Esophageal Hiatus Contents Mnemonics
Aug 17, 2015 The diaphragm has 3 main hiatuses – the hiatus of the inferior vena cava (IVC), the esophageal hiatus, and the aortic hiatus. The IVC passes through the diaphragm at the level of T8 (I “ate”), the esophagus passes at the level of T10 (“10 Eggs”). The right crus and lower esophageal sphincter together form the esophagogastric junction, which acts as a barrier against the reflux of gastric content into the esophagus. Hiatus hernias are subdivided into sliding hernias (85-95%) and paraesophageal hernias (5-15% overall). The esophageal hiatus is the opening in the diaphragm through which the esophagus passes from the thoracic to abdominal cavity. It is one of three apertures in the diaphragm and is located in the right crus. It is situated in the muscular part of the diaphragm at the level of T10 and is elliptical in shape.

The esophagus carries food down the chest cavity and empties it into the top of the stomach. Therefore the stomach lies in the abdominal cavity, which is separated from the chest cavity by a large flat sheet of muscle known as the diaphragm.A small opening in the diaphragm allows the esophagus to pass.
This is known as the esophageal opening or esophageal hiatus and towards the middle of the diaphragm, slightly to the left. It is only wide enough for the esophagus but can sometimes become enlarged. In these cases, the stomach can sometimes get trapped and pinched in this opening.
This is known as a hiatal hernia. What Happens in A Hiatal Hernia?The diaphragm ensures that abdominal organs cannot enter the chest cavity. It serves as a border and barrier but certain structures do not to pass through across the chest and abdominal cavities. The esophagus is one such example. Large blood vessels like the aorta and vena cava also need to pass between the chest and abdominal cavities.Therefore small openings have to be present in the diaphragm to allow these structures to pass through. Other organs in the abdomen should not be able to fit in these openings or protrude through into the chest cavity.
However, this is what occurs in a hiatal hernia. The stomach protrudes into the chest cavity through the esophageal opening.Even when the esophageal opening (esophageal hiatus) is abnormally enlarged, the stomach barely fits through it. Therefore only a portion of the upper region of the stomach may protrude through. It is a tight squeeze and the stomach becomes trapped in the esophageal opening. It may also be pinched by the muscles around this opening.There are several reasons why this enlargement of the esophageal hiatus may occur. Any persistently high negative pressure in the chest cavity or increased abdominal pressure may cause widening of this opening. An injury, forceful and persistent coughing, vomiting or straining to pass stool as well as lifting heavy objects may be responsible.Some people are born with an unnaturally large hiatus and advancing age may cause the muscles around the hiatus (opening) to become weak.
Pregnancy may also be a factor in causing a hiatal hernia as the enlarged uterus increases pressure within the abdomen. Obesity also increases intra-abdominal pressure and a hiatal hernia tends to be more common in obese people.Read more on. How Do You Know If You Have A Hiatal HerniaMost hiatal hernias are asymptomatic meaning that there are no signs and symptoms. In fact hiatal hernias are often discovered incidentally during certain diagnostic investigations despite a person not having experienced any symptoms. However, some hiatal hernias may present with the following signs and symptoms.It is important to note the signs and symptoms of a hiatal hernia are similar to many other stomach and upper abdominal conditions. Most of these symptoms occur because the lower esophageal sphincter (LES) is compromised with the protrusion.
The LES normally prevents the stomach contents from flowing backward into the esophagus. HeartburnHeartburn is the most common symptom of a hiatal hernia when there are symptoms.
This is a burning chest pain or discomfort caused by the acidic stomach contents in the esophagus (acid reflux). Sometimes existing acid reflux is not due to the hiatal hernia but some other condition.When hiatal hernia occurs in these conditions, then it worsens the reflux and symptoms like heartburn. The reflux in hiatal hernia tends to increase in severity with larger hernias.
Therefore heartburn is worse with larger hernias than with smaller hernias. Regurgitation is where food (undigested or partially digested) from the stomach comes up the esophagus and reaches the throat or mouth. Unlike with vomiting, regurgitation is not as forceful a process. The larger the hiatal hernia, the more severe the regurgitation.It can occur even when a person is upright but is more likely to occur when bending over or lying flat, especially after eating.
