  • A Multicenter, Prospective, Randomized Study on Endosonographic Evaluation of Pancreatic Cystic Lesions Using 22 G, 19 G, and Flexible 19 G Fine Needle Aspiration Scottsdale/Phoenix, Ariz., Jacksonville, Fla.

    To document impact of EUS-FNA needle size and flexibility on effectiveness of pancreatic cystic lesions (PCL) aspiration, on ability to obtain sufficient material for standard diagnostic testing, and on diagnostic accuracy of EUS-FNA aspirate for differentiation of mucinous (pre-malignant) and non-mucinous cysts.

  • A Randomized, Double-Blind, Comparative, Effectiveness and Safety Study of SIC 8000 in Subjects Undergoing Endoscopic Mucosal Resection (EMR) of Colonic Lesions Equal to or Larger than 2 cm Jacksonville, Fla.

    The purpose of this study is to assess the effectiveness of SIC 8000 injected into the submucosa under polyps, adenomas, early-stage cancers or other gastrointestinal mucosal lesions to provide a lift to them prior to grasping and cutting with a snare during endoscopic removal procedures.

  • Contrast-Enhanced Harmonic Endoscopic Ultrasound Imaging – A Patient Registry Jacksonville, Fla.

    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.

  • Pilot-Feasibility Trial of EUS Guided Pancreas Fine Needle Core Biopsy for Whole Exome Sequencing and Genomic Profiling Jacksonville, Fla.

    This is a clinical trial to compare two needles used in biopsy techniques to acquire tissue from pancreatic cancer. The hypothesis is that the tissue yield, as measured by tumor DNA and cellular material is superior for Flexible Needle Biopsy (FNB) compared with conventional Fine Needle Aspiration (FNA). Specifically, FNB will increase the proportion of cases in which sufficient DNA is obtained to allow genomic profiling and whole exome sequencing.

  • Prospective Evaluation of the Clinical Utility of Budesonide for the Prevention of Esophageal Strictures after Endotherapy Jacksonville, Fla.

    Surgery has been historically the mainstay treatment for advanced pre-malignant lesions and early esophageal cancers. However, esophagectomy is associated with significant morbidity and mortality. With the advance of therapeutic endoscopy, there has been a growing interest and application of endoscopic resection and mucosal ablative techniques for the treatment of these diseases. Esophageal stricture(ES) formation has become an increasingly recognized complication of extensive endoscopic mucosal ablation and/or resection. The resultant symptomatic stricture development can significantly impair a patient's quality of life. Endoscopic therapy of esophageal strictures with balloon dilation and/or local steroid injection is invasive, costly, and associated with the potential risk of perforation. Recently, oral corticosteroids have been introduced for the prevention of esophageal stricture after endoscopic submucosal dissection.

    Budesonide is a synthetic steroid with topical anti-inflammatory properties and high first-pass metabolism; thus, potentially less systemic absorption and side effects.

    Hypothesis: Oral budesonide prevents esophageal stricture formation in patients who underwent radical endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) for advanced premalignant esophageal lesions or superficial esophageal cancers.
