Fifty patients with anal incontinence were treated by biofeedback as an office procedure. This took the form of an intra-anal plug, containing two ring electrodes and connected to an electromyometer. In four or less sessions, patients were instructed in sphincter contraction and extraneous muscle relaxation. All have been followed for at least one year, and in 74 per cent there has been satisfactory restoration of continence. The method was particularly successful in post-surgical (anal) patients, with the exception of those with "keyhole deformity" after anal fistulectomy. In nonsurgical patients, results were excellent in the idiopathic and postradiation groups, but were poor in patients with incontinence due to rectal prolapse or to neurogenic causes. The simplicity and portability of this method make it a valuable aid in the office management of anal incontinence.
五十例肛门失禁患者接受了生物反馈治疗，作为门诊治疗手段。治疗采用肛门内置栓形式，该栓包含两个环形电极并连接到肌电仪。在四次或更少的疗程中，指导患者进行括约肌收缩和无关肌肉放松。所有患者均已随访至少一年，74%的患者失禁情况得到了满意恢复。该方法在术后（肛门）患者中特别成功，但肛瘘切除术后出现“锁孔畸形”的患者除外。在非手术患者中，特发性和放疗后组的效果极佳，但直肠脱垂或神经源性原因导致失禁的患者效果较差。该方法的简单性和便携性使其成为门诊治疗肛门失禁的宝贵辅助手段。
