Biomagnetic Signals of Intestinal Ischemia II - Full Text View

Purpose

The lack of blood flow to the small intestine causes mesenteric ischemia. Using a Superconducting QUantum Interference Device (SQUID) which measures the magnetic field of the small intestine, we are hoping to identify abnormalities without surgical intervention.

Further study details as provided by Vanderbilt University:

Primary Outcome Measures:

to observe a difference in the magnetic activity between the normal and diseased smooth muscle of the small intestine [ Time Frame: 2010 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Create mathematical and computer models of electrical activity of smooth muscle [ Time Frame: 2010 ] [ Designated as safety issue: No ]

Biospecimen Retention: None Retained

Biospecimen Description:

Estimated Enrollment:	60
Study Start Date:	January 2000
Estimated Study Completion Date:	June 2010

Groups/Cohorts

A

Group with normal blood flow

B

Group with abnormal blood flow

Detailed Description:

The electrical activity of the small intestine may contain important information that will help us diagnose gastrointestinal diseases. The major impediment to reducing mortality of mesenteric ischemia is the lack of a noninvasive diagnostic test that identifies the syndrome before extensive necrosis occurs. Mesenteric ischemia is caused by the lack of blood flow to the intestine. The Superconducting QUantum Interference Device (SQUID) measures the magnetic field of the intestinal smooth muscle. By comparing normal smooth muscle and that of patients with mesenteric ischemia, we hope to identify abnormal disease states without surgery.
