Abstract:
Objective To investigate the risk factors for rebleeding after emergency esophageal variceal ligation (EVL) in patients with liver cirrhosis. Methods A retrospective analysis was performed for the clinical and laboratory data of 290 patients with liver cirrhosis who underwent emergency EVL in The Fifth Medical Center of Chinese PLA General Hospital from January 2016 to December 2019, and according to the presence or absence of rebleeding within 1-year follow-up, they were divided into rebleeding group and non-rebleeding group. The t -test was used for comparison of normally distributed continuous data between two groups, and the Wilcoxon rank sum test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups. A multivariate logistic regression analysis was performed with the statistically significant factors as independent variables to screen out the independent risk factors for rebleeding after emergency EVL, and the receiver operating characteristic (ROC) curve was plotted to obtain the indices for predicting the probability of rebleeding and establish a predictive model. Results The univariate analysis showed that there were significant differences between the two groups in platelet count ( t =-1.888, P =0.047), Child-Pugh score ( χ 2 =5.975, P =0.049), albumin level ( t =-2.229, P =0.029), and splenic vein diameter ( t =3.808, P =0.001). The multivariate logistic regression analysis showed that Child-Pugh score (odds ratio [ OR ]=0.280, 95% confidence interval [ CI ]: 0.108-0.729, P =0.009), splenic vein diameter ( OR =1.549, 95% CI : 1.197-2.005, P =0.001) and albumin level ( OR =0.832, 95% CI : 0.729-0.949, P =0.006) were independent influencing factors for rebleeding after EVL. The predictive model based on these three factors had an area under the ROC curve of 0.796, with a sensitivity of 83.7% and a specificity of 74.5% at the cut-off value of -0.086. Conclusion Child-Pugh score, albumin level, and splenic vein diameter are independent risk factors for rebleeding after emergency EVL, and the combination of the three indices has the highest sensitivity and specificity in predicting rebleeding.
