The capsule dissolves in the stomach after swallowing, releasing the sponge which is then retrieved by gently pulling the string after five minutes. As the sponge is pulled out it collects the cells from the lining of the gullet.\n\nThe Cytosponge™ will be processed for evidence of residual cancer through analysis of cellular atypia and molecular biomarkers.
