Objective To observe the clinical effect of warm needling in the treatment of diarrhea irritable bowel syndrome. Methods One hundred and twenty patients with diarrhea irritable bowel syndrome were randomly divided into a warm needling group and a western medicine group by random digit table method, 60 patients were included in each group. Tiānshū (天枢 ST 25), Zúsānl (足三里 ST 36) and Sānyīnjiāo (三阴交 SP 6) were selected as the main acupoints for the warm needling group, the needles were retained for 30 min, once a day, an interval of 1 day was set up after treatment for six days, and the treatment were carried out for continuous four weeks. The patients in the western medicine group were orally administered with 2 mg loperamide hydrochloride capsules, 3 times a day, and the treatment were carried out for continuous four weeks. The treatment effects were compared between the two groups, and the recurrence rates were counted after for six-month followup. Results The total effective rate in the warm needling group was 86.7% (52/60) and the total effective rate in the western medicine group was 71.7% (43/60), and the difference between the two groups was statistically significant (P0.05); after six-month follow-up, the recurrence rate in the warm needling group was 21.4% (6/28), while the recurrence rate in the western medicine group was 54.5% (12/22), and the difference between the two groups was statistically significant (P0.05). Conclusion The warm needling therapy shows relatively satisfactory treatment effects in the treatment of diarrhea irritable bowel syndrome and the recurrence rate is relatively low. 展开更多
