Meta analysis of clinical efficacy of acupoint application in the treatment of irritable bowel syndrome
Abstract
Purpose: The clinical efficacy of acupoint application in the treatment of irritable bowel syndrome (IBS) was evaluated by Meta-analysis.
Method: Computer searched Chinese and English databases for the randomized controlled trials (RCTs) and quasi-randomized controlled trials (CCTs) of TCM external therapy, acupoint application, TCM external application, navel sticking and their combination therapy in the treatment of IBS. The search period is from the establishment of the database to December 2022. The literature was screened independently by 2 researchers according to the standard of nano-ranking, and the data of the other 5 researchers were proofread, screened and extracted. After that, the bias risk of the included study was evaluated, and the data were analysed by RevMan 5.4. software.
Result: (1) A total of 1842 patients, were included in 25 randomized controlled trials, including the acupoint application treatment group (n=928) and conventional therapy control group (n = 914).
(2) The quality of the literature method shows that there are 5 high-quality literatures with a score of 4-7, 20 low-quality literatures with a score of 1-3 and few high-quality literatures;
(3) In terms of effectiveness, compared with the western medicine control group, the total odds ratio OR [95 % CI] of the total effective rate of the acupoint application treatment group was 4.77 [3.68, 6.20], and the difference was statistically significant (P < 0.05). Shenque, Zhongwan, Pishu and Zusanli are the most commonly used.
(4) In terms of literature bias, 2 studies used envelopes to hide, which belonged to "low risk"; 9 studies were blindly implemented and evaluated as "unclear"; and 6 studies were rated as "high risk" because cases fell off but were not reported. The funnel plot shows that the study is scatter symmetrical, the probability of publication bias is small, and the conclusion is reliable.
Conclusion: Acupoint application can improve the effective clinical rate of IBS with fewer adverse reactions, better patient compliance and fewer adverse reactions, but it still needs to be confirmed by high-quality multicenter, large sample randomized controlled trials.
