Following the data extraction, meta-analytical calculations were performed on measures of outcome by the randomeffects method of Der Simonian and Laird. Heterogeneity of the studies was tested by Cochrane's Q and I^2 statistics. Risk of quality and bias was assessed by the Newcastle Ottawa Scale and JADAD assessment tools.RESULTS Eleven articles were identified suitable for analyses, involving 343 patients, 235 cases and 229 controls in total. Four studies used crossover design with 121 subjects enrolled. The periodic dilation index(PDI) was comparable in 4 studies, where the pooled result showed a significant improvement of PDI in the steroid group(MD:-1.12 dilation/month, 95% CI:-1.99 to -0.25 P = 0.012; I^2 = 74.4%). The total number of repeat dilations(TNRD) was comparable in 5 studies and showed a non-significant decrease(MD:-1.17, 95%CI:-0.24-0.05, P = 0.057; I^2 = 0), while the dysphagia score(DS) was comparable in 5 studies and did not improve(SMD: 0.35, 95%CI:-0.38, 1.08, P = 0.351; I^2 = 83.98%) after intralesional steroid injection.CONCLUSION Intralesional steroid injection increases the time between endoscopic dilations of benign refractory esophageal strictures. However, its potential role needs further research.展开更多
