Physical exam for dysphagia

Types of tests for dysphagia
- Barium swallow
- Endoscopy
Barium swallow capabilities for dysphagia

Endoscopy capabilities for dysphagia

Describe diffuse esophageal spasm via barium swallow
spastic “Corkscrew appearance”

Describe eosinophilc esophagitis via barium swallow
corrugated appearance from furrows that form from the scarring from eosinophilic infiltration

What is depicted by barium swallow?

Diffuse Esophageal Spasm

What is depicted by barium swallow?

Eosinophilic Esophagitis

Describe esophagitis via endoscopy
breaks in mucosa (represents esophageal injury

What is depicted via endoscopy?

Achalasia

What is depicted via endoscopy?

Adeno Carcinoma

What is depicted via endoscopy?

Candida

What is depicted via endoscopy?

Esophagitis

What is depicted via endoscopy?

Schatzki ring

What is depicted via endoscopy?

Peptic stricture

What is depicted via endoscopy?

Diffuse Esophageal spasm

What is depicted via endoscopy?

Eosinophilic Esophagitis

Describe peptic stricture via endoscopy
scarred down
needs to be dilated or stretched out

Describe Schatzski ring via endoscopy
doesnt expand any further
can be broken up by biopsy cuts to open it up

Describe adenocarcinoma via endoscopy
lumen is narrowed by neoplasm

Describe Candida via endoscopy
growth of fungus

Describe eosinophilic esophagitis via endoscopy
corrugated rings or could be linear corrugation

Describe achalasia via endoscopy
the sphincter is super tight

Describe Diffuse eosphageal spasm via endoscopy
“corkscrew” spasming

Approach to dysphagia

What is a high-resolution manometry catheter?
basically an EKG of esophagus

High-resolution manometry catheter data

Normal swallow under High-resolution manometry catheter

Describe Achalasia by barium swallow

HRM AKA
High-resolution manometry catheter
HRM of type II Achalasia
Failure of LES to relax

Subtypes of achalasia

Upper endoscopy of Achalasia

Describe Type I Achalasia HRM
Absent peristalsis
No peristaltic waves, no movement

Describe Type II Achalasia HRM
Panesophageal pressurizations occur after a swallow but could keep going

Describe Type III Achalasia HRM
Hypercontraction but not a productive peristaltic spasm
food still gets trapped and patient still feels bolus stuck
Why does achalasia occur?
- Loss of myenteric neurons such as by immune-mediated neuronal death
- Imbalance between excitatory and inhibitory forces
Describe achalasia by loss of myenteric neurons

Describe achalasia by excitatory/inhibitory imbalance

Achalasia type I causation
loss of myenteric nerves
Achalasia type II causation
Loss of myenteric neurons
Achalasia type III causation
Excitatory/inhibitory force imbalance
Pharmacological therapy of Achalasia
(botox is kind of the go to)

Surgical interventions of achalasia
- Pneumatic dilation (balloon)
- Heller Myotomy (cut the circular muscle fibers)

Response rates of achalasia treatments

POEM for achalasia

POEM outcomes

Achalasia means?
“Failure to relax”
The predominant feature of achalasia
poorly relaxing LES
Symptoms of Achalasia
- Dysphagia
- Regurgitation
- Heatburn
- CP
- Cough
- Choking
- Aspiration pneumonia
- Weight loss
Achalasia Manometric abnormalities
- Abnormal LES residual pressure
- No normal peristalsis
Is achalasia ever cured?
What treatments are there?
Never cured and treatment is aimed at reducing the pressure across the LES
- Pneumatic dilation
- Heller Myotomy
- POEM
- Botox, CCB, nitrates
What is pseudoachalasia?

Dysphagia workup pathway

What is the patient’s diagnosis?

Pseudoachalasia
Is this achalasia


EGD pseudoachalasia
