Objective: To systematically evaluate the clinical efficacy of acupuncture for peptic ulcer.
Methods: Randomized controlled trials of acupuncture for peptic ulcer were searched from China National Knowledge Infrastructure (CNKI), WanFang Database, Chinese Scientific and Technological Journals (VIP), China Biomedicine (CBM), PubMed and the Cochrane Library from the establishment time of databases to September, 2016. Data extraction and quality evaluation were implemented for the literature which met the inclusive criteria. The RevMan 5.3 software was used to make Meta-analysis.
Results: Sixteen papers including 1 570 patients of peptic ulcer were included. The results of Meta-analysis showed that there was no statistical significance between acupuncture and western medicine in the effective rate, the healing rate of ulcer area and the HP negative rate (all P>0.05); the recurrence rate of acupuncture was significantly lower than that of western medicine[RR=0.35, 95%CI (0.14, 0.84), P<0.05]. Acupuncture plus western medicine was significantly different from simple western medicine in the effective rate, the healing rate of ulcer area and the recurrence rate[RR=1.20,95% CI (1.04, 1.38), P=0.01; RR=1.29, 95% CI (1.06, 1.58), P=0.01;RR=0.27, 95% CI (0.16, 0.45), P<0.00001]. The analysis of evidence grade (GRADE) pre-sented that the healing rate of ulcer area and the HP negative rate of acupuncture were "low grade", and others were "extremely low grade".
Conclusions: Acupuncture combined with western medicine has some advantages for peptic ulcer compared with the conventional western medicine, which needs further confirmation due to the lower evidence grade. Larger samples, randomized controlled trials with high quality are highly recommended.
