Air contrast colon examination in patients with colostomies.

A readily feasible technique for producing an excellent air contrast examination of the colon in patients with colostomies is described. The technique employes no special equipment and is easily tolerated by patients. Indications for the examination include a symptomatic patient with a negative conventional enema or suspicious single column examination. The surprisingly high incidence of both benign and malignant coexisting colonic neoplasms is reviewed.
