Heller myotomy is a surgical procedure [1] in which the muscles of the cardia (lower esophageal sphincter or LES) are cut, allowing food and liquids to pass to the stomach.It is used to treat achalasia, a disorder in which the lower esophageal sphincter fails to relax properly, making it difficult for food and liquids to reach the stomach.
The per-oral endoscopic myotomy, or POEM, is a minimally invasive surgical procedure for the treatment of achalasia wherein the inner circular muscle layer of the lower esophageal sphincter is divided through a submucosal tunnel. [1] This enables food and liquids to pass into the stomach, a process that is impaired in achalasia.
The upper esophageal sphincter surrounds the upper part of the esophagus. It consists of skeletal muscle but is not under voluntary control. Opening of the upper esophageal sphincter is triggered by the swallowing reflex. The primary muscle of the upper esophageal sphincter is the cricopharyngeal part of the inferior pharyngeal constrictor. [9]
For example, gastroesophageal reflux disease (GERD) with reflux esophagitis is treated with proton pump inhibitors. Esophageal rings or strictures may be treated with esophageal dilation. Simple observation may be considered, [5] especially if symptoms are minimal or absent. If symptoms are severe or persistent, peroral endoscopic myotomy (POEM ...
Nutcracker esophagus is characterized by high-amplitude peristaltic contractions that are frequently prolonged and cause dysphagia and chest pain. [6] HLES (hypertensive lower esophageal sphincter) is a rare manometric abnormality seen among individuals with dysphagia, chest pain, gastroesophageal reflux, and hiatal hernia. [7]
The lower esophageal sphincter is a muscular sphincter surrounding the lower part of the esophagus. The gastroesophageal junction between the esophagus and the stomach is controlled by the lower esophageal sphincter, which remains constricted at all times other than during swallowing and vomiting to prevent the contents of the stomach from ...
Esophageal dysphagia is a form of dysphagia where the underlying cause arises from the body of the esophagus, lower esophageal sphincter, or cardia of the stomach, usually due to mechanical causes or motility problems.
Stretta 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 just below the LES.
