Although POEM does not allow for a fundoplication at the time of myotomy, the intact phrenoesophageal ligaments and preservation of the longitudinal esophageal muscle fibers are believed to reduce the incidence of GERD after POEM.

He published a book, The Longitudinal Muscle in Esophageal Disease about his conclusions concerning the esophagus obtained from a lifetime of experience in radiology. Among his conclusions was that achalasia and barrett's esophagus are not unique diseases, as has been traditionally thought, but a subset of hiatus : November 9,Green Bay, Wisconsin.

Esophagus Spasm. Diffuse esophageal spasm (DES) is a clinical syndrome characterized by symptoms of sub-sternal distress, dysphagia, or both and an increased incidence of nonperistaltic esophageal contractions on manometry.

Gastro Esophageal Reflux Disease (GERD) is understood to be a failure of the anti reflux barrier, allowing abnormal reflux of gastric contents to the esophagus.

It is a mechanical disorder which is caused by a defective lower esophageal sphincter, a gastric emptying disorder or failed esophageal peristalsis.

A local longitudinal slice of esophageal muscle has shortened from length L* to length L as a result of local longitudinal contraction. For convenience, only one muscle layer is shown.

The longitudinal muscle has been shown to contract and stiffen the esophageal wall at swallowing thereby promoting normal transit. In patients with hiatal hernia and GERD, the distal end of the longitudinal muscle of the esophagus has been shortened and dislocated into the thoracic cavity.

Esophageal motility disorders are disorders of the muscle that lines the esophageal wall. In achalasia, the neurons of the myenteric plexus are destroyed by chronic inflammation which results in esophageal aperistalsis and poor relaxation of the lower esophageal sphincter. 4,5 The trigger for the chronic inflammation is unknown but is likely an.

Muscle is arranged in two layers: one in which the muscle fibers run longitudinal to the esophagus, and the other in which the fibers encircle the esophagus. These are separated by the myenteric plexus, a tangled network of nerve fibers involved in the secretion of mucus and in peristalsis of the smooth muscle of the : Oesophageal arteries.

Arthur Stiennon has published the full text of his book at this site. The volume provides extensive references to research that both raises questions and provides insight into the neuromuscular function of the esophagus and esophageal disease.

Esophageal Disorders Definition The esophagus is a tube that connects the back of the mouth to the stomach. Abnormalities of the esophagus generally fall into one of four categories: structural abnormalities, motility disorders, inflammatory disorders, and malignancies.

Description The main function of the esophagus is to move food from the back of the. The muscle tissue of esophagus consists of striated muscle (skeletal) in the upper third, mixture of skeletal and smooth muscle in the middle third, and pure smooth muscle in the lower third.

These muscle contents arrange into endo‐circular and exo‐longitudinal sub‐bilayers to play an important role in propelling the swallowed food or Author: Yabin Zhu, Mi Zhou, Ruixia Hou.

Longitudinal muscle fibers are gathered laterally in upper portion of esophagus, but these fibers expand and surround all surfaces at lower sides, becoming strongest in lower third part of esophagus.

Circular muscle fibers are located under longitudinal muscle, and Author: Murat Ferhat Ferhatoglu, Taner Kıvılcım. This may occur because of weakening of the anchors of the esophagus to the diaphragm, from years of longitudinal esophageal muscle contractions or from increased pressure in the abdomen.

Paraesophageal hernias — This occurs when part of the stomach squeezes through the hiatus, placing it next to the esophagus. Unlike sliding hernias. Abstract. As surgeons address foregut disease in their patients with different procedures, a review of relevant anatomy and physiology of the esophagus and LES will complement discussion with their patients and : Lawrence F.

Johnson. Gastroesophageal reflux disease affects 20%–30% of Western populations and is one of the most common diseases of mankind.

A subset of these patients present with esophageal chest pain, which can mimic angina. Additional etiologies of this “noncardiac” chest pain may involve esophageal spasms from both circular and longitudinal muscles, inflammatory processes of the esophagus (infections.

Generally, esophageal squamous cell carcinoma is a disease of lower socioeconomic groups. Lower socioeconomic status is associated with higher incidence worldwide. Uncommon Exposures and Diseases Although there are unusual or rare causes of esophageal cancer, they are worth mentioning because of their epidemiological implications.

Peristalsis propels the bolus through the esophagus and toward the stomach. The circular muscle layer of the muscularis contracts, pinching the esophageal wall and forcing the bolus forward. At the same time, the longitudinal muscle layer of the muscularis also contracts, shortening this area and pushing out its walls to receive the bolus.

In normal patients, there is synchrony in timing and amplitude of contraction between the circular and longitudinal muscle layers. Compared to normal subjects, patients with achalasia, diffuse esophageal spasm, and nutcracker esophagus have increased baseline muscle thickness on endoscopic ultrasound (EUS) that correlates with severity of disease.

The esophagus is a muscular tube that is normally cm long and cm wide. The layers of the esophagus are the same as elsewhere in the gi tract with a mucosa, submucosa, circular and longitudinal layers of muscle, and adventitia.

However, unlike the rest of the gi tract, the esophagus has no serosa. The circular muscle layer of the muscularis contracts, pinching the esophageal wall and forcing the bolus forward.

At the same time, the longitudinal muscle layer of the muscularis also contracts, shortening this area and pushing out its walls to receive the by: 1. The normal esophageal mucosa is pale pink, smooth, and glistening (Figure 1).

The cat’s caudal thoracic esophagus has circular rings, which denote the section comprised of smooth muscle. Longitudinal mucosal folds, which disappear when the lumen is fully insufflated, are encountered in.

The digestive system is innervated through its connections with the central nervous system (CNS) and by the enteric nervous system (ENS) within the wall of the gastrointestinal tract. The ENS works in concert with CNS reflex and command centers and with neural pathways that pass through sympathetic ganglia to control digestive by: Achalasia of the oesophagus (48, 49) and Hirschsprung’s Disease of the rectum and colon have bowel containing no ganglion cells also known as enteric neurones responsible for the nervous control of gut movements.

Both are of unknown aetiology. Chagas’ disease, or South American trypanosomiasis, is similar in that the oesophagus and colon are aganglionic, but the whole bowel is affected and. (C) Contraction of the longitudinal and circular muscles in the receiving segment (D) Relaxation of the circular muscle and contraction of the longitudinal muscle in the receiving segment (E) Contraction of the longitudinal muscle and relaxation of the circular muscle in the propulsive segment.

Relaxation of the muscle occurs distal to the bolus, so that the food can go forward. This is mediated by VIP / NO. Contraction of Longitudinal Muscle layer also occurs distal to bolus, because longitudinal contraction causes widening of the GI lumen.

Contraction of the muscle occurs proximal to the bolus, in order to propel the bolus forward. The esophagus is a muscular tube approximately 20 to 25 cm long.

The majority of the esophagus is located in the mediastinum, posterior and slightly lateral to the trachea, with smaller cervical and abdominal components as well, as shown in Figure There is an outer longitudinal muscle layer and an inner circular muscle layer.

In most cases, esophageal cancer is a treatable disease, but it is rarely curable. The overall 5-year survival rate in patients amenable to definitive treatment ranges from 5% to 30%.

The occasional patient with very early disease has a better chance of survival.
