Esophageal Disease Flashcards
What is dysphagia
trouble Swallowing
What are differential causes of Dyshpagia
achalasia, Diffuse Esophageal Spasm, Scleroderma, Carcinoma, Peptic stricture, Lower esophageal ring, Zenker diverticulum (Halitosis), Muscular dystrophy, Myasthenia gravis, Stroke
What is odynophagia
Painful Swallowing
What are the different causes of Odynopgaia
iron, Vitamin C, Tetracycline, Bisphosphonates, Radiation, CMV, Herpes, Candida, Caustic damage, Eosinophilic esophagitis, quinidine
What is Achalasia
failure of LES (lower esophageal sphincter) and smooth muscle fiber to relax.
What are the causes of Achalasia
It is due to the loss of auerback plexus ( provides motor innervation to both laters of the muscular layer).
How do you diagnose Achalasia
to diagnose, you can do the Barium Swallow ( patient swallow a barium solution and you observe the flow of the fluid through the esophagus), Manometry (measures the contractions of the esophagus)
What is Diffuse Esophageal Spasm
Normal movement but lack of nitric oxide (needed to relax)
How do you diagnose Diffuse Esophageal Spasm
Dx through Barium tortuous esophagus and through manometry,high intensity.
What si Scleroderma
Skin fibrosis- peristalsis and loss of LES tone
What are the characteristics of Scleroderma
it is characterized by the harding of the skin due to lymphocytes. it can affect internal organs.
What causes Scleroderma
due to Vasculitis ( inflammation of blood vessels)
What does CREST stand for
calcinosus, Raynaud phenomenon, esophageal dysfunction, sclerodactyl and telangiectasia)
What are rings and webs and what is associated with it?
Webs are (Upper thin membranes located in the amide or upper esophagus). Plummer Vinson Syndrome
What is Plummer Vinson Syndrome
Plummer Vinson( rare disease that is characterized by difficulty swallow, iron deficiency, glossitis, cheilosis and webs. - risk of hypopharangeal cancer. initial Barium.
