A swallowable sponge attached to a string will help detect precancerous changes in the esophagus in 10 minutes without endoscopy. It is reported on this website University of Cambridge.
Currently, precancerous changes in the esophagus and stomach are detected using endoscopy, a labor-intensive, uncomfortable and invasive process in which a long tube with a camera is inserted into the esophagus. Scientists have developed an alternative: a small capsule with a sponge on the end of a string. When swallowed, the membrane dissolves and the sponge is pulled upward by a thread, painlessly collecting the esophageal cells. This test only takes 10 minutes and can be done in your doctor’s office.
Now, in a study involving 120,000 patients diagnosed with Barrett’s esophagus, scientists plan to find out whether the new method could replace endoscopy. It is estimated that the sponge capsule can detect 10 times more cases of Barrett’s esophagus than standard endoscopy.
The number of esophageal cancer cases has increased sixfold since the 1990s. On average, only 12% of patients survive more than five years after diagnosis. However, approximately 59% of esophageal cancer cases are preventable, but this requires an effective screening method.
