Robotic transanal access surgery.

Transanal use of laparoscopic instrumentation has been described in several case reports as an alternative to transanal endoscopic microsurgery (TEM). Both of these techniques have significant technical limitations due to anatomical constrictions. Robotic technology with articulating instruments has been effectively used in many areas with anatomic limitations similar to the intraluminal use within the rectum. We present the technique of a full-thickness transanal resection of a rectal polyp with endorectal suturing using a robotic platform. Larger case series and trials are needed to compare outcome and cost with TEM. Alternative robotic platforms and instrumentation may be further developed for different and more advanced indications of transanal access surgery.
