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.
作者旨在报告磁肛门括约肌（MAS）植入的概念和技术，以及其在治疗粪便失禁（FI）中的临床应用的初步结果。MAS 装置旨在增强天然肛门括约肌。植入物由一系列带有磁芯的钛珠组成，通过独立的钛丝连接在一起。为了排便，用力产生的力量将珠子分开，从而打开肛门通道。植入技术简单，无需调整。MAS 在严重 FI 的治疗中有一定作用。该设备的不良反应可接受且与其他治疗方法相当。FI 和粪便失禁生活质量评分在短期内显著改善。MAS 为肛门加强提供了一种简单且微创的选择。这是对理想人工肛门括约肌装置的进一步探索。
