title: [Functional state of the gastro-duodenal area in gastro-esophageal reflux disease].
abstract: The complex study of stomach and duodenal function was performed in 150 patients with GERD. It was revealed that 84,3% of patients had increased stomach acid-production. In GERD exacerbation we found the disturbance of gastric mucosa decreasing protective properties of esophageal, stomach and duodenal mucosa. The patients had increased intragastral and intraduodenal pressure leading to decreasing of closing function of pylorus. Due to dynamic gastroscintigraphy the slowing of stomach evacuation was revealed in 69,2% patients, the acceleration - in 7,7% patients. The prevalence of bradyperistalsis was found in elecrogastromyography. The role of hormones (gastrin, insulin, cortisol, thyrotrophin, thyroxin) in disorders of gastro-duodenal complex function was shown. The complex investigation of gastro-duodenal complex function opens the pathophysiologic base of GERD and these data may be used in the choice of adequate therapy.
