Angiodysplasia of the gastrointestinal tract is a rare vascular pathology that sometimes causes massive hemorrhage. Angiodysplasias are particularly difficult to find in the small intestine for anatomical reasons, often impeding their diagnosis and treatment. Lesion localization is a major challenge in cases of small bowel bleeding requiring surgical intervention.
The present case was a 52-year-old woman who was urgently hospitalized with repeated tarry stools. Surgical intervention was chosen after conservative treatment failed to improve her condition. The source of bleeding was suspected to be a vascular lesion discovered in the small intestine during a past double-balloon endoscopy. Abdominal contrast computed tomography revealed a jejunal hemorrhage. We chose selective arterial embolization to stabilize her hemodynamics followed by surgical intervention as her treatment plan. Several embolic and contrast agents (cyanoacrylate, indigo carmine, and Lipiodol) were combined to help identify the location of the lesion during surgery. This multi-pronged approach allowed us to localize the lesion under laparoscopic guidance with high confidence and accuracy, and to excise a 6-cm segment of the small intestine. The lesion was histologically diagnosed as angiodysplasia. No re-bleeding has been observed since the operation.
We report our experience with a case of jejunal angiodysplasia, which was localized with selective arterial embolization using an array of embolic and contrast agents, and then excised laparoscopically. Selective arterial embolization with indigo carmine dye to treat small bowel bleeding preoperatively not only makes the surgery safer by stabilizing the patient's hemodynamics, but is also very useful for localizing the lesion intraoperatively.
胃肠道的血管发育不良是一种罕见的血管病理学,有时会导致大量出血。由于解剖学原因,血管发育不良在小肠中特别难以发现,这常常阻碍了它们的诊断和治疗。病变定位是需要手术干预的小肠出血病例的主要挑战。
本病例为一名 52 岁女性,因反复黑便紧急住院。在保守治疗未能改善病情后,选择了手术干预。怀疑出血源是过去双气囊内镜检查中发现的小肠血管病变。腹部对比计算机断层扫描显示空肠出血。我们选择了选择性动脉栓塞以稳定她的血液动力学,然后进行手术干预作为她的治疗计划。在手术过程中,我们结合了几种栓塞剂和对比剂(氰基丙烯酸酯、靛胭脂和碘化油)来帮助识别病变的位置。这种多管齐下的方法使我们能够在腹腔镜引导下高度准确地定位病变,并切除 6 厘米长的小肠段。病变的组织学诊断为血管发育不良。手术后没有再出血。
我们报告了一例空肠血管发育不良的病例,通过使用一系列栓塞剂和对比剂进行选择性动脉栓塞定位,然后腹腔镜切除。术前使用靛胭脂染料进行选择性动脉栓塞治疗小肠出血,不仅通过稳定患者的血液动力学使手术更安全,而且在术中定位病变也非常有用。
