摘要
目的 对功能性便秘盆底肌功能紊乱患者进行肛管动力学检查 ,了解其动力学特点 ,探索非药物治疗肛直肠动力异常所致排便困难的临床疗效。方法 32例本病患者 ,行 2 4小时不透X线标志物胃肠道通过时间(GITT)及肛肠测压 ,选择生物反馈治疗 ,疗程 1月 ,每周 2～ 3次。结果 2 4小时GITT :钡条排除率 2 0 2 %。肛肠测压 :直肠感知阀值增高 ,最大耐受量增大 ,肛直肠抑制反射阀值提高。直肠电和盆底肌电评估 :均出现腹前斜肌—盆底肌的矛盾运动 ,且收缩幅度明显降低。生物反馈治疗后便秘患者每周自主排便次数由治疗前 0 8± 0 3提高到 3 8± 1 1,其中 10例患者随访 1年 ,8例每周排便次数恢复正常。治疗后全部患者盆底肌与腹前斜肌矛盾运动消失 ,且运动幅值增加 >5 0mmHg。 结论 功能性便秘盆底肌功能紊乱患者存在肛直肠动力异常 ,有腹前斜肌与盆底肌的矛盾运动。生物反馈治疗后矛盾运动消失 ,每周排便次数增加。
Objective To study the changes of anorectal motility in functional constipation and pelvic floor disorders,and to evaluate the physiologic benefits of biofeedback therapy according to noninvasive electromyography parameters.Methods 35 patients were entered this study.Each had 24h GITT,anorectal manometry and biofeedback therapy.Results (1)The rectal maximal volume of tolerance and the rectal lowest volume of sensory threshold were higher than HS.(2)After biofeedback therapy,96.5 percent of cases demonstrated symptomatic improvement,and the puborectal spasm was disappeared.Conclusion There are some anorectal motility disturbances in functional constipation,and biofeedback therapy is effective in improving symptoms and anorectal function.
