Objetivos: el objetivo de este estudio fue evaluar la utilidad del cepillado y legrado endocervical durante la evaluacion colposcopica en pacientes con citologia anormal y colposcopia satisfactoria negativa. Materiales y metodos: se incluyeron 43 mujeres con citologia anormal y colposcopia satisfactoria negativa. Se realizo legrado y cepillado endocervical y compararon los resultados. Resultados: el legrado endocervical fue util en detectar neoplasia intraepitelial cervical no observada durante la evaluacion colposcopica satisfactoria. El cepillado endocervical tambien fue util, pero el legrado fue mejor. Conclusion: este estudio sugiere que el legrado endocervical puede ser de utilidad durante la evaluacion colposcopica satisfactoria negativa de pacientes con una citologia anormal .

SUMMARY Objective: the aim of this study was to evaluate the utility of endocervical curettage and brushing during colposcopic evaluation in patients having suspected changes in Pap smear and negative colposcopy. Methodology: results from 43 women having abnormal Pap smear and negative satisfactory colposcopy; endocervical curettage during colposcopic evaluation were thus compared to endocervical brushing during colposcopic evaluation. Results: the endocervical curettage was useful to detect cervical intraepithelial neoplasia no suspected during satisfactory colposcopic evaluation. The endocervical brushings was useful too, but the endocervical curettage was better. Conclusion: this study suggests that endocervical curettage can be useful during negative satisfactory colposcopic evaluation of a patient with an abnormal Papnicolaou smear. KEY WORDS Cervical intraepithelial neoplasia. Endocervical curettage. Endocervical brushing. Colposcopy.
