Comparación del cepillo endocervical y la torunda de algodón para la toma citológica cervical

Abstract

ObjectiveTo compare the quality and diagnostic yield of cervical cytologic sampling according to the Bethesda System 1988–1991 based on the use of an endocervical brush or cotton swab. Material and methodsWe performed a randomized study of 595 women distributed in two groups. Cervical sampling was performed with a cotton swab and wooden spatula in group A (305 women) and with a cervical brush and wooden spatula in group B (290 women). ResultsThere were no statistically significant differences in the clinical or demographic features of the two groups. No differences were found in the effectiveness of the two sampling methods in detecting cytological alterations or collection of endocervical cells. Satisfactory smears for interpretation were obtained using both methods. ConclusionNo change in the traditional method of cervical sampling is required. Attempts to improve the quality and false-negative rate of samples should focus on other features.
