Brief Summary in Scientific Language

This randomised, multi centric, and prospective pilot study evaluates the treatment of benign oesophagus stenosis with Bougie Cap (Ovesco, Tübingen, Germany) versus standard therapy with Savary bougies or balloon dilatation in children. A successful treatment is defined as opening the stenosis by dilatation and passing though the stenosis. After informed consent and randomisation the patients were dilated either by the Bougie Cap method or the common standard treatment of the center. Patients and caregivers are blinded. Efficacy, complications, dysphagy score and quality of life are documented during the study.
