Peroral endoscopic tumor resection of recurrent hypopharyngeal fibrovascular polyp.

Background and Aims: Fibrovascular polyps (FVPs) are rare benign submucosal tumors of the pharynx and cervical esophagus that can cause dysphagia and airway obstruction. We report the successful endoscopic resection of a recurrent FVP in the hypopharynx using peroral endoscopic tumor resection techniques in combination with pharyngeal endoscopic treatment strategies. A 56-year-old woman presented with a recurrent FVP in the right arytenoid region after an incomplete resection. Because of tumor growth and worsening dysphagia, we opted to perform the endoscopic resection after thorough evaluation. Methods: The procedure was performed with the patient under general anesthesia. Intra- and postoperative airway management was secured with temporary percutaneous cricothyrotomy. Laryngeal expansion was performed with a curved rigid laryngoscope to enhance visualization. Endoscopic resection was performed with a minimal mucosal incision, followed by enucleation of the tumor, and closure of the mucosa. En bloc enucleation of the tumor was achieved without damaging its surface using string-clip traction. Results: The patient was discharged on postoperative day 6 without adverse events. Pathologic examination confirmed complete resection of the FVP. Conclusions: Endoscopic resection using combined peroral endoscopic tumor resection techniques and pharyngeal endoscopic treatment strategies offers a safe and minimally invasive treatment option for hypopharyngeal FVPs.
