[ Summary ] | Diagnosing vascular lesions associated with obscure gastrointestinal bleeding (OGIB) is difficult even with evaluation performed using capsule/balloon endoscopy. This difficulty may be attributed to the fact that microscopic lesions are challenging to identify, and the source of bleeding cannot be easily detected in the absence of active bleeding. Therefore, in such instances, bleeding may be misdiagnosed as originating from outside the small intestine (extraintestinal lesions). Among the 435 patients with OGIB who underwent balloon-assisted endoscopic examinations since April 2004 at our hospital, 91 patients (20.9 %) (51 men, 40 women, mean age 70.5±5 years) were diagnosed with vascular lesions including bleeding sources outside the small intestine (extraintestinal lesions). Relatively older patients with cardiovascular complications are at a risk of developing vascular lesions attributed to OGIB. Emergency endoscopy performed during an episode of active bleeding is useful for definitive diagnosis. |
