本文对171例产前用过DES(diethylstilbestrol),阴道镜表现为镶嵌或基底者,进行研究。并将此两种病变分为Ⅰ-Ⅲ级。分级标准依上皮白色程度,表面轮廓,异常区边界的明显性,表面血管排列和弯曲度,及血管间距离。Ⅰ级改变程度轻,Ⅱ级呈中等度异常包括边界较锐利,表面轮廓较不规则及白色上皮较厚,Ⅲ级乃严重异常呈明显血管间距离变异,边界锐利及明显表面轮廓不规则。从镶嵌或基底区域共采取215个活检。每个活检都取自阴道镜最异常的区域。107个标本取自阴道和108个取自宫颈。2/3的活检取自阴道镜Ⅰ级和1/3Ⅱ级;无Ⅲ级或正常。
In this paper, 171 cases of premedication DES (diethylstilbestrol), colposcopy showed inlaid or substrate were studied. And these two kinds of lesions are divided into Ⅰ-Ⅲ grade. Grading standards according to the degree of white epithelium, surface contour, the apparent boundaries of the abnormal area, the surface vascular curvature and curvature, and the distance between the vessels. Level Ⅰ change is mild, grade Ⅱ was moderately anomalous, including the border is sharper, the surface is irregular and white epithelial thicker, grade Ⅲ is severe abnormalities were significant vascular distance variability, sharp boundary and the apparent surface irregularities. A total of 215 biopsies were taken from the inlay or basal region. Each biopsy is taken from the most unusual colposcopy area. 107 specimens taken from the vagina and 108 taken from the cervix. Two-thirds of biopsies were taken from colposcopy grade I and grade I / 3; no grade III or normal.
