Flashcards in Esophageal Diverticulum Deck (10):
1

What is the most common site for esophageal diverticula?

Cervical Esophagus

2

What causes pulsion diverticula to develop?

A motility abnormality found distal to diverticula

3

Are pulsion or traction forces the most common cause of esophageal diverticula?

Pulsion

4

What is a Zenker diverticulum?

A pulsion diverticula secondary to a dysfunctional cricopharyngeus muscle - this results in herniation of esophageal mucosa through weak points within the pharyngeal musculature.

5

What is the necessary surgical treatment for Zenker's diverticula?

Esophageal myotomy must be performed, with or without diverticulectomy or diverticulopexy because of the underlying cricopharyngeal muscle dysfunction.

6

What is the best imaging study to evaluate esophageal diverticula?

Barium swallow and video swallow

7

What is the role of manometry in Zenker's diverticulum?

None, however in mid or distal esophageal diverticula, it should be used to assess abnormalities of esophageal motility.

8

What conditions contribute to cricopharyngeus muscle dysfunction?

Neurological damage (eg after stroke/trauma), cervical spine injuries after procedures, scarring or fibrosis, and radiation therapy.

9

What is the preferred (traditional) procedure for Zenker's diverticulum?

Cervical cricopharyngeal myotomy, and diverticulectomy or diverticulopexy

10

How does Zenker diverticulum often present?

Dysphagia, halitosis and regurgitation
