The purpose of this study is to look at the electrical activity present in healthy and diseased smooth muscle of the intestines; and develop both mathematical and computer models.

Condition Phase
Phase 1

Study Type: Observational
Study Design: Observational Model: Case Control
Time Perspective: Cross-Sectional
Official Title: Realistic Models of Gastrointestinal Bioelectromagnetism

Further study details as provided by Vanderbilt University:

Primary Outcome Measures:
  • To observe a difference in the electrical activity between normal and diseased smooth muscle of the intestines. [ Time Frame: 2011 ]

Secondary Outcome Measures:
  • To create both mathematical and computer models of the electrical activity of the intestines. [ Time Frame: 2011 ]

Estimated Enrollment: 60
Study Start Date: February 2004
Estimated Study Completion Date: July 2011
Good blood flow
Group without ischemia to the small intestine
Poor blood flow
Groups that have partial ischemia to their small intestine

Detailed Description:
The Superconducting QUantum Interference Device (SQUID)is a large cylinder machine located in a large shielded room that measures magnetic activity of the intestines. Subjects will be asked to lie underneath and get recordings of the electrical activity of their intestines. They will also be asked to have a CT scan done. From these two procedures, the mathematical and computer models will be developed to determine the difference between normal bowels and those that do not have adequate blood supply.

Accepts Healthy Volunteers:   Yes
Sampling Method:   Non-Probability Sample
