Zenker diverticulum

An older patient has regurgitation of undigested food, halitosis, dysphagia and recurrent aspiration. A contrast swallow shows a posterior pharyngoesophageal pouch. What is the best treatment principle?

CHOOSE ONE ANSWER

Best of five

  1. A. Pouch excision alone without myotomy
  2. B. Proton-pump inhibitor as definitive treatment
  3. C. Total oesophagectomy
  4. D. Treat the cricopharyngeal dysfunction, usually with endoscopic or open myotomy plus pouch management
  5. E. Swallow therapy alone for a large symptomatic pouch
ANSWER AND REASONING

D. Treat the cricopharyngeal dysfunction, usually with endoscopic or open myotomy plus pouch management

The pouch results from outflow resistance at the upper oesophageal sphincter. Diverticulectomy without myotomy risks recurrence; approach depends on anatomy, size and fitness.

Why every option is right or wrong

A. Pouch excision alone without myotomy: This leaves the functional obstruction.

B. Proton-pump inhibitor as definitive treatment: Reflux therapy does not correct the pouch.

C. Total oesophagectomy: This is grossly disproportionate.

D. Treat the cricopharyngeal dysfunction, usually with endoscopic or open myotomy plus pouch management: The pouch results from outflow resistance at the upper oesophageal sphincter. Diverticulectomy without myotomy risks recurrence; approach depends on anatomy, size and fitness.

E. Swallow therapy alone for a large symptomatic pouch: Compensation does not remove retained food and aspiration risk.

What if the scenario changed?

If the pouch were tiny and symptoms mild in a frail patient, conservative management might be reasonable.
