Introduction
Endoscopic laryngopharyngeal surgery (ELPS) is an effective treatment for early-stage oropharyngeal and hypopharyngeal cancers. Since 2007, we have performed ELPS on 14 patients with early-stage cancer who had undergone radiation therapy (salvage ELPS). We discuss the beneficial effects and issues with salvage ELPS compared with those of fresh patients since we experienced some severe complications, such as ruptured pseudoaneurysm with salvage ELPS.

Aim
To our knowledge, the efficacy and safety of ELPS following radiation therapy have not yet been evaluated, and several unknown factors exist. An evaluation was performed for assessing whether ELPS following radiation therapy is safe, similar to findings in fresh cases previously reported by us, and whether this treatment method can be efficacious.

Material and methods
We studied the cases of 14 patients who had undergone salvage ELPS after radiation therapy for head and neck cancer at Akita University Hospital between 2007 and 2018.

Results
The rate of recurrence of head and neck cancer at different sites after salvage ELPS was 48.9% at 2 years. Furthermore, deformation of the pharyngolarynx made it extremely difficult to perform surgery. We also experienced extremely severe complications of ruptured pseudoaneurysms.

Conclusions
If salvage ELPS is performed after radiation therapy, patients should be followed up on an outpatient basis to monitor the onset of subsequent cancers. Complications may become severe; therefore, postoperative management should be performed cautiously. In particular, vulnerable sites, such as the piriform sinus, may not be indicated for surgery. At this stage, the expectation is that patients need to be methodically selected.
