Are we missing varices by implementing Baveno-VI recommendation of not screening patients with Compensated Advanced Chronic Liver Disease?
Abstract
Objectives: This study aimed to validate Baveno-VI recommendations for variceal screening in cACLD in our region and proposed our own cutoff values.
Methods: Prospective cross-sectional study was conducted on cACLD patients from August 2020 till April 2021. Patients segregated into Group-A, having Liver stiffness measurement (LSM) of ≥ 20 kPa and platelet of ≤ 150 × 109 cells/L; and Group-B having LSM of < 20 kPa and PLT of > 150 × 109 cells/L. Gastroscopic findings were segregated into three categories, VNT, Varices Not Needing Treatment (VNNT) and No Varix (NV). ROC plots were generated for LSM and Platelet for VNT for sensitivity, specificity, Negative and Positive Predictive Values were calculated.
Results: A total of 134 patients of cACLD were included. Group-A had 72 (53.7%) patients and Group-B had 62 (46.3%) patients. Group-A had 6 (8.3%) NV; 18 (25.0%) VNNT and 48 (66.7%) VNT. Group-B had 26 (41.9%) NV, 24 (38.7%) VNNT and 12 (19.4%) VNT. The sensitivity of 66.7%, specificity of 80.6% and NPV of 67.56% was obtained. Thus 19.4% VNT were missed on following Baveno VI recommendations. ROC in our study suggested cutoff value of 11.5 kPa with sensitivity of 100% and 1-sepcifity pf 78% (AUROC = 0.865; p < .001) of LSM below which screening gastroscopy could be avoided. The positive and negative predicted values for 84.85% and 100% respectively. Cut off value of platelet count for VNNT came out to be ≥ 97.5 × 109 cells/L with AUROC 0.891 (p < .001), having sensitivity of 100 % and 1-specificity of 83.3%.
Conclusions: Substantial number of VNT in cACLD patients are missed by following Baveno-VI recommendations and these needs to be revised on regional basis.
