血清-腹水蛋白梯度在腹水病因诊断中的价值

Value of serum ascites albumin gradient in the etiological diagnosis of ascites

[目的]探讨血清-腹水蛋白梯度(SAAG)在腹水病因诊断中的价值。[方法]将入诊的80例腹水患者,按腹水形成机制分为门脉高压组(42例)和非门脉高压组(38例),以同天采样同步检查的血清白蛋白浓度和腹水白蛋白浓度计算SAAG,比较2组SAAG与诊断的关系。[结果]门脉高压组的SAAG显著高于非门脉高压组(P<0.01)。[结论]SAAG对诊断腹水有重要价值,但不能完全代替其他检查方法,有时还需要联合监测以提高腹水诊断率。

[Objective]To explore the value of serum ascites albumin gradient （SAAG）in the etiological diagnosis of ascites, l-Methods]We retrospectively analyzed 80 outpatients and inpa- tients with ascites and divided them into portal hypertension related ascites group（42 cases）and non-portal hypertension related ascites group（38 cases）, calculated the SAAG through the con- centration of serum albumin and ascitic albumin taken at the same day, comparing the relationship between diagnosis and SAAG of the two groups. [Results]SAAG of the portal hypertension group was significantly higher than the non-portal hypertension group（P〈0. 01）. [Conclusion]SAAG is valuable for the diagnosis of portal hypertension ascites and non-portal hypertension ascites, how- ever,it cannot completely replace other inspection methods. It is necessary to improve the ascites diagnosis rate together with other inspection methods.
