low anterior resection
total mesorectal excision


To confirm the safety and performance of the da Vinci SP Surgical System, Instruments and Accessories in a complex colorectal procedure such as low anterior resections or right colectomy.


Primary Performance:

  • The primary performance endpoint will be assessed as the ability to complete the planned da Vinci SP-assisted colorectal procedure without conversion to an alternate approach. Conversion to an alternate approach comprises conversion to open, multiport laparoscopic*, multiport robotic or hand-assisted approach requiring undocking of the da Vinci SP Surgical System in order to complete the planned procedure using the alternate approach.
  • Performing an extracorporeal anastomosis is not considered a conversion ** Use of additional assistant laparoscopic port(s) is not considered a conversion Laparoscopic or robotic with hand assistance

Primary Safety:

The primary safety endpoint will be assessed as the incidence of all intraoperative and post-operative adverse events that occur through the 42-day follow-up period
