[Study of "contrast labels"--a solution of the problems of early diagnosis of ileus caused by adhesions?].

The expediency of using a new radiocontrast "contrast label" method of examination was studied in 82 patients with suspected ileus caused by adhesions. The method is based on ascertaining the joining of the contrast labels at the site of the obstruction after their oral administration at an interval of one hour. The method is substantiated and described, and the indications are clearly formulated, the main one is suspected ileus. It is shown that the "contrast label" method is simple in techniques, informative, and has some advantages over X-ray examination with the prescription of a barium meal.

[X-ray contrast examination in surgery of adhesive intestinal obstruction].

The nature, frequency, and informative value of contrast X-ray examination of the gastrointestinal tract after oral administration of liquid barium in the adhesive disease and adhesive ileus were studied in two groups of patients (123 and 162 persons). Signs such as prolonged retention of the contrast medium in the small intestine and "sagging" of the intestine with the appearance of an X-ray contrast level in the absence of gases above it are of most diagnostic significance. Goal-oriented X-ray contrast examination made it possible to reduce the time needed for preoperative diagnosis, reduce the number of operative interventions in which the intestinal lumen is opened, and improve the immediate outcomes of treatment; mortality reduced from 19.8% to 10.5%.

[Disorder of regional mesenteric circulation as a cause of functional intestinal obstruction].

It is shown experimentally that an impaired mesenterial blood circulation is of primary importance for development of dynamic intestinal obstruction, that is in contrast with the existing opinion on the primary importance of disorders in the bowel motility. The data obtained were utilized to explain the mechanisms of a stimulating effect of different procedures in combating against dynamic intestinal obstruction, namely an elimination of the suppressive sympathetic effect on abdominal vessels and an increase of the volume blood flow.

[Experimental study of selective mesentericography in acute intestinal obstruction].

Experimentally on 76 animals (dogs) the authors have studied some diagnostic opportunities of angiography in various forms of acute intestinal obstruction: strangulation, obturation and paralytic (in peritonitis) types. Angiographic symptoms of an organic origin proved to be mainly typical for strangulation obstruction. Symptoms of a functional character reflecting disorders in mesenteric hemocirculation were found to be equally pronounced in all kinds of intestinal obstruction, these consisted in a retarded linear rate of arterial and venous blood flow, in particular.
