In this case, the patient was initially treated with bougie dilatation. During the dilatation process, we started with a 7-mm bougie according to the degree of stenosis, and then increased the diameter of dilatation step by step to expand the stenosis to the maximum extent possible, and then decided to terminate the diameter of the bougie according to the patient’s condition. We found that the strict implementation of these procedures helped prevent complications and avoid restenosis after therapy. The shortest remission time with oral hormone therapy may be related to the Koebner[15] phenomenon, which can induce ulcers, affect wound healing, and let to proliferate faster since scar constitution. For complex benign esophageal strictures, ERI has been observed to have a longer remission time and better efficacy than other endoscopic therapies in clinical practice and can be the therapy of choice.
