Topicality.Adhesive intestinal obstruction is a common disease in abdominal surgery with a significant increase from year to year. During the last 20 years, the frequency of cases of adhesive intestinal obstruction (SCN) has increased by 2 times and has no tendency to decrease. In the UK, small bowel obstruction was an indication for 51% of all emergency laparotomies. Scott et al. reported seven emergency surgeries, accounting for 80% of all hospital admissions, morbidity, mortality, and health care costs in relation to general surgery in the United States. These seven operations included partial colectomy, small bowel resection, cholecystectomy, peptic ulcer surgery, adgeolysis, appendectomy, and laparotomy. Adhesive intestinal obstruction of the small intestine was the most frequent diagnosis in the behavior of four out of seven surgical interventions (partial colectomy, resection of the small intestine, adgeolysis and laparotomy). Postoperative adhesive processes are the main cause of small intestine obstruction, accounting for 60% of cases. Among all cases of intestinal obstruction, acute small intestine is 64.3–80%, while having a severe course and a worse prognosis. This causes a high mortality rate in this pathology. It ranges from 5.1% to 8.4%, occupying a leading place among all urgent diseases.

The purpose of the studywas to evaluate various modern methods of diagnosing adhesive intestinal obstruction.

Material and methods.In this study, the method of classical analysis of domestic and foreign literature was applied, based on current data on the diagnosis of adhesive intestinal obstruction.

Results.Historically, there has been a certain algorithm for examining patients arriving with suspected adhesive intestinal obstruction, which includes: complaints, anamnesis of the disease and life, objective status, as well as additional diagnostic methods. Patients with OCD usually present a wide range of complaints, such as nausea, vomiting and periodic abdominal pain. Nausea and vomiting follow the appearance of pain and are an early sign of proximal adhesive OCN. However, clinical symptoms are only partially able to diagnose adhesive intestinal obstruction. Laboratory data are of little significance in the diagnosis of intestinal obstruction, but they help to determine the presence and severity of metabolic disorders, homeostasis disorders, as well as to indicate possible starngulation. For the diagnosis of OCN, OBP survey radiography is routinely used. Computed tomography (CT) has a higher sensitivity and specificity compared to abdominal X-ray examination and is recommended by the Bologna Guidelines. Ultrasound examination (ultrasound) is increasingly used in the diagnosis of OCD. Ultrasound is a relatively simple inexpensive non-invasive imaging method that is devoid of radiation exposure, but depends on the operator's experience. To minimize the effects of ionizing radiation in children and pregnant women, magnetic resonance imaging is an effective alternative to computed tomography for intestinal obstruction.

Conclusion.The problem of adhesive intestinal obstruction remains highly relevant, given the prevalence of the disease and high mortality rates. Currently, new promising methods for diagnosing this disease, including biomarkers and high-tech methods for visualizing the pathological process, such as computed tomography and magnetic resonance imaging, are acquiring high importance. At the same time, one should not forget about the routine research methods – X-ray of the abdominal cavity and classical methods of examining the patient – collecting complaints, anamnesis and determining the objective status.
