title: Use of the Cytobrush for cervical sampling after cryotherapy.
abstract: The presence of endocervical cells in routine gynecologic smears (prepared from spatula and cotton swab samples) and Cytobrush smears was analyzed in 52 patients with a history of prior cryotherapy. These cases represented 11% of the 491 women evaluated using both techniques between August 1, 1987, and January 31, 1990. The routine smear contained endocervical cells in 25 (48%) of the 52 cases while the Cytobrush smear contained endocervical cells in 49 (94%) of the cases. The use of the Cytobrush for cervical cytologic screening thus appears to be of value in patients with a prior history of cryotherapy, which frequently renders the transformation zone less accessible to routine sampling.
