title: [Enteral dysfunction as a factor of protein-energy insufficiency development in elderly persons following gastric surgery].
abstract: 264 patients within the age group of 61-93 were observed both by the gastroenterologist and surgeon for 3-6 years following gastroduodenal ulcer surgical treatment. 31,8% developed protein-energy insufficiency (PEI) in late terms, i.e. 3-12 months after the operation. Comparative analysis with a control group showed that PEI development in elderly patients occurs under conditions of membrane and cytosol enzyme synthesis decrease in small intestine and transport system disturbance in its mucosa in postoperative period. Risk of PEI development is especially high in elderly patients with the accompanying cardiovascular pathology resulting in membrane digestion depression and absorption inhibition. The importance of membrane small intestinal digestion disorders in elderly patients in postoperative period was suggested to play a significant role in prognosis and detection of PEI in early stages.
