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 the organ. Zenker Diverticuli typically occur just above the Upper Esophageal Sphincter (UES). Killian-Jamieson diverticulum is a pulsion diverticulum, that protrudes through a lateral anatomic weak site of the cervical esophagus below the cricopharyngeus muscle, unlike the posterior, midline origin of a Zenker's diverticulum. Zenker diverticulosis is a pseudodiverticulosis. C Esophageal Diverticulectomy. The condition results from impeded transport of liquids, solids, or both from the pharynx to the stomach. Midthoracic. It is a very important part of the digestive system. Oesophageal diverticula are rare. This sphincter prevents the stomach contents from flowing into the esophagus. N2 - Imaging description A lower esophageal pulsion (epiphrenic) diverticulum contains some combination of air, fluid, and debris by CT chest. The barium outlines the esophagus, making abnormalities easier to see. It is one of the three types of esophageal diverticulum. There are two types of esophageal diverticula and both are usually acquired conditions. The thyroid gland develops as a diverticulum arising from a point on the tongue, demarcated as the foramen cecum. 1-Pharyngeal (Zenker's) 2-Midesophageal 3-Epiphrenic Human pathology Gastrointestinal tract diverticula Esophageal diverticula may occur in one of three areas of the esophagus: In both cases they are caused by altered motility which results in abnormal intraluminal pressure and the pushing of the oes … An esophageal diverticulum is an outpouching of mucosa through the muscular layer of the esophagus. Barrett's esophagus is a condition in which there is an abnormal (metaplastic) change in the mucosal cells lining the lower portion of the esophagus, from stratified squamous epithelium to simple columnar epithelium with interspersed goblet cells that are normally present only in the small intestine and large intestine.This change is considered to be a premalignant condition because it is . You do not always need treatment for esophageal diverticulum. These are pockets in the throat at the top of the esophagus and behind the upper esophageal sphincter, a valve at the upper end (throat) or lower end (stomach). Zenker's diverticulum is a condition where there is outpouching of the posterior pharyngeal constrictor muscles. [QxMD MEDLINE Link]. The type of surgery depends on the type of diverticulum. It is a very important part of the digestive system. Esophageal diverticula (pleural of diverticulum) are classified by their location within the esophagus: Zenker's diverticula (pharyngoesophageal) is the most common type of diverticula of the esophagus. This diverticulum consists of all 4 layers of the esophagus. Doctors diagnose all types of esophageal diverticula by doing a barium swallow (esophagram). Two types of pulsion diverticula are recognized: pharyngoesophageal (Zenker's) and epiphrenic. Patients typically present when they have symptoms of regurgitation or dysphagia. A diverticulum is a small pouch that can form in a weakened area of an organ. The condition results from impeded transport of liquids, solids, or both from the pharynx to the stomach. 10.3389/fped.2021.663705. An esophageal diverticulum known as a traction diverticulum occurs when there is an external force on the wall of the esophagus that creates the pouch. download scientific diagram | types of pharyngeal diverticula and their location. First, there's Zenker's diverticulum which is where the esophageal mucosa and submucosa of the esophagus slide through an area of muscle weakness right above the upper esophageal sphincter, forming a pouch-like structure sticking out from the wall of the esophagus. It's characterized by its anatomical location above the upper oesophageal sphincter. Medications, along with dietary and lifestyle changes, can help. There are different ways to categorize esophageal diverticulum. The Esophagus is the main tube that connects the mouth and the stomach. [1][4] They usually occur in the hypopharynx where there is a weakness in the area known as Killian's triangle. Pediatr Radiol. Esophageal diverticula are rare conditions that cause esophageal symptoms, such as dysphagia, regurgitation, and chest pain. Traction (true) diverticula results from contraction of periesophageal fibrous scar tissue, often secondary to a wound or previous surgery. This weakness is typically the result of excess pressure. Existing Patient. Esophageal Diverticula. Patients are at heightened risk if they are male, obese, over 50 years of age, Caucasian, a current or former smoker, and/or have a diagnosis of gastroesophageal reflux disease (GERD).Patients with Barrett's esophagus are at increased risk for a type of cancer called esophageal . An esophageal diverticulum can also be categorized based on location as pharyngeal (Zenker) diverticula, mid-esophageal diverticula, and epiphrenic diverticula. This condition presents a risk of infection, inflammation, aspiration, and pneumonia. Epidemiology. These type of esophageal diverticula tend to begin in the lower part of the esophagus and occur when increased pressure on the esophagus leads to inflammation which creates outward, or pulsating, pressure. An esophageal diverticulum can also be categorized based on location as pharyngeal (Zenker) diverticulum, mid-esophageal diverticulum, and epiphrenic diverticulum. Esophageal diverticula are abnormal pouches that arise from the wall of the esophagus. Oesophageal diverticula are rare. The remainder of the esophagus may be