Aim: To evaluate prospectively the clinical efficacy and safety of endoscopic hydrostatic balloon dilation in a consecutive cohort of symptomatic intestinal Crohn's disease strictures. Methods: Between September 2003 and December 2008 we performed endoscopic balloon dilations in 37 Crohn's disease patients with 39 intestinal symptomatic strictures (4 naïve and 35 postoperative). Dilations were performed using a Rigiflex through-the-scope balloon. Clinical success rate was claimed if a patient remained asymptomatic and did not require surgery or further endoscopic dilation, following technical success. Actuarial curves of clinical, endoscopic (redilation) and surgical recurrence were obtained by Kaplan-Meier method. Demographic and disease variables were related to the main outcomes. Results: After a mean follow-up of 26.3 months (range, 2-61 months), the long-term global benefit rate was 89% (33/37). The 1-2-3 years cumulative symptom-free rates were respectively: 76%, 55% and 46%. Four patients were operated upon. Technical success predicts a lower rate of surgery. There were no complications related to the endoscopic procedures. Conclusions: Endoscopic balloon dilation of symptomatic Crohn's disease strictures may achieve clinical benefit in many patients and is a valid alternative to surgery in the management of the disease. Dilation may be repeated in recurrent intestinal obstructions and appears safe without morbidity.
