Assessment of endocervical curettage in colposcopy.

Colposcopy has become an accepted diagnostic procedure in the management of patients with abnormal cervical cytology. To assess the value of the endocervical curettage in colposcopy, a retrospective review of 125 cases who had the procedure done during the 20-month period (January 1986-August 1988) was carried out. The ECC were positive in 3 out of 57 (5.3%) patients with satisfactory examination and 24 out of 68 (35.3%) patients with unsatisfactory examination. In all 27 cases, there was insufficient tissue to make a diagnosis of invasive carcinoma. Of the 125 patients studied seventy-two (29 in the satisfactory group and 43 in the unsatisfactory group) underwent conization and/or hysterectomy. Endocervical curettage did not eliminate the need for cone biopsy in all cases of unsatisfactory colposcopy. The tissue diagnosis on ECC did not increase the diagnostic accuracy derived from the colposcopic directed biopsies in either group. There were 20 cases of invasive carcinoma (13 MIC, 7 invasive) in this study, the ECC were positive in 9. We concluded that the ECC has limited value in colposcopy.
