Abstract

Introduction:Liver fibrosis evaluation is very important for treatment and                            prognosis in patients with chronic liver diseases. The “gold standard” method for liver fibrosis assessment is still considered to be the liver biopsy and histopathology, but in the last years non - invasive methods have increasingly been used, especially   ultrasound based elastographic ones. Objective: to reveal the value of shear wave elastography in Chronic Liver Diseases as a predictor of Gastro-Esophageal Varices with Endoscopic Correlation.  
Material and methods: This is a prospective hospital analytic study enrolling 30patientspresented  by hematemesis and epigastric pain and diagnosed by abdominal US, real time SWE,PV Doppler at Sohag University Hospital using device(Toshiba Aplio 500)and Esophago-gastroduodenoscopy (EGD) during the period from April 2016 to February 2017.
Results:Shear wave was significantly higher among cases compared to controls, there was significant correlation between Shear wave and each of  Portal vein diameter, Peak systolic velocity, CBC findings, serology, US findings, oesophagealvarices, gastric varices, and Child's classification, but there was nonsignificant relation between Shear wave and each of age, sex, residence of the patient.
Conclusion:Shear Wave elastography (SWE) is effective and non invasive tool in prediction  presence of oesophagealvarices in cirrhotic patients.
