Abstract
ABSTRACT
Background: The development of esophageal varices is one of the major complications of portal hypertension, which is considered a main complication of liver cirrhosis.Variceal bleeding occurs in 20–40% of cirrhotic patients with esophageal varices and The use of endoscopic prophylactic band ligation and non-selective beta blockers can decrease the risk of esophageal bleeding by 50%, so the current guidelines recommend screening all liver cirrhosis patients by endoscopy.
Aim of the Work: Assessment of sensitivity of fib-4, lok score and platelet count / spleen diameter ratio as non-invasive indicator of oesphageal varices in egyptian patients with chronic hepatitis c virus (hcv) infection.
Patients and Methods: This study will include 100 egyptian patients selected from internal medicine and hepatology outpatient clinics and inpatient wards at matria teaching hospital.
Results: Plt count/spleen diameter ratio, plt count and spleen diameter demonstrated a high statistically significant correlation with the presence and grade of esophageal varices. as according to sensitivity and specificity test the most accurate screening test for diagnosis of esophageal varicose is PLT/SD ratio as AUC (87.4%), also it is a good negative test as specificity (86.7%) with cutoff value (1026.7), but for suspect a case most sensitive test is PLT count as sensitivity (93.3%) with cutoff value (120.5). these tests followed by spleen diameter with accuracy (78.2%), and the least test is right lobe/ albumin ratio which cannot depend on it in diagnosis of esophageal varices as its accuracy is (52.2%),sensitivity 66.7% and specificity 48.3%.
Conclusion: The use of plt count/spleen diameter ratio, plt count and spleen diameter, especially the platelet count/spleen diameter ratio, can help physicians as noninvasive predictors of esophageal varices to restrict the use of endoscopic screening only to patients presenting a high probability of esophageal varices. This is especially useful in clinical settings where resources are limited and endoscopic facilities are not present in all areas.While rt liver lobe/albumin ratio can not be used as a non invasive predictor of esophageal varices.
