Esophageal variceal hemorrhage is a devastating complication of portal hypertension that occurs in approximately one-third of cirrhotic patients.
We assessed the value of the platelet count/ bipolar spleen diameter ratio as a noninvasive parameter for the prediction of esophageal varices (EVs) in Egyptian cirrhotic patients.
Laboratory and ultrasonographic and imaging variables were prospectively evaluated in 175 patients with liver cirrhosis. All patients underwent upper gastrointestinal endoscopy. Patients with active gastrointestinal bleeding at the time of admission were excluded.
The platelet count/ bipolar spleen diameter ratio in patients with EVs was significantly lower than in patients without EVs. In an analysis of the receiver operating characteristic curves (ROCs), we calculated an optimal cutoff value of 939.7 for this ratio, which gave 100% sensitivity and negative predictive values, 86.3% specificity, a 95.6% positive predictive value, and an area under the ROC curve of 0.94 ± 0.02, reflecting its overall diagnostic accuracy. These findings were extended to a subset analysis of compensated cirrhotic patients.
The platelet count/ bipolar spleen diameter ratio has excellent accuracy in the noninvasive assessment of EVs in patients with compensated or decompensated liver cirrhosis. It is easy to calculate and can lower the financial and sanitary burdens of endoscopy units, especially in developing countries.
食管静脉曲张出血是门静脉高压的一种严重并发症,约三分之一的肝硬化患者会出现这种情况。
我们评估了血小板计数/脾脏双径比作为埃及肝硬化患者食管静脉曲张(EVs)预测的非侵入性参数的价值。
对175例肝硬化患者的实验室、超声和影像学变量进行前瞻性评估。所有患者均接受上消化道内镜检查。排除入院时存在活动性胃肠道出血的患者。
有食管静脉曲张的患者的血小板计数/脾脏双径比显著低于无食管静脉曲张的患者。在对受试者工作特征曲线(ROC)的分析中,我们计算出该比值的最佳截断值为939.7,其灵敏度和阴性预测值为100%,特异性为86.3%,阳性预测值为95.6%,ROC曲线下面积为0.94±0.02,反映了其总体诊断准确性。这些发现扩展到了代偿期肝硬化患者的亚组分析。
血小板计数/脾脏双径比在代偿期或失代偿期肝硬化患者食管静脉曲张的非侵入性评估中具有出色的准确性。它易于计算,可减轻内镜检查科室的经济和卫生负担,尤其是在发展中国家。
