Robotic abdominoperineal resection

In comparison to laparoscopic, robotic surgery for rectal cancer has not been studied as extensively, though multiple small studies have shown safety and feasibility. Robotic surgery addresses laparoscopic limitations by providing high-resolution magnified 3-dimensional imaging, articulating instruments that mimic the movement of a hand with 7 degrees of motion, superior ergonomics, and the ability to retract and control the camera without an assistant. Some robotic studies have shown lower rates of conversion, issues with sexual function, and positive circumferential resection margins. This article reviews the technical aspects of robotic abdominal perineal resection.
