This is a randomized two-arms cross-over trial. In this study there are two groups, the control group and the triamcinolone treatment group. The cross-over design will apply only in the control group when patients are not responding to EGD dilations alone (defined as no sustained improvement in baseline dysphagia) and they will be allowed to cross-over to the triamcinolone group and undergo 3 successive EGDs with triamcinolone injection.
