title: The value of digital rectal examination before barium enema.
abstract: The authors recommend that the radiologist perform a digital examination of the rectum before barium enema. Rectal examination may disclose unsuspected lesions, facilitate tube insertion, indicate inadequate preparation of the colon, and aid in the decision of whether a rectal balloon is to be used.
