A Kock pouch is a continent pouch formed by the terminal ileum after colectomy. The procedure was detailed and first performed in 1969 by Dr. Nils Kock.^{[citation needed]}

Indications

Kock pouch ileostomy is indicated for patients who are unfit for ileal pouch anal anastomosis (IPAA) because the anus and anal sphincter will be removed during the operation; and patients who develop severe incontinence after IPAA.^[1]

A Kock pouch need not be created during the initial colectomy surgery.^{[citation needed]}

Details

The pouch has a volume of 500ml to 1000ml so that feces can be stored temporarily and the patient need not carry a stoma bag. This improves the patient's quality of life. A valve is constructed by intussusception of the terminal ileum,^[2] thereby containing the stored feces.^[1]
