Objective The most recent guidelines for colposcopy practice in the United States, the 2017 Colposcopy Standards Consensus Guidelines, did not include recommendations for endocervical curettage (ECC). This document provides updated guidelines for use of ECC among patients referred for colposcopy. Methods Consensus guidelines for the use of ECC were developed in 2012. To update these guidelines in concordance with the 2017 Colposcopy Standards process, an expert workgroup was convened in 2021. Literature had been previously reviewed through 2011, before the 2012 guideline. Literature from the years 2012–2021 and data from the NCI Biopsy study were reviewed, focusing on the additional yield of ECC. Results Endocervical curettage is recommended for patients with high-grade cytology, human papillomavirus 16/18 infection, positive results on dual staining for p16/Ki67, for those previously treated for known or suspected cervical precancer or considering observation of cervical intraepithelial neoplasia grade 2, and when the squamocolumnar junction is not fully visualized at colposcopy. Endocervical curettage is preferred for all patients aged older than 40 years. Endocervical curettage is acceptable for all nonpregnant patients undergoing colposcopy but may be omitted when a subsequent excisional procedure is planned, the endocervical canal does not admit a sampling device, or in nulliparous patients aged younger than 30 years, with cytology reported as atypical squamous cells of undetermined significance or low-grade squamous intraepithelial lesion regardless of whether the squamocolumnar junction is fully visualized. Endocervical curettage is unacceptable in pregnancy. Conclusions These guidelines for ECC add to the 2017 consensus recommendations for colposcopy practice in the United States.
