Comparison of pharyngeal stenosis between hypopharyngeal patients undergoing primary versus salvage laryngopharyngectomy

Abstract

Objective: To survey the risk factors of pharyngeal stenosis after laryngopharyngectomy in patients with advanced hypopharyngeal cancers.

Study design: Case series with chart review.

Setting: Tertiary medical center.

Subjects and methods: Pharyngeal stenosis rates and risk factors were compared between two groups of laryngopharyngectomy patients: a group that underwent concurrent chemoradiation therapy followed by surgical salvage, and a surgery initiated group with adjuvant chemoradiation.

Results: Of 160 patients, 25 developed pharyngeal stenosis, which was diagnosed by barium esophagography with a pooling of barium contrast above the neopharyngeal inlet. These patients required nasogastric tube feeding or gastrostomy feeding because an oral liquid diet could not meet their nutritional needs. Primary closure and old age were risk factors for pharyngeal stenosis. Pharyngeal stenosis did not affect survival in patients with advanced hypopharyngeal cancer who underwent laryngopharyngectomy.

Conclusion: Primary closure reconstruction is discouraged in patients over the age of 65 years.
