Core Tip

Core tip: Until now, because of the expensive cost and difficult technology, a study of capsule endoscopy (CE) followed by double-balloon enteroscopy (DBE) simultaneously in one case has been rarely reported. To assess the role of CE and DBE in the diagnosis of small bowel diseases, this study was designed to choose the more appropriate examination (between CE and DBE) for obscure small bowel diseases.
