摘要
目的:探讨64排螺旋CT对不明原因下消化道出血的诊断价值。方法:回顾性分析2006年7月～2007年1月26例不明原因下消化道出血病例行64排螺旋CT扫描。结果:26例中结肠恶性肿瘤13例(50%),小肠间质瘤4例(15.3%),小肠套叠2例(7.6%),腹股沟斜疝3例(11.5%),肠系膜静脉血栓形成3例(11.5%),肠系膜血管畸形1例(3.8%),均经手术病理证实,其中4例肠系膜血管病变还由DSA证实。本组应用64排螺旋CT病变定位准确率100%,定性诊断正确率97%(1例炎性病变定性不清)。结论:64排螺旋CT对不明原因下消化道出血的定位、定性诊断和指导临床制定治疗方案均具有重要价值。
Objective： To investigate the diagnostic value of 64 multi-detector rows CT for unknown cause of acute lower gastrointestinal bleeding. Methods- Multi-planar reconstruction and CT angiography of 64 multi-detector row CT were prospectively performed in 26 cases of unknown cause of lower gastrointestinal bleeding. Results： All 26 patients were confirmed by pathology including large intestinal tumor, 13 cases （50%）, intestinal tumor, 4 cases （15.3%）, intestinal obstruction, 2 cases （7.6%）, hernia, 3 cases（11.5%）, acute mesenteric venous thrombosis（AMVT）, 3 cases（11.5%）, mesenteric arterio-venous fistula, 1 case（3.8%）. The diagnostic accuracy was 97%, the accuracy of predicting lesion position was 100%. Conclusion： 64 multi-detector rows CT scanning has high value for detecting the cause of intestinal hemorrhage and detecting the site of intestinal lesion.
