The laparoscopic approach to liver resection has experienced exponential growth in recent years; however, its application is still under debate and objective, evidence-based guidelines for its safe future progression are needed.
The aim of this study was to perform a systematic review and meta-analysis comparing the short- and long-term outcomes of laparoscopic and open liver resections for hepatocellular carcinoma (HCC).
To identify all the comparative manuscripts reporting on laparoscopic and open liver resection for HCC, all published English-language studies with more than 10 cases were screened. In addition to the primary meta-analysis, four specific subgroup analyses were performed on patients with Child–Pugh A cirrhosis, resections for solitary tumors, and those undergoing minor and major resections. The quality of the studies was assessed using the Scottish Intercollegiate Guidelines Network (SIGN) methodology and the Newcastle–Ottawa Scale.
From the initial 361 manuscripts, 28 were included in the meta-analysis. Five of these 28 manuscripts were specific to patients with Child–Pugh A cirrhosis (321 cases), 11 focused on solitary tumors (1003 cases), 16 focused on minor resections (1286 cases), and 3 focused on major resections (164 cases). Three manuscripts compared 1079 cases but could not be assigned to any of the above subanalyses. In general terms, short-term outcomes were favorable when using a laparoscopic approach, especially in minor resections. The only advantage seen with an open approach was reduced operative time during major liver resections. No differences in long-term outcomes were observed between the approaches.
Laparoscopic liver resection for HCC is feasible and offers improved short-term outcomes, with comparable long-term outcomes as the open approach.
