Clinical Trials

The aims of this study are to:

1. Study the history of esophageal leiomyomas in patients followed with periodic surveillance with endoscopic ultrasound.

2. Determine baseline characteristics and symptoms of patients diagnosed with esophageal leiomyomas.

3. Determine the transformation rate of malignancy or symptoms (if previously asymptomatic) in patients who undergo interval surveillance EUS examinations for esophageal leiomyomas.

4. Determine risk factors for progression of symptoms or malignancy in patients followed with interval surveillance EUS exams for esophageal leiomyomas.

5. Assess morbidity and mortality in patients followed with interval surveillance EUS examinations for esophageal leiomyomas.

6. Identify malignant sub-epithelial tumors, including leiomyosarcomas, granular cell tumors, and gastrointestinal stromal tumors (GIST) to see ...

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 evaluate the diagnostic performance of Endoscopic Ultrasound (EUS) shear wave elastography in the assessment of liver fibrosis compared to magnetic resonance (MR) elastography.

The primary aim of this study is to determine if there is any evidence of viral shedding within the gastrointestinal or pulmonary system in patients with a prior recent negative nasopharyngeal PCR test. This will be of critical importance to the practice of endoscopy during this pandemic as it will help:  1) determine if a pre-endoscopy testing strategy is adequate to ramp-up access to semi-urgent and eventually elective procedures, while allowing the decreased utilization of limited or costly personal protective equipment (e.g., N95 respirators) while still keeping the GI endoscopy staff safe; and 2) realize the false negative rate of pre-procedural testing, which is vital to inform procedural practice policy and operations.  

The purpose of this study is to compare the incisionless thread carpal tunnel release with the standard mini-open carpal tunnel release (standard of care) in patients with bilateral carpal tunnel syndrome.
