The reported oncological outcomes of this approach for stage I disease are excellent, with local recurrence (LR) rates of 3%, and 5-year survival as high as 93%.1 But TME is a major operation associated with some mortality and significant morbidity. More than one in three patients develop perioperative complications.2 Anastomotic leak with low rectal anastomosis occurs in approximately 10% of patients, and has been associated with poor oncological outcomes.3,4 Injuries to the hypogastric and pelvic nerves can cause genitourinary dysfunction in up to 40% of patients5; functional disturbances such as tenesmus, bowel urgency, soiling, and fecal incontinence are also common.6 To prevent the consequences of anastomotic leak, many patients are given a temporary diverting loop ileostomy, which is inconvenient and adds to the burden of morbidity.7 In addition, between 20% and 30% of all rectal cancers—and a higher proportion of patients with distal rectal cancers—require an abdominoperineal excision (APE) of the rectum with a permanent colostomy, a procedure that significantly impacts patients’ quality of life.5