distended since epiphrenic diverticula are caused by partial distal esophageal obstruction. The condition typically begin with a herniation of the . This occurs as a consequence of increased pressure from within the esophagus, as seen with obstruction or failure of the esophageal muscles to move food through. The Esophagus is the main tube that connects the mouth and the stomach. They most commonly occur in middle-aged and older men and are classified based on localization, pathophysiology, and histological findings. Esophageal Diverticula. They usually occur in the hypopharynx where there is a weakness in the area known as Killian's triangle 11). As is common practice, Zenker diverticulum, a type of diverticulum that arises from the posterior hypopharynx, is also discussed in this. Traction Diverticula This type of esophageal diverticula involves inflammation of the tissues on the outside and surrounding the esophagus. They are located in the back of the throat above the esophagus. of the diverticulum is important to confirm the diagnosis of true diverticulum and rule out communicating duplication cyst which may show heterotopic mucosa. Dysphagia Dysphagia is difficulty swallowing. Zenker's diverticulum is a specific type of esophageal outpouching or diverticulum. Esophageal Dysphagia. It can be asymptomatic or cause dysphagia Dysphagia Dysphagia is difficulty swallowing. A number of distinct types of esophageal diverticula are found clinically with distinct locations, etiologies, and clinical consequences. 1. classified esophageal diverticula into (1) traction type, usually found in the midthoracic region, the result of cicatricial contraction of the esophageal wall caused by tuberculous or other forms of chronic lymphadenitis. Traction was the possible mechanism in 27% of midesophageal diverticula. The aperture between the esophagus and the diverticulum is not always present due to the plane of section. Zenker Diverticuli typically occur just above the Upper Esophageal Sphincter (UES). 4. This article focuses on diverticula of the esophagus. Zenker's diverticula are usually located in the back of the throat, just above the esophagus Midthoracic diverticula, in the mid-chest [1] These diverticula are made up of the mucosal and submucosal lining, herniating through a weakness in the muscularis layer of . Diverticula are pouch-like dilatations of the esophageal wall and may be congenital or acquired. Traction diverticula are usually . Much has been written during the past twenty years regarding esophageal diverticula. They are classified according to their location and characteristic pathophysiology into three types: epiphrenic diverticulum, Zenker's diverticulum, and Rokitansky diverticulum. Esophageal diverticula can affect people of all ages, although most cases occur in middle-aged and elderly individuals. Zenker's diverticula (pharyngoesophageal) is the most common type of diverticula of the esophagus. An esophageal diverticulum is an outpouching of mucosa through the muscular layer of the esophagus. 1991. Esophageal diverticula are either: true diverticula: include all esophageal layers; false diverticula: contain only mucosa and submucosa herniating through the muscular layer (e.g. A number of distinct types of esophageal diverticula are found clinically with distinct locations, etiologies, and clinical consequences. They are rare in dogs and cats. 855-855-6484. These weakened areas form a pouch, which can trap food. Histologically, there are two types of esophageal diverticula: true diverticulum which consists of all layers of the esophagus and false diverticulum which includes only two layers, mucosa and submucosa. Pharyngeal diverticula are considered false diverticula. This type develops near the top of the esophagus. This pocket-like structure can appear anywhere in the esophageal lining between the throat and stomach. A number of conditions can develop in the esophagus such as; Esophageal cancer, Gastroesophageal reflux disease, Diverticulum of the esophagus, and more. They are most commonly seen at the pharyngo-oesophageal junction (Zenker's diverticula) or at the distal oesophagus (epiphrenic diverticula). When food becomes trapped in the pouch, patients sense something is stuck, and this can lead to difficult or painful swallowing. Dysphagia Dysphagia is difficulty swallowing. The 3 classifications of esophageal diverticula. 4 Pulsion Diverticula Also referred to as epiphanic diverticula, these pouches occur in the lower part of the esophagus. Neonates Dysphagia Dysphagia is difficulty swallowing. It is most commonly seen in elderly men, usually more than 60 years old, often 75 years older. The . Two types of pulsion diverticula are recognized: pharyngoesophageal (Zenker's) and epiphrenic. The outcome depends on multiple factors, such as the age at presentation, location of the diverticulum, the type of diver-ticulum and associated oesophageal dysmotility. You have been seen by a Duke provider for gastroenterology care within the last three years or you need to reschedule an appointment. The diverticulum can compress the trachea. They are classified according to their location and characteristic pathophysiology into three types: epiphrenic diverticulum, Zenker's diverticulum, and Rokitansky diverticulum. It can be asymptomatic or cause dysphagia. These include: Zenker's diverticulum. The esophagus is the tube connecting the mouth with the stomach. Esophageal diverticula in childhood associated with strictures from unsuspected foreign bodies of the esophagus. Ref. The