Prospective Evaluation of the Carbon Footprint and Clinical Utility of IBUS Compared to Colonoscopy and Enterography in UC and CD

Prospective Evaluation of the Carbon Footprint and Clinical Utility of Intestinal Bowel Ultrasound Compared to Colonoscopy and Enterography in Ulcerative Colitis and Crohn's Disease

Healthcare contributes approximately 4.4% of global GHG emissions, with diagnostic imaging and endoscopic services being substantial contributors. Colonoscopy and cross-sectional imaging modalities, though indispensable, are associated with high carbon emissions due to electricity use, waste, sterilisation, and transportation. IBUS, a non-invasive, real-time diagnostic modality, is increasingly validated for disease activity assessment in both UC and CD.

Colonoscopy and cross-sectional imaging modalities, though indispensable, are associated with high carbon emissions due to electricity use, waste, sterilisation, and transportation. IBUS, a non-invasive, real-time diagnostic modality, is increasingly validated for disease activity assessment in both UC and CD. Its low energy footprint and portability make it a potential frontline tool for sustainable IBD follow-up. This study aims to quantify and compare the environmental impact and diagnostic value of IBUS versus conventional imaging strategies in real-world clinical care.

All consecutive patients undergoing endoscopy procedures with consent for procedures, during the study period will be included
