电针深刺天枢穴治疗功能性便秘随机对照研究

Observation on therapeutic effect of electroacupuncture at Tianshu (ST 25) with deep needling technique on functional constipation

目的:探寻治疗功能性便秘的较佳疗法。方法:将95例功能性便秘患者随机分为深刺天枢组(48例)、浅刺天枢组(24例)和药物组(23例)。深刺天枢组采用电针深刺天枢穴至腹膜;浅刺天枢组电针天枢穴至皮下5mm;药物组采用杜秘克口服液治疗。3组均连续治疗4周,并随访6个月。观察周排便次数达4次的人数、周排便次数变化差值和便秘评分量表总评分(CCS)变化差值。结果:深刺天枢组在改善周排便次数和周排便次数达4次的人数及降低CCS总评分方面与浅刺天枢组疗效相当(均P>0.05),且均优于药物组(均P<0.05),深刺天枢组较浅刺天枢组和药物组起效更快,疗效更为持久。结论:电针深刺天枢穴治疗功能性便秘疗效与浅刺天枢穴疗效相当,但较浅刺组起效快;两组均优于药物治疗,远期疗效较好。

Objective To probe into a better therapeutic method for functional constipation. Methods Ninety-five cases of functional constipation were randomly divided into deep puncture at ST 25 group （48 cases）, shallow puncture at ST 25 group （24 cases） and medication group （23 cases）. In deep puncture at ST 25 group, Tianshu （ST 25） was punctured deeply to the peritoneum, with electric stimulation. In shallow puncture at ST 25 group, Tianshu （ST 25） was punctured shallowly, 5 mm beneath the skin, with electric stimulation. In medication group, Duphalac was administered orally. These cases were treated continuously for 4 weeks in 3 groups and followed up for 6 months. It was to observe the numbers of person who had defecation 4 times a week, difference in weekly defecation frequency and the difference in the Cleveland Clinic Score （CCS）. Results In deep puncture at ST 25 group, the frequency of weekly defecation and the numbers of person who had defecation 4 times a week increased and CCS decreased, which were similar to the efficacy in shallow puncture at ST 25 group （all P〉0. 05）. But the efficacy of both ST 25 groups was superior to that in medication group （both P〈0. 05）. In comparison, the deep puncture at ST 25 group acted more quickly than either shallow puncture at ST 25 group or medication group and its efficacy remained much longer. Conclusion The deep puncture at ST 25 with electric stimulation presents similar efficacy on functional constipation as shallow puncture at ST 25, but it acts more quickly than shallow puncture at ST 25, both of them are more advantageous than medication and the long-term efficacy is better.
