[Status of x-ray contrast examination of the colon]

Findings of colon contrast examinations performed during one year are examined with regard to their incidence rate, localisation, age and sex of the patients. The x-ray findings are also compared with the results of rectoscopy and coloscopy, as well as with the results of surgery. Good agreement was found between endoscopy and trochoscopy, especially in carcinoma of the colon. The value of the colon contrast method in colon diagnosis is discussed.
