In patients with occult lower gastrointestinal bleeding, locating of the source of the hemorrhage can be quite difficult. While multiple diagnostic tests may confirm a small bowel source of bleeding, precise localization allowing a directed, conservative surgical resection may be problematic. We describe three patients each of whom presented with hemorrhage from the small intestine. The preoperative use of highly selective angiographic catheter placement combined with intraoperative methylene blue dye injection allowed us to precisely locate the source of hemorrhage and to resect a conservative length of small intestine. This technique has been successful in the three patients herein, and we believe that it should be included in the options available to the surgeon.
在隐匿性下消化道出血患者中，确定出血源可能相当困难。虽然多项诊断检查可能证实小肠为出血源，但要精确定位以进行有针对性的保守性手术切除可能存在问题。我们描述了三名小肠出血患者。术前使用高选择性血管造影导管置入并结合术中注射亚甲蓝染料，使我们能够精确确定出血源，并切除一段保守长度的小肠。该技术在本文的三名患者中均取得成功，我们认为它应被纳入外科医生可选用的方法之中。
