BACKGROUND The importance of nutritional support in posttransplant patients is known and the advantages of oral feeding over parenteral feeding has been accepted widely, therefore the need of starting for oral feeding in early postoperative period has emerged. However, there are few studies about the difference of surgical outcomes according to the starting point of oral feeding. METHODS We enrolled 117 cases that underwent living donor liver transplantation since 2008 and divided them into two groups according to the starting point of oral feeding after surgery (within 48hrs vs. after 72hrs), and reviewed surgical outcomes and perioperative morbidities retrospectively. RESULTS In this study, 50 patients had early oral feeding (mean time 22.9 h) and 67 had late oral feeding (mean time 82.3 h). Both groups were comparable in terms of demographics and operative details. Our results showed shorter hospital stay of ICU (4.9 vs. 6.8 day, p=0.00) and lower incidence of postoperative medical complications (20.0 vs. 52.2%, p=0.00) in the early feeding group than the late feeding group. Median survival time was 23.3±14.1 months in the early feeding group and there was no statistical difference in 1-, 3-, and 5-year survivals between two groups. CONCLUSIONS The early oral feeding within 48hrs was associated with early postoperative recovery and reduced postoperative morbidities though it had no influence on survival rates. Therefore this retrospective study supports that the starting of early oral feeding within 48hrs should be considered in liver transplantation patients.
