The Subject

Intestinal obstruction is one of the chapters of modern surgery, where not all questions have yet been clarified and developed, which can be seen at least from the fact that this topic is the subject of discussion at the congresses and does not leave the pages of the surgical press. One thing is certain that the therapy of acute obstruction is exclusively surgical.

Effects of muscular activity on local blood flow have been delineated in other muscular organs but are part of a complex relationship in the small intestine. Some of our inability to provide a clear picture of the circulatory events surrounding intestinal motility relates to the variety of imprecise techniques that have been used to explore the relationship. Distension of the gut impedes blood flow through the intestinal wall, especially in the mucosa. Stimulation of motility evokes more variable responses in the intestinal circulation, including increases in blood flow; however, the circulatory response reflects mostly the nature of the intervention used to activate motility. Many motor stimuli in the gut have intrinsic vasoactive properties. Spontaneous motor events seem to have only small effects on total blood flow to the small intestine. Reduction in blood flow to the gut evokes initial increases in motility followed by inhibition of motor activity. Products of metabolism in the intestine influence both motor and vascular reactivity. More sensitive methods need to be developed to separate the types of intestinal motor activity, to localize mechanical events in specific sites in the wall of the gut, to better record electrical correlates of motility, and to measure local tissue blood flow. These technical developments will permit delineation of the linkage between motor and vascular events and should identify the regulatory factors.

Summary. Disruption of the motor-evacuation function of the digestive canal is an integral cause of the adverse course of acute obstruction of the small intestine and as a consequence of high lethality in this pathology. Purpose of the study. To study the motor activity of the gastrointestinal tract in patients with acute obstruction of the small intestine and its effect on the course of the disease in the postoperative period to create effective, sound methods of treatment of these patients. Materials and methods. Complexly after surgery, 221 patients with acute obstruction of the small intestine were examined. Used clinical and instrumental methods for the study of motor-evacuation function of the gastrointestinal tract (electrogastrography, electroenterography, phonoenterography), determined the degree of intoxication syndrome (leukocyte index of intoxication, molecules of medium mass), nonspecific resistance to organism operating-anesthetic index on ASA scale. Results and its discussion. Functional state of the patient with acute obstruction of the small intestine, its comorbidity affects the degree of operativeanesthesiological risk and the state of the motor-evacuation function of the digestive canal. It was found that inhibition of the motor function of the digestive tract in the first three days after surgery led to an increase in the level of intoxication, requiring its mandatory correction. Conclusions. A promising direction in the treatment of patients with acute obstruction of the small intestine is to develop measures that contribute to the preservation, protection and restoration of motility of the digestive tract at all stages of treatment.
