[A case of congenital esophageal stenosis that remained untreated until adulthood and was improved by endoscopic balloon dilatation].

ABSTRACT

A 20-year-old man had suffered from dysphagia since primary school. Upper gastrointestinal and endoscopy examinations revealed severe circumferential stenosis of the upper intra-thoracic esophagus. Secondary stenosis due to factors such as inflammation did not appear present, so congenital esophageal stenosis (CES) was diagnosed. Dysphagia improved after two endoscopic balloon dilatations. Almost all cases of CES are treated in baby-hood, and individuals who remain untreated until adulthood are rare. Check ups and diagnoses should be made taking CES into consideration, even in adults.
