Lower digestive tract bleeding occurs distal to the angle of Treitz. While many cases remit spontaneously; some pose a diagnostic challenge for surgeons. We present the case of a 68-year-old man with unexplained digestive tract bleeding. Despite various diagnostic efforts, the source remained unknown. Faced with the challenge of persistent bleeding and hemodynamic instability, surgery became necessary. During the procedure, intraoperative angiography with indocyanine green was used to facilitate the identification of the bleeding site, revealing a gastrointestinal stromal tumor in the small bowel. Resection was performed with favorable outcomes. Indocyanine green staining has become popular for locating intestinal bleeding during emergency surgeries, aiding surgeons in making precise decisions.
下消化道出血发生在屈氏韧带以下。虽然许多病例可自行缓解，但有些病例对外科医生来说是诊断难题。我们报告一例68岁不明原因消化道出血的男性病例。尽管进行了各种诊断努力，出血源仍不清楚。面对持续出血和血流动力学不稳定的挑战，手术成为必要。手术过程中，使用吲哚菁绿术中血管造影来协助确定出血部位，发现小肠有胃肠道间质瘤。进行了切除手术，效果良好。吲哚菁绿染色在急诊手术中定位肠道出血方面已很常用，有助于外科医生做出精确决策。
