ROUTINE LATERAL VIEW OF THE BARIUM-FILLED RECTUM: IS IT WORTHWHILE?

Abstract
1. In 2,500 consecutive barium enema examinations, only one lesion was found in the lateral view which could not be seen on at least one of the other projections. 2. In no instance was a lesion found in the rectosigmoid by barium enema examination which had been overlooked on endoscopic examination. 3. The measurement of the presacral space, even if over 2 cm., should not by itself be considered as indicative of pathology in the distal bowel or retroperitoneal space. In 71 of our 75 examinations with a measurement over 2 cm., no pathology could be found in the rectum or distal sigmoid colon.
