Title:
DIAGNOSIS ACCURACY IMPROVING COMPOSITION FOR USE IN MAGNIFICATION ENDOSCOPY OR ULTRA-HIGH MAGNIFICATION ENDOSCOPY
Document Type and Number:
WIPO Patent Application WO/2022/059728
Kind Code:
A1
Abstract:
For the diagnosis of gastric cancer by a magnification endoscopy with narrow-band imaging or an ultra-high magnification endoscopy with narrow-band imaging in each of which observation is performed with narrow-band light, a method having high diagnostic accuracy is established. It becomes possible to perform the examination without enhancing the production of a mucus by administering pronase orally prior to the endoscopy and optionally administering pronase typically under the observation with the endoscope, without the need to stain with a dye unlike the case of other organs. In the conventional endoscopic examinations, a lesion is identified and then a definitive diagnosis is performed by a pathological examination. In contrast, when the method of the present invention is employed, possibilities that high diagnosis performance might be achieved and the diagnosis with accuracy similar to that achieved in a pathological examination might be achieved with an endoscope have been suggested. The removal of a mucus with pronase is useful in a magnification endoscopy or an ultra-high magnification endoscopy.
