Angiodysplasia as a source of intestinal bleeding: report of seven cases.
From October 1978 to April 1991, seven patients presenting at the National Taiwan University Hospital with gastrointestinal tract hemorrhage were diagnosed by colonofibroscopy or angiography as having angiodysplasia of the colon and small intestine. There were two men and five women; their ages ranged from 23 to 65 years, with a mean age of 50.3 years. None of these patients were diagnosed by barium enema. Only two patients were diagnosed by colonofibroscopy, and six patients were diagnosed by angiography. Therefore, angiography was the most effective method for diagnosing angiodysplasia. A vascular tuft was the most frequent finding. Six patients with lesions on the right side of the colon underwent a right hemicolectomy, one patient with a lesion on the jejunum underwent a right hemicolectomy initially with segmental resection of the jejunum later. The postoperative courses were smooth, and there has been no further evidence of gastrointestinal blood loss or anemia in the follow-up period. A right hemicolectomy is the treatment of choice because these lesions are frequently multiple; the lesions are found primarily on the right side of the colon.
