Esophageal webs are thin 2–3 mm (0.08–0.12 in) membranes of normal esophageal tissue consisting of mucosa and submucosa that can partially protrude/obstruct the esophagus. They can be congenital or acquired. Congenital webs commonly appear in the middle and inferior third of the esophagus, and they are more likely to be circumferential with ...
Esophagogastroduodenoscopy. Treatment. Ablation with argon plasma coagulation or radiofrequency ablation. Frequency. 1 - 12% [1] Esophageal inlet patch or heterotopic gastric mucosa of the upper esophagus or gastric inlet patch is one or more areas of tissue resembling stomach tissue which is found in the upper portion of the esophagus.
The pharynx (pl.: pharynges) is the part of the throat behind the mouth and nasal cavity, and above the esophagus and trachea (the tubes going down to the stomach and the lungs respectively). It is found in vertebrates and invertebrates, though its structure varies across species. The pharynx carries food to the esophagus and air to the larynx.
The esophagus carries food through the throat to the stomach. [5] Adenoids and tonsils help prevent infection and are composed of lymph tissue. The larynx contains vocal cords, the epiglottis (preventing food/liquid inhalation), and an area known as the subglottic larynx, in children it is the narrowest section of the upper part of the throat.
Swallowing. Swallowing, also called deglutition or inglutition[1] in scientific contexts, is the process in the body of a human or other animal that allows for a substance to pass from the mouth, to the pharynx, and into the esophagus, while shutting the epiglottis. Swallowing is an important part of eating and drinking.
Esophageal rupture. Esophageal rupture is a rupture of the esophageal wall. Iatrogenic causes account for approximately 56% of esophageal perforations, usually due to medical instrumentation such as an endoscopy or paraesophageal surgery. [1] The 10% of esophageal perforations caused specifically by vomiting are termed Boerhaave syndrome.
Laryngopharyngeal reflux (LPR) or laryngopharyngeal reflux disease (LPRD) is the retrograde flow of gastric contents into the larynx, oropharynx and/or the nasopharynx. [4] [5] LPR causes respiratory symptoms such as cough and wheezing [6] and is often associated with head and neck complaints such as dysphonia, globus pharyngis, and dysphagia. [7]
Cancer. Esophagitis, also spelled oesophagitis, is a disease characterized by inflammation of the esophagus. The esophagus is a tube composed of a mucosal lining, and longitudinal and circular smooth muscle fibers. It connects the pharynx to the stomach; swallowed food and liquids normally pass through it.
