Incremento de la detección de lesiones cervicales mediante inspección visual. Puerto Esperanza. 2008Incremento de la detección de lesiones cervicales mediante inspección visual. Puerto Esperanza. 2008Las pruebas visuales del cuello uterino mediante ácido acético al 4-5 % (IVA) y Lugol (IVSL) contribuyen a detectar lesiones. Este constituye el primer reporte de su uso en Cuba. Objetivo: demostrar el incremento de la detección de lesiones cervicales premalignas y malignas mediante el uso de pruebas visuales en la APS. Método: estudio de casos-controles en Puerto Esperanza, Viñales, 2008. Universo: Mujeres de 15-64 años con relaciones sexuales penetrantes. Muestra: Mujeres con pruebas visuales y citología alterada (n1= 18 casos) o no (n2= 178 controles). En Patología de Cuello se les practicó colposcopia y biopsia dirigida o por conización con asa diatérmica. Se calcularon frecuencias absolutas y relativas porcentuales y la probabilidad de detectar lesiones por las pruebas aisladas o en conjunto, además de las pruebas de rendimiento diagnóstico. Resultados: IVA e IVSL resultaron positivas en 92.9% y 79.6%, respectivamente. La probabilidad conjunta de tener lesiones fue 0.7395. Con citología alterada el 88.9 % tenía IVA+ y 77,9 % tuvo IVSL+. La colposcopia resultó positiva en el 70.9 % y la probabilidad de tener una lesión mediante pruebas visuales y la colposcopia fue 0.516. De las 136 mujeres biopsiadas resultaron útiles el 99.3%, de las cuales casi el 50 % tuvo lesiones premalignas/malignas. Las pruebas de rendimiento fueron superiores para la IVA y la IVSL que para la citología. No se detectó cáncer invasor, pero sí carcinomas in situ. Conclusión: las pruebas visuales aumentaron la cantidad de diagnósticos en 4 veces y debe generalizarse su uso.DeCS: ABSTRACTVisual examination of cervix using acetic acid up to 4-5% (VIA) and Lugol's solution (VILI) contribute to detect lesions. This constitutes the first report of their use in Cuba. Objective: to demonstrate the detection increase of pre-malignant and malignant cervical lesions by means of visual examination in Primary Health Care. Method: control-case studies in Puerto Esperanza, Viñales municipality in 2008. Target group: women from 15 to 64 years old who practice penetrating sexual relations. Sample: women who underwent visual examinations and altered cytology (n1= 18 cases) or not (n2= 178 controls). In Cervix Pathology Office, colposcopies either by directed biopsy or conization with diathermal ansa were practiced; calculating absolute and relative percentage frequencies and the probability to detect lesions by isolated tests or in set, together with the tests of diagnostic performance. Results: VIA and VILI were positive in 92.9% and 79.6%, respectively. The joint probability of presenting lesions was 0. 7395. Those showing altered cytology (88.9%) had positive VIA and 77, 9% positive VILI. Colposcopy resulted positive in 70.9% and the probability of having a lesion, proved by visual examination, simultaneously with colposcopy was 0.516. Biopsies performed to 136 women were useful (99.3%), out of them, almost 50% presented pre-malignant and malignant lesions. Yield tests were superior to VIA and VILI than to cytology. Non-invasive cancer was detected; however in situ carcinoma was. Conclusion: visual examination increased the number of diagnosis 4 times, thus its use must be generalized.DeCS: PRECANCEROUS CONDITIONS, CERVIX UTERI, CYTODIAGNOSIS, UTERINE CERVICAL NEOPLASMS, COLPOSCOPY.
