Improving detection of Barrett's Oesophagus in a simple, patient-friendly and quick way

The Cytosponge is a new medical test that aims to improve early detection and surveillance of Barrett’s Oesophagus. It is a quick, safe and accurate test that can be performed in a regular GP surgery. The test is meant for patients who have had gastroesophageal reflux disease (GORD) symptoms for several years.

The Cytosponge test in 3 steps

Step 1: Swallow the Cytosponge

You swallow a capsule attached to a thread containing the Cytosponge with some water at your GP.

Step 2: Cytosponge expansion

The capsule dissolves in your stomach and the Cytosponge expands. This takes between 5 and 7 minutes.

Step 3: Cytosponge retrieval

A nurse pulls on the string attached to the Cytosponge for retrieval. This process takes 1 to 2 seconds.
