Summary

This study aims to evaluate the role of bedside Intestinal Ultrasound (IUS) as a cost-effective, non-invasive, and well-tolerated procedure within the Treat-to-Target strategy for managing Inflammatory Bowel Disease (IBD). Despite its growing use, therapeutic targets for IUS-guided treatment remain inadequately defined. The study will investigate the feasibility of IUS in monitoring transmural response and remission, and its potential to predict clinical and biochemical responses at 3 months, as well as mucosal healing at 6 and 12 months. By incorporating IUS into routine clinical care, we aim to enhance disease management and optimize therapeutic outcomes for patients with ulcerative colitis and Crohn's disease.

Intestinal ultrasound

This study employs intestinal ultrasound (IUS) to assess disease activity in Inflammatory Bowel Disease (IBD) patients. Ultrasound parameters include bowel wall thickness measurement, evaluation of vascularization via color Doppler, assessment of wall stratification, and identification of mesentery features and complications (e.g., strictures, fistulas, abscesses). For ulcerative colitis, disease activity is gauged using the Milan Ultrasound Criteria (MUC), where a score \>6.3 indicates active disease based on bowel wall thickness and vascularization. In Crohn's disease, the Bowel Ultrasound Score (BUSS) and International Bowel Ultrasound Segmental Activity Score (IBUS-SAS) assess bowel wall thickness, vascularization, stratification, and inflammatory fat, with scores \>3.52 (BUSS) and \>48.7 (IBUS-SAS) indicating active disease. IUS evaluations occur at baseline, 2-6 weeks, 12 weeks, and 6-12 months to track disease progression and treatment response.
