Evaluation of Gastrointestinal Motility With SmartPill

This study has been completed.

The purpose of this study is to evaluate the clinical usefulness of a capsule (SmartPill~) measuring pH, pressure and temperature from within the entire GI tract to determine gastric emptying time, combined small and large bowel transit time and total transit time. In addition, the Capsule will characterize pressure patterns and provide motility indices for the antrum and duodenum. It is believed that the condition of your digestive system can have a large impact on your overall physical health. Therefore,the investigators would like to assess whether using the pill device helps to determine any functional problems in patients in the ICU. The investigators are studying ICU patients because any change in their condition can have a large impact on their recovery.

Condition Intervention
Gastrointestinal Motility Device: SmartPill

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Clinical Evaluation of SmartPill Capsule for Investigation of Total Intestinal Transit Time and Intestinal Pathology in Critically Ill Patients

Further study details as provided by Stefan Raugh, University of Louisville:

Primary Outcome Measures:
  • Transit time [ Time Frame: 5 days ]
    The subjects were followed from the time of placement of the capsule in the stomach until the capsule was viewed in the stool or abdominal X-rays revealed it had passed from the body

Enrollment: 8
Study Start Date: November 2007
Study Completion Date: January 2009
Primary Completion Date: May 2008 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Critically ill ICU patients
ICU patients with brain injuries who will be receiving a feeding tube.
Device: SmartPill
Qualifying patients were assigned to the study within four days of hospital admission. They all received a gastro-duodenal tube and capsule. The motility capsule (SmartPill®) was placed into the capsule delivery device (AdvanCE™, US Endoscopy) and advanced blindly into the stomach and released
