Objectives: Laparoscopic Kasai portoenterostomy (LKPE) has been shown to be a safe and feasible procedure in patients with biliary atresia (BA). The purpose of this study was to investigate the efficacy of modified LKPE (MLKPE) in the treatment of BA. Methods: Data of 58 BA patients undertaken MLPKE from July 2014 to December 2015 were retrospectively analyzed (group B), and compared with that of 43 BA patients received open Kasai portoenterostomy (OKPE) during the same period (group C). In addition, 195 BA patients who had undergone LKPE during May 2009 to June 2014 were also included (group A). Results: All 296 patients enrolled in this study were non-syndromic type III BA. Compared with group A, group B had shorter operative time (ORT) (P < 0.01) and fewer intraoperative blood transfusion (IOBT) (P < 0.05). The conversion rate and cholangitis rate were also significantly lower in group B than that in group A (P < 0.05). The postoperative oral intake resumed (POOR), any postoperative complications (APOC), clearance of jaundice (CJ), 1-year and 3-year survival rate with native liver (SNL) were not significantly different between group A and group B (P > 0.05). The ORT, IOBT, POOR, APOC, CJ, 1-year and 3-year SNL in group B were much better than that of group C (P < 0.05). Conclusion: The MLKPE was associated with good perioperative with ORT, IOBT, POOR, and APOC. The short-term outcomes in MLKPE were no worse than that of OKPE and LKPE. MLKPE can be regarded as a treatment option for BA. [ABSTRACT FROM AUTHOR]

Background: Although open portoenterostomy (OPE) is considered the standard treatment for biliary atresia (BA), laparoscopic portoenterostomy (LPE) is conducted and reported by many investigators. Data on the safety and efficacy of LPE remain controversial. The aim of this meta-analysis is to compare the safety and efficacy of LPE and OPE for the treatment of BA.Methods: Three electronic databases were searched: PubMed, Embase, and the Cochrane Library. The eligible studies were limited to those published in English. The following keywords were used: "biliary atresia," "laparoscopic portoenterostomy," "Kasai portoenterostomy," "open portoenterostomy," "surgery," and "treatment."Results: Nine studies, including 434 patients, were analyzed. The operative time of LPE was significantly longer than that of OPE (MD = 40.55 min, 95% CI 4.83-76.27 min, P = 0.03). There was no significant difference between the two groups in terms of the time of hospital stay, the volume of intraoperative blood loss, or the rates of cholangitis, early clearance of jaundice or two-year survival with the native liver. The subgroup analyses revealed that the rate of early clearance of jaundice in the LPE group was significantly higher than that in the OPE group in studies published after 2016 (95% CI 1.04-1.75; P = 0.02).Conclusions: The present meta-analysis provides evidence that LPE is a feasible option for patients with BA. LPE should be revaluated by further studies and longer follow-up. [ABSTRACT FROM AUTHOR]
