Comparison of the Consistency and Application Value of Transabdominal Intestinal Ultrasound and Computed Tomography Enterography in the Diagnosis of Inflammatory Bowel Disease Complicated With Intestinal Stenosis.

Objective To explore the consistency and clinical application value of transabdominal intestinal ultrasound (IUS) and computed tomography enterography (CTE) in the diagnosis of inflammatory bowel disease (IBD) complicated with intestinal stenosis. Methods A retrospective study was conducted on 115 patients diagnosed with IBD in Beijing Friendship Hospital,Capital Medical University from 2015 to 2024 and who underwent both IUS and CTE examinations during the same period.Clinical and imaging data were collected.Endoscopy was used as the gold standard to compare the detection,localization,and diagnostic efficacy of the two methods for intestinal stenosis and evaluate their consistency. Results A total of 115 patients (70 with Crohn's disease,22 with ulcerative colitis,and 23 with unclassified IBD) were included.In the diagnosis of stenosis among all the IBD patients,the sensitivity of IUS (86.2%) was higher than that of CTE (66.7%),while the specificity of CTE (57.1%) was better than that of IUS (35.7%).The two methods exhibited poor consistency in diagnosing intestinal stenosis (κ=0.056),while they were consistent in identifying pre-stenotic dilation (κ=0.614) and localizing the affected intestinal segments (κ=0.691).The intestinal wall thickness values measured by CTE were systematically higher than those by IUS. Conclusions IUS and CTE have complementary values in the diagnosis of IBD complicated with intestinal stenosis.IUS with higher sensitivity is suitable for screening and long-term follow-up,and CTE with better specificity is suitable for comprehensive anatomical assessment.Clinically,the appropriate choice and application should be made based on specific scenarios and IBD subtypes.
