A multi-centre observational study to assess a novel endoscopic device in imaging the upper GI tract: (The E.G. Scan study)

1st April 2012

Status: Ended

Specialism: Upper GI.

Team: Professor Krish Ragunath.

There are certain “silent” conditions like Barrett’s Oesophagus (a condition which can rarely cause cancer of the gullet)and Oesophageal Varices (swollen veins in the gullet which can sometimes cause serious bleeding) that can happen in patients who may otherwise not have any symptoms. If these are detected and treated early then patients could potentially avoid future serious complications. In order to detect these conditions, doctors have to perform tests on a large number of patients who are likely to have them, but unfortunately this cannot be done in the NHS at the moment partly because there is no agreement among specialists as to what is the best test to use.

Although a standard camera test can detect these conditions, it is not suitable to use for this purpose because it has many limitations. It is performed in the hospital usually under conscious sedation to increase comfort. Performing the test demands a lot of planning and has many cost considerations as it requires patient observation, experienced nursing staff, recovery rooms, cleaning equipment and medications.

There is a lot of research evidence that “transnasal cameras” (very thin cameras inserted through the nose) are more comfortable to patients because they do not cause gagging and retching, therefore do not require sedation. They are safer than standard cameras and are as accurate.

The purpose of this study is to compare a new camera called “The E.G. scan” to the standard camera test. We want to know whether it is as accurate and also whether it is acceptable to patients. It is much thinner than the standard camera test, therefore can be inserted through the nose with less chance of retching and gagging. It does not need sedation. The camera tube is disposable so there is no risk of cross contamination. The results of this study will help us decide whether this new camera might be the ideal test to detect patients with these two conditions and potentially benefit the wider population who could be affected.
