[X-ray method for examination of patients with obstructive diseases of the large bowel]

The paper presents a new priority X-ray method for examining the large bowel in patients with strictures. It is based on the principle of one-stage double contrasting, that has been substantially modified and supplemented by some distinctive signs and original methodological techniques. A randomized study of 150 patients with stenotic tumors of the distal colon assessed this method in comparison to traditional irrigoscopy and classical double contrasting. The study provided strong evidence for the advantage of the proposed method over the well-known ones. In the presence of stenosis, this method makes it possible to completely examine all the portions of the large bowel in 90% of the cases, to reduce the time of examination by almost 15 minutes and a radiation load per patient by 4 m3v. When the method is applied, the informative value of X-ray characteristics of a colonic stricture maximally retains. This is of great value in examining the category of patients with obstructive diseases of the large bowel, which presents a problem in making a differential diagnosis.
