The ileoanal pouch (from latin ileum : Hüftdarm, anus : After, English pouch : bag, pouch) is a surgical procedure , a direct connection (in which with system of a reservoir anastomosis ) between the last portion of the small intestine ( ileum ) and the anus created becomes. The technique is used in colectomy , as it is performed, for example, in ulcerative colitis . The aim of creating an ileoanal pouch is to maintain continence (voluntary defecation through the natural anus).

To form a pouch, a reservoir is artificially created from loops of the small intestine, which collects the mainly liquid intestinal contents of the small intestine and delays direct emptying. There are different ways to design the pouch. The technically simplest system is the so-called J-Pouch , which is now the standard process.

Psychosocial aspect

Despite the decisive advantage of avoiding a permanent artificial outlet from the small intestine ( ileostomy ), a pouch operation is a serious procedure that has far-reaching consequences and requires special experience on the part of the surgeon in addition to careful diagnosis. Preparation includes an informational talk with the operating doctor as well as contacting patients who have already undergone such an operation. A contact option is provided by the German Crohn's Disease / Ulcerative Colitis Association - DCCV - e. V. in the respective centers. In order to be able to make a conscious decision about the operation, one must consider from the outset that the development of the pouch's final function can take twelve months.