lining of the esophagus pushes backward, so some food stays in the pouch rather than moving down into the stomach. It can be asymptomatic or cause dysphagia. The condition results from impeded transport of liquids, solids, or both from the pharynx to the stomach. One of the most common types of esophageal diverticula is called Zenker's diverticulum. If, however, the pouch in your esophagus becomes overly large or begins causing symptoms, surgery may be needed to remove the pouch and repair your esophageal wall. Epiphrenic diverticulum, also known as a pulsion diverticulum, is a rare type of esophageal diverticulum occurring in the distal 10 centimeters (CM) of the esophagus most commonly 4cm to 8 cm above the gastric cardia. An esophageal diverticulum is an outpouching of mucosa through the muscular layer of the esophagus. The condition results from impeded transport of liquids, solids, or both from the pharynx to the stomach. Specific esophageal motor disorders were more frequent in association with diverticula of the distal third than in midesophageal diverticula, suggesting that they result from a pulsion mechanism. Treating Esophageal Diverticulum. a) zenker diverticula, b) laimer diverticula, c) killian-jameison diverticula and d) lateral pharyngeal diverticula. A number of conditions can develop in the esophagus such as; Esophageal cancer, Gastroesophageal reflux disease, Diverticulum of the esophagus, and more. Congenital esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) is a serious digestive malformation with an incidence of ~1/2000-4500 ( 1 ). Occurring in the top part of the esophagus, a Zenker's diverticulum is caused by abnormal tightening of the upper esophageal sphincter between the lower pharynx (throat) and the upper esophagus. The Midthoracic diverticula are situated in the mid chest Oesophageal diverticulum is divided into two types based on the aetiology: the pulsion and the traction diverticula. This is the most common type of esophageal diverticulum. [1] It is an outpouching of the esophageal mucosa and is usually asymptomatic. Mid-esophageal diverticula (area that corresponds to the packet of larger subcarinal nodes and hence frequently called "subcarinal" ) are almost exclusively traction type, and epiphrenic diverticula are usually pulsion type. What types of esophageal diverticula are there? The second category, traction diverticulum, results from inflammation and fibrosis in adjacent lymph nodes and is composed of all layers of the esophageal wall (true diverticulum). Available for iPhone, iPad, Android, and Web. Acquired diverticula are of two types: pulsion or traction. 2003 Apr.

Barrett's esophagus is a change in the tissue of the esophagus that is related to long-term acid reflux.. 38(4):E9. Zenker's diverticula are pouches that develop close to the upper esophageal sphincter. Since Ludlow, in 1764, first described a diverticulum of the esophagus, many contributions have been made as to topography, classification, etiology, and treatment. Occasionally, however, even the pulsion type has been found in this region; 4. The most common symptoms are dysphagia, regurgitation, thoracic pain, and pulmonary manifestations related to aspiration. An esophageal diverticulum is an outpouching of mucosa through the muscular layer of the esophagus. It happened to be his wedding anniversary, but perhaps the phone wouldn't ring. Traction diverticula result from inflammation in the chest cavity in close proximity to the esophagus. Traditionally, esophageal diverticula are classified as either traction diverticula, which occur primarily in the midesophagus, or pulsion diverticula, which typically occur in the upper or lower esophagus. The second category, traction diverticulum, results from inflammation and fibrosis in adjacent lymph nodes and is composed of all layers of the esophageal wall (true diverticulum). Type C Esophageal Explore More. There are different esophageal disorders, each having its own causes, symptoms, and treatments. The condition results from impeded transport of liquids, solids, or both from the pharynx to the stomach. AP view shows diverticulum (arrow) originating laterally. A pulsion diverticulum, the most common type, occurs due to increased intraluminal pressure related to esophageal dysmotility, is usually encountered in the middle to lower thirds of the esophagus, and often occurs with multiple other pulsion diverticula. Esophageal diverticula may be classified by presumed pathophysiology (traction versus pulsion), type (true versus false), or esophageal location. All are true diverticula and thus are surrounded by all histological layers of the esophageal wall. Esophageal diverticula are weak parts of the esophagus that pouch outward. The most common type is GERD. This causes a bulge to form, and over time pressure will cause a diverticulum to develop. Pulsion diverticula are caused by increased intraluminal pressure or deep esophageal inflammation, which can lead to . In this test, people are given barium in a liquid before x-rays are taken. Esophageal Diverticula.

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. The most common type of esophageal diverticula is Zenker diverticulum , which extends posteriorly in the hypopharynx All patients underwent thoracoscopic esophageal diverticulectomy (operation time: 1. False diverticulum = herniation of mucosa and submucosa through . In practice, many midesophageal diverticula are pulsion type 77 and are due to increased intraluminal pressure causing "ballooning" of .
