Summary
This study establishes normative values for gastric motility using the 3D-Transit system, providing key data for gastrointestinal transit and gastric emptying assessments in healthy adults.
Area of Science:
- Gastroenterology
- Medical Devices
- Physiology
Background:
- The Motilis 3D-Transit system offers ambulatory assessment of gastrointestinal transit patterns.
- It presents an alternative method for studying gastric motility.
Purpose of the Study:
- To establish normative values for gastric motility using the 3D-Transit system.
- To define reference ranges for gastric emptying and contraction parameters.
Main Methods:
- 132 healthy volunteers ingested the 3D-Transit capsule for gastrointestinal transit time assessment.
- Newly developed software analyzed recordings for gastric emptying, contraction frequency, and movement.
- 46 subjects underwent testing on consecutive days to assess variability.
Main Results:
- Median gastric emptying time was 2.7 hours; 89% of subjects emptied within 6 hours.
- Median gastric contraction frequency was 3.1/min, higher in women and increasing with age.
- Gastric motility amplitudes varied with gender, BMI, age, and meal caloric content.
Conclusions:
- Normative values for gastric motility using the 3D-Transit system have been successfully established.
- This provides a basis for clinical interpretation of gastric motility assessments.

Gastric motility is the coordinated contraction and relaxation of stomach muscles that convert ingested food into chyme, a semi-liquid substance ready for further digestion in the intestines. The process begins with the vagus nerve inducing the relaxation of the smooth muscles in the fundus and body of the stomach, allowing these regions to expand and accommodate up to approximately 1.5 liters of food and liquid.

This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

01:20Gastrointestinal Motility Disorders
984
Gastrointestinal or GI motility disorders are characterized by irregular gastrointestinal tract movements, disrupting food transit from the mouth to the anus. They are caused by damage or dysfunction in gut muscles or nerves. These disorders can cause symptoms such as severe constipation, diarrhea, abdominal pain, and swallowing difficulties. Disorders can affect any segment of the GI tract and range widely in severity, from common conditions like GERD to life-threatening conditions like...

01:16Gastric Emptying
3.0K
Gastric emptying occurs when the stomach gradually releases chyme into the duodenum. When the stomach is distended, it triggers the release of gastrin, a hormone that promotes gastric acid secretion to aid in digestion. Additionally, stomach distension contributes to peristaltic waves that propel gastric contents toward the pyloric region. The gastroenteric reflex, on the other hand, primarily stimulates peristalsis in the intestines, facilitating the movement of contents further along the...

01:23Drugs Affecting GI Tract Motility: Serotonin Receptor Agonists
812
Serotonin, a crucial neurotransmitter synthesized by enterochromaffin cells, plays a cardinal role in regulating gastrointestinal (GI) motility. With over 90% of the body's total serotonin in the GI tract, its influence on digestive processes is profound. Serotonin is swiftly released upon various stimuli, such as food boluses or certain drugs, triggering intrinsic sensory neurons in the myenteric plexus and extrinsic vagal and spinal sensory neurons. This leads to the activation of the...

01:26Gastric Phase of Digestion
2.9K
The gastric phase of digestion begins as soon as food enters the stomach. The incoming food bolus triggers neural and hormonal mechanisms, which last approximately 3 to 4 hours. During this phase, the stomach undergoes significant changes to prepare the food for further digestion and absorption.
When food enters the stomach, it stretches the stomach walls and activates stretch receptors. This triggers local reflexes of the enteric nervous system, mediated through the myenteric plexus. These...
