【摘要】：目的探讨运用PRWY阴道镜智能诊断评估技术(PRWY系统)正确识别正常阴道镜所见(NCF)和宫颈低级别鳞状上皮内病变(LSIL)的原则。方法选取2013年9月至2014年8月北京大学第一医院妇产科601例经阴道镜检查后组织病理诊断为慢性宫颈炎或LSIL的病例,描述PRWY系统的5个指标中NCF和LSIL的分布情况;利用卡方独立性检验分析5个评估指标、年龄、薄层液基细胞学(TCT)的结果与组织病理学结果有无关联;以LSIL的漏诊率在20%以内为可接受范围,结合年龄与TCT结果判别NCF和LSIL。结果根据PRWY系统,阴道镜下指标"红红黄"、"红红浅棕"、"红白浅棕"中NCF的比例为64.10%、82.98%、73.28%;"粉白黄"和"粉白浅棕"中LSIL的比例为53.64%和46.15%;"红红浅棕"、"红白浅棕"且年龄≥50岁、"红红黄"且TCT正常的患者中NCF所占的比例分别为82.98%、95.24%和87.50%,判定为NCF,其他条件下判定为LSIL。结论通过PRWY系统的5个评估指标,同时结合年龄和TCT的结果,可判别NCF和LSIL。
[Abstract]:Objective to explore the principle of correct identification of normal colposcopy (NCF) and cervical low grade squamous intraepithelial lesions (lsil) by using PRWY colposcopy intelligent diagnosis and evaluation technique (PRWY system). Methods from September 2013 to August 2014, 601 cases of gynecology and obstetrics department in the first Hospital of Peking University were selected, and the distribution of NCF and lsil in the five indexes of prwy system were described. Chi-square independence test was used to analyze five evaluation indexes, age, TCT results and histopathological results, and NCF and LSILs were judged with age and TCT results, taking the missed diagnosis rate of lsil within 20% as the acceptable range. Results according to the PRWY system, Under colposcopy, the ratio of NCF in "red yellow", "red light brown", "red white light brown" and "red white light brown" was 64.101.98 and 73.28; the proportion of lsil in "pink yellow" and "pink light brown" was 53.64% and 46.15%; "red light brown", "red and white light brown" and age 鈮，
