1

Esophagus

Muscular tube that conveys food from pharynx to stomach

2

Two Layers of Muscle in the Esophagus

Inner circular muscle
Outer longitudinal muscle

3

How does food pass through the esophagus?

Perstalsis

4

What are the two types of movement?

Perstaltic
Segmental

5

What kind of movement is peristaltic?

Moves food forward

6

What kind of movement is segmental?

Mixing

7

3 locations where dysphagia can occur?

In the lumen
In the wall
Outside the wall

8

Dysphagia in the Lumen

Tumor

9

Dysphagia in the Wall

Achalasia
Tumor of the esophagus
GERD
Plummer Vinson syndrome
Scleroderma
Chagas' disease

10

Define Achalasia

Neurological disturbance of the dilation of the LES

11

What is Plummer Vinson Syndrome?

Iron deficiency anemia

12

Define Scleroderma

Normal collagen replaced with tissue with no contractility

13

Dysphagia Outside the Wall

Pressure of enlarged lymph nodes
Thoracic aortic aneurysm
Bronchial carcinoma
Retrosternal goiter

14

Dysphagia due to Neuromuscular Disorders

Myasthenia gravis
Stroke

15

What is the responsibility of the circular muscles of the esophagus?

Propulsion down the esophagus

16

3 Parts of the Esophageal Anatomy

UES
Esophageal body
LES

17

UES

Closes
Relaxes

18

LES

Has base line tone
Closed
Semi-closed

19

Which muscles are used for peristalsis?

Longitudinal muscle
Circular muscle

20

Electrode Sleeve Catheter

Measures pressure changes in the esophagus

21

Normal Phases of Swallowing

Voluntary
Involuntary
Between swallows

22

Voluntary Swallowing

Bolus is voluntarily moved into the pharynx

23

Involuntary Swallowing

UES relaxation
Peristalsis
LES relaxation

24

Between Swallowing

UES prevents air entering esophagus
UES prevents esophagopharyngeal reflux
LES prevents gastroesophageal reflux
Peristaltic & non-peristaltic contractions
Capacity for retrograde movement and decompression

25

Types of Esophageal Disorders

Motility
Anatomic & Structural
Reflux
Infectious
Neoplastic
Perforation
Burns
Bleeding

26

Presentation of Esophageal Reflux

Pain
Obstruction (dysphagia)
Bleeding

27

Upper Esophageal Motility Disorders

Oropharyngeal dysphagia
Pharyngoesophageal neuromuscular disorders
UES dysfunction/HTN

28

Pharyngoesophageal Neuromuscular Disorders

Stroke
Parkinson's
Poliomyelitis
ALS
MS
DM
Myasthenia graves
Dermatomyositis & polymyositis

29

Example of UES Dysfunction/HTN

Lou Gehrig's Disease

30

Define Achalasia

Incomplete relaxation of lower sphincter during swallowing leading to functional obstruction and proximal dilatation
