Angiodysplasia of the colon: endoscopic diagnosis and treatment

Of 34 patients with massive lower intestinal bleeding, 17 (11 men and 6 women, age range 33-85 years; mean 64.8 years) were diagnosed as having angiodysplasia of the colon. The diagnosis was made by colonoscopy and the lesions were treated successfully by fulguration in 13 (86.6 per cent) of 15 patients. Two of the 17 patients underwent surgical resection of the involved intestinal segment. One patient still has sporadic intestinal haemorrhage, and another patient died from bleeding of the left colon after blind right colectomy. The remaining 13 patients have had no further bleeding in the 1-7 years following colonoscopic fulguration. Colonoscopy is a useful method of diagnosing angiodysplasia of the colon and affords the possibility of treatment.
