Assessment of videofluoroscopic swallow study findings before and after cricopharyngeal myotomy.

Both symptomatic and objective improvement in swallowing measures occurs after cricopharyngeal myotomy. Pouch remnants and retained barium are seen postoperatively but do not correlate with reported symptoms. Routine follow-up barium studies may be needed to establish a new baseline and allow for comparison if future symptom recurrence occurs.
