METHOD FOR PREDICTION OF DEVELOPING AND PROGRESSING RUFLUX OESOPHAGITIS Russian patent published in 2014 - IPC A61B1/273 A61B10/00 

FIELD: medicine.

SUBSTANCE: what is involved is an endoscopic assessment of a degree of oesophageal involvement. The oesophagus is stained with 0.3% Congo red 2-3 ml through a spray catheter with maximum air insufflation. A length of the stained oesophageal segment (h) from a Z line with the stain colour changed by blue-black is measured in cm. Stain completeness coefficient K of an oesophageal circle is visually estimated as 1 for complete staining, and as 3/4, 1/2, 1/4 for partial staining. The derived data are used to calculate an area of the oesophageal involvement (S) by formula: S=27πrhK, wherein r=1 cm. If the patient shows no endoscopic signs of oesophagitis, though has pathologically acidic reflux oesophagitis with S>3.14 cm², a high risk of degree I reflux oesophagitis is predicted. The value S>9.42 cm² in the patient degree I reflux oesophagitis enables predicting a high risk of a transformation into degree II reflux oesophagitis .

EFFECT: simple and information-bearing method enables the early detection of the patients relating to a risk of developing and progressing reflux esophagitis, provided prevention of developing and progressing organic changes of the oesophagus for the timely administration of a therapy.
