Bleeding from the small intestine may be difficult to diagnose, because of the organ's length and free intraperitoneal location. Although there is a variety of causes of intestinal bleeding, angiodysplasia is the most common. Several different tests can be used to identify the bleeding site preoperatively or intraoperatively, including enteroscopy.
由于小肠的长度以及其在腹腔内的游离位置，小肠出血可能难以诊断。尽管肠道出血有多种原因，但血管发育异常是最常见的。术前或术中可使用几种不同的检查来确定出血部位，包括小肠镜检查。
