[Venous system of the abdomen in various diseases of the digestive tract]

On the basis of pathoanatomical (79), experimental (10) and clinical (52) investigations, it was established that in ulcer disease, gastroduodenitis, enterocolitis, the adhesions-constrictions occurred along the course of the superior and inferior mesenteric veins, which subsequently caused inflammation in the lymphatic vessels. The adhesions-constrictions compress the mesenteric veins with the resulting increase in their pressure. The suggested preparation-mobilization of the inferior mesenteric vein contributes to reduction of venous pressure in the abdominal cavity, leading to improvement in the results of surgical treatment of the ulcer disease.
