Flashcards in Esophageal Diverticulum Deck (10):
What is the most common site for esophageal diverticula?
What causes pulsion diverticula to develop?
A motility abnormality found distal to diverticula
Are pulsion or traction forces the most common cause of esophageal diverticula?
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.
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.
What is the best imaging study to evaluate esophageal diverticula?
Barium swallow and video swallow
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.
What conditions contribute to cricopharyngeus muscle dysfunction?
Neurological damage (eg after stroke/trauma), cervical spine injuries after procedures, scarring or fibrosis, and radiation therapy.
What is the preferred (traditional) procedure for Zenker's diverticulum?
Cervical cricopharyngeal myotomy, and diverticulectomy or diverticulopexy
