Healthy Clinical Trial
Official title:
Gastro-intestinal Biopotential Recorder by Means of Surface ELEctrodes
The goal of this clinical trial is to compare the gastro-intestinal biopotentials recorded with a homemade device using surface electrodes placed on the abdomen in healthy volunteers, Crohn's disease patients without fibrosis, Crohn's disease patients with fibrosis and in functional gastrointestinal disorders (FGID) patients. The main question it aims to answer is: • Is there any differences in the gastro-intestinal biopotentials between the different populations under study? It aims to answer two secondary questions: - Are the gastro-intestinal biopotentials comparable to the Harvey-Bradshaw Index, MRI and biological data for patients with Crohn's disease? - Are the gastro-intestinal biopotentials comparable to Rome IV criteria for functional gastrointestinal disorders patients? Participants will undertake two recordings made with the device. The first one will last 1 hour and 30 minutes and will occurs while the participants are fasting. Then, the participants will eat a standardized meal. Finally, the second recording will take place after the meal ingestion and will last 1 hour and 30 minutes while the participants are in postprandial state.
Diseases and disorders of the digestive tract affect a large proportion of the world's population. These disorders or diseases degrade patients' quality of life and are costly for healthcare systems. Today, it is difficult to categorize, monitor and/or prognosticate their evolution due to their unknown etiologies, the long duration of the digestion processes and unsuitable (invasive, complex or costly) examinations. However, electrophysiology holds great promise for the study of these diseases. Indeed, the organs of the digestive tract are made up of longitudinal and circular muscles which contract rhythmically and synchronously to advance the food bolus during digestion, or to cleanse the digestive tract once digestion is complete. No study has yet demonstrated the feasibility and value of measuring these bio-potentials for Functional Gastro Intestinal Disorders and Inflammatory Bowel Diseases. That's why a homemade gastro-intestinal biopotentials recorder was developped. The recorder uses surface electrodes placed on the abdomen to record this biopotentials. The investigators hypothesize that surface gastro-intestinal biopotentials differ between a population of healthy volunteers, Crohn's disease patients and FGID patients. ;
