A total of 259 patients underwent endocervical curettage as an integral part of colposcopic examination of patients with abnormal cervical cytology. The transformation zone was entirely visualized in 140 patients (54.1 per cent), and, in 8.6 per cent of this group, the endocervical curettings were abnormal. On no occasion did the endocervical curettage harbor the worst lesion when compared to the histology of the ectocervical biopsy, cone biopsy, and hysterectomy specimens. In 117 patients (45.2 per cent), the transformation zone could not be visualized in its entirety, and in 57.3 per cent the endocervical curettings were abnormal. In one patient of this group invasive carcinoma was present in the endocervical curettage, and in another patient invasive carcinoma was present in both the ectocervical biopsy and the endocervical curettage. Thus, when the entire transformation zone is not visualized in its entirety or at all, endocervical curettage appears to be of value since a frank invasive carcinoma may be diagnosed and a cone biopsy avoided.
共有259例患者接受了宫颈管刮术，作为宫颈细胞学异常患者阴道镜检查的一个组成部分。140例患者（54.1%）的转化区完全可见，在该组患者中，8.6%的宫颈管刮出物异常。与宫颈外活检、锥形活检和子宫切除标本的组织学检查相比，宫颈管刮术从未发现最严重的病变。117例患者（45.2%）的转化区不能完全可见，57.3%的宫颈管刮出物异常。该组中有1例患者的宫颈管刮出物存在浸润癌，另一例患者的宫颈外活检和宫颈管刮出物均存在浸润癌。因此，当转化区不能完全或根本不可见时，宫颈管刮术似乎有价值，因为可以诊断出明显的浸润癌并避免进行锥形活检。
