[Diagnosis of chronic duodenal obstruction]

The results of examination of 111 patients with chronic duodenal obstruction (CDO) were analyzed. CDO makes up 3.8% in the whole structure of the diseases of the organs of gastro-intestinal tract, and in the structure of the diseases of pancreato-duodenal area--6.1%. Mechanical form of CDO was revealed in 43.6% of patients, functional--in 51.4%; the disease in compensated stage was detected in 38.7% of patients, in subcompensated stage--in 52.3% and in decompensated stage--in 9.0%. Clinical manifestations of the disease are characterized by diversity of symptoms, which necessitates the use of the complex of instrumental examinations. For establishment of the causes of CDO, besides the routine methods USE and computed tomography were used. In simultaneous contrast of the duodenum, the aorta and superior mesenteric artery computed tomography in comparison with other methods makes it possible to make more precise diagnosis of mechanical CDO caused by arteriomesenterial compression.
