  Purpose

The purpose of this study is to determine whether ultrasound-based assessment of intestinal stiffness in patients with Crohn's disease predicts the effectiveness of medical therapy or the need for surgical resection.

Further study details as provided by University of Michigan:

Primary Outcome Measures:
  • Change in CDAI Score Over 90 days from Hospital Admission [ Time Frame: CDAI Score measured over 90 days ] [ Designated as safety issue: No ]

    CDAI score will be assessed at 3 time points:

    Hospital Admission Hospital Discharge 90-day follow-up


  • Shear Wave Velocity [ Time Frame: Day 0,3,5,7 of Hospitalization ] [ Designated as safety issue: No ]
    Ultrasound shear wave velocity measurements in bowel wall


Secondary Outcome Measures:
  • Need for Re-hospitalization or Surgery within 90 days of discharge [ Time Frame: 90 days post discharge ] [ Designated as safety issue: No ]
    Telephone follow up with subjects 90 days following index hospitalization to assess need for re-hospitalization or surgery


Estimated Enrollment: 80
Study Start Date: September 2012
Estimated Study Completion Date: January 2015
Estimated Primary Completion Date: July 2014 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Crohn's Inpatients
Crohn's Inpatients, with clinical small bowel obstruction All undergo ultrasound stiffness imaging (USI) of distal affected ileum.
Procedure: Ultrasound stiffness imaging
Subjects will undergo transabdominal ultrasound of the distal intestine. Distal intestine motion capture will be used for off-line stiffness assessment by two-dimensional speckle tracking. In addition, shear wave imaging will be used for real-time stiffness assessment.
Crohn's Outpatients
Crohn's Outpatients, starting anti-TNF therapy All undergo ultrasound stiffness imaging (USI) at week 0, 6, 14
Procedure: Ultrasound stiffness imaging
Subjects will undergo transabdominal ultrasound of the distal intestine. Distal intestine motion capture will be used for off-line stiffness assessment by two-dimensional speckle tracking. In addition, shear wave imaging will be used for real-time stiffness assessment.
