    Abstract:
    OBJECTIVE: To compare the surgical outcomes of Kasai Portoenterostomy (PE) and investigate the learning curve of laparoscopic Kasai Portoenterostomy (Lap-PE). MATERIALS AND METHODS: Retrospective chart review of 80 cases of biliary atresia (type III) undergoing Lap-PE at Shenzhen Children's Hospital from January 2011 to June 2015, all of which were performed by the same surgical team. According to the operative sequences, the cases were equally divided into four phases (Phase I, II, III, and IV), which contain 20 cases in each. The age, weight, and gender, the volume of intraoperative blood loss, the postoperative clearance rate of bilirubin, the incidence of postoperative cholangitis, and the first and second year native liver survival rate were all reviewed. RESULTS: There was no significant difference among the four phases regarding age, weight at operation, and gender (P > .05). Statistical difference was observed with respect to operative time, the volume of intraoperative blood loss, the postoperative jaundice clearance, and the first and second year native liver survival rate among Phase III and IV compared to Phase I and II (P < .05), but showed no significant difference in neither the first two phases nor the latter two phases (P > .05). The incidence of postoperative cholangitis showed no significant variation among the four phases. CONCLUSION: A surgeon is able to become more experienced after performing approximately 40 laparoscopic Kasai Portoenterostomys.
