Abstract
The principles of construction of a continent ileostomy by means of a reservoir as originally described by Kock are reviewed. Roentgenologic studies in 5 patients with such reservoirs are described. There may be a correlation of incontinence with peristaltic activity as well as nipple valve extrusion. The radiologic features are explained in terms of the anatomy of the reservoirs. One patient with postoperative ileitis is described. Roentgenologic studies may be of particular value to the surgeon in follow-up of these patients by demonstration of postoperative nipple valve extrusion and inflammatory changes in the pouch or remaining small intestine.
