Endoscopic balloon dilatation of oesophageal and colonic strictures is now widely performed. Duodenal strictures due to Crohn's disease represent a difficult clinical problem as surgical intervention is a major undertaking and recurrences are common. We describe endoscopic balloon dilatation in three patients with obstructive symptoms from duodenal strictures due to Crohn's disease. The procedure appeared safe, was well tolerated and resulted in an excellent symptomatic response. This method is particularly suitable for short duodenal strictures and avoids the need for surgical intervention in this difficult group of patients.
