Upper and lower human gastrointestinal tract. The esophagus (American English) or oesophagus (British English, see spelling differences; both / iː ˈ s ɒ f ə ɡ ə s, ɪ-/; [1] pl.: (o)esophagi or (o)esophaguses), colloquially known also as the food pipe, food tube, or gullet, is an organ in vertebrates through which food passes, aided by peristaltic contractions, from the pharynx to the ...
In an effort to improve diagnostic accuracy of testing, a catheter with two pH sensors has been used to measure the degree of esophageal acid exposure in both distal and proximal esophagus. The ideal location for pH measurement to confirm the diagnosis of the laryngopharyngeal reflux is the pharynx and new studies have focused on the ...
The gastrointestinal tract (GI tract, digestive tract, alimentary canal) is the tract or passageway of the digestive system that leads from the mouth to the anus. The GI tract contains all the major organs of the digestive system, in humans and other animals, including the esophagus, stomach, and intestines. Food taken in through the mouth is ...
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 ...
Esophageal cancer also presents with progressive mechanical dysphagia. Patients usually come with rapidly progressive dysphagia first with solids then with liquids, weight loss (> 10 kg), and anorexia (loss of appetite). Esophageal cancer usually affects the elderly. Esophageal cancers can be either squamous cell carcinoma or adenocarcinoma.
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.
Esophageal rupture, in Boerhaave syndrome, is thought to be the result of a sudden rise in internal esophageal pressure produced during vomiting, as a result of neuromuscular incoordination causing failure of the cricopharyngeus muscle (a sphincter within the pharynx) to relax. As the intra-oesophageal pressure increases, the bolus within the ...
Endoscopy with biopsies of the esophagus has a 100% sensitivity and 96% specificity for diagnosing eosinophilic esophagitis. [8] Biopsy specimens from both the proximal/mid and distal esophagus should be obtained regardless of the gross appearance of the mucosa. Specimens should also be obtained from areas revealing endoscopic abnormalities.
