Age-related peculiarities of peripheral electrogastroenterography parameters.

We studied age-specific features of peripheral electrogastroenterography (PEGEG) parameters and their influence on the assessment of findings. In 28 individuals divided into "young" (mean age 21.4 ± 2.7 years) and "elderly" (63.0 ± 7.2 years) subgroups, parameters of PEGEG were analyzed by comparing the group mean values (Mann-Whitney test) and by using discriminant analysis. Discriminant analysis revealed fi ve PEGEG indicators that allow discriminating the groups of young and older people; the most significant indicators were basal electrical activity of the stomach and colon. The influence of these differences on evaluation of gastrointestinal motility was studied in 57 patients with ulcerative pyloroduodenal stenosis (mean age 50.5 ± 19.1 years) distributed into two groups depending of the disease severity. The use of "elderly" normal values instead of "mean-aged" norm (in discriminant analysis) significantly improved the accuracy of patient distribution in groups from 85.2 to 96.4%.

Showings of studying the life quality with the aid of the SF-36 questionnaire can be used for assessing long-term results of various types of surgeries at complicated duodenal ulcer. Unlike stomach resections, functional surgeries provide a higher life quality of patients. Such differences become more apparent as time after the surgery passes by.
