The utility of endocervical curettage: does routine ECC at the time of colposcopy for low-grade cytologic abnormalities improve diagnosis of high-grade disease?

Abstract

To determine the use of endocervical curettage at the time of colposcopy for low-grade cytologic abnormalities. We conducted a retrospective chart review of women with low-grade Papanicolaou smears who had undergone satisfactory colposcopic examinations with identifiable lesions. We evaluated results during a 2-year period thereafter to determine whether endocervical curettage increased the diagnosis of high-grade dysplasia. The study group consisted of 374 patients. Of these patients, 16 had endocervical curettages suggestive of high-grade dysplasia. Of these 16 patients, 4 did not have concomitant high-grade dysplasia identified on ectocervical biopsy. Therefore, 93 to 94 endocervical curettages needed to be performed to detect 1 case of high-grade dysplasia that would not have been identified otherwise. Routine endocervical curettage at the time of satisfactory colposcopy for low-grade cytologic abnormalities with a visible lesion does not significantly improve the diagnosis of high-grade dysplasia.
