Objective:
An objective assessment of robotic assistance in colorectal surgery.
Background:
There is a lack of objective evidence behind the claims of superior optics and improved ergonomics with robotics. This study introduces a novel method of assessing how robotics facilitates colorectal surgery.
Methods:
Operative videos of laparoscopic and robotic surgeries were reviewed. Two components were evaluated-scope-holder performance was assessed using a transparent overlay to partition the video image and provide lines for measurement; assistant instrument performance was measured using a separate matrix of movement episodes and time.
Results:
The views achieved in robotic surgery were superior and less dependent on the assistant. The degree of assistance provided by the robotic system was more than that of the human assistant.
Conclusions:
The use of robotics allows a trained operator to project his skills threefold-as a scope holder, operator and assistant-providing superior visualization and dynamic assistance throughout surgery.
