[Gastrointestinal hemorrhage in cardiosurgery in patients with endothelial dysfunction].

Aim: To estimate the prognostic value of the hypoxic test, intragastric pH-metry, and endothelial dysfunction in cardiosurgical patients at risk of gastrointestinal hemorrhage.

Materials And Methods: This prospective study approved by the ethical committee was performed based at the Department of Anesthesiology and Resuscitation, Research Institute of Cardiology, Tomsk, in 2012-2013.

[Delayed results of proximal gastrectomy in patients with esophageal and gastric varices].

An original method of proximal gastrectomy was used to eliminate hemorrhage from gastric and oesophagal varicose veins in 27 patients with portal hypertension. The follow up period varied from 1 to 23 years. The risk of hemorrhage and the degree of vein dilatation were assessed by endoscopy and endoscopic ultrasonography.
