Short‐ and long‐term outcomes of laparoscopic versus open repeat liver resection for hepatocellular carcinoma: A multicenter study

Objective This multicenter study aimed to compare the short‐ and long‐term outcomes of laparoscopic (LRLR) versus open repeat liver resection (ORLR) for recurrent hepatocellular carcinoma (HCC) using propensity score matching (PSM). Despite the expanding indications for laparoscopic liver resection, limited data regarding the outcomes of LRLR have previously been reported. Methods This study included patients who underwent repeat liver resection for recurrent HCC. Patients were divided into the LRLR and ORLR groups, and their short‐ and long‐term outcomes were compared via PSM. Results There were 256 and 130 patients in the ORLR and LRLR groups, respectively. After PSM, 64 patients were included in each group. Intraoperative blood loss was significantly less in LRLR than in ORLR (56 vs 208 ml, P
