Endoscopy, barium studies and angiography are all valuable diagnostic procedures in gastrointestinal bleeding. They are not mutually exclusive procedures but the correct sequence of investigation varies. Correct localization can be achieved in 84% of cases of massive gastrointestinal bleeding by their combined use. Vasoconstrictive therapy is also possible in severely ill patients and other poor surgical risk candidates.
内镜检查、钡剂造影和血管造影都是诊断胃肠道出血的重要方法。它们并非相互排斥的检查方法，但正确的检查顺序各不相同。通过联合使用这些方法，84%的大量胃肠道出血病例能够实现正确定位。对于重症患者和其他手术风险高的患者，也可以进行血管收缩治疗。
