(J-Pouch) This is now the most common alternative to the conventional ileostomy. Technically, it is not an ostomy since there is no stoma. In this procedure, the colon and most of the rectum are surgically removed and an internal pouch is formed out of the terminal portion of the ileum. An opening at the bottom of this pouch is attached to the anus such that the existing anal sphincter muscles can be used for continence. This procedure should only be performed on patients with ulcerative colitis or familial polyposis who have not previously lost their anal sphincters. In addition to the "J" pouch, there are "S" and "W" pouch geometric variants. It is also called ileoanal anastomosis, pull-thru, endorectal pullthrough, and pelvic pouch and, perhaps the most impressive name, ileal pouch anal anastomosis (IPAA).

Continent Ileostomy (Kock Pouch) In this surgical variation of the ileostomy, a reservoir pouch is created inside the abdomen with a portion of the terminal ileum. A valve is constructed in the pouch and a stoma is brought through the abdominal wall. A catheter or tube is inserted into the pouch several times a day to drain feces from the reservoir. This procedure has generally been replaced in popularity by the ileoanal reservoir (above). A modified version of this procedure called the Barnett Continent Intestinal Reservoir (BCIR) is performed at a limited number of facilities.
