目的探讨两类功能性便秘(FC)行生物反馈治疗的效果及随访结果。方法 63例FC患者为研究对象,其中STC(慢传输型便秘)33例,为A组,OOC(出口梗阻型便秘)30例,为B组,均接受生物反馈治疗,比较两组治疗前后肛管静息压、肛管最大收缩压,同时随访6个月比较两组疗效。结果两组治疗后肛管最大收缩压[(108.34±21.30)mm Hg VS(146.75±24.50)mm Hg(1 mm Hg=0.133 k Pa)]比较差异有统计学意义(P<0.05)。另外随访6个月,A组总有效率78.79%,与B组的86.67%比较差异无统计学意义(P>0.05)。结论生物反馈治疗对OOC的疗效相比STC更佳。
Objective To investigate the effect and follow-up of biofeedback in two types of functional constipation (FC). Methods Sixty-three patients with FC were studied. Among them, 33 cases of STC (slow transit constipation) were group A, 30 cases of OOC (outlet obstruction constipation), and group B received biofeedback treatment. Tube resting pressure, anal maximum systolic blood pressure, while 6-month follow-up comparison of the two groups. Results The maximal systolic pressure of the anal canal in the two groups was statistically significant (P <0.05) after treatment (108.34 ± 21.30 mm Hg vs 146.75 ± 24.50 mm Hg (1 mm Hg = 0.133 k Pa)]. In addition, for a follow-up of 6 months, the total effective rate in group A was 78.79%, which was not significantly different from that in group B (86.67%, P> 0.05). Conclusions Biofeedback is more effective in treating OOC than STC.
