title: Laparoscopic common bile duct exploration versus pre or post-operative ERCP for common bile duct stones in patients undergoing cholecystectomy: is there any difference?
abstract: A best evidence topic in surgery was written according to a structured protocol. The question addressed was: in patients with symptomatic gallstones and concomitant common bile duct (CBD) stones, is a single-stage surgical strategy (laparoscopic cholecystectomy (LC) with common bile duct exploration) preferable, or a two-stage procedure involving LC with pre or post-operative endoscopic retrograde cholangiography (ERCP)? Two hundred and six papers were found using the reported search, of which four presented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group, study type, relevant outcomes and results of these papers are tabulated. A recent large meta-analysis concluded no significant difference in the clinical effectiveness or complication rate of either strategy. Three recent smaller studies concurred with this conclusion; however each noted improved cost-effectiveness of the single-stage approach advocating its use as the superior strategy when local resources and expertise are available. We conclude that for patients with symptomatic gallstones and concomitant choledocholithiasis, a single-stage surgical procedure is equivalent to two-stage LC and ERCP in terms of clinical outcomes, is associated with a shorter overall hospital stay and may be more cost-effective. On this basis a single-stage procedure is recommended for management of symptomatic gallstones and choledocholithiasis where local resources and expertise permit.
