Background: Gastroesophageal varices due to portal hypertension in patients with liver cirrhosis is an important cause of morbidity and mortality. Gold standard investigation for varices is esophagogastroduodenoscopy and patients are advised to undergo regular follow up based on the risk stratification. But the invasive nature, risk of procedure-related complication and lack of accessibility and affordability makes it important to identify simpler methods to screen patients. Platelet count/spleen diameter (PSD) ratio has been validated as a marker for oesophageal varices (OV) in multiple studies but with varying results. The present study was conducted to evaluate the accuracy of PSD ratio in OV.Methods: A cross-sectional study was conducted in patients diagnosed with liver cirrhosis. Clinical examination, relevant laboratory investigations, abdominal ultrasound and endoscopy were performed and data were recorded. PSD was calculated. Receiver-operator characteristics curves were plotted to determine cut-off values. Sensitivity, specificity, positive and negative predictive values were calculated.Results: Total 100 patients were included in this study, out of which 25% of patients did not have varices on endoscopy. The mean PSD was for patients without varices 1242.82 (253.45) and 883.51 (582.38467) for patients with OV. The area-under-curve was 0.823, 95% CI=0.734-0.912, p value=0.000001. The cut-off value for PSD was calculated from the ROC analysis was 1077. The sensitivity, specificity, positive and negative predictive values were 76%, 88%, 95% and 55% respectively.Conclusions: PSD ratio is not an efficient parameter for detection of varices in patients with liver cirrhosis. The current evidence does not support its role as a screening test for identification of patients with OV.
