Summary

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.

Detailed description

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. 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.
