The pathogenesis of gastric mucosa lesions in elderly and senile people has many factors. It’s based on contradiction between protective factors (mucus secretion, prostaglandins, bicarbonate, microcirculation, regeneration, etc.) and aggression factors (hydrochloric acid, pepsin, bile acids, pancreatic enzymes, bacteria). In addition, such important factors as neurohumoral disorders, nutrition and vascularization of the gastric mucosa have attached.
The aim of the study was to evaluate the possible relations between microcirculation and data of gastric mucosa transendoscopy thermometry in elderly and senile patients with atherosclerosis confirmed by duplex ultrasound of extracranial brachiocephalic arteries.
Materials and methods. To solve this problem, we analyzed the results of surveys of 156 elderly and senile patients. The proportion of males and females was 1:1.
All patients were performed calorific function of the stomach by thermometry during endoscopic examination, by introducing the probe through the endoscope channel tool.
We determined the tortuosity of vessels, the linear velocity of blood flow, analyzing the structure of vessel walls, the thickness of intima-media, atherosclerotic plaques presents and the degree of stenosis.
Results of the study. The transendoscopy thermometry of gastric mucosa varies from 37,24 ± 0,12°C in the pyloric part to 37,12 ± 0,04°C in gastric cardia. Controls had the proximodistal gradient. These values were significantly reduced in elderly and senile patients from 37,24 ± 0,12° C to 36,98 ± 0,09°C and 37,04 ± 0,05°C to 36,71 ± 0,09°C in the same part of the stomach (p < 0,05).
We have determined that the average values of diameter, linear flow velocity of the left and right common carotid artery, external and internal carotid artery in elderly and senile patients were significantly lower than in healthy subjects (p < 0.05). We found a strong direct correlation between the linear velocity of blood flow in extracranial brachiocephalic arteries department and temperature gastric mucosa (r = 0, 61, p < 0,05).
Conclusions. Elderly and senile people have significant decline calorific function in gastric and blood flow in the microvasculature, which leads to the manifestation of ischemia. There was found a straight strong statistically significant correlation between the temperature of the gastric mucous and the linear velocity of blood flow in elderly and senile patients with concomitant extracranial brachiocephalic arteries atherosclerosis.
