Description of intervention(s) / exposure
Endoscopic ultrasound (EUS)-The patients refered to EUS examination for regular etiologies such as pancreatic cysts, subepithelial lesions, investigation of common bile duct Stones etc will be examined for hepatic parenchymal stiffness using the software for elastography measurement that is already available with the device. This procedure will add only 2-3 minutes to the EUS examination. A seperate and dedicated EUS session will not be planned for the whole patient groups. Those having accompanying Chronic hepatitis B or C or nonalcoholic hepatitis will be evaluated as the study group.

Comparator / control treatment
Patients who are evaluated by endoscopic ultrasound for other causes such as subepithelial lesions, pancreatic cysts, etiology of chronic pancreatitis will also be evaluated for the hepatic elastography during the same session.
Control group
Active

Outcomes
Primary outcome [1] 301054 0
Relationship between age of patient and the liver elastography results. Age will be assessed by the birth certificate records and the liver elastography will be measured by endoscopic ultrasound using a special software.
Timepoint [1] 301054 0
At completion of Endoscopic ultrasound
Primary outcome [2] 301278 0
Relationship between obesity and the liver elastography results. Obesity will be assessed by the height, weight and waist circumference measures obtained by the attending physician and the liver elastography will be measured by endoscopic ultrasound using a special software.
Timepoint [2] 301278 0
at completion of Endoscopic ultrasound
Primary outcome [3] 301279 0
Relationship between history of diabetes and the liver elastography results. History of diabetes will be assessed by the self report of the patient and the liver elastography will be measured by endoscopic ultrasound using a special software.
Timepoint [3] 301279 0
at completion of Endoscopic ultrasound
Secondary outcome [1] 331600 0
Relationship between the liver elastography measures obtained by endoscopic ultrasound (EUS) and the histologic liver fibrosis amount in chronic hepatitis patients who have undergone a liver biopsy within the last one year of the EUS procedure. For this outcome, we will not require a liver biopsy but only review the records of the patients.
Timepoint [1] 331600 0
At completion of Endoscopic ultrasound

Statistical methods / analysis
Liver elastography measures will be numeric values. We will compare those values between study and control groups using student Ttest. For the study group, those patients having a recent liver bipsy will be further analysed using the liver inflammation and fibrosis categories. For this purpose we will usei spearman's correlatiion analysis and chi-square tests.

Summary
Brief summary
Endoscopic ultrasound (EUS) is a good tool for real-time visualization of the left liver lobe and it has a software to measure the liver elastography which shows the stiffness of the liver. The comparison of EUS-liver elastography and liver biopsy parameters of inflammation and fibrosis is not known. Although EUS is an invasive endoscopic procedure, it has unique beneficial role for the evaluation of subepithelial masses of gastrointestinal tractus such as esophageal varices, common bile duct anomalies such as stones, pancreatic cysts, mediastinal masses....etc. During EUS examination for any indication, the operator can easyly evaluate the liver and can add the liver stiffness findings to the report. This study aims to prospectively evaluate the value of EUS-liver elastographic measurements in patients with chronic hepatitis B, C and nonalcoholic fatty liver disease who were referred to EUS for other indications. The patients who have biopsies in the last 2 years of the EUS-examination will be compared by their EUS- elastography findings and biopsy findings. There will be a control group who have no known positivity for viral hepatitis serology and no liver disease.
