Bowel Surgeries and Diversions

Colostomy - A portion of the large colon or rectum is removed, and the remaining colon is brought to the abdominal wall to form a stoma. It may be temporary or permanent. It requires an external pouch.

Ileostomy - The large intestine is removed and the small intestine (usually at the end of the ileum) is brought through the abdominal wall to form a stoma. It may be temporary or permanent. It requires an external pouch.

Ileoanal Reservoir (J-Pouch) - The colon and most of the rectum are surgically removed. An internal pouch is formed out of the terminal portion of the ileum that is attached to the anus, and the existing anal sphincter muscles are used for continence.  There is no stoma. In addition to the "J" pouch, there are "S" and "W" pouch geometric variants. It is also called ileoanal anastomosis, pull-thru, endorectal pullthrough, pelvic pouch and, perhaps the most impressive name, ileal pouch anal anastomosis.

Continent Ileostomy (Kock Pouch) - An internal pouch is constructed from the small intestine, with a valve, and a stoma is brought through the abdominal wall to be evacuated with a tube inserted into the pouch several times a day. This procedure has generally been replaced in popularity by the ileoanal reservoir.


When I first had my ostomy, I felt like I was one of a few. At MMOA I am one of many. The support and friendship of the group is a blessing.
