Background: The da Vinci system is a newly developed device for colorectal surgery, therefore experience of its use for rectal cancer surgery is limited and there are no reports describing the use of four robotic arms with this system. The aim of this study is to evaluate the safety and feasibility of the four-arm da Vinci system for total mesorectal excision in rectal cancer patients. Methods: Clinicopathologic data were prospectively collected on nine patients who underwent robotic total mesorectal excision using four robotic arms for the treatment of mid or low rectal cancer between November 2006 and Febuary 2007. Patient demographics, perioperative clinical outcomes, and pathology results with macroscopic grading (complete, nearly complete, incomplete) were evaluated. Results: nine patients with mid or low rectal cancer underwent robotic total mesorectal excison using four robotic arms without serious complications. The mean length of hospital stay was 7.4 ± 1.3 days (range 5.0-10.0 days) and the mean operating time was 220.8 ± 49.4 min (range 153-315 min). Macroscopic grading of the specimen was complete in eight patients and nearly complete in one patient. There were no cases of conversion. Conclusion: In the present study, we accomplished nine robot-assisted rectal resections safely and effectively.
