[ acupuncture method combined with electroacupuncture for diarrhea-type irritable bowel syndrome : a randomized controlled trial].

OBJECTIVE

To compare the clinical effect between acupuncture method combined with electroacupuncture (EA) and EA alone in the treatment of diarrhea-type irritable bowel syndrome (IBS-D).

METHODS

A total of 76 patients of IBS-D were randomly divided into a Tiaoshen group (38 cases, 2 cases dropped off ) and an EA group (38 cases, 1 case dropped off). The EA group was treated with acupuncture at Guanyuan (CV 4), Zhongwan (CV 12), Tianshu (ST 25), Dachangshu (BL 25), Zusanli (ST 36), Shangjuxu (ST 37), etc. for 30 min. The bilateral Tianshu (ST 25) and the same side of Zusanli (ST 36) and Shangjuxu (ST 37) were connected EA (discontinuous wave, 1 Hz in frequency, 4-6 mA in current intensity). In the Tiaoshen group, the acupuncture method was added on the basis of the EA group. The acupoints were Baihui (GV 20), Shenting (GV 24) and Benshen (GB 13), and the needles were retained for 30 min. Both groups were treated once a day, 6 days as a course of treatment, with an interval of 1 d between treatment courses, and a total of 4 courses of treatment were required. The IBS symptom severity scale (IBS-SSS) score, IBS quality of life scale (IBS-QOL) score and Hamilton depression scale (HAMD) score were observed before and after treatment in the two groups, and the clinical effect was evaluated.

RESULTS

After treatment, the total effective rate in the Tiaoshen group was 94.4% (34/36), which was higher than 78.4% (29/37) in the EA group (<0.05). The IBS-SSS and HAMD scores of both groups after treatment were lower than before treatment (<0.05), while IBS-QOL scores were higher than before treatment (<0.05). Moreover, the changes of above scores in the Tiaoshen group were higher than those in the EA group (<0.05).

CONCLUSION

The acupuncture method combined with EA have a significant effect in treatment of IBS-D, can significantly reduce the symptoms of abdominal pain, abdominal distension and diarrhea in patients, effectively improve patients' quality of life and depression condition, the effect is better than the simple EA treatment.
