title: [Simultaneous double contrast in the diagnosis of cancer of the colon].
abstract: Usefulness of double contrast examination in diagnosis of colonic cancer is discussed. As a result of application of the procedure, tumors were detected in 74 patients, including 15 asymptomatic patients at high risk who underwent irrigoscopy in the course of a medical check-up. Examination in a double contrast was found to be of diagnostic value in the identification of tumors of all macroscopic patterns and sites. A reverse correlation between tumor size and procedure efficacy was established. A detailed description of X-ray patterns of lesions is given.
