Persistent foreign body sensation and pharyngeal pain due to retention of staples: an interesting sequelae of endoscopic stapling procedure.

The surgical treatment of a pharyngeal pouch with endoscopic stapling diverticulotomy is a relatively new concept. Long-term results and complications are yet to be fully studied. We describe a patient who developed persistent pharyngeal pain and foreign body sensation due to retention of a clump of staples at the cricopharyngeal sphincter. This complication has not been reported before. This case highlights the need for repeat endoscopy rather than a barium swallow X-ray if the patients are symptomatic after stapling procedures.
