Twenty nine patients, aged 5-16 years, were studied to evaluate whether biofeedback training is effective in treating children with chronic constipation and encopresis; the clinical outcome at six weeks and 12 months was also evaluated. Patients received on average five biofeedback training sessions. The existence of external anal contraction or decreased rectal sensation in 16 (55%) and eight (27%) of the children, respectively was identified on manometry. After biofeedback training, 26 (90%) of the patients learned to relax the external anal sphincter; 18 (63%) normalised rectal sensation. The training resulted in a significant increase in defecation frequency and a significant decrease in encopresis. At six weeks, 16 (55%) of the patients were clinically symptom free. At follow up after 12 months the results were sustained. Only three patients showed a relapse within six months, of whom two were successfully treated with one extra training session. Biofeedback training might be a useful therapeutical approach in children with chronic constipation and encopresis.
对29名年龄在5至16岁的患者进行了研究，以评估生物反馈训练对治疗慢性便秘和大便失禁儿童是否有效；同时还评估了6周和12个月时的临床结果。患者平均接受了5次生物反馈训练。测压结果显示，分别有16名（55%）和8名（27%）儿童存在肛门外括约肌收缩或直肠感觉减退。经过生物反馈训练后，26名（90%）患者学会了放松肛门外括约肌；18名（63%）患者的直肠感觉恢复正常。训练使排便频率显著增加，大便失禁显著减少。6周时，16名（55%）患者临床症状消失。12个月随访时，结果得以维持。只有3名患者在6个月内复发，其中2名患者通过额外一次训练成功治愈。生物反馈训练可能是治疗慢性便秘和大便失禁儿童的一种有效治疗方法。
