GASTROESOPHAGEAL REFLUX DISEASE IN COMBINATION WITH CONSTIPATION: FEATURES OF THE MOTOR FUNCTION OF THE STOMACH AND SIGMOID COLON

Abstract

The aim is to study the electromotor activity of the gastrointestinal tract in patients with GERD with concomitant functional constipation Material and methods. A study was made of the electromotor activity of the gastrointestinal tract in 70 patients with GERD with concomitant functional constipation and 64 patients with GERD with normal stool. Electromotor activity (EMA) was recorded with the help of skin electrodes in the area of the projection of the stomach and sigmoid colon on the anterior abdominal wall. The amplitude-frequency characteristics of slow-wave and spike activity on the electromyogram curve were measured. Results. EMA of the stomach in patients with endoscopically confirmed GERD and the presence of constipation was characterized by increased slow-wave and spike activity. Thus, the frequency of slow waves of the EMA of the stomach exceeds the norm by 78%. The amplitude of slow waves exceeds the norm by half. EMA of the sigmoid colon in patients with endoscopically confirmed GERD and the presence of constipation was characterized by a decrease in slow-wave activity: the frequency of slow waves of the sigmoid colon EMA was 70% of the norm; The amplitude of the slow wave activity is only 0.13 ± 0.06 mV. Conclusion. In patients with GERD and concomitant functional constipation, the incidence of gastroesophageal reflux is high, the gastrointestinal tract EMA was characterized by a more pronounced motor activity of the smooth muscles of the stomach and reduced motor activity of the sigmoid colon, which creates the conditions for an increase in intestinal pressure.
