Radiologic evaluation of the continent (Kock) ileostomy

The continent ileostomy is a solution to the persistent difficulties of leakage, odor, and skin irritation produced by the conventional permanent ileostomy in patients who have had proctocolectomy. Patients with continent ileostomy do not use ileostomy appliances, have complete fecal continence, and need empty the ileal reservoir only 2 to 4 times a day. Radiographic examination is often of great value in assessing patients with continent ileostomy. Radiographic features of the normal continent ileostomy and complications of continent ileostomy are discussed with regard to plain film and contrast examinations.
