comparable. To fully address which would be the better approach would require an RCT as discussed above.
