Esophagus
• 25 cm long
• tubular
• Propulsion of bolus into the stomach
• Interferes with acid content regurgitation
• Cervical, middle, supracardial part
• 3 physiological narowings
• Epiphrenic ampulle
• 2 sphincters
![Page 3: Diseases of the upper GI tract, epigastric pain](https://reader030.vdocuments.us/reader030/viewer/2022012723/61b5151f4f9cda6a0c26f575/html5/thumbnails/3.jpg)
Symptoms of esophageal diseases
• Epigastric pyrosis, heartburn
• Regurgitation
• Dysphagia, odynophiagia
• Chest pain (non-cardiac)
Examination methods
• Laboratory parameters
• Barium swallow
• Upper GI endoscopy
• Examinations of motility - manometry
• Impedance

GERD – complex motility disorder
• main patogenetical factor: dysphunction of LES + decreased esophagealclearence + prolonged gastric emptying
• Agressive factors:
• Gastric acid + pepsin
• Duodenogastric reflux:
• Conj., deconj. bile acids, tripsin
