RESUMEN

La fisura anal es una laceración ovoidea del anodermo, cuyo factor desencadenante es la sobredistensión del conducto anal; está asociada con hipertonía del esfínter anal y reducción del flujo sanguíneo, lo que ocasiona una pobre respuesta a la cicatrización. Se han propuesto algunas formas de manejo farmacológico, en virtud de que el tratamiento quirúrgico conlleva a un pequeño riesgo de incontinencia anal leve. Entre los fármacos más utilizados se encuentran: la nitroglicerina, el dinitrato de isosorbide, la nifedipina, el diltiacem y la toxina botulínica. Ante la presencia de una fisura anal severa o cuando el tratamiento farmacológico fracasa está indicado el tratamiento quirúrgico.
