• Motility disorders of the esophagus, stomach, small intestine and colon

• Clinical disorders including:

  Esophageal:  gastroesophageal reflux disease, achalasia, non-cardiac chest pain, esophageal spasm

  Gastric:  gastroparesis, functional dyspepsia

  Small bowel:  irritable bowel syndrome, intestinal pseudo-obstruction

  Colorectal:  constipation, fecal incontinence

• Use of multichannel electrogastrography to assess gastric myoelectrical activity to detect gastric motor function in patients with dyspeptic symptoms
• Development of a noninvasive test to measure simultaneously both gastric emptying and gastric volume after ingestion of a solid meal under physiologic conditions.  This will be useful to define the pathophysiologic factors which cause symptoms in patients with functional dyspepsia and be useful to test the effects of new pharmaceutical agents.
• Gastric motility
• Breath tests for gastric emptying
• Electrogastrography (EGG)
• New pharmaceutical treatments for gastroparesis and functional dyspepsia
• Small bowel motility recordings
• Esophageal pH
• Motility recordings
