Diseases of the upper GI tract,epigastric pain

Dr. Hajnal Székely

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

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

Congenital diseases

1/3000-4000 ; Genetical factors + intrauterin enviromental factors

50%-associated with other developmental alterations (spine, airways, kidneys)

Atresia

Tracheooesophageal fistula

Congenital stenosis

Doubled esophagus

Esophageal ring

Esophageal diverticula

• Aquired, occur predominantly in adulthood

• Classified according to: site of occurence:

• Hypopharyngeal – Zenker

• Epiphrenic

• Middle third

Esophageal diverticulaclassified according to mechanism of formation

According to wall thickness: true or false

Types: sliding - paraoesophageal-mixed

GERD – Montreal classification

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

Esophagectomy:

• 3-10% mortality

• 45% morbidity

• Patients operative risk

• Focality of dyspl.

• Local endosc. +

• Surgical expertise

• EMR

• ESD

• RFA

Eosinophilic esophagitis - EE

• allergen-driven inflammation of the esophagus;

• P:30/100.000

• Young (21-31y)

• male patients (65-70%)

• 40-50% atopic diseases: asthma, food allergy,

• rhinitis all., rhinoconj., dermatitis

• Sy.: children – nausea, abd. pain, eating dist.

• Young – dysphagia, food impaction

• Elderly- + regurgitation, heartburn

Dg.based on histological examination of upper and lower esoph. biopsies (6) after initial treatment with PPPIs for 6–8 weeks.

Th.:Identification of the underlying food / airborne allergen –directs dietary advice.six-food elimination diet - can be tried if specific allergens cannot be identified.

Pharmacologic th: topical corticosteroids and leukotriene antagonistsEsophageal dilation - associated strictures, rings Safe- perforation rate of less than 1% effective - dysphagia improving for up to 1–2 years in over 90%

• Inability of LES relaxation-

• dysphagia for both solids and liquids.
