Accuracy of noninvasive tests in the prediction of portal hypertensive gastropathy in Egyptian patients with cirrhosis

Background and Aim Liver cirrhosis (LC) is commonly associated with portal hypertensive gastropathy (PHG), and it causes gastrointestinal (GI) bleeding. Esophagogastroduodenoscopy (EGD) is the gold standard in diagnosing PHG. Besides its invasiveness, the disadvantages of EGD include psychological and financial problems. We aimed to evaluate the diagnostic accuracy of different noninvasive screening tools in predicting PHG. Methods This cross-sectional study was conducted on 100 patients with LC who were divided into two groups based on EGD: group (A), 50 patients with LC with PHG, and group (B), 50 patients with LC without PHG. All patients were subjected to history taking, full clinical examination, laboratory investigations, abdominal-pelvic ultrasonography, and EGD. Results To predict PHG, the respective sensitivity and specificity of portal vein diameter (>10.5 mm) were 86 and 67%, of gallbladder wall thickness (GBWT) (>3.5 mm) were 64 and 68%, of platelets/GBWT (<40) were 68 and 78%, of aspartate aminotransferase (AST)/platelet ratio index (APRI) score (>1.1) were 60 and 66%, of platelet/spleen diameter (<1290) were 88 and 72%, of right liver lobe diameter/albumin ratio (>4) were 74 and 80%, and of AST/alanine aminotransferase (ALT) ratio (>1.1) were 50 and 58% (P = 0.353). Conclusion Portal vein diameter, platelet/spleen diameter, and right liver lobe diameter/albumin ratio were independently associated with PHG and were good predictors of the PHG, whereas AST/ALT ratio and King score are poor predictors.
