(117 cards)
What is Achalasia? (Cardiospasm)
An esophageal motility disorder involving the smooth muscle layer of the esophagus, and the lower esophageal sphincter (LES)
What is Achalasia characterized by?
- Incomplete relaxation of LES - It’s increased tone - Lack of peristalsis of esophagus
What is Primary Achalasia?
MC** Characterized by failure of distal esophageal inhibitory neurons - The Auerbach’s plexus (myenteric plexus)
What does the Auerbach’s plexus (or myenteric plexus) provide?
Motor innervation to both layers of the muscular layer, having both para and sympathetic output
What is special about Meissner’s plexus?
It has ONLY parasympathetic fibers and provides secretor innervation to the mucosa nearest the lumen of the gut
What could secondary Achalasia result from?
Cancer of esophagus or upper stomach
What else could Secondary Achalasia result from?
Infection with Protozoa (Trypanosoma Cruzi) which causes destruction of the myenteric plexus of the esophagus with its dilation
Achalasia caused by Tripansoma cruzi is known as _____
***Chaga’s Disease SECONDARY ACHALASIA
What are the signs and symptoms of Achalasia?
- Dysphasia 2. Regurgitation 3. Chest pain 4. Coughing 5. Aspiration of food or liquid
What is “Dysphagia” associated with Achalasia?
Difficulty in swallowing of solid or liquid food
What is “Regurgitation” associated with Achalasia?
Backflow of undigested food
Why would you have chest pain with Achalasia?
BEHIND THE STERNUM With radiation to the neck or armS* (NOT JUST ONE ARM) Can be extremely painful and gets worse AFTER eating
Why would there be “Coughing” with Achalasia ?
Cough when you’re in a HORIZONTAL position especially at night
What will you see on X- Ray with Achalasia?
Use contrast liquid swallowing shows the narrowing of the distal part of esophagus
What is the radiographic sign apparent with Achalasia?
“Bird’s Beak” or “Rat’s Tail” sign** Along with dilation above
How is there a diagnosis of Achalasia?
Upper Endoscopy (Gastroscopy)
What are the 3 complications of Achalasia?
- Aspiration pneumonia or airway obstruction 2. Lower esophageal diverticulum 3. Esophageal Cancer (in 5% of patients)
What do you recommend to patients with Achalasia ?
- Eat slowly - Avoid eating near bed time - Avoid ketchup, citrus, chocolate, caffeine - Physician consultation
What is a Hiatal Hernia of the esophagus?
Protrusion of the upper part of stomach into thorax through the space between the muscular Curran’s of the diaphragm (hiatus)
What are the different forms of Hiatal Hernia?
- Sliding MC* 2. Rolling or Paraesophageal
What happens during a Sliding Hernia?
Where the gastroesophageal junction together with the stomach move above the diaphragm
What type of dilation do you see with a sliding hernia?
Bell Shaped* MC form of hiatal hernia
What is a rolling or paraesophageal hernia?
When a separate portion of the stomach, usually along the greater curvature, enters the thorax through the widening foremen
What is condition can be an etiology of Hiatal Hernia?
Kyphoscoliosis
