Patients and methods: Descriptive and analytical studies based on the retrospective collection of data on 125 patients’ records in the hepatogastroenterology unit of the University Hospital Campus of Lome (Togo) from January 1, 2008 to March 31, 2018 were included. Cirrhotic patients aged 15 years and older had performed cytochemical analysis of ascites fluid and upper gastrointestinal fibroscopy and had a protidogram. Statistical analysis was done by R Studio Software 3.4.2. Results: The mean age was 48.70 years;there was a male predominance (70.40%) with a sex ratio of 2.38. Protein levels in ascitic fluid was Conclusion: Our study noted that at an upper threshold of 1.10 g/dl, the SAAG significantly predicted the presence of EV.展开更多
目的:探讨血清腹水白蛋白梯度(serum-ascites albumin gradient,SAAG)与肝硬化食管静脉曲张程度之间的相关性.方法:收集诊断明确的肝硬化合并腹水患者,根据食管静脉曲张程度分为无或轻度组、中度组和重度组,采用单因素方差分析、相关分...目的:探讨血清腹水白蛋白梯度(serum-ascites albumin gradient,SAAG)与肝硬化食管静脉曲张程度之间的相关性.方法:收集诊断明确的肝硬化合并腹水患者,根据食管静脉曲张程度分为无或轻度组、中度组和重度组,采用单因素方差分析、相关分析、构建受试者工作特征曲线(receiver operating characteristic,ROC)曲线等方法进行统计学分析.结果:共纳入43例患者,单因素方差分析显示3组之间存在显著差异(F=26.317,P<0.001),Spearman相关系数r=0.759,P<0.001,提示SAAG与食管静脉曲张具有正向相关性.构建ROC曲线得到曲线下面积为0.926,当SAAG取值为20.5g/L时是诊断中重度食管静脉曲张的最佳界值,此时敏感度为87.1%,特异度为83.3%.结论:SAAG与食管静脉曲张具有较好的相关关系,该指标对于中重度食管静脉曲张具有诊断价值.展开更多
