Objective: The aim of our study was to evaluate the indocyanine green (ICG) retention test as a noninvasive marker of esophageal varices(EV).
Result: A total of 144 patients (88 M/56 F, 51.7 Ā± 11.06 years) were enrolled. The ICG retention at 15 min(ICG-r15), PVD, TBIL, Cholinesterase(CHE), AST to ALT ratio(ARR), APRI, splenic area, Lok index, Park index and liver stiffness measurement in the absent or small EV group were lower than those in the medium or large EV group, while the ICG disappearance rate(ICG-K), Effective hepatic blood flow(EHBF), ALB, PLT, and Platelet to Spleen Diameter Ratio(PSDR) were higher, and the differences were significant (P < 0.05). ICG-r15, splenic area, APRI and PLT were independent predictors for medium or large esophageal varices (OR = 1.115, 1.025, 0.281, and 0.987, respectively, P < 0.05). The predictive value of ICG-r15 for medium or large varices was 17.95%, the specificity was 0.849, and the sensitivity was 0.662, the AUROC was 0.815. The cut-off value of PLT for M/L EV was 113.5, and the specificity and sensitivity were 0.616 and 0.887, the AUROC was 0.759. The AUROC of ICG-r15 combined with PLT was 0.866, which was more superior than others.
Conclusion: Although we are far from the replacement of endoscopy, ICG-r15 combined with PLT seems to be able to identify patients with medium or large EV in patients with compensated liver cirrhosis.
