Some observations on the value of endocervical curettage performed as an integral part of colposcopic examination of patients with abnormal cervical cytology

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.
