This study is being conducted to evaluate the incidence and type of surgical complications occurring in patients who have a defunctioning stoma after LARfor rectal cancer. The data from this retrospective study will be analyzed by the study Sponsor to aid in designing a prospective clinical trial for a new technology that offers a treatment alternative to standard of care defunctioning stoma in patients undergoing LAR for rectal cancer.

2. Having an open or minimally invasive colorectal resection with diverting loop ileostomy surgical procedure performed between January 15, 2015 and January 15, 2019 for treatment of a known or suspected malignant condition.
3. Availability of medical records for a postoperative visit occurring 12 months (± 3 months) after the LAR surgery.

Exclusion Criteria:

1. Planned surgical procedure is a Hartmann's procedure (surgical resection of the rectosigmoid colon with closure of the anorectal stump and formation of an end colostomy).
2. Having a documented medical history of inflammatory bowel disease prior to the LAR surgery.
3. Having a concomitant major surgical procedure performed in combination with the LAR surgery (e.g., colorectal resection with hepatectomy).

Patients who underwent LAR for rectal cancer and are 12 months or longer postoperative from the LAR surgery will be reviewed for eligibility.
