Motor function of the intestine in irritable bowel syndrome with constipation

Abstract

Irritable Bowel Syndrome (IBS) is a functional bowel disease in which relapsing abdominal pain is associated with bowel movements or bowel movements. Despite the numerous works devoted to the investigation of the mechanisms of IBS development, the intestinal motility in this disease has not been studied enough. The aim is to reveal the features of the motor function of the large and small intestine in irritable bowel syndrome with constipation (IBS-C) and in the case of dolichosigma. Material and methods. 84 patients with IBS-C by electromyography in comparison with a group of 25 patients with dolichosigma and a group of 35 patients with functional constipation were examined. The frequency of slow waves of the small and large intestine (patients with functional constipation) and the left parts of the colon (patients with IBS-3 and dolichosigma) by the Conan-M hardware and software complex were measured Results and discussion. IBS-C is characterized by hypomotor dyskinesia of the left divisions with pronounced spastic contractions of the smooth muscles of the circulatory layer of the gut, possibly due to the activity of stimulating serotonergic effects on the spastic activity of the circular muscle layer or inhibitory adrenergic neurons of the intermuscular (Auerbach) nerve plexus. With dolichosigma, hypomotor dyskinesia of the left parts of the colon was revealed due to stretching of the mechanoreceptors of the afferent neurons of the intramural reflex arcs.
