Which stage in the IPAA process is specifically a temporary end ileostomy?

In the process of an ileal pouch-anal anastomosis (IPAA), the first stage involves the creation of a temporary end ileostomy. This initial stage is performed to allow the remaining bowel to heal and to prepare the patient for a subsequent surgical procedure. During this stage, the ileostomy diverts waste away from the rectum and into a pouch outside the body, enabling the body to recover from the initial surgery, often related to a condition such as ulcerative colitis or familial adenomatous polyposis.

Following this stage, the remaining phases of the IPAA typically involve further surgeries to create the ileal pouch and eventually connect it to the anal canal, allowing for normal bowel function in the long term. The temporary nature of the ileostomy in this first stage emphasizes its role as a transitional step in the overall IPAA process, focusing on recovery and preparation for future corrective surgeries.
