[Anatomo-functional status of the upper segments of the gastrointestinal tract in patients with dumping syndrome after gastrectomy by the Billroth II method].

From study of the condition of the upper gastrointestinal tract in 51 patients suffering from the dumping syndrome after Hofmeister-Finsterer modification of Billroth II gastrectomy, the authors concluded that the intracavitary pressure gradient between the gastric stump and the efferent intestinal loop, as well as the diameter of the gastroenteroanastomosis, influence the dumping syndrome. A method is suggested for measuring the diameter and surface of the gastroenteroanastomosis and measuring the intracavitary pressure in the Gastric and duodenal stump and the efferent and afferent loops of the small intestine.
