Los autores realizaron un estudio para comparar la eficacia de Oxiplex y Gore-tex en la prevención de fibrosis peridural tras laminectomías en ratas. La fibrosis peridural es una causa común de dolor en pacientes sometidos a cirugía de la columna vertebral. Para evitar la formación de cicatriz, se han empleado numerosos materiales y métodos como los antiinflamatorios no esteroideos (AINE), Gelfoam, Oxiplex, Gore-tex, carboxymethil celulosa, Adcon-L, injertos de grasa antóloga, mitomicina o la radioterapia, pero sólo se ha obtenido resultados exitosos en pocas ocasiones. Métodos. Se realizaron laminectomías en la cuarta vértebra lumbar (L-4) en 30 ratas. Se aplicaron Oxiplex o Gore-Tex sobre la duramadre con el objetivo de realizar una evaluación ciega de sus efectos. En el grupo control, sólo se realizó la laminectomía L4. Los animales fueron sacrificados 28 días después de la intervención quirúrgica. El grado de fibrosis peridural se evaluó sobre la columna vertebral de especímenes por análisis histológico. Resultados. Ambos grupos de animales tratados con Oxiplex o Gore-Tex mostraron una reducción significativa en el grado de fibrosis peridural en comparación con el grupo control. Sin embargo, ninguna diferencia significativa en la prevención de la fibrosis peridural se observó entre los grupos de Oxiplex y Gore-Tex. Conclusiones. Este modelo experimental ha demostrado que Oxiplex y Gore-Tex son métodos eficaces para prevenir la fibrosis peridural y adherencias en la duramadre tras laminectomías.
