Abstract
Vascular ectasia of the colon and small intestine is recognized as one of the disorder to cause gastrointestinal hemorrhage. However, it is confused that a definition of the term of vascular disorder is not decided. In endoscopy society nomenclature, acquired circumscribed vasodilatation was defined as vascular ectasia or angiectasia, and angiodysplasia or vascular malformation was defined as congenital disorders. Telangiectasia was also defined as genetic disease. Diagnosis of colonic vascular ectasia was as follows findings : strong focal red mucosa, vascular spider like vessels, meander or enlarged vessels. Small intestinal vascular ectasia was detected as active bleeding spot or erosion by capsule endoscope or balloon enteroscopy. In cases of asymptomatic, it was not necessary to active treatment. In cases of bleeding, clipping and coagulated methods such as high frequency current, heater probe and argon plasma coagulation. Argon plasma coagulation method was useful to expect regression of the lesion. In addition, apoplexy source was not clear, and angiography was useful when endoscopic examination was difficult or impossible.
