Gastric Accommodation and Gastroesophageal Reflux

2014-08-27 03:15:35 | BioPortfolio

Summary

Gastroesophageal reflux events generally happen during relaxation of lower esophageal sphincter. This relaxation is a reflex that is triggered by gastric stimuli. The investigators hypothesize that abnormal relaxation of the gastric wall after a meal may lead to reflux events. To test this hypothesis, a study was designed to measure the gastric accommodation in patients undergoing esophageal impedance monitoring.

Description

Gastroesophageal reflux events happen during relaxations of lower esophageal sphincter not related to swallowing, called transient. These transient lower esophageal sphincter relaxations (tLESR) are generally triggered by gastric distension and its physiological purpose is to vent the stomach. The gastric accommodation is a physiological process in which the gastric fundus actively relaxes during a meal in order to accommodate it.

This study is driven by the hypothesis that impairment of the gastric accommodation may facilitate triggering tLESR and, therefore, reflux events. We aim to evaluate the relation between gastric fundic relaxation and the number of gastroesophageal reflux events in children. We also aim to evaluate if there is a relation between the gastric emptying and the number of reflux episodes.

Medical and Biotech [MESH] Definitions

Retrograde bile flow. Reflux of bile can be from the duodenum to the stomach (DUODENOGASTRIC REFLUX); to the esophagus (GASTROESOPHAGEAL REFLUX); or to the PANCREAS.

Back flow of gastric contents to the LARYNGOPHARYNX where it comes in contact with tissues of the upper aerodigestive tract. Laryngopharyngeal reflux is an extraesophageal manifestation of GASTROESOPHAGEAL REFLUX.

The R-isomer of lansoprazole that is used to treat severe GASTROESOPHAGEAL REFLUX DISEASE.

Chronic ESOPHAGITIS characterized by esophageal mucosal EOSINOPHILIA. It is diagnosed when an increase in EOSINOPHILS are present over the entire esophagus. The reflux symptoms fail to respond to PROTON PUMP INHIBITORS treatment, unlike in GASTROESOPHAGEAL REFLUX DISEASE. The symptoms are associated with IgE-mediated hypersensitivity to food or inhalant allergens.

A substituted benzamide used for its prokinetic properties. It is used in the management of gastroesophageal reflux disease, functional dyspepsia, and other disorders associated with impaired gastrointestinal motility. (Martindale The Extra Pharmacopoeia, 31st ed)
