Arms Assigned Interventions
Experimental: CAR™ 27
Any patient with a diagnosis of colorectal cancer that has been previously radiated to the pelvic area (6-8 weeks prior to surgery) and that is electively scheduled for an open or laparoscopic total mesorectal excision (TME) and low anterior resection surgery (< 10cm from the anal verge) which requires the creation of an anastomosis, will be offered participation in this study.
