The author describes a new 127-mm (1/2-inch) bore disposable plastic enema system for administration of the viscous barium used in double-contrast colon examinations. The larger internal diameter permits simple, rapid instillation and drainage of the suspension. Faster flow in and out results in less discomfort to the patient, especially the old and handicapped, and also saves time for the patient, technician, and physician.
