Summary
Systemic sclerosis disrupts normal gastric emptying, causing reverse flow from the antrum to the fundus. This finding suggests single-compartment models for gastric emptying may be inaccurate in such patients.
Area of Science:
- Gastroenterology
- Physiology
Background:
- Gastric emptying is crucial for nutrient digestion and absorption.
- Accurate measurement of gastric emptying is essential for diagnosing and managing gastrointestinal disorders.
Purpose of the Study:
- To investigate liquid-phase gastric emptying patterns in patients with systemic sclerosis.
- To compare gastric emptying in systemic sclerosis patients with healthy controls.
Main Methods:
- Radionuclide marker technique used for liquid-phase gastric emptying measurements.
- Analysis focused on subjects with distinguishable proximal stomach and antrum.
- Comparison between three healthy controls and two systemic sclerosis patients.
Main Results:
- Normal subjects exhibited expected fundus-to-antrum and pyloric passage of liquid.
- Systemic sclerosis patients showed significant antral retropulsion into the fundus.
- Observed abnormalities challenge the validity of single-compartment models in these patients.
Conclusions:
- Systemic sclerosis significantly alters gastric motility, leading to abnormal retropulsion.
- Standard single-compartment models for gastric emptying may yield misleading results in systemic sclerosis.
- Further research is needed to refine gastric emptying assessment in motility disorders.

What is Monogastric Digestion?
56.6K
The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.

Gross Anatomy of the Stomach
4.3K
The human stomach is a vital part of the digestive system, performing multiple functions. It is located within the peritoneum, a serous membrane that lines the abdominal cavity. The stomach plays a central role in processing food substances and interacts with other digestive organs through coordinated digestive processes. The stomach has a characteristic J-shape and is divided into four main regions. The cardia is the first section where the esophagus connects to the stomach and is the entry...

Gastric Phase of Digestion
4.2K
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...

Intestinal Phase of Digestion
10.1K
The intestinal phase of digestion is the third and final stage of the digestive process, occurring after the cephalic and gastric phases. It begins when chyme, a partially digested mixture of food and digestive enzymes, enters the small intestine from the stomach. This phase is crucial for nutrient absorption and involves complex hormonal and enzymatic interactions.
The arrival of the chyme in the small intestine distends the duodenum, which triggers the enterogastric reflex. This distension...

Gastric Motility
4.6K
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.

Gastric Emptying
5.5K
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...
