    Abstract:
    The long-term outcomes of branched-chain amino acid (BCAA) administration in patients undergoing hepatic resection remain unclear. The aim of this study is to assess the impact of oral supplementation with BCAA-enriched nutrients on postoperative quality of life (QOL) in patients undergoing liver resection. A prospective randomized clinical trial was conducted in 96 patients undergoing hepatic resection. Patients were randomly assigned to receive BCAA supplementation (AEN group, n = 48) or a conventional diet (control group, n = 48). Postoperative QOL and short-term outcomes were regularly and continuously evaluated in all patients using a short-form 36 (SF-36) health questionnaire and by measuring various clinical parameters. This study demonstrated a significant improvement in QOL after hepatectomy for liver neoplasm in the AEN group based on the same patients' preoperative SF-36 scores (P < 0.05). Perioperative BCAA supplementation preserved liver function and general patient health in the short term for AEN group patients compared to those not receiving the nutritional supplement. BCAA supplementation improved postoperative QOL after hepatic resection over the long term by restoring and maintaining nutritional status and whole-body kinetics. This study was registered at http://www.clinicaltrials.gov (registration number: NCT00945568).
