Endoscopic exploration of the small bowel after pelvic radiation has limitations related to strong abdominal adhesion. It is often difficult to demonstrate the findings of radiation enteritis endoscopically, even with video capsule endoscopy (VCE) or double-balloon enteroscopy (DBE). We present our experience with three cases of radiation enteritis that were diagnosed using VCE and DBE, including their effective aspects. Radiation enteritis has not been diagnosed using conventional methods, and DBE may not accomplish deeper insertion into the ileum, although it is capable of both diagnosis and hemostasis. Therefore, VCE is thought to be the initial tool for the diagnosis of radiation enteritis when small bowel stenosis has not been previously detected and the risk of retention has been discussed.
