Abstract

Background
Incisional hernia (IH) is a common complication after liver transplantation (LT) with an incidence of 5% to 46%. The purpose of this retrospective study was to evaluate the risk factors for IH development after LT in the era of mammalian target of rapamycin inhibitors usage (mTORi).
Methods
Data on patients who underwent LT at Seoul National University Hospital between 2015 and 2021 were retrospec-tively reviewed. They were divided into two groups according to occurrence of IH during their postoperative course; an IH group and a non-IH group.
Results
There were 646 patients during the study period. Among those, 24 (3.7%) patients experienced IH. The mean body mass index was significantly higher in the IH group compared to non-IH group (25.3 vs. 23.9; P=0.024). There were no sig-nificant differences in age, gender, model for end-stage liver disease score, operation time, usage of mTORi between the two groups.
Conclusions
Attention should be paid to IH in obese patients.
