| [ Summary ] | When performing emergent colonoscopy in the lower gastrointestinal tract, suspected vascular disorders and prompt determination of pretreatment procedures, based on sufficient patient interviews and physical findings are crucial. If melena is present in a fluid state, it is preferable that no pretreatment or glycerin enema be undertaken in most cases. Sufficient preparation for hemostasis may also be needed because scheduled endoscopic examinations often turn into simultaneous endoscopic treatment. Among the disorders presenting melena, ischemic colitis is highly frequent. It can be relatively easily diagnosed from its characteristic symptoms and endoscopic findings. With the advances in endoscopic evaluation techniques and increasing availability, diagnosis and treatment of arteriovenous malformation (AVM) is on the rise. Apparent bleeding is rarely seen in AVM ; surgical intervention is undertaken in many bleeding cases, but in recent years endoscopic treatment has been performed as well. |
