RESUMEN
To evaluate the therapeutic effect of traditional Chinese medicine( TCM) retention enema in treating ulcerative colitis( UC) by Meta-analysis method. Randomized controlled trials( RCTs) of TCM retention enema in treatment of UC were retrieved from databases as CNKI,Wan Fang,CBM,VIP and PubMed from inception to June 2019. The quality of RCTs was assessed by using the Cochrane collaboration's tool for assessing risk of bias,Meta-analysis were performed with Rev Man 5. 3 software and publication bias was tested by using Stata 15. 1 software. There were twenty-eight articles enrolled,and 2 477 patients were included. The result of Meta-analysis showed that retention enema with TCM had significantly better effectiveness in overall curative effect( RRSASP= 1. 18,95%CI[1. 13,1. 22],Z = 8. 32,P < 0. 01; RR5-ASA= 1. 13,95% CI[1. 03,1. 21],Z = 2. 61,P < 0. 01) symptom curative effect( RR =1. 44,95%CI[1. 22,1. 71],Z = 4. 25,P<0. 01) than those of the control group,and the treatment group was lower than the control group in terms of recurrence( RR = 0. 31,95% CI[0. 17,0. 56],Z = 3. 88,P< 0. 01) and adverse events( RR = 0. 38,95% CI[0. 18,0. 78],Z = 2. 64,P<0. 01),with statistically significant differences. However,there was no significant difference in Meta-analysis result of colonoscopic mucosal change between the two groups. TCM enema is an effective method to treat ulcerative colitis.
