They discover a new minimally invasive method as an alternative to upper endoscopy

To avoid this problem, doctors at Children’s Hospital of Colorado (USA) have devised a new technique which allows important information about the inflammatory state of the upper gastrointestinal tract to be obtained with less discomfort, allowing patients to remain awake and attentive while the surgical procedure is completed.

The best? The simplicity of this new method, and in which only one capsule hooked to a thread special, something that is also minimally invasive. Pediatric gastroenterologist Glenn T. Furuta has named it IntegerTracker or ‘thread test’, a method that also results in Low cost and very accurate.

How does it work?

This test is not so recent, it is a technique that was thought decades ago to collect fluids from the upper sections of the small intestine through the stomach, so it was used mainly in pediatrics to collect trophozoites in the study of giardiasis and other parasites, as indicated in This studio.

In itself, it consists of a capsule that the patient swallows and containing a special type of thread. This capsule follows the usual path of the digestive tract, eventually reaching the small intestine. In a matter of a few minutes, healthcare personnel can gently remove the thread by pulling on one end. Subsequently, the thread is analyzed and it is identified which section of it corresponds to each segment of the digestive tract, using parameters such as pH or length measurements.

According to studies published to date, the enterotest sensitivity to detect H. pylori oscillates between 37 and 97%although it varies greatly depending on the production and processing technique, as well as the different yarn tests used.

Its usefulness is to determine in which part locate the inflammation through the analysis of different biomarkers. For example, this technique has been shown to be effective in gastrointestinal conditions such as eosinophilic inflammatory esophagitis. Likewise, sits creators believe that it may have other apps in severe gastroesophageal reflux, eosinophilic gastroenteritis, enteropathy due to food allergy or irritable bowel syndrome. Of course, this technique, although potentially useful in some circumstances, must be more extensively validated before it can be definitively recommended.
