Recurrence following treatment of Zenker's diverticulum (ZD) occurs in
up to 16 per cent of patients. We have reviewed our experience with c
ricopharyngeal myotomy (CM) to determine its safety and efficacy in th
e treatment of recurrent ZD. Eight patients were treated, five with ea
rly recurrence (symptoms persisting or recurring within 6 months of th
eir initial surgery) and three with late recurrence, Most patients wit
h early recurrence did not have an adequate CM as part of their initia
l therapy, suggesting that adequate myotomy is important for early rel
ief of dysphagia. Seven patients underwent CM alone, and one patient u
nderwent CM with diverticulectomy. All patients experienced immediate
relief of their dysphagia, with good to excellent results persisting a
t last follow-up (mean follow-up 53 months). Complications were seen o
nly in the patient who underwent combined myotomy with diverticulectom
y. We have found CM alone to be quite safe and effective in the treatm
ent of recurrent ZD.
