Robotic versus open liver resections: A case-matched comparison

Abstract

Background: Most hepatic resections are currently performed using an open approach. Robotic surgery might enable the transition of these procedures to minimally invasive surgery.

Methods: Pre-, peri- and post-operative data of all patients who underwent a liver resection from 2009/2012 to 2001/2015, were collected prospectively. All robotic resection patients were matched 1:1 to patients who underwent open surgery. Pre- and perioperative data, up to 30 days, were analyzed.

Results: Sixteen robotic and open hepatic resections were identified. Fewer complication events and shorter lengths of stay (LOS, 7.9 versus 11 days, P = 0.0603) were observed for robotic resections. Length of stay in the intermediate care unit (IMC) was shorter after the robotic procedure (10 h vs 16.6 h, P = 0.0699). Operating room (OR) time was significantly longer in the robotic resection cohort (352.8 vs 239.6 min, P = 0.0215). All tumor margins were negative.

Conclusions: This preliminary comparison demonstrates the general feasibility of minor robotic liver resection in selected cases.
