RESUMO
A comparative analyses of a functional capacity of different variants of gastro-duodenal anastomoses has been done in 108 patients operated for gastro-duodenal ulcers. Functional similarity of the direct anastomosis and the transversal termino-lateral gastro-duodenoanastomosis (TL GDA) was identified. It makes a chance to give prefferance to the direct anastomosis, being more simple in performance. The restoration of continuity of gastro-intestinal tract by TL GDA (after the Bilroth-1 operation) should be performed in case of impossibility of creation of a direct GDA. The mentioned types of anastomoses provide a low rate postgastroresection syndrome. The function of gastro-gastric anastomosis and pyloric sphincter after pyloropreserving gastric resection should be studied profoundly and the expanding of indications for this procedure is premature. The differential approach to draining anastomosis in operation of vagotomy is advocated.
