抄録 [Background and Aim] Usefulness of image enhanced endoscopy (IEE) has been reported for esophagus, stomach and colon. Common indications for balloon-assisted enteroscopy is obscure gastrointestinal bleeding (OGIB). However, it's sometimes difficult to differentiate small lesions, angioectasia or clot or abrasion mark. Narrow band imaging (NBI) shows surface vessels in the mucosa as brown and deeper as green. We reported that angioectasia showed dark green colored area as 'dark green sign' (DG), contrary to abrasion mark or clot showing brown by NBI. We analyzed the usefulness of NBI in diagnosing angioectasias in OGIB cases. [Materials and methods] Between March 2008 and October 2012, 23 cases of angioectasias in small intestine were treated by single balloon enteroscopy (SBE). We divided the detected lesions into two groups, lesions with DG and brown-colored lesions (B), and assessed the results. [Results] In 23 cases, 119 lesions were detected. Of 119 lesions, 61 lesions (51.3%) were DG, while 58 lesions were B. We recognized DG lesion as angioectasia and treated by argonplasma coagulation or clipping. We left lesions in B. Two cases had recurrent bleeding from the same lesion. Two cases had 2nd SBE for another angioectasia. We followed for an average of 18.3 months, and other cases didn't require further treatment. [Conclusion] IEE including enteroscopy with NBI for diagnosis of angioectasia is useful.
