[Duodeno-gastric reflux and its consequences after resection of stomach by Billroth II and Roux methods].

The severity of the duodenogastral reflux (DGR) and its deteriorative effect on the mucous membrane of gastric stump with the help of dynamic scintigraphy of the liver, fibrogastroscopy, morphological and morphometrical methods in patients, who underwent stomach resection by Billroth-2 and Roux methods, were studied. It was established, that after resection of the stomach by Billroth-2, extensive DGR appeared, vachiny 14.8%. At the same time extensive inflammatory, atrophyc and methaplastic changes are developed in the mucous membrane of the gastric stump disregeneration and prolipherative processes were progressing. The optimal gastroenteroanastomosis, preventing reflux of duodenal contents into gastric stump lumen and development of its extensive morphological changes, is considered to be Roux type anastomosis with distal (efferent) loop 40 cm of length (DGR made up 0.9%).
