| description | Introduction. The relevance of the study is caused by the difficulties in diagnosing diseases of the small bowel (SB). Due to the prevalence and widespread introduction of X-ray computed tomography (CT) into clinical practice, its capabilities in the diagnosis of small bowel diseases are of great interest and potential.
Objective. to reveal the possibilities of computed tomography using intravenous bolus contrast enhancement in identifying the symptom of wall thickening of the small bowel and its prognostic significance in various nosologies.
Methods. Analysis of the data from MSCT studies performed according to the Protocol for the study of abdominal organs using intravenous bolus contrast enhancement and oral water intake in adult patients from 18 to 87 years of age with small bowel diseases.
Results. The article shows the possibilities of multispiral computed tomography performed according to the standard Protocol in detecting thickening of the SB wall. The range of diseases was determined for which thickening of the SB wall was one of the main radiological symptoms of the lesion. The prognostic significance of this radiological symptom is presented. The features of thickening of the intestinal wall in various diseases and other distinctive features that can be used in the differential diagnosis are described.
Conclusion. Thickening of the wall is a common sign of SB damage, which is convincingly detected in CT studies with bolus contrast enhancement. In our study, the common causes of thickening of the SB wall in primary disease were: Crohn's disease (37%), lymphoma (20%) and anastomosis (13%). However, we determined thickening of the SB wall as a result of primary tumors (adenocarcinoma, sarcoma) in 7% and as a result of a secondary tumor lesion in 18.6% of cases. The considered diseases were different in the degree of thickening of the intestinal wall (from 6 to 70 mm), its spreading (focal thickening 48%; segmental 52%), number of affected areas (from 1 to 3) of their localization (proximal-middle or distal section), form of the transition area from the affected part of the intestine to the unchanged one (sharply defined or smooth), the presence or absence of symptoms of intestinal obstruction, and the features of contrast enhancement (severity and type). |
