A 60-year-old male with esophageal cancer underwent endoscopic mucosal resection and thereafter developed esophageal stricture. He was treated with oral steroids and underwent endoscopic balloon dilatation (EBD) several times. The esophageal stricture did not improve after two EBD treatments. Esophageal perforation occurred during the third EBD treatment, and the esophageal muscular layer was rupturv ed. The perforation became larger and a mediastinal abscess that reached the abdomen was observed by a naso-esophageal extraluminal drainage catheter. Therefore, esophageal and mediastinal drainage was performed. The patient was treated with antibiotics and drainage. The perforation closed, but the patient again developed esophageal stricture. A covered removable esophageal stent was placed considering the risk of EBD-induced perforation. The stent was retrieved two weeks after placement without complications. Fifteen months have passed since stent retrieval, and the patient has had no recurrence of esophageal stricture.
