RESUMEN

La electrocirugía es la generación y aplicación de la corriente eléctrica entre un electrodo activo y otro de dispersión, fue utilizada desde 1875 por Claude Paquelin, sin embargo la corriente de alta frecuencia con rango de 350 Khz a 4.0 Mhz ideal para utilizarla en tejidos vivos con el menor daño térmico (100-200 °C) se le llama radiofrecuencia, y es empleada desde 1980 para el manejo de las lesiones intraepiteliales escamosas del cérvix; pudiendo modificar sus tipos de ondas de salida para producir un corte puro, coagulación o la mezcla de ambas, requiriendo para ello electrodos de diferentes dimensiones en forma de asa, rectangulares o esféricos, la eficacia terapéutica de escisión fluctúa en 97% con 3% de complicaciones, principalmente sangrado trans y postoperatorio, con la posibilidad de contar con un espécimen para estudio histopatológico, siendo importante el seguimiento por citología, colposcopia y pruebas de tipificación viral, ya que permite incrementar la tasa de detección temprana de las recurrencias, persistencias o el cáncer invasor.
