  1. RBES Refractory benign esophageal strictures
  2. a: Fisher’s exact test
  3. b: The mixed etiology was the patient with RBES caused by caustic injury and esophageal anastomosis following colon surgery
  4. c: P indicates a significant relationship between characteristics of patients and endoscopic therapy in univariate analysis
