To evaluate percutaneous embolotherapy in the treatment of lower gastrointestinal hemorrhage.
Twenty-one patients who underwent attempted percutaneous embolization for acute lower gastrointestinal bleeding between 1982 and 1997 were retrospectively studied. Hemorrhagic sites included jejunum (n = 4), ileum (n = 4), cecum (n = 4), and the remaining colon (n = 9).
Embolization was not technically possible in four patients (19%). Hemostasis was achieved in 15 patients (71%) with prolonged hemostasis in 10 (48%). All embolizations distal to the cecum resulted in prolonged hemostasis. Three of four patients with jejunal bleeding had recurrent bleeding after apparent successful embolization. Only one of four cecal embolizations achieved prolonged cessation of bleeding. No ischemic complications were identified.
Based on these data, it would appear that the risk of bowel ischemia/infarction in the lower gastrointestinal tract may not be as high as has been suggested. Two regions (cecum and proximal jejunum) were associated with poor results, suggesting these areas may not be as responsive to embolotherapy as other sites in the lower gastrointestinal tract.
评估经皮栓塞疗法在治疗下消化道出血中的应用。
回顾性研究了1982年至1997年间21例因急性下消化道出血而尝试进行经皮栓塞治疗的患者。出血部位包括空肠(4例)、回肠(4例)、盲肠(4例)和其余结肠(9例)。
4例患者(19%)技术上无法进行栓塞。15例患者(71%)实现了止血,其中10例(48%)止血时间延长。所有在盲肠远端的栓塞均导致止血时间延长。4例空肠出血患者中有3例在栓塞明显成功后出现复发出血。4例盲肠栓塞中只有1例实现了出血的长期停止。未发现缺血性并发症。
基于这些数据,下消化道肠缺血/梗死的风险似乎可能不像之前认为的那么高。两个区域(盲肠和空肠近端)治疗效果不佳,表明这些区域对栓塞疗法的反应可能不如下消化道的其他部位。
