BACKGROUND: This study was designed to compare perioperative and oncologic outcomes between minimally invasive liver resection (MILR) and conventional open liver resection (COLR) for hepatocellular carcinoma (HCC) using a propensity-score matched analysis. METHODS: Ninety-nine patients who received MILR were matched with 198 patients treated with COLR out of 928 patients with HCC who received curative liver resection from 2002 to 2012. A multivariable logistic model based on factors related to the patient, tumor, and surgical procedure was used to estimate a propensity score. RESULTS: The MILR group experienced significantly less intraoperative blood loss (mean: 389.55 vs 580.66 mL: P = 0.008), lower complication rates (13.1% vs 24.7%: P = 0.020), and a shorter length of hospital stay (mean: 8.40 vs 13.39 days: P < 0.001). The two groups did not differ significantly in disease-free (P = 0.701) or overall survival (P = 0.086). CONCLUSIONS: MILR produced better perioperative and comparable oncologic outcomes than COLR for HCC. Copyright (c) 2015 John Wiley & Sons, Ltd.
