RELACIÓN ENTRE EL GRADO DE INCONTINENCIA FECAL Y EL DAÑO DEL ESFÍNTER ANAL EXTERNO

Introduction: Faecal incontinence (FI) represents an important psychological and social condition for an individual. There are several causes for FI, therefore its study and management is complex. Among different aetiologies, anatomical disruption of the external anal sphincter (EAS) as a consequence of anorrectal surgery or obstetric injury can be studied by endoanal ultrasound (EAUS). This study focus on anatomical assessment of sphincter muscle injury of EAS and its relationship with clinical presentation con FI. Objective: Compare anatomical and disruption of EAS features studied by 3D-EAUS between patients with FI, according to its severity. Methods: 3D-EAUS images were obtained from selected patients studied for FI between January 2008 and July 2010 at Clinica las Condes. Wexner Score (SW) was used to evaluate severity of FI, dividing patients into two categories: Mild FI (SW Introduccion: La incontinencia fecal (IF) se refleja en una condicion psicologica y social importante para el individuo. Las causas de IF son multiples, siendo su estudio y manejo complejo. La disrupcion anatomica del esfinter anal externo (EAE), secundaria, entre otras, a cirugia anorrectal o lesion obstetrica, es posible de ser estudiada por endosonografia anal (EAUS). El presente articulo se centra en el dano anatomico del EAE y su relacion con la presentacion clinica de la IF. Objetivo: Comparar las caracteristicas anatomicas y dano del EAE objetivadas mediante endosonografia en 3 dimensiones (EAUS3D), entre los pacientes con IF segun su severidad. Material y Metodo: Se obtuvo las EAUS3D realizadas en Clinica Las Condes por estudio de IF entre enero de 2008 y julio de 2010. Se utilizo el score de Wexner (SW) para separar la poblacion en dos grupos, IF leve (SW
