The value of endocervical curettage at time of cervical cone biopsy

Two hundred eighty-nine patients were evaluated over a 23-month period to assess the efficacy of postcone biopsy endocervical curettage at the time of cervical conization. One hundred eleven patients were excluded because the endocervical curettage was insufficient or not performed, the final pathology on the cone biopsy and endocervical curettage revealed no dysplasia or cancerous process, or the endocervical margins were not assessed, leaving a total of 178 patients in the study population. A negative conization endocervical margin virtually assures no disease in the upper endocervical canal. The negative predictive value in this study population was 97%. We conclude that routine endocervical curettage is unnecessary for most patients and should be primarily considered for patients who are postmenopausal or for those receiving suboptimal conizations.
