Robot-assisted versus conventional laparoscopic major hepatectomies: Systematic review with meta-analysis.

Abstract

Major hepatectomy is still regarded as a technically demanding procedure for which minimally invasive surgery remains limited to selected cases in experienced centres and robotic platforms may provide some advantages over conventional laparoscopy in this setting. We aimed to combine and meta-analyse the available literature upon this topic. The PubMed, MEDLINE and Web of Science databases were appraised to find all available studies comparing robotic and laparoscopic major hepatectomies. According to a pre-established pattern preoperative settings, operative and postoperative outcomes were assessed. The meta-analysis was performed by using the Revman 5.3 software. A total of 485 patients from eight studies were included in the analysis. Robotic major hepatectomies showed a significantly lower conversion rate and estimated blood loss as compared to laparoscopic ones. Laparoscopic major hepatectomies patients experienced significant shorter postoperative hospitalisation. Robotic surgery appears as competent as conventional laparoscopy to perform major hepatectomies, with possible advantages on conversion rate and perioperative blood loss, despite slightly prolonged postoperative hospitalisation.
