Summary
Transient lower esophageal sphincter relaxation (TLESR) is key to reflux in both healthy people and GERD patients. New technology helps understand TLESR mechanisms, offering potential GERD therapies.
Area of Science:
- Gastroenterology
- Physiology
Background:
- The lower esophageal sphincter (LES) and crural diaphragm are primary antireflux barriers.
- Transient lower esophageal sphincter relaxation (TLESR), LES relaxation without a swallow, causes normal and pathological reflux.
- TLESR frequency is similar in healthy individuals and GERD patients, but more associated with acid reflux in GERD.
Purpose of the Study:
- To investigate the mechanisms underlying TLESR.
- To explore novel technologies for studying TLESR.
- To identify potential therapeutic targets for GERD based on TLESR mechanisms.
Main Methods:
- Utilized novel technology to study TLESR.
- Investigated pharmacologic and non-pharmacologic manipulation of receptors controlling TLESR.
Main Results:
- TLESR is a critical factor in both normal and GERD-related gastric reflux.
- Novel technologies provide new insights into TLESR mechanisms.
- Receptor manipulation influencing TLESR shows promise for GERD treatment.
Conclusions:
- Understanding TLESR mechanisms is crucial for GERD management.
- Targeting receptors involved in TLESR offers a potential therapeutic avenue for GERD.

01:24Esophagus
The esophagus, a muscular conduit linking the pharynx and stomach, measures roughly 10 inches (25.4 cm) and sits behind the trachea. It remains collapsed when not swallowing. The esophagus follows a predominantly straight path through the thoracic mediastinum and enters the abdominal cavity through a diaphragmatic opening known as the esophageal hiatus.
The movement of edibles from the pharynx into the esophagus is facilitated by the upper esophageal sphincter, which is formed primarily by the...

01:27Esophageal Achalasia
Esophageal achalasia is a chronic neurogenic disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent or ineffective peristalsis in the distal esophagus. This leads to a functional obstruction without a physical blockage, despite significant disruption of esophageal motility.EtiologyAchalasia is caused by degeneration of the myenteric (Auerbach's) plexus, specifically the loss of inhibitory ganglion cells that produce vasoactive intestinal peptide (VIP)...
01:25Gastroesophageal Reflux Disease
Gastroesophageal reflux disease (GERD) is the backward flow of stomach contents (acid, pepsin, or bile) into the esophagus, causing mucosal inflammation known as esophagitis. It results from failure of antireflux mechanisms, mainly the lower esophageal sphincter (LES), influenced by mechanical and physiological factors.Etiology and Risk FactorsGERD develops when LES function is weakened or when intra-abdominal pressure increases. Risk factors include aging, obesity, and sliding hiatal hernia,...
01:22Physiology of the Gastrointestinal System I: Ingestion and Propulsion
The physiology of the gastrointestinal system begins with ingestion as food enters the mouth.
01:25Deglutition
Swallowing, otherwise known as deglutition, facilitates the transport of food from the mouth to the stomach. It is a multifaceted process that involves both the tongue and the muscles of the throat and esophagus. Saliva and mucus aid in this process, which takes approximately 4 to 8 seconds for semi-solid or solid food and around 1 second for liquids or very soft food.
Swallowing can be divided into three stages: the voluntary phase, the pharyngeal phase, and the esophageal phase. Although the...

01:25Hiatal Hernia
A hiatal hernia is the abnormal protrusion of the stomach or other abdominal organs through the esophageal hiatus of the diaphragm into the thoracic cavity.Normally, the gastroesophageal junction (GEJ) lies below the diaphragm and is supported by the phrenoesophageal membrane, the diaphragmatic crura, and connective tissues. Weakening of these structures—due to aging, congenital defects like a short esophagus, or increased intra-abdominal pressure from coughing, obesity, pregnancy, or heavy...
