Bolus
|
Is a small rounded mass of a substance, especially of chewed food at the moment of swallowing. It moves from the mouth to the stomach.
|
 Fauces |
due to the contraction of the palatoglossal muscles constricts the isthmus, and is essential to swallowing (deglutition).
|
 Esophagus |
Is the part of the alimentary canal that connects the throat to the stomach; the gullet. In humans and other vertebrates it is a muscular tube lined with mucous membrane.
|
 Upper Esophageal Sphincter (UES) |
Is that area of the upper digestive tract that forms a barrier between the esophagus and the pharynx, but that intermittently opens and closes to allow passage of contents during various physiologic events.
|
 Lower Esophageal Sphincter (LES) |
Is a bundle of muscles at the low end of the esophagus, where it meets the stomach. When the LES is closed, it prevents acid and stomach contents from traveling backwards from the stomach.
|
 Esophageal Hiatus |
Is a hole in the diaphragm through which the esophagus and the vagus nerve pass. It is located in the right crus, one of the two tendinous structures that connect the diaphragm to the spine.
|
 Hiatal Hernia |
Occurs when part of your stomach pushes upward through your diaphragm. Your diaphragm normally has a small opening (hiatus) through which your food tube (esophagus) passes on its way to connect to your stomach.
|
 Gastroesophageal Reflux Disease (GERD) |
Is a digestive disorder that affects the lower esophageal sphincter (LES), the ring of muscle between the esophagus and stomach
|
 Stretta Treatment (Procedure) |
Is a minimally invasive endoscopic procedure for the treatment of gastroesophageal reflux disease (GERD) that delivers radiofrequency energy in the form of electromagnetic waves through electrodes at the end of a catheter to the lower esophageal sphincter (LES) and the gastric cardia - the region of the stomach
|
 Stretta Catheter |
Trans-oral Stretta catheter system uses a proprietary application of RF energy that is low-power (5 Watts) and generates low temperatures (65°C to 85°C) during a series of 14 one-minute cycles which remodel the lower esophageal sphincter (LES) muscle and gastric cardia.
|
 Bard Endoscopic Suturing System |
A flexible endoscope with a miniature sewing machine-like device inside the tip. At the junction of the esophagus and stomach, sutures are placed on both sides of the esophagus, and the ends of the suturing material are tied together to create a pleat - which helps prevent acid from flowing back up the esophagus.
|
 Endoscope |
Is an instrument that can be introduced into the body to give a view of its internal parts.
|
|
Endoscopy
|
Is a procedure in which your doctor uses specialized instruments to view and operate on the internal organs and vessels of your body. It allows surgeons to view problems within your body without making large incisions.
|
 Stomach |
The internal organ in which the major part of the digestion of food occurs.
|
|
Fundus (of the stomach)
|
Is located at the uppermost section of the stomach. Its function is to store accumulated gas, which is produced as a by product of digestion, and to store extra food as needed.
