Clinical- Dysphagia Flashcards
Define “dysphagia”
difficulty swallowing due to malfunctioning oropharyngeal or esophageal transport of food
What are the 3 main causes of dysphagia?
- oropharyngeal- bad transfer of a food bolus from the oropharynx to the esophagus
- mechanical- anatomically compromised esophageal lumen
- motor- motility disorder
Why might solid food cause dysphagia but liquid food not cause dysphagia?
mechanical obstruction
What might be the cause if there is dysphagia with both solid and liquid food?
Neuromuscular disorder
This is the first test that should be done in the evaluation of dysphagia.
Esophagogastrodueodenoscopy (EGD)
This is the faulty transfer of a food bolus from the oropharynx into the esophagus.
Oropharyngeal dysphagia
Amyloidosis, dermatomyositis, hyper/othryroidism, MG, and myopathies are classified as what causitive type of oropharyngeal dysphagia?
structural abnormalities
ALS, CVA’s, Huntingtons, MS, parkinsons and tetanus are classified as what causitive type of oropharyngeal dysphagia?
Neurological disorders
Cervical osteophytes, cricopharyngeal dysfxn, goiters, lymphadenopathy and zenker diverticulum are classified as what causitive type of oropharyngeal dysphagia?
Muscular disorders
This is the failure of the esophagus to relax due to degeneration of the Auerback ganglion cells in the LES.
Achalasia
What is the clinical presenstation of achalasia?
years of dysphagia to both solids and liquids, may vomit upundigested food, NO HEARTBURN cuz LES is always contracted
What shows on CXR for achalasia?
air-fluid level within the esophagus in advanced cases
What shows on barium esophagography for achalasia?
dilated esophagus with a beak-like tapering at the LES
What is the triad of conditions in achalasia?
- incomplete relaxation of the LES
- hypterensive LES
- aperistalsis in the esophageal body
Why must u do a EGD to rule out cancer in achalasia?
Cuz cancer could be infiltrating near the esphogaastric jxn and look the same way on radiographs
What is the bug that produces a neurotoxin that destroys the myenteric plexus, and produces achalasia?
Trypanosoma cruzi (Chagas)
This autoimmune condition has secondary involvement with the esophagus, and presents as dysphagia with both solids and liquids and heartburn.
Scleroderma
Break down the CREST acronym for scleroderma
Calcinosis Raynauds Esophageal dysfunction Sclerodactyly Telangiectasias
What will a barium study show for sclerodermal involvement of the esophagus?
rigid esophagus with widely patent LES, aperistalsis of the esophagus and decreased tone of the LES
This condition presents as chest pain, intermittent dysphagia with solids or liquids, and can be aggravated by stress. Barium swallow shows a corkscrew esophagus.
Diffuse esophageal spasm
This is the condition when the mere is mechanical compromise of the esophageal lumen to a diameter <12mm
Mechanical dysphagia
What is the cause of peptic strictures?
prolonged GERD
Where is the most common site of peptic strictures?
it’s a short narrowing of the distal esophagus immediately at or above the esophogastric jxn
What are the 2 main causes of alkaline strictures?
- post-gastrectomy
2. Inducing vomiting after lye ingestion
