ARTICLE HIGHLIGHTS
Research background
The application of laparoscopic portoenterostomy (LapPE) as a treatment option for BA remains controversial.
Research motivation
Management after BA surgeries is complicated and requires a centralized procedure for consistency. Thus, it is considered important to perform a largescale assessment at a single facility with a centralized management procedure for adequate comparison in the outcomes between LapPE and OpenPE.
Research objectives
The aim of this study was to compare the outcomes of Lap-PE with those of laparotomy (Open-PE) at our single institution.
Research methods
The surgical outcomes of PE were retrospectively analyzed for patients with a non-correctable type of BA from 2003 to 2020.
Research results
Throughout the assessment period, 119 patients received PE for BA treatment, including 66 Open-PE and 53 Lap-PE cases. Although the operation duration was longer (medians: for Open-PE, 242 min; for Lap-PE, 341 min; P < 0.001), blood loss was considerably less (medians: for Open-PE, 52 mL; for Lap-PE, 24 mL; P < 0.001) in the Lap-PE group than in the Open-PE group. Native liver survival rates were > 80% for both groups for the first half year post surgery, followed by a gradual decrease with time; there were no statistically significant differences in the native liver survival rates for any durations assessed.
Research conclusions
Lap-PE could be a standard therapy for BA.
Research perspectives
The rate of complications did not differ significantly, but long-term survival rates may differ. Therefore, further studies with a larger study size, longterm follow-up, and thorough evaluations are warranted.
