Pharyngeal pouch endoscopic stapling - are post-operative barium swallow radiographs of any value?

Posterior pharyngeal pouch endoscopic stapling has gained increasing popularity among otolaryngologists especially in elderly patients. Post-operative barium swallow appearances can create confusion with the appearance of persistent pouches. We describe our experience in 10 patients, three of whom had external excision with cricopharyngeal myotomy and the remaining seven had endoscopic stapling approach. All three patients who had external excision showed no residual pouch whereas all seven patients who had endoscopic techniques performed showed some residual pouch. We were unsuccessful in our attempt to correlate post-operative symptoms with radiological appearance. Attempts by other radiologists at identifying pre- and post-operative barium swallow radiographs in patients who had endoscopic stapling of pharyngeal pouch were unsuccessful. We conclude that post-operative barium swallow radiography plays no role in determining the success of endoscopic stapling of pharyngeal pouch.
