Résumé

Introduction: The environmental impact of endoscopy, including small-bowel capsule endoscopy (SBCE), has gained attention due to its contribution to the global carbon footprint. This study aimed to evaluate the greenhouse gas (GHG) emissions (kgCO2e) of SBCE, including devices life cycle and capsule journey. Methods: SBCE devices (3 brands) were evaluated using life cycle assessment methodology (ISO 14040), including patient travelling, bowel preparation, capsule examination and video recording. A survey was conducted on 120 patients undergoing a SBCE to gather data on their transportation, activities during the procedure, and awareness of pollution generated and on 87 physicians reading capsules. Results: For the 3 different capsules, the weight was 4 g (3.9-5.2% of total), while 43 to 119 g were attributed for packaging (9-97%) including 5 g of deactivation magnets (4-6%) and 11 to 50 g for instruction forms (40%). A full SBCE generated between 19 and 20 kgCO2e, including 0.04 kgCO2e (0.2%) for the capsule itself and 18 kgCO2e related to patient travelling (94.7%). Capsule retrieval would add 0.98 kgCO2e using dedicated devices. Capsule deconstruction revealed components (e.g. Neodymium) that are prohibited from environmental disposal. 76% of patients were not aware of the illegal nature of flushing capsules, and 63% would be willing to retrieve it. Data storage and physician impact were negligible. Conclusion: The GHG emission of SBCE is mainly determined by patient travelling. The capsule device itself has a comparably low carbon footprint. Considering capsule components disposal is illegal, retrieval of the capsule seems crucial but increasing device-related emissions.
