New technologies for single‐site robotic surgery in hepato‐biliary‐pancreatic surgery

Abstract

Laparoendoscopic single-site surgery (LESS) aims to reduce incision-related complications by using a single surgical access through which multiple instruments are inserted simultaneously. First descriptions of LESS procedures date back to the early 90 s, but the approach initially failed to gain popularity because of technical challenges that markedly impair the principles of laparoscopic ergonomics. In recent years LESS has been increasingly applied to hepatobiliary procedures including cholecystectomies and liver resections. However, the uptake of LESS in hepatobiliary is limited. The surgical robotic platform might play a fundamental role in facilitating the uptake of LESS by the surgical community since robotic science made it possible to develop adequate technology to deal with some of the LESS issues such as restoring surgical triangulation. In this paper the current state-of-the-art for robotic LESS applied to the hepatobiliary system and emerging technologies enabling safer LESS procedures have been reviewed and future perspectives commented on the light of our experience.
