Sixteen patients with gastrointestinal angiodysplasia requiring transfusion were treated with surgical resection, endoscopic electrocautery, or transfusion alone. Pre- and post-therapy transfusion requirements in each group were compared to gauge the efficacy of each therapy. No superiority of any treatment could be shown statistically. The majority of patients had multiple angiodysplastic lesions throughout the gastrointestinal tract, and, accordingly, complete resolution of bleeding after therapy occurred in fewer than one-half of the patients.
16例需要输血的胃肠道血管发育异常患者接受了手术切除、内镜电灼或单纯输血治疗。比较了每组治疗前后的输血需求，以评估每种治疗方法的疗效。统计学上无法显示任何一种治疗方法的优越性。大多数患者在整个胃肠道有多个血管发育异常病变，因此，治疗后出血完全缓解的患者不到一半。
