Abstract:
Objective: To explore the value of shear wave elastic imaging (SWE) in diagnosis of esophageal varices (EV), low-risk EV and high-risk EV, as well as predicting EV rupture hemorrhage. Methods Totally 103 patients with clinically diagnosed liver cirrhosis were enrolled. All patients were examined with ultrasonography, endoscopy and laboratory examination. The diagnostic value of sex, age, body mass index (BMI), Child-Pugh classification, liver stiffness (LS)×spleen diameter and platelet count ratio index (LSPS), aspartate aminotransferase and platelet count ratio index (APRI), LS, spleen stiffness (SS) to with or without EV, low risk EV and high risk EV, as well as of EV rupture hemorrhage were analyzed, and correlation analysis was then performed. Results Child-Pugh classification, LSPS, APRI, LS and SS had statistical difference in patients with or without EV (all P<0.05). LS and SS were independent factors in diagnosis of EV. AUC of LSPS, APRI, LS and SS in diagnosing EV was 0.84, 0.79, 0.83 and 0.89, respectively. Child-Pugh classification, LS and SS had statistical differences between low-risk EV and high-risk EV (all P<0.05). There was statistically significant difference of SS in identification of EV with or without rupture hemorrhage (P<0.01). SS was an independent risk factor for predicting high-risk EV and rupture hemorrhage. The correlation between with or without EV and Child-Pugh classification was weak (r=0.35, P<0.05), and the correlation with LSPS, APRI and LS were moderate (r=0.52, 0.45, 0.51, P<0.05), while with SS was strong (r=0.61, P<0.05). Conclusion: SWE is of high diagnostic value for EV, low-risk EV and high-risk EV as well as EV rupture hemorrhage, and can be used as a non-invasive method for predicting EV. The diagnostic value of SS for EV is higher than LS.
