OAK BROOK, Ill. – November 24, 2008 – A cost-effectiveness analysis conducted by researchers at Stanford University Hospital in Calif., shows that an initial double-balloon enteroscopy (DBE) is a cost-effective approach for patients with obscure gastrointestinal (GI) bleeding. However, capsule-directed DBE (which is when the findings from an initial small bowel capsule endoscopy exam are used to guide the DBE procedure) may be preferred as the initial test due to the potential for fewer complications and decreased utilization of endoscopic resources. The study appears in the November issue of GIE: Gastrointestinal Endoscopy, the monthly peer-reviewed scientific journal of the American Society for Gastrointestinal Endoscopy (ASGE).
