Open for enrollment
The purpose of this study is to evaluate the usefulness of combining a core liver biopsy guided by endoscopic ultrasound and stomach balloon placement by endoscope for the diagnosis and treatment of fatty liver disease and obesity.
Closed for enrollment
The aims of this study are to:
Study the history of esophageal leiomyomas in patients followed with periodic surveillance with endoscopic ultrasound.
Determine baseline characteristics and symptoms of patients diagnosed with esophageal leiomyomas.
Determine the transformation rate of malignancy or symptoms (if previously asymptomatic) in patients who undergo interval surveillance EUS examinations for esophageal leiomyomas.
Determine risk factors for progression of symptoms or malignancy in patients followed with interval surveillance EUS exams for esophageal leiomyomas.
Assess morbidity and mortality in patients followed with interval surveillance EUS examinations for esophageal leiomyomas.
Identify malignant sub-epithelial tumors, including leiomyosarcomas, granular cell tumors, and gastrointestinal stromal tumors (GIST) to see if there was a history of benign neoplasm preceding their diagnosis.
Evaluate symptom progression in follow up by contacting patient to complete a validated, brief questionnaire (BEDQ: Brief Esopageal Dysphagia Questionnaire).
The purpose of this study is to assess the risk for cancer spread caused by the leaking of tumor particles into the blood from the biopsy procedure endoscopic ultrasound guided fine needle aspiration.
The purpose of this study is to describe the findings and outcomes of patient undergoing contrast-enhanced harmonic endoscopic ultrasound (CE-EUS) imaging. A registry will be created to monitor for possible procedure adverse events and to perform descriptive statistics for the patients who undergo this procedure.

The purpose of this study is to determine if microbiome DNA can be detected in the juice from the upper GI tract and that of the clinical residual specimens from patients who have or will experience an endoscopic ultrasound with sampling as part of their clinical care.
The goal of this study is to establish a completely quantitative and objective criterion for differentiating malignant from benign lymph nodes using Image J to interpret endoscopic elastography hue histograms.
