Abstract
ObjectiveTo assess the efficacy and safety of retention enema with traditional Chinese medicine (TCM) for ulcerative colitis (UC) through a meta-analysis of published studies. MethodsLiteratures were retrieved from five electronic databases. Quality evaluation and meta-analysis were respectively conducted using the Cochrane collaboration and RevMan5.3. Overall quality of evidence was evaluated using GRADE system. Effect sizes were pooled using random effect models. ResultsSeventeen RCTs were included. Compared with routine pharmacotherapies (RPs), TCM enema exhibited a statistically significant difference in clinical efficacy and reduction of the recurrence rate. The results of qualitative description for other endpoints, such as improvements in anabrosis, ulcer, diarrhea, and hematochezia, suggested that TCM enema had better efficacy than RPs. Furthermore, the incidence of side effects in TCM was lower than that in RPs. ConclusionThis meta-analysis confirmed the efficacy and safety of TCM enema for improving UC symptoms. However, further well-designed researches are needed.
