Abstract

Purpose

Transanal surgery remains both an innovative approach to rectal pathology and a demonstrated technical challenge. Improved technology using a single-port system robotic platform (SPS) offers a promising option for this surgery.

Methods

SPS robotic system was utilized to perform submucosal, full-thickness and cylindrical excision on four cadavers. Operative performance and surgeon fatigue were measured.

Results

On all types of resections, the SPS system performed well. There were no piecemeal or fragmented resections. Closure was judged to be good to excellent in all cases. Surgeon assessment of setup and performance of the SPS was excellent in all cases.

Conclusions

SPS robotic transanal surgery represents an exciting new option for transanal surgery.
