Core Tip

Core tip: Benign refractory stricture can be a very challenging pathology, which requires regular endoscopic dilations. Results of this meta-analysis suggest that endoscopic intralesional steroid injection significantly decreases the frequency of the endoscopic dilations in benign refractory esophageal strictures. In addition, there are very few and mild complications reported in association with this method. We believe that the benefits of intralesional steroid in the treatment of benign refractory stricture overweigh its risks. However, further research would be essential on this treatment method, as there are no data concerning its efficacy and safety in different etiologies of refractory esophageal strictures.
