Abstract
BACKGROUND: Although laparoscopic minor liver resections (LLR) of posterosuperior (PS) segments are technically challenging, several expert centers are increasingly performing this procedure. In the present study, we introduced novel techniques, including the rubber band traction method and positional changes, and compared surgical outcomes of LLR for hepatocellular carcinoma (HCC) located in PS segments with open minor liver resection (OLR). METHODS: From January 2008 to August 2019, 113 patients underwent laparoscopic (n = 55) or open (n = 58) minor liver resections for single small HCCs (<5 cm) located in PS segments. Propensity score matching in a 1:1 ratio was conducted to minimize preoperative selection bias, and surgical outcomes were compared between the two groups. RESULTS: There was no intraoperative mortality or reoperation in either group. One conversion to open surgery was necessary due to severe post-operative adhesions. The matched LLR group compared to OLR had significantly shorter operative time (215.16 vs. 251.41 min, P = 0.025), lesser blood loss (218.11 vs. 358.92 mL, P = 0.046), lower complication rate (8.1% vs. 29.7%, P = 0.018), and shorter hospital stay (7.03 vs. 11.78 days, P = 0.001). Intraoperative transfusion, R0 resection, resection margin, 5-year disease-free survival and 5-year overall survival were comparable. CONCLUSION: Our standardized LLR provided improved short-term outcomes and similar long-term outcomes, when compared with OLR. With advanced techniques and accumulated surgical experience, LLR can be the first option for HCC in PS segments at expert centers.
