Outcome and complications of endoscopic balloon dilatations in various types of ileocaecal and colonic stenosis in patients with Crohn's disease.

Aim: We examined the outcome and the complications of endoscopic balloon dilatation (EBD) of ileocaecal and colonic strictures due to Crohn's disease.
Methods: We examined 237 dilatation procedures in 77 patients with symptomatic ileocaecal and colonic stenosis regarding outcome, individual perforation risk, the need for further interventions, and other complications within a 10 years observation period.
Results: In 50 of 77 patients (64.9%), endoscopic dilatation procedures were successful within a median follow-up period of 24 months (25th and 75th percentile 10-38.5 months). Thirty five patients (45.5%) were successfully dilated with only one endoscopic procedure, while the remaining patients required two or more EBDs. Albeit the EBD, 27 patients of the whole cohort (35.1%) underwent surgical repair of the stenosis in due course. Overall complication rate was 7.6%, with postdilatation bleeding in 1.7% and abdominal pain longer than 24 h in 4.2%. Perforation occurred in 4 of 77 patients (5.2%), resulting in a perforation rate of 1.7% per intervention, or, more importantly, for the individual patient in a long-term perforation rate of 5.2% per patient, respectively.
Discussion: Endoscopic balloon dilatation (EBD) is a safe and effective approach to ileocaecal and colonic stenosis in approximately 65% of Crohn's disease patients. Even in case of recurrence, further endoscopic treatments can be undertaken. The perforation rate depending on the number of interventions is low, but for the individual patient a cumulative per patient perforation risk of 5.2% in the long-term should be considered during patient information and decisions for or against surgical interventions.
