The 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.

What is the flap between the stomach and esophagus?

The lower esophageal sphincter (or LES) is a muscle that separates the esophagus from the stomach. It acts like a valve that normally stays tightly closed to prevent contents in the stomach from backing up into the esophagus.

Where is the gastroesophageal sphincter?

The lower esophageal sphincter, or gastroesophageal sphincter, surrounds the lower part of the esophagus at the junction between the esophagus and the stomach. It is also called the cardiac sphincter or cardioesophageal sphincter, named from the adjacent part of the stomach, the cardia.

What is the Nissen procedure?

Laparoscopic anti-reflux surgery for GERD may involve a procedure to reinforce the lower esophageal sphincter, called Nissen fundoplication. In this procedure, the surgeon wraps the top of the stomach around the lower esophagus after reducing the hiatal hernia, if present.

What is TIF surgery?

Transoral incisionless fundoplication (TIF) is an advanced endoscopy procedure that provides relief from acid reflux (heartburn) symptoms associated with chronic gastroesophageal reflux disease (GERD). Our skilled gastroenterologists offer TIF as a way to treat GERD without surgery.

How serious is achalasia?

What is gastroesophogeal reflux repair or wrap surgery?

The gastroesophogeal reflux repair or “wrap” surgery corrects Gastroesophogeal Reflux Disease (GERD). GERD is a digestive disorder that causes acids in the stomach to flow back up into the esophagus, the “foodpipe” or swallowing tube that carries food from the mouth to the stomach.
