side-to-end coloanal anastomosis  listen  (... KOH-loh-AY-nul uh-NAS-toh-MOH-sis)

  A surgical procedure in which the side of the colon is attached to the anus after the rectum has been removed. A section of the colon about 2 inches long is formed into a mini-pouch in order to replace the function of the rectum and store stool until it can be eliminated. This procedure is similar to the J-pouch coloanal anastomosis but a much smaller pouch is formed.
