Esfínter artificial para la reconstrucción anorrectal total. Reporte preliminar y revisión de técnica quirúrgica

Abstract

Introduction: The artificial sphincter (ABS) has been proposed as an option for the treatment for severe refractory fecal incontinence. We have witnessed a great discussion on systematic reviews regarding the short-and long-term results of ABS, assessing its real benefit. Objective: To analyze the surgical outcomes of patients undergoing artificial sphincter implantation and review of surgical technique. Material and Methods: Between 2003 and 2007, the ABS system was introduced in four patients. The mean age was 34 years (13 to 54 years). Two patients were admitted for rectal agenesis, a severe anorectal trauma and abdominoperineal resection for a low rectal cancer. Results: Follow-up time was 12 to 60 months. We performed the explantation of the device for perineal wound infection in one case. All patients had mild incontinence ABS showed a decrease an average of 3.5 points to 12 months of follow-up on the Wexner Scale. Conclusions: The installation of the artificial sphincter is a feasible and safe alternative for anorectal reconstruction in selected patients. The morbidity and explantation of the series is similar to other international reports.
