生物反馈对功能性便秘患者症状和心理状态的影响

Effect of Biofeedback Therapy on Clinical Symptoms and Psychological Status in Patients with Functional Constipation

背景:功能性便秘(FC)是一种消化系统常见的功能性胃肠病,生物反馈是其有效治疗方法之一。目的:探讨生物反馈治疗对FC患者临床症状和心理状态的影响。方法:对78例符合FC罗马Ⅱ标准的患者行生物反馈训练,应用症状积分量表、结肠转运时间、Zung焦虑自评量表(SAS)、抑郁自评量表(SDS)等评定患者治疗前后临床症状和心理状态的综合改善情况。结果:生物反馈治疗FC的总有效率为79.5%。生物反馈治疗前,与中国常模相比,FC患者的焦虑(39±8对31±13)和抑郁(52±9对42±11)积分显著升高(P均<0.01)。生物反馈治疗后,患者焦虑(33±7对39±8)和抑郁(46±8对52±9)显著改善(P均<0.01)。结论:生物反馈不仅可改善FC患者的临床症状,还可改善其异常心理状态。

Background： Functional constipation （FC） is one of the common functional gastrointestinal disorders. Biofeedback therapy is one of the effective treatments of FC. Aims： To explore the effect of biofeedback therapy on clinical symptoms and psychological status in patients with FC. Methods： Seventy-eight patients with FC defined by Rome Ⅱ criteria were enrolled and received biofeedback training. Bowel symptoms score, colon transit time, Zung＇s self-rating anxiety scale （SAS） and self-rating depression scale （SDS） were recorded to assess the effects before and after treatment. Results： The overall efficacy rate of biofeedback therapy was about 79.5%. Before biofeedback therapy, score of SAS （39±8 vs. 31±13, P〈0.01） and SDS （52±9 vs. 42±11, P〈0.01） in FC patients were significantly higher than those in Chinese norm. After biofeedback therapy, score of SAS （33±7 vs. 39±8, P〈0.01） and SDS （46±8 vs. 52±9, P〈0.01） improved significantly. Conclusions： Biofeedback therapy can improve not only clinical symptoms, but also the abnormal psychological status in FC patients.
