Assessment of Gastric Emptying Speed in Patients Who Experience Diarrhea Following a Trigger Meal

• Status: Withdrawn
• Trial end date: 2011-01-01
• Target enrollment: 0
• Participant gender: All

Summary

The rapid diarrhea that patients experience who have diarrhea occurring after eating specific foods may be causing a "physiologic gastric dumping syndrome". This means that rather than the food being kept in the stomach for normal digestion, it rapidly goes into the small intestine and diarrhea occurs. This study is designed to measure how fast the food empties from the stomach when a person with this problem consumes a "regular diet", compared to a meal with a "triggering substance". Each participant will swallow a radio frequency capsule that with the different meals that will show how fast the food is traveling through the intestines in the different situations.

2. The patient has provided documented written informed consent/authorization prior to initiation of any study-related procedure.

3. In addition, each patient must report experiencing the onset of urgent defecation within 1 hours of eating a specific trigger which is reproducible at least 90% of the time when consume.

4. The patient must be willing to comply with all of the study protocol.

Exclusion Criteria:

The patient must be willing to allow the Study team to obtain these records for verification of the diagnosis.

2. The patient has nocturnal bowel movements.

3. The patient has been diagnosed with or has a family history of any of the following:

4. The patient has had unexplained anorexia or weight loss of more than 10% of body weight within 12 months of onset of study.

5. Prior GI surgery except of uncomplicated appendectomy and laparoscopic cholecystectomy or history of bowel obstruction or symptoms suggestive of such within the past 2 years.

6. The patient reports daily use of laxatives or stool softeners; use of fiber supplementation is permitted.

7. The patient is currently using pancrealipase. Previous use of pancrealipase in the past is allowed, but patients must be off either of the medication for at least 1 week or until the patient's symptoms of post prandial diarrhea returns before participating in the study.

9. History of gastroparesis or chronic use of reglan.

10. Dysphagia to solid food and pills.

11. Previous gastro-esophageal surgery including vagotomy, fundoplication, gastric bypass or ulcer surgery.

13. Alcohol use within 24 hours prior to capsule ingestion and throughout the entire monitoring period (up to 72 hours).
