METHOD FOR DETERMINING ANTIREFLUX PROPERTIES OF GASTROENTEROANASTOMOSIS IN EXPERIMENTS Russian patent published in 1995 - IPC

FIELD: veterinary medicine. SUBSTANCE: method involves carrying out manometric examination by means of double-current catheter to determine critical level of interintestinal pressure. The catheter is introduced into the jejunum lumen through duodenostoma. The catheter balloon is placed outside the gastroenteroanastomosis line. Gastroenteroanastomosis valve property disorders are determined by means of injecting colored liquid through another catheter duct into anastomosis zone to detect dye outside the anastomosis line in stomach. Endoscopic examination of the anastomosis zone is carried out under dosed pressure. EFFECT: enhanced accuracy of diagnosis. 2 cl, 2 dwg
