An aggressive diagnostic work-up to determine the site of bleeding was employed in all 25 patients requiring transfusion of over 1,500 cc of blood for colonic hemorrhage in New Haven in 1977 and 1978. A specific bleeding site that permitted segmental colectomy was found in 23 patients (92 percent). The mortality rate was zero, reflecting the rapid improvement in survival that has occurred in the last decade among patients with massive colonic hemorrhage.
1977年和1978年在纽黑文，对所有因结肠出血而需要输注超过1500cc血液的25例患者都采用了积极的诊断性检查以确定出血部位。在23例患者（92%）中发现了允许进行节段性结肠切除术的特定出血部位。死亡率为零，这反映了过去十年中大量结肠出血患者生存率的迅速提高。
