Cough reflex sensitivity does not correlate with the esophageal sensitivity to acid in patients with gastroesophageal reflux disease.

The sensitization of cough reflex observed in patients with gastroesophageal reflux disease (GERD) is attributed to activation of vagal C-fibers innervating the esophagus by acid, while the heartburn ...

Usefulness of the "continuous insufflation method" for observing the cervical esophagus.

The cervical esophagus is the short part of the esophagus between the lower border of the cricoid cartilage and the thoracic inlet (suprasternal notch), and is ~18 cm from the incisor teeth [1]. Diffi...

Circumferential distribution and clinical characteristics of esophageal cancer in lower esophagus: differences related to histological subtype.

Esophageal adenocarcinoma (EAC) is frequently found on the right-anterior wall of the distal esophagus in short-segment Barrett's esophagus (SSBE) patients. However, the endoscopic characteristics of ...

Venous Malformation of the Esophagus.

Venous malformations are an extremely infrequent condition in the gastrointestinal tract, particularly in the esophagus. We herein report a rare case of an adult with an asymptomatic mass located in t...

Treatment Outcomes of Endoscopic Submucosal Dissection for Adenocarcinoma Originating from Long-Segment Barrett's Esophagus versus Short-Segment Barrett's Esophagus.

In recent years, effective outcomes of endoscopic submucosal dissection (ESD) for esophagogastric junction cancer including short-segment Barrett's esophagus (SSBE) cancer have been reported. However,...

Medical and Biotech [MESH] Definitions

A motility disorder of the ESOPHAGUS in which the LOWER ESOPHAGEAL SPHINCTER (near the CARDIA) fails to relax resulting in functional obstruction of the esophagus, and DYSPHAGIA. Achalasia is characterized by a grossly contorted and dilated esophagus (megaesophagus).

Misunderstanding among individuals, frequently research subjects, of scientific methods such as randomization and placebo controls.

A condition with damage to the lining of the lower ESOPHAGUS resulting from chronic acid reflux (ESOPHAGITIS, REFLUX). Through the process of metaplasia, the squamous cells are replaced by a columnar epithelium with cells resembling those of the INTESTINE or the salmon-pink mucosa of the STOMACH. Barrett's columnar epithelium is a marker for severe reflux and precursor to ADENOCARCINOMA of the esophagus.

Abnormal passage communicating with the ESOPHAGUS. The most common type is TRACHEOESOPHAGEAL FISTULA between the esophagus and the TRACHEA.

A DIVERTICULUM at the upper end of the ESOPHAGUS through the cricopharyngeal muscle at the junction of the PHARYNX and the esophagus.
