Double-balloon enteroscopy-assisted dilatation avoids surgery for small bowel strictures: A systematic review

摘要

AIM To evaluate the therapeutic role of double-balloon enteroscopy(DBE) in small bowel strictures and to propose a standard approach to small bowel strictures.METHODS Systematic review of studies involving DBE in patients with small bowel strictures. Only studies limited to small bowel strictures were included and those with ileo-colonic strictures were excluded. RESULTS In total 13 studies were included,in which 310 patients were dilated. The average follow-up time was 31.8 mo per patient. The complication rate was 4.8% per patient and 2.6% per dilatation. Surgery was avoided in 80% of patients. After the first dilatation,46% were treated with re-dilatation and only 17% required surgery.CONCLUSION DBE-assisted dilatation avoids surgery in 80% of patients with small bowel strictures and is safe and effective. We propose a standardized approach to small bowel strictures.
