Endoscopic study on colonic angiectasia

Abstract

We have experienced 65 cases of colonic angiectasia which were diagnosed by colonoscopy from 1994 Febrary to 2001 April. The incidence of colonic angiectasia among the total of 12,200 colonoscopy was 0.67%. The patients consisted of 44 males and 21 females with an average age of 60.4 (the age of male was 59.3, the age of female was 62.8) . 42 patients had a single lesion. These were observed in throughout the colon and rectum. 23 patients had the other disorders, for example 15 patients had liver cirrhosis. Only 22 patients had the symptoms (melena, anemia etc) and 70% of 65patients were revealed angiectasia accidentally. The most of them revealed type A which were spider-like appearance. Type B angiectasia were showed the vessel of 1mm in the third layer by endoscopic ultrasonography (EUS) , but type A was not observed vascular shadow by EUS.
We recommend the therapy for type A is argon plasma coagulation, and for type B is clipping.
