METHOD FOR PREDICTING GASTRODUODENAL ULCER HEMORRHAGE RELAPSE RISK

摘要

FIELD: medicine.;SUBSTANCE: method involves measuring physical characteristics of gastroduodenal mucous membrane. Arithmetic mean of microcirculation index is calculated twice every time during 3 min. One value is calculated from mucous membrane surface on ulcer defect boundary M₁ and the other one 3-4 cm far from the boundary M₂. Hemorrhage risk coefficient K_hr is calculated as M₁/M₂. The value being greater than 0.8, low ulcer hemorrhage relapse risk level is predicted. K_hr value being from 0.5 to 0.8, moderate risk level is predicted. The value being less than 0.5, high an ulcer hemorrhage relapse risk level is predicted.;EFFECT: high accuracy of prognosis.
