Objective: To prevent the possible functional complications after gastrectomy, to improve the quality of life and the process of early rehabilitation. Material and Methods: The study included 165 patients with gastric cancer of stage III (T3N12M0), which, depending on the method of recovery divided into 2 groups: Group 1 n = 80 patients who, after an extensive gastrectomy had reservoir formed, II group n = 85 patients who had gastrectomy performed without forming a reservoir. Results: There were no incidence of reflux esophagitis and dumping syndrome observed in the main group, while in the control group, these complications were respectively 61.2% and 25.8%. Weight gain in the main group was observed in 83.7% of patients, in the control group in 4.7%. Assessment of physical activity on the Karnovsky scale in the study group was 85.0%, while 62.0% in the control group. Within 3 months, physical rehabilitation was observed in 90.0% of patients of the main group, while in the control group it was 25.7%. Threeyear survival rate in the main group was 71.4+0.4%, while in the control group, 57.2+0.3% (P> 0.05). Conclusions: Creation of a stomach replacing reservoir after gastrectomy is adequate way in ridding patients from possible complications. Method improves the quality of life, the process of early recovery and, Khudoyorov S. S., Navruzov S. N., Juraev M. D., Eshonov A. K., and Literatura
The new test approach for evaluation of thermo-visco-elastic parameters of elastomers is designed, realized and discussed herein. The main attention is devoted to a kinematically excited rubber beam specimen under transient resonant sweep excitation. Mechanical material characteristics, i.e. Young modulus and loss angle, are identified from analytical formulas of frequency function based on measured dynamic loading and response signals. Heat material constants were estimated indirectly by numerical thermo-mechanical FE model and matching numerical and experimental results. The 'sweep' regime tests serve for estimation of thermal and mechanical dependences. Long-term fatigue tests with cyclic resonant loading enable analysis of material degradation, such as hardening and permanent deformations. and Obsahuje seznam literatury
