Gastroparesis Clinical Trial
Official title:
Pyloric Sphincter Abnormalities in Patients With Gastroparesis Symptoms
The overall objective of this study is to determine if there are pyloric sphincter abnormalities in patients with gastroparesis symptoms and determine how prevalent these abnormalities are using tests to assess the pyloric sphincter - endoluminal functional luminal imaging probe (Endoflip™), water load satiety testing (WLST), and high-resolution cutaneous electrogastrography (HR-EGG) using Gastric Alimetry™ System.
Study Description: This is a multi-center, prospective, observational study to assess pyloric sphincter abnormalities in patients with symptoms of gastroparesis (both delayed and normal gastric emptying) and control participants without symptoms of gastroparesis using the commercially available, FDA approved endoluminal functional luminal imaging probe (Endoflip™) catheter, which measures diameter, cross-sectional area, pressure, compliance, and distensibility of gastrointestinal sphincter muscles. This study will assess lower esophageal and pyloric sphincter diameter, CSA, pressure, distensibility, and compliance in patients with symptoms of gastroparesis and delayed gastric emptying, patients with symptoms of gastroparesis but with normal gastric emptying, and normal control participants. The protocol will also include a water load satiety test and use Gastric Alimetry™ System that assesses gastric myoelectrical activity in symptomatic participants but not control participants. ;
