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 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 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.
