Robotic colorectal surgery underwent twenty-one patients since it was first used in Sep 2009 at the Fujita-Health University Hospital. We have performed 4 cases of intersphincteric resection with TME by using the da Vinci S Surgical System. The short-term outcomes and the procedure for it are described. 

Patient and Methods)
Patients cT1 and pT1 were included as indication criteria.  

Operative techniques by using the da Vinci S Surgical System:   A total of 6 port sites (using four 12mm laparoscopic ports and three 8mm da Vinci ports) were placed and the position of each port is detached 10 cm each. Total mesorectal excision with high tie of the superior rectal artery or the inferior mesenteric artery were all performed with the Robotic surgery in one cart position. After the procedure, the patient cart was detached from the patient bed. The specimen was pulled out peraually and the anastomosis was performed from the anus. 

No conversion to open or laparoscopic surgery occured. The median operating time was 491 (range 426-571) minutes and the estimated blood loss was 90(range 20-70 )g respecting. Postoperatively, One patient had a pelvic abscess that could be managed with conservative therapy. The surgical margin was negative in all cases. The number of lymphnode harvested was 19 (range, 14 – 25)

Intersphincteric resection by Robotic surgery was successly accomplished. Further experience is needed to shorter the operative time.
