【摘要】：目的探讨肠系膜上静脉内径在门静脉高压性胃肠病(PHGE)诊断中的应用价值。方法用螺旋CT测量并比较30例正常人(对照组)和46例PHGE患者(观察组)脾静脉开口下方1.0 cm处肠系膜上静脉内径,采用ROC曲线分析最佳诊断阈值。结果观察组、对照组肠系膜上静脉内径分别为(1.44±0.37)、(0.99±0.24)cm,观察组明显大于对照组,P0.05。通过ROC曲线获得肠系膜上静脉内径最佳诊断阈值为1.2 cm,以此阈值诊断PHGE敏感度为88.0%,特异度为83.3%。结论 PHGE患者肠系膜上静脉内径增大,测量肠系膜上静脉内径有助于早期诊断PHGE。
[Abstract]:Objective to evaluate the value of superior mesenteric vein diameter in (PHGE) diagnosis of portal hypertension gastroenteropathy. Methods the internal diameter of superior mesenteric vein was measured by spiral CT in 30 normal subjects (control group) and 46 patients with PHGE (observation group). The superior mesenteric vein diameter was measured at 1. 0 cm below the opening of splenic vein. The best diagnostic threshold was analyzed by ROC curve. Results the internal diameter of superior mesenteric vein in the observation group and the control group was (1.44 卤0.37), (卤0.99 卤0.24) cm, significantly larger than that in the control group (P 0.05). The optimal diagnostic threshold of superior mesenteric vein diameter was 1.2 cm, by ROC curve. The sensitivity and specificity of the threshold for diagnosis of PHGE were 88.0 and 83.3 respectively. Conclusion the internal diameter of superior mesenteric vein in patients with PHGE is enlarged. Measuring the internal diameter of superior mesenteric vein is helpful for early diagnosis of PHGE..
