| Core Tip |
Endoscopy-related infections are underestimated due to difficulties in diagnosis, misdiagnosis, and underreporting. Bacterial contamination during colonoscopy poses a significant challenge, yet limited research has focused on bacterial aerosols, particularly those originating from the biopsy valve. This study introduces a simple yet effective approach to mitigate bacterial aerosol contamination in the endoscopy room. Our findings demonstrate that covering the biopsy valve with an enzymolysis gauze during colonoscopy significantly reduces airborne bacterial aerosols. This could improve safety for both patients and healthcare personnel. |
