Purpose
Endoscopic Ultrasound involves the placement of a small flexible camera through the mouth and into the stomach to image various parts of the body. A small piece of tissue called a biopsy, of your liver nay be obtained by this method. the tissue (biopsy) would be obtained by inserting a small needle through the lining of the stomach into the liver. Consideration for this biopsy is because there may be extra fat stored within the liver. In some people who drink too much alcohol, extra fat may be stored in the liver, however, in some people who don't drink too much alcohol, this may also occur and is called :non-alcoholic fatty liver disease or NAFLD. Over time, this extra fat may lead to liver irritation and scar tissue called cirrhosis. If NAFLD is detected early enough, then treatment with medications, losing weight, or dietary changes may help avoid cirrhosis. the purpose of this study is to learn about whether doctors can obtain the biopsy from the liver by a new method. The biopsy of the liver allows the doctors to look for any signs of scar tissue or inflammation from any cause.

Primary Outcome Measures:
- To evaluate the utility, diagnostic yield and complications of EUS-TCB for the histologic diagnosis of suspected NAFLD. This is a "proof of concept" pilot study. [ Time Frame: 24 months ] [ Designated as safety issue: Yes ]
Secondary Outcome Measures:
- Transgastric EUS-TCB may prove to be a safe alternative to percutaneous and transjugular liver biopsy methods in obtaining liver biopsy samples [ Time Frame: 24 months ] [ Designated as safety issue: Yes ]

Transgastric EUS-TCB may prove to be a safe alternative to percutaneous and transjugular liver biopsy methods in obtaining liver biopsy samples.
|
Device: EUS Tru-cut biopsy
Transgastric EUS-TCB may prove to be a safe alternative to percutaneous and transjugular liver biopsy methods in obtaining liver biopsy samples. This technique may be particularly helpful to obtain liver biopsies in patients with morbid obesity or patients in whom there is no obtainable view to obtain a percutaneous biopsy.

Criteria
Inclusion Criteria:
- Patients between the ages of 18 and 70 years old referred to Indiana University Hospital for outpatient upper EUS for clinical purposes (e.g., pancreatic disease).
- Increased hepatic enzymes (AST or ALT) above the upper limit of normal within the past 3 months. These values at University Hospital are ALT>45 U/L and AST> 41 U/L but may vary among laboratories at different institutions.
- Evidence of fatty liver (as detected by an increase in echogenicity or brightness of the liver) by EUS exam.
- Liver biopsy for suspected NAFLD is clinically indicated as determined by Dr Naga Chalasani, one of our staff hepatologists who is an expert in NAFLD.
Exclusion Criteria:
- Inpatient status.
- Normal liver enzyme tests (AST, ALT).
- Previous or current alcohol abuse (≥3 drinks/day for men; ≥2 drinks/day for women)
- Planned liver biopsy within 30 days for known or suspected liver disease.
- Suspected metastatic lesion in the liver by any previous imaging study or discovered during EUS exam.
- EUS-FNA of the liver is required for another reason (i.e. suspected metastatic lesion)
- Newly diagnosed, currently treated or suspected malignancy. (In this case, the diagnosis of NAFLD would not likely impact patient care or survival). Patients with a previously diagnosed malignancy that is in remission will be considered eligible.
- Previously diagnosed NAFLD including steatosis or NASH (in this situation, another biopsy is not beneficial to the patient).
- Chronic liver disease including Hepatitis B, Hepatitis C, Wilson's disease, alpha-1-antitrypsin disease, autoimmune hepatitis.
- Known or suspected cirrhosis.
- Esophageal or gastric varices by previous imaging or discovered during EUS.
- Previous liver surgery including resection or transplant.
- Thrombocytopenia (platelets <150,000)
- Anemia (hemoglobin <10 gm/dL).
- Coagulopathy (INR>1.2 or aPTT > 35 secs).
- Use of coumadin or other anticoagulants.
- Use of aspirin or nonsteroidal antinflammatory product within 7 days of EUS.
- Total bilirubin >2.0 mg/dL and dilated bile duct on previous imaging study.
- Inability to provide informed consent.
- Pregnancy or suspected pregnancy.
