METHOD FOR ESTIMATING CICATRICIAL STENOSIS DEGREE IN PYLORODUODENAL REGION

摘要

FIELD: medicine.;SUBSTANCE: method involves carrying out endoscopic examination. Endoscopic ultrasonographic zone examination is done. Pyloroduodenal canal size is measured and its circumference length (2πR) is calculated. Cicatricially transformed tissue zone length is measured and cicatricial stenosis index I is calculated from formula I=L/(2πR)*100%. The value being from 10 to 25%, forming stenosis is diagnosed. The value being from 25 to 50%, compensated stenosis is diagnosed. The value being from 50 to 75%, subcompensated stenosis is diagnosed. The value being above 75%, decompensated stenosis is diagnosed.;EFFECT: improved diagnosis accuracy.;7 dwg
