Background The short- and long-term results of balloon dilation therapy in Crohn's patients with non-anastomotic obstructive gastrointestinal lesions are investigated.

Materials and methods Fifty-five patients with Crohn's disease who had obstructive gastrointestinal lesions were treated prospectively by endoscopic balloon dilation.

Short-term results Eight of the initial dilations were unsuccessful giving no symptomatic relief (14.5%).

Long-term results The subjects of the long-term prognosis were 40 cases followed up for more than 6 months (average 37 months) and their strictures were non-anastomotic in more than half (59%). Avoidance of surgery, was possible in 31 of 40 patients (78%). Surgery was avoided in 92%, 81% and 77% of patients after one, two, and three years, respectively (Kaplan–Meier's method). There was no difference in long-term outcome between anastomotic strictures and strictures in the absence of prior surgery.

Conclusion Our results suggest that, (1) strictures in the absence of prior surgery might be treated in this way as well as anastomotic strictures; (2) if followed for a prolonged time period, more than 70% of patients, who have undergone balloon dilation for obstructive gastrointestinal Crohn's disease, may be able to avoid surgery.
