Laparoscopic versus open portoenterostomy for treatment of biliary atresia: a meta-analysis.

OBJECTIVE: Our goal was to compare laparoscopic portoenterostomy versus open portoenterostomy for the treatment of biliary atresia.

MATERIALS AND METHODS: Using the databases EMBASE, PubMed, and Cochrane, we carried out a thorough literature search up to 2022. Studies comparing laparoscopic and open surgery for the treatment of biliary atresia were included.

RESULTS: Twenty-three studies comparing laparoscopic portoenterostomy (LPE) (n = 689) and open portoenterostomy (OPE) (n = 818) were considered appropriate for meta-analysis. Age at surgery time was lower in the LPE group than OPE group (I2  = 84%), (WMD - 4.70, 95% CI - 9.14 to - 0.26; P = 0.04). Significantly decreased blood loss (I2  = 94%), (WMD - 17.85, 95% CI - 23.67 to - 12.02; P < 0.00001) and time to feed were found in the laparoscopic group (I2  = 97%), (WMD - 2.88, 95% CI - 4.71 to - 1.04; P = 0.002). Significantly decreased operative time was found in the open group (I2  = 85%), (WMD 32.52, 95% CI 15.65-49.39; P = 0.0002). Weight, transfusion rate, overall complication rate, cholangitis, time to drain removal, length of stay, jaundice clearance, and two-year transplant-free survival were not significantly different across the groups.

CONCLUSIONS: Laparoscopic portoenterostomy provides advantages regarding operative bleeding and the time to begin feeding. No differences in remain characteristics. Based on the data presented to us by this meta-analysis, LPE is not superior to OPE in terms of overall results.
