 At TMDU, from August 1996 to May 2021, a total of 710 superficial pharyngeal cancers in 437 patients were treated with EMR(endoscopic mucosal resection)or ESD(endoscopic submucosal dissection)and ELPS(endoscopic laryngopharyngeal surgery). Since 2009, we have been performing ELPS in collaboration with head and neck surgeons.

 Superficial cancers of ≤4cm, without muscle layer or cartilage infiltration, and without lymph node metastasis are treated at our institution. It is important to focus on aspiration pneumonia in patients with a history of head and neck cancer and postoperative cases of esophageal cancer. Areas that are difficult to treat include the base of the tongue, epiglottis valley, and orifice of the esophagus. Gripping forceps with strong gripping force are used, and a transnasal endoscope is used to obtain a good field of view. It is necessary to focus on infection and rebleeding in salvage cases after radiation therapy. Steroids are useful to prevent severe stenosis in cases of infiltration from the hypopharynx to the orifice of the esophagus.
