A 16-year-old male injured in his mouth by firework. 2 month later, esophageal stricture developed and esophageal dilatation using a dilater tube was performed every 2 weeks and 48 times in total. But esophageal dilatation could not be preserved. A flexible artificial esophagus is easy of insert and release, so we tried insertion of this artificial esophagus. 2 month later, we released this artificial esophagus from his esophagus. Since this treatment, his symptom has improved. Treatment of esophageal dilatation using a flexible artificial esophagus is useful for benign esophageal stricture because of easy of insert and release.
