目的分析肝硬化胃底静脉曲张的相关超声测量参数,探讨其诊断价值。方法回顾性分析接受胃镜检查并经临床确诊的肝硬化胃底静脉曲张患者143例的胃肠超声造影图像及参数:胃底静脉最宽处的内径(X1)与流速(X2)和常规超声图像及参数:门静脉主干内径(X3)及流速(X4)、脾门处脾静脉内径(X5)及流速(X6)、脾脏厚度(X7)及长度(X8)。采用logistic回归分析法分析以上所测得参数与肝硬化胃底静脉曲张的相关性及相关性大小。结果轻、中、重三组所得回归方程显示:X1、X3、X7三项参数对肝硬化胃底静脉曲张的诊断价值较大。结论二分类logistic回归模型的建立能够筛选出对肝硬化胃底静脉曲张的诊断有意义的超声测量参数,在肝硬化胃底静脉曲张的超声诊断中具有较好的提示作用。
Objective To analyze the related parameters of gastric varices in patients with cirrhosis and discuss the diagnostic value. Methods Gastrointestinal ultrasonography and parameters of 143 cases of patients with cirrhosis and gastric varices were retrospectively analyzed. The diameter (X1) and velocity (X2) of the widest part of gastric fundus and conventional ultrasound images Parameters: the diameter (X3) and velocity (X4) of portal vein, the diameter of splenic vein (X5), the velocity of flow (X6), the thickness of spleen (X7) and length (X8). Logistic regression analysis was used to analyze the correlation between the parameters measured above and cirrhosis and gastric varices. Results The regression equations of light, medium and heavy groups showed that the three parameters of X1, X3 and X7 were of great value in diagnosing cirrhosis and gastric varices. Conclusion The establishment of dichotomous logistic regression model can screen out the ultrasound parameters which are of significance for the diagnosis of gastric varices in patients with cirrhosis and have a good indication in the diagnosis of gastric varices with cirrhosis.
