Laparoscopic Kasai portoenterostomy is advantageous over open Kasai portoenterostomy in subsequent liver transplantation



Native liver survival after laparoscopic Kasai portoenterostomy (Lap-PE) for biliary atresia (BA) is controversial. We examined whether a jaundice-free native liver survival rate is comparable between conventional Kasai portoenterostomy (Open-PE) and Lap-PE. Then, the impact of the two types of PE on subsequent living-donor liver transplantation (LTx) was addressed in this study.


The jaundice-free rate in 1- and 2-year-old patients who underwent Open-PE and Lap-PE from January 2006 to December 2017 was investigated. Additionally, perioperative data (duration from the start of surgery to the completion of hepatectomy and others) of patients aged 2 years or younger who underwent LTx after either Open-PE or Lap-PE from 2006 to 2017 were evaluated.


Thirty-one (67%) out of 46 Open-PE patients and 23 (77%) out of 30 Lap-PE patients showed native liver survival with jaundice-free status at 1 year of age (p = 0.384); 29 (63%) out of 46 Open-PE patients and 19 (70%) out of 27 Lap-PE patients showed native liver survival with jaundice-free status at 2 years of age (p = 0.524); there were no significant differences. Additionally, there were 37 LTx cases after PE within 2 years of birth, including 29 Open-PE and 8 Lap-PE cases. The patients in the Lap-PE group had fewer adhesions and significantly shorter durations of surgery up to the completion of the recipient’s hepatectomy and durations of post-LTx hospital stay compared to the Open-PE group. There were no differences in blood loss or duration of stay in intensive care unit between the Lap-PE and Open-PE groups.


Jaundice-free native liver survival rate has been comparable between Open-PE and Lap-PE. Lap-PE resulted in fewer adhesions, contributing to better outcomes of subsequent LTx compared to Open-PE.
