Early versus delayed laparoscopic cholecystectomy after endoscopic retrograde cholangiopancreatography: A meta-analysis.

PURPOSES

Patients with cholecysto- and choledocholithiasis usually undergo endoscopic retrograde cholangiopancreatography (ERCP)/-endoscopic sphincterotomy followed by laparoscopic cholecystectomy (LC). However, differences in the timing of LC after the ERCP may alter the post-operative outcomes. The aim of this study was to compare the effect of early (≤3 days) or delayed LC (>3 days) following ERCP on the post-operative outcomes.

METHODS

A comprehensive search of the 3 databases PubMed, EMBASE and the Cochrane Library was performed. Articles related to LC at different time-points after ERCP were retrieved. Dichotomous and continuous outcomes were analyzed by risk ratio (RR) and mean difference, and RevMan was used to analyze each group.

RESULTS

A total of 7 studies, including 5 randomized controlled studies and 2 retrospective studies, involved a total of 711 patients. There were 332 patients in early LC group and 379 in delayed LC group. The conversion rate was lower in the early LC group compared to the delayed LC group (RR 0.38, 95% confident interval 0.19 to 0.74, P = .005, I2 = 0%). Early LC resulted in a shorter operation time (RR -6.2, 95% CI -27.2 to -5.2, P = .004, I2 = 97%) and fewer complications (RR 0.48, 95% CI 0.29 to 0.79, P = .004, I2 = 17%). Subgroup analysis found that there were no significant differences in the conversion rate (RR 0.61, 95% CI 0.25 to 1.45, P = .26, I2 = 0%) or complications between the early LC group and the delayed group who underwent LC after 1 month.

CONCLUSION

Early LC after ERCP is the preferred treatment for patients with concurrent cholecysto- and choledocholithiasis due to improved clinical outcomes as compared to those who undergo delayed LC.
