A review of patients who had surgery for Zenker's diverticulum in our
institution in recent years was conducted. A comparison of inversion v
ersus excision of the sac shows that inversion carries lower morbidity
and more rapid rehabilitation of swallowing than does excision. Inver
sion (plus cricopharyngeal myotomy) is to be preferred for diverticula
that are neither too large to invert nor too longstanding to risk lea
ving subclinical carcinoma behind in the wall of the diverticulum.
