Laparoscopic versus open major liver resection for hepatocellular carcinoma: A case-matched analysis of short- And long-term outcomes

Abstract

The feasibility and safety of laparoscopic major hepatectomy (LMH) are still uncertain. The purpose of the present study is to compare the short- and long-term outcomes of LMH with those of open major hepatectomy (OMH) for hepatocellular carcinoma (HCC). Between January 2012 and December 2018, a total of 26 patients received laparoscopic major hepatectomy in our center. To minimize any confounding factors, a 1:3 case-matched analysis was conducted based on the demographics and extent of liver resection. Data of demographics, perioperative outcomes, and long-term oncologic outcomes were reviewed. Intraoperative blood loss (P = 0.007) was significantly lower in the LMH group. In addition, the LMH group exhibited a lower overall complication rate (P = 0.039) and shorter postoperative hospital stay (P = 0.024). However, no statistically significant difference was found between LMH and OMH regarding operation time (P = 0.215) and operative cost (P = 0.860). Two laparoscopic cases were converted to open liver resection. In regard to long-term outcomes, there was no significant difference between LMH and OMH regarding disease-free survival (DFS) (P = 0.079) and overall survival (OS) (P = 0.172). LMH can be an effective and safe alternative to OMH for selected patients with liver cancer in short- and long-term outcomes.
