A Randomised controlled trial comparing the Efficacy and Clinical Outcomes of Single and Double Balloon Enteroscopy in patients referred for Balloon Enteroscopy for investigation or treatment of small bowel conditions.

This study is comparing two instruments used to examine and treat conditions of the small intestine: single-balloon enteroscopy and double-balloon enteroscopy. Both involve passing a long flexible tube down through the mouth or up through the bowel to reach the small intestine, which is otherwise hard to access. Researchers want to find out which technique reaches more of the small bowel, gets better results, and has fewer complications. You may be eligible if: - You are 18 years or older - You have a clinically accepted reason to have a balloon enteroscopy - You are willing to participate You may NOT be eligible if: - You have any medical reason (contraindication) that makes balloon enteroscopy unsafe for you Talk to your doctor about whether this trial might be right for you.
