title: The magnetic anal sphincter: a new device in the management of severe fecal incontinence.
abstract: The authors aim to report the concept and technique of implantation and the first results of the clinical use of the magnetic anal sphincter (MAS) in the management of fecal incontinence (FI). The MAS device is designed to augment the native anal sphincter. The implant is a series of titanium beads with magnetic cores linked together with independent titanium wires. To defecate, the force generated by straining separates the beads to open up the anal canal. The technique of implantation is simple with no requirement of adjustments. The MAS has a role in the management of severe FI. The device has acceptable and comparable adverse effects to other therapies. FI and Fecal Incontinence Quality of Life scores are significantly improved in the short term. The MAS offers a simple and less invasive option of anal reinforcement. It is one step further in the quest for an ideal artificial anal sphincter device.
