This study is looking at a new way to perform a procedure called retrograde enteroscopy, which helps doctors look inside your small intestine. They want to see if using a special balloon system called NaviAid with a standard colonoscope (a flexible tube with a camera) can help them reach further into the small intestine compared to using the colonoscope alone. This could help them find the cause of problems like obscure gastrointestinal bleeding (bleeding that isn't easily explained), anemia (low red blood cell count), or iron deficiency. You might be able to join if you are between 18 and 90 years old, need a retrograde enteroscopy, and are medically stable. The study aims to see if using NaviAid helps doctors insert the scope deeper, which could lead to more findings. The current status of this study is unclear.
