POSSIBILITIES OF IMAGING RESEARCH METHODS IN INTEGRATED DIAGNOSIS OF CROHN’S DISEASE AND ULCERATIVE COLITIS

Abstract

The study aims to analyze the possibilities of various imaging research methods in early diagnosis,
staging and detection of complications in Crohn’s disease and ulcerative colitis. Materials and methods.
The complex examination was carried out in 180 patients with Crohn’s disease and ulcerative colitis who underwent
treatment in the 3rd type multi-field hospital in 2010–2020. The examination included radio-opaque methods, such
as irrigoscopy (100 % of cases), small bowel series (28 %), ultrasound examination (69 %), multispiral computed
tomography (57 %). Results. It was found that the multispiral computed tomography is the most informative
method for imaging diagnosis and staging of Crohn’s disease and ulcerative colitis (sensitivity in Crohn’s disease –
80–85 %, in ulcerative colitis – 94.1 %; specificity in Crohn’s disease – 85–87 %, in ulcerative colitis – 80 %).
The ultrasound examination was of the highest information value in detecting large fluid accumulations in abdominal
cavity (sensitivity – 75 %, specificity – 67 %). The radiographic examination proved to be the most informative
in detecting intraperitoneal free gas and signs of intestinal obstruction (sensitivity – 77 %, specificity – 69 %).