Regurgitation is also more likely to occur after larger meals and is usually accompanied by heartburn. Chest and Abdominal PainApart from heartburn (burning pain in the chest), there may also be other types of chest pain and abdominal pain as well. This pain is more likely to occur in the lower chest or upper abdomen where the esophageal opening lies.
It arises from the squeezing or pinching of the trapped stomach in this esophageal opening. The pain eases once the stomach moves out of the opening and back to its normal position.
These episodes of pain may occur as attacks that can last from minutes to hours. Abnormal FullnessA feeling of fullness or bloating after eating even a small meal can also occur with a hiatal hernia.
This is not an uncommon symptom to occur in most stomach conditions. Portion of the stomach becomes compressed when it becomes trapped in the esophageal hiatus. It tends to accompany the other symptoms like heartburn.
Difficulty SwallowingThe herniation can cause an obstruction of the area between the esophagus and stomach. This can cause difficulty swallowing (dysphagia), particularly with solids. It may also occur as a complication of long term acid reflux which may be caused by the hiatal hernia.
Difficulty swallowing is more commonly seen with a rolling hiatal hernia. Other SymptomsOther signs and symptoms that may also occur with a hiatal hernia includes:. Excessive belching. Vomiting and sometimes bloody vomit. Blood in the stool which may cause dark to black tarry stools (melena).
Plummer–Vinson syndromeOther namesPaterson–Brown–Kelly syndrome, Sideropenic dysphagia,Plummer–Vinson syndrome is a characterized by,. Treatment with iron supplementation and mechanical widening of the esophagus generally provides an excellent outcome.While exact data about the epidemiology is unknown, this syndrome has become extremely rare. The reduction in the prevalence of Plummer–Vinson syndrome has been hypothesized to be the result of improvements in nutritional status and availability in countries where the syndrome was previously described.
It generally occurs in women. Its identification and follow-up is considered relevant due to increased risk of of the. Angular stomatitisPatients with Plummer–Vinson syndrome often have a burning sensation with the tongue and oral mucosa, and atrophy of lingual papillae produces a smooth, shiny, red, dorsum of the tongue. Symptoms include:. (difficulty swallowing). (painful swallowing).Serial contrasted gastrointestinal or upper-gastrointestinal may reveal the web in the esophagus.demonstrate a hypochromic that is consistent with an iron-deficiency anemia.
Biopsy of involved mucosa typically reveals epithelial atrophy (shrinking) and varying amounts of submucosal chronic inflammation. Epithelial atypia or may be present. It may also present as a post-cricoid malignancy which can be detected by loss of laryngeal crepitus. Laryngeal crepitus is found normally and is produced because the cricoid cartilage rubs against the vertebrae.Causes The cause of Plummer–Vinson syndrome is unknown; however, factors and may play a role. It is more common in women, particularly in middle age, with a peak age over 50 years. In these patients, esophageal risk is increased; therefore, it is considered a process. The condition is associated with, inflammation of the lips , and.Esophageal webs in Plummer–Vinson syndrome are found at upper end of esophagus (post cricoid region) and may be found at the lower end of.
Ascorbic-acidTreatment is primarily aimed at correcting the. Patients with Plummer–Vinson syndrome should receive supplementation in their. This may improve dysphagia and pain. If not, the web can be dilated with esophageal bougies during to allow normal swallowing and passage of food. Complications There is risk of perforation of the esophagus with the use of dilators for treatment.

Furthermore, it is one of the risk factors for developing of the oral cavity, esophagus, and hypopharynx. Prognosis Patients generally respond well to treatment.
Iron supplementation usually resolves the anemia, and corrects the (tongue pain). History The disease is named after two Americans: the and the surgeon. It is occasionally known as Paterson-Kelly or Paterson-Brown Kelly syndrome in the UK, after. However, Plummer–Vinson syndrome is still the most commonly used name. See also.References.
