Influencing factors and efficacy of endoscopic tissue adhesives injection in preventing esophageal gastric varices bleeding / 中华消化杂志

ABSTRACT

Objective To explore the prognosis of endoscopic tissue adhesives injection in treating liver cirrhosis patients with esophageal gastric varices (GOV),and to evaluate the effects of various factors on bleeding after treatment.Methods A total of 157 liver cirrhosis patients with GOV treated by endoscopic tissue adhesives injection with or without ligation therapy were retrospectively analyzed.The basic information,liver function and blood biochemical values of patients at enrollment were investigated.The analysis of bleeding after treatment was conducted by Kaplan-Meier.The survival curves comparison was conducted by Log-rank test.Logistic regression model was used for multivariate analysis.The prognosis predictors were evaluated by receiver operating characteristics (ROC) curves and the area under the curve (AUC).Results Rebleeding happened in 26 of 157 patients.The median rebleeding time was 3.4 months.The results of univariate analysis indicated that there were statistical differences in FIB4 scores (Z=-1.282,P=0.100) and the inner diameter of the right portal vein (Z=-1.812,P=0.035) between bleeding group and no bleeding group.The results of multivariate analysis showed that the inner diameter of the right portal vein was independent prognostic factor of rebleeding (OR =1.733,95％ CI1.045 to 2.874,P =0.033).Optimal diagnostic threshold was 8.5 mm (AUC=0.724,95 ％CI0.537 to 0.910),sensitivity and specificity was 77.8％ and 66.6％ respectively.Conclusions The inner diameter of the right portal vein was one of the important factors that affected the efficacy of tissue adhesives injection in preventing bleeding and the prognosis.FIB4 score had certain reference value in predicting recurrence or bleeding after treatment.
