Cause of Zenker’s Diverticulum. The cricopharyngeus muscle is located at the bottom of the throat. This muscle is normally contracted, to prevent reflux, or the flow of food and acid backwards from the esophagus into the throat. When this muscle is overactive, the tissue above it stretches and dilates. Diverticula of the esophagus are a rare entity, with a prevalence that ranges between % and 4%. 1,2 Esophageal diverticula are classified according to their location along the esophagus (pharyngoesophageal, midesophageal, or epiphrenic), and the mechanism of formation (pulsion or traction). Most common diverticula are those located in the pharyngoesophageal and epiphrenic .
Diverticulosis is simply the presence of these tiny bulges or pockets (diverticula) in your colon. They usually don’t cause any symptoms or need to be treated. However, diverticulosis can lead to diverticulitis. Diverticulitis is inflammation (swelling) and infection in one or more diverticula. Diverticulum, any small pouch or sac that forms in the wall of a major organ of the human body. Diverticula form most commonly in the esophagus, small intestine, and large intestine and are most often a problem in the latter organ. Middle-aged and older people are particularly susceptible to the.
A case of congenital pulsion diverticulum of the lower esophagus with a long history of about 22 years duration is presented. Resection was carried out with successful end . Diverticula of the esophageal body are most commonly located in the middle or lower third of the esophagus. Diverticula located near the diaphragmatic hiatus are called epiphrenic diverticula. Congenital bronchopulmonary-foregut malformations can communicate with the esophagus and present as esophageal diverticula. 25 Traction diverticula are.

Arthur Localio. Esophageal diverticula are rare and have been described in all age groups, but they are most commonly seen in adults. Motor abnormalities of the esophagus are often associated with esophageal diverticula, but the belief that all diverticula are due to a motor disorder of the esophagus is not established with certainty.

Large pulsion diverticulum of the middle third of the thoracic by: 4. When diverticula of hollow viscera are drawn upon by outside adhesions their fundal margins become “spiky”, as in the fully developed condition seen in colon diverticulitis.
How different from the smooth outline seen in the typical mid-thoracic œsophageal diverticulum (Fig. 1).Cited by: 9. Pulsion diverticula, often less than 3–5 cm in size, is located in the midportion of the oesophagus.
These are by definition pseudo‐diverticula. These are by definition pseudo‐diverticula. Epiphrenal diverticula that are usually 10–20 cm big diverticula located in the most distal part of the oesophagus. Abstract. Esophageal diverticula are localized projections of the lumen of the gullet. They are distinguished from pseudo- or functional diverticula by the fact that the sacculation of the wall has a constant localization and is limited to a relatively small part of the esophageal circumference.
Esophageal diverticula may occur in one of three locations: above the upper esophageal sphincter, in the mid-esophagus, and just above the lower esophageal sphincter.
Zenker's diverticulum is a pouch that protrudes posteriorly above the upper esophageal sphincter (Fig. An esophageal diverticulum is an outpouching of mucosa through the muscular layer of the esophagus.
It can be asymptomatic or cause dysphagia and regurgitation. Diagnosis is made by barium swallow; surgical repair is rarely required. Esophageal diverticula can affect people of all ages, although most cases occur in middle-aged and elderly individuals.
Overall, esophageal diverticula are rare, showing up in less than 1 percent of upper gastrointestinal X-rays and occurring in less than 5 percent of patients who complain of dysphagia (difficulty in swallowing). Diverticulosis is when pockets called diverticula form in the walls of your digestive tract.
The inner layer of your intestine pushes through weak spots in the outer lining. This pressure makes.
Most of the esophageal diverticula are pulsion diverticula, which protrudes from a weak point of the esophageal musculature. This is common secondary to esophageal obstruction, abnormal motility and impaired relaxation of the esophagus which leads to increased pressure within the esophagus.
Esophageal diverticula comprise a rare condition that causes dysphagia, regurgitation, and chest pain as they progress.
The pathophysiology of the diverticula varies according to their location in the esophagus (i.e., epiphrenic, Zenker’s, and Rokitansky).
Interventional treatment should be considered for symptomatic cases. An esophageal diverticulum is a pouch in the lining of your esophagus.
If it grows large enough, it can cause a range of symptoms. We'll go over the different types of esophageal diverticula. Mid-esophageal Diverticulum typically occur somewhere between the UES and the Lower Esophageal Sphincter (LES).
Motor dysfunction of the esophageal muscularis propria results in an esophageal segment which cannot conduct peristaltic waves and thus increased pressure and diverticulum-generation above the restriction point. Case Discussion. This case illustrates a proximal esophageal diverticulum that has arises further below the level of the pharyngoesophageal junction and, therefore, is not a Zenker having a posterior origin, it also appears to not fit as a Killian-Jamieson diverticulum, which arises below the cricopharyngeal muscle anteriorly and laterally.
Epiphrenic diverticula are outpouchings of the distal esophagus just above the diaphragm that appear as thin-walled, air or air-fluid filled structures adjacent to the distal esophagus. An epiphrenic diverticulum can mimic a hiatal hernia at CT (Figures and ). Zenker's Diverticulum: What is it and How do you Treat it?Zenker's Diverticulum is a rare, benign throat disorder seen mainly in elderly people.
It is an outpouching that develops in a weakened area at the back of the throat. Although Zenker's Diverticulum is the most common type of esophageal diverticulum, the true incidence is difficult to determine because so many people with. Epidemiology.
They can occur in all ages but more frequent in adults and elderly people. Pathology. Esophageal diverticula are either: true diverticula: include all esophageal layers; false diverticula: contain only mucosa and submucosa herniating through the muscular layer (e.g.
Zenker diverticulum); Esophageal diverticula are classified according to the mechanism of formation into. These videos are available to you free of charge. In return, we kindly ask you to participate in this 3-minute survey below to help us scientifically evalua.
The aetiology, pathology and radiology of epiphrenic diverticula of the oesophagus are discussed and the literature reviewed with emphasis on those diverticula of congenital origin. Two cases of ep. An esophageal diverticulum is a pouch that protrudes outward in a weak portion of the esophageal lining.
This pocket-like structure can appear anywhere in the esophageal lining between the throat and stomach. Esophageal diverticula can affect people of all ages, although most cases occur in middle-aged and elderly individuals.Killian-Jamieson diverticulum- is very similar to a pharyngeal esophageal diverticulum, differing in the fact that the pouching is below the cricopharyngeal muscle.
 Colonic diverticula: Although found incidentally during colonoscopy, these diverticula may become infected (see diverticulitis) and can perforate, requiring surgery. comment: Diverticula (Figure 1, arrow) may occur anywhere in the alimentary are a bulge in a weakened portion of the wall that forms a pocket that is continuous with the lumen.
Diverticula are lined by the same type of epithelium as the organ in which they originate, which in the esophagus is squamous epithelium, and the epithelium is continuous with the normal epithelium of .
