Abstract:
Objective:To explore the value of multiparametric ultrasonography，including grayscale ultrasound（US），color Doppler flow imaging（CDFI），and real-time shear wave elastography（SWE）in diagnosing mucosal healing（MH）in pediatric patients with Crohn's disease.Methods:This prospective study consecutively enrolled pediatric CD patients who underwent endoscopic examinations at Hunan Children's Hospital from January 2024 to August 2024. Based on the Simplified Endoscopic Score for Crohn's Disease（SES-CD），all intestinal segments were divided into two groups：the MH group and the non-mucosal healing（NMH）group. Differences in bowel wall thickness（BWT），bowel wall stratification，color Doppler grading，SWE values，and increased thickness of mesenteric fat were compared between the two groups. ROC curves were plotted to evaluate the diagnostic performance of each ultrasound parameter. Multivariate Logistic regression analysis was used to identify independent predictors of MH，and a regression model was developed based on these factors.Results:A total of 234 intestinal segments from 60 pediatric CD patients were included in the analysis，divided into the MH group（101 segments）and the NMH group（133 segments）.There were significant differences between the MH and NMH groups in terms of BWT，bowel wall stratification，color Doppler grading，SWE values，and increased thickness of mesenteric fat（all P<0.05）. The multivariate Logistic regression analysis identified BWT，color Doppler grading，and SWE values as independent predictors associated with MH（all P<0.05）.The area under the ROC curve was 0.906（95% CI = 0.867 - 0.945， P＜0.05），with a sensitivity of 0.865 and specificity of 0.851. Conclusions:Multiparametric ultrasonography can effectively assess MH in pediatric CD patients，providing critical information for accurate clinical evaluation of disease status and treatment outcomes.
