Clinical Trials

The purpose of this study is to find the long-term outcomes of patients with hyper-contraction of the esophagus and outflow obstruction of the gastroesophageal junction by reviewing high resolution manometric tracings.

The purpose of this study is to evaluate and compare esophageal high resolution impedance manometry (HRIM)  with direct mucosal impedance  catheter diagnostic measurements in patients with gastroesophageal reflux disorder.

The purpose of this study is to determine the prevalence of esophageal dysmotility among patients following bariatric surgery.
 

The purpose of this study is to identify a predictive model for worsening of preexisting gastroesophageal reflux disease (GERD) or development of de novo GERD after laparoscopic sleeve gastrectomy (LSG) by using EndoFLIP, upper endoscopy and esophageal manometry to assess patients preoperatively in a discovery cohort.  This prospective predictive model will then identify sensitivity, specificity, positive and negative predictive values for prediction of worsening or de novo GERD.

This study aims to assess the utility of pharyngeal manometry measures as a novel approach in quantifying  internal lymphedema and compare success rates in reducing internal lymphedema using manual lymphatic drainage (MLD) versus use of a pneumatic compression device (PCD). It also aims to assess efficacy of PCD and MLD and assess compliance of treatment in both groups. Lastly, it aims to identify voice and swallowing changes in both groups.
