Endoscopic balloon dilation of colonic and ileo-colonic Crohn's strictures: long-term results.

The long-term effects of endoscopic dilation of colonic or ileo-colonic Crohn's disease strictures were analyzed. In 18 patients with a Crohn's disease-related low gastrointestinal stricture, the stenosis was dilated using through-the-scope (TTS) balloon catheters. A dilation to a diameter of 18 mm was always attempted. Treatment was successfully carried out in 16 patients, and was followed by immediate symptomatic relief in 14 patients. Long-term success was observed in nine patients. There were no complications. Balloon catheter dilation of a colonic stricture or stricture of an ileo-colonic anastomosis was found to be safe and effective. This treatment modality can be an alternative to surgery in a selected group of patients.
