Abstract
The argument in favor of the routine double-contrast examination of the colon is illustrated. A simple method of cleansing the bowel prior to the X-ray examination is described, using a colon actuator introduced in a special way with the patient rocking himself from side to side in the supine position. This avoids all aperients and is limited to a single washout given 1 hr. before the X-ray examination is to be undertaken. A 1-stage contrast technique is described using a rotating cradle stretcher to obtain accurate radiography and facilitate the introduction of the Ba and gas by means of a self-contained pressurized system.
