Forest plot for successful duct clearance in patients with choledocholithiasis undergoing a laparoscopic transcystic or transcholedochal approach. Studies that had 100 per cent success in both arms18, 23 were not included in the analysis, so calculation of an odds ratio was not possible in the pooled analysis. LTCE, laparoscopic transcystic exploration; LCD, laparoscopic choledochotomy; nRCT, non‐randomized clinical trial. A random‐effects model was used for meta‐analysis. Odds ratios are shown with 95 per cent confidence intervals.
