The implantation of an artificial anal sphincter in five patients with anal incontinence of neuromuscular origin is described. The prosthesis, an AMS 800 artificial urinary sphincter (American Medical Systems), worked well with solid or semisolid stool, but less satisfactorily when diarrhea was present. Manometric and defecographic studies seem to indicate that the effect of the prosthesis may be ascribed partly to maintenance of an acute anorectal angle even during straining.
本文描述了对5例神经肌肉源性肛门失禁患者植入人工肛门括约肌的情况。该假体为AMS 800人工尿道括约肌（美国医疗系统公司），对固体或半固体粪便效果良好，但在出现腹泻时效果欠佳。测压和排粪造影研究似乎表明，该假体的作用可能部分归因于即使在用力排便时也能维持急性肛管直肠角。
