An abdominoperineal resection, also known as Miles operation, is a surgical intervention that removes the distal colon, rectum and anus and creates a permanent colostomy connecting the remaining sigmoid colon to an opening on the abdomen. It treats patients with rectal cancer or anal cancer, particularly tumors in the lower third of the rectum or anal canal where the sphincter cannot be preserved. English surgeon William Ernest Miles pioneered the operation in 1907, on the theory that rectal malignancies spread both upward and downward along the bowel, and it significantly reduced cancer recurrence rates and became the standard approach for decades before later refinements, including sphincter preserving anterior resection techniques introduced by Henri Albert Hartmann and improved bowel continuity restoration achieved by Claude Dixon in 1948.
Facts
Origin YearWilliam Ernest Miles first performed the operation in 1907. His own paper describing the technique, cited in the same section, was published the following year, in 1908. FAQs
Why does an abdominoperineal resection require a permanent colostomy?
The anus is removed along with the rectum and sphincter muscle.
The operation removes the rectum, the anus and the tissues around it, including the sphincter muscle. The American Cancer Society explains that because the anus is removed, a permanent colostomy is needed, in which the end of the colon is connected to a hole in the skin over the abdomen so that stool can pass.
