METHOD OF DIAGNOSTICS OF CHRONIC PANCREATITIS IN INFLAMMATORY BOWEL DISEASES Russian patent published in 2023 - IPC A61B8/08 A61B8/12 

FIELD: medicine; ultrasound; endoscopic diagnostics.

SUBSTANCE: invention is intended for the diagnosis of chronic pancreatitis in inflammatory bowel diseases. The method includes performing endoscopic ultrasonography of the pancreas. Additionally, compression elastometry of the pancreas is performed with the calculation of the deformation coefficient. When such signs as clear contours of the gland, homogeneous parenchyma, absence of ductal abnormalities and the value of the deformation coefficient of 0.99 or less are detected, the norm is diagnosed. When clear contours of the gland, inhomogeneous structure of the parenchyma, extended lateral branches, lobular structures and values of the deformation coefficient from 1.00 to 2.99 are detected, mild chronic pancreatitis is diagnosed. If fuzzy contours of the gland, inhomogeneous structure of the parenchyma, multiple hyperechoic inclusions in the dilated lateral branches, uneven hyperechoic contour of the main pancreatic duct and values of the deformation coefficient from 3.00 to 4.99 are detected, a moderately severe degree of chronic pancreatitis is diagnosed. If fuzzy contours of the gland, an inhomogeneous structure of the parenchyma above average echogenicity, multiple cystic cavities, multiple hyperechoic inclusions with an acoustic shadow in the expanded lateral branches, an uneven hyperechoic contour of the main pancreatic duct and a strain coefficient value of more than 5.00 are detected, severe chronic pancreatitis is diagnosed.

EFFECT: method is simple, non-invasive, improves the accuracy and objectivity of the diagnosis of chronic pancreatitis in patients with inflammatory bowel diseases.
