Diagnostic yield and clinical impact of wireless capsule endoscopy in patients with chronic abdominal pain with or without diarrhea: a Greek multicenter study.

Background: Wireless capsule endoscopy has become the gold standard for the examination of small bowel. However, its role in the evaluation of patients suffering from chronic abdominal pain is not yet clearly defined. We conducted an open-label prospective multi-center study to evaluate the yield and clinical outcome of capsule endoscopy in patients with chronic abdominal pain with/without diarrhea.
