Primary Outcome Measures:
  • to observe a difference in the magnetic activity between the normal and diseased smooth muscle of the stomach and intestines. [ Time Frame: 2010 ]

Secondary Outcome Measures:
  • to specifically study the electrical activity of diabetics with an abnormal gastric emptying. [ Time Frame: 2010 ]
  • Measurement of mesenteric ischemia [ Time Frame: 2010 ]

Enrollment: 78
Study Start Date: June 2000
Study Completion Date: August 10, 2012
Primary Completion Date: August 10, 2012 (Final data collection date for primary outcome measure)
Groups/Cohorts
poor blood flow
Group with partial ischemia to the small intestine
Good blood flow
Group with normal blood flow, given different conditions to effect electrical currents in normal smooth muscle

Detailed Description:
The Squid magnetometer is a non-invasive investigational device that measures the electrical activity in the smooth muscle of the intestines. Volunteers with normal bowel activity, those with gastric problems, and diabetics with gastric problems will be studied under the SQuid to determine normal and abnormal activity. Diabetics with an abnormal gastric emptying study will be asked to participate.
