目的探讨利用脾脏大小指数(sp len ic index,SI)来预测食管静脉曲张的程度及食管静脉破裂出血的可能性。方法肝硬化患者36例,均行内窥镜及CT检查。通过CT片测量脾脏大小计算SI,内窥镜观察食管静脉曲张的程度。结果(1)SI与食管静脉曲张程度之间呈显著正相关r=0.776P=0.001;(2)SI与肝硬化代偿及失代偿期之间有显著性差异(P=0.004);(3)SI与肝硬化有无出血之间亦有差异(P=0.029);(4)SI与肝硬化有无食管静脉曲张之间有差异(P=0.031);(5)SI与性别,年龄及肝硬化有无腹水之间无相关关系。当SI>940.42 cm3时,肝硬化患者有食管静脉曲张的可能性大。结论SI对预测高危食管静脉曲张有一定价值。SI值较大时提示有食管静脉曲张破裂出血的危险。
Objective To explore the prediction of the degree of esophageal varices and the possibility of esophageal variceal bleeding by splenic index (SI). Methods Thirty-six patients with cirrhosis were examined by endoscopy and CT. The size of the spleen was measured by CT slice SI, endoscopic observation of esophageal varices. Results (1) There was a significant positive correlation between SI and the degree of esophageal varices (r = 0.776 P = 0.001). (2) There was a significant difference between SI and decompensation of liver cirrhosis (P = 0.004) 3) There was also a significant difference between SI and liver cirrhosis with or without bleeding (P = 0.029); (4) There was a significant difference between SI and cirrhosis with or without esophageal varices (P = 0.031); There is no correlation between cirrhosis and ascites. When SI> 940.42 cm3, patients with cirrhosis are more likely to have esophageal varices. Conclusions SI is of value in predicting high risk esophageal varices. A larger SI value indicates a risk of esophageal variceal bleeding.
