To search in retrospectively and prospectively from the efficacy of biofeedback training in patients with fecal incontinence and to investigate the determinant factors of improvement of the patients.
The incontinent patients were evaluated in phases: I: In 37 subjects, 14 men and 23 women, aged between 13 and 82 years, biofeedback training was done, and the efficacy was determined retrospective form. II: In 14 patients, 2 men and 12 women, aged between 19 and 79 years, biofeedback training was done, and rectal balloon sensitivity, force of contraction and motor/sensitivity index were evaluated in prospective form before and after biofeedback training.
In the group of the patients studied in phase I, findings were: 21 patients (60%) complete continence, 12 (34%) improvement, and 2 (5.7%) without change. In the group of the patients studied in phase II, findings were: 8 patients (57%) complete continence, 4 (29%) improvement and 2 (14%) without change. In patients with complete continence there was a decrease in rectal balloon sensitivity (P < 0.05) and an increase of the motor/sensitivity index (P < 0.05), before and after biofeedback training.
Biofeedback is a simple, painless and effective treatment for patients with fecal incontinence. It allows to improve rectal sensitivity and to increase the motor/sensitivity index, determinant for patients continence.
回顾性和前瞻性地研究生物反馈训练对大便失禁患者的疗效，并探讨患者病情改善的决定因素。
对大便失禁患者分阶段进行评估：第一阶段：37名受试者，14名男性和23名女性，年龄在13至82岁之间，接受生物反馈训练，并以回顾性方式确定疗效。第二阶段：14名患者，2名男性和12名女性，年龄在19至79岁之间，接受生物反馈训练，并在生物反馈训练前后以前瞻性方式评估直肠气囊敏感性、收缩力和运动/敏感性指数。
在第一阶段研究的患者组中，结果如下：21名患者（60%）完全控便，12名（34%）病情改善，2名（5.7%）无变化。在第二阶段研究的患者组中，结果如下：8名患者（57%）完全控便，4名（29%）病情改善，2名（14%）无变化。在完全控便的患者中，生物反馈训练前后直肠气囊敏感性降低（P<0.05），运动/敏感性指数升高（P<0.05）。
生物反馈是一种治疗大便失禁患者的简单、无痛且有效的方法。它能够改善直肠敏感性并提高运动/敏感性指数，这是患者控便的决定因素。
