Journal Article
Gordon, G. S., Warburton, S., Parkes, S., Kerridge, A., Parra-Blanco, A., Ortiz-Fernandez-Sordo, J., & Fitzgerald, R. C. (2024). Cytosponge procedures produce fewer respiratory aerosols and droplets than oesophagogastroduodenoscopies. Diseases of the Esophagus, 37(3), Article doad061. https://doi.org/10.1093/dote/doad061

Esophagogastroduodenoscopies (EGD) are aerosol-generating procedures that may spread respiratory pathogens. We aim to investigate the production of airborne aerosols and droplets during Cytosponge procedures, which are being evaluated in large-scale...

The low five year-survival rates for gastrointestinal cancers evidences a strong clinical need to improve their early detection. Current imaging methods for early detection are expensive and rely on white light imaging which lacks sufficient contrast...

Modified bronchoscopy masks mitigate aerosols during gastroscopies (2022)
Working Paper
Phillips, F., Crowley, J., Warburton, S., Gordon, G. S., & Parra-Blanco, A. Modified bronchoscopy masks mitigate aerosols during gastroscopies

Digestive endoscopy has been proven to produce aerosols (1–3). This represents a risk of infection by COVID-19 and other airborne viruses. A number of protective barriers have been proposed to minimise that risk. Continuous suction of the oral cavity... Read More about Modified bronchoscopy masks mitigate aerosols during gastroscopies.
