The study substantiates the efficacy of the Roux reconstruction of the upper gastrointestinal tract in the surgical treatment of postresectional and postgastrectomic syndromes. Such reconstructive operations were performed in 16 patients. There were no postoperative mortality or specific complications registered. The short and long-term follow up demonstrated good compensation of the disorders, caused by the earlier radical gastric surgery. Thus, the method of the Roux reconstruction, amplified by the creation of functionally active sphincters and valves provides the satisfactory relief of the operated stomach disease.
