Angiodysplasia of the colon is a common cause of lower intestinal tract bleeding. Between February 1974 and May 1983 angiodysplasia was diagnosed in 17 patients, 11 of them since 1980. The sex ratio was 8 men and 9 women with an age distribution of 51 to 87 years (mean 68,6 years), only 3 of them being younger than 60 years. They presented with a history of chronic intermittent gastrointestinal bleeding, massive bleeding (12 %) or chronic iron deficiency anemia (18 %). The bleeding could be bright red (47 %) as well as melena (59 %). An arteriography was performed in 15 patients and demonstrated angiodysplasia in 13 (87 %) ; the 2 patients with a negative arteriography had a colonoscopy with positive biopsies. Two patients underwent no angiography : the first needed an urgent operation because of massive bleeding and in the other the diagnosis was made by colonoscopy. Most angiodysplastic lesions were located in the right colon (14/17). The treatment of choice was a right hemicolectomy; a resection of the sigmoid was performed in 2 patients and endoscopic coagulation in 3 patients.
