Сhronic gastritis: impaired motor-evacuation function of the stomach

The effect of morphological changes in the gastric mucosa on the motor-evacuation function of the stomach was evaluated in 90 patients with chronic atrophic gastritis and 93 patients with chronic non-atrophic gastritis aged 18 to 82 years. Motor function disturbances were discovered of 90% of patients with chronic atrophic gastritis and 80,6% – with chronic non-atrophic gastritis. It was established that the pyloric insufficiency compared with its spasm was significantly more (p<0,01) often in chronic atrophic gastritis. Insufficiency of the lower esophageal sphincter in patients with atrophic gastritis was significantly (p<0,01). Insufficiency of the lower esophageal sphincter in combination with duodenogastric reflux in patients with chronic atrophic gastritis was significantly more (p<0,01) often observed during diffuse atrophy, i. e. when mucous membrane of stomach corpus and antrum is involved in the process. With the localization of atrophy in the antrum alone, pyloric insufficiency was observed significantly more (p <0,01) often than spasm. Thus, an interrelation between the insufficiency of the lower esophageal and pyloric sphincters with the diffuse atrophic process has been established. There are no significant differences of disorders of gastric motor function in patients with different types of chronic gastritis. Accelerated evacuation from the stomach with localization of atrophy in the mucous membrane of the stomach corpus is more (p <0,01) often observed in patients with chronic atrophic gastritis.
