Simultaneous Endoscopic Resection of Superficial Cancers of the Hypopharynx and Esophagus: A Case Report.

Diagnosis and treatment of superficial laryngopharyngeal cancers has recently received considerable attention. Here, we present a case of superficial hypopharyngeal cancer and superficial esophageal cancer treated with simultaneous endoscopic laryngopharyngeal surgery (ELPS) and endoscopic submucosal dissection (ESD). The patient was a 67-year-old man. During his follow-up for distal gastrectomy-performed earlier for stomach cancer-upper gastrointestinal endoscopy revealed three primary cancers: a superficial hypopharyngeal cancer, superficial esophageal cancer, and esophagogastric junction cancer. After total resection of the remnant stomach, combined hypopharyngeal ELPS with esophageal ESD was performed. He developed aspiration pneumonia after surgery but recovered and was discharged on the 16th day. Thus, safe and effective endoscopic therapy can be performed even for double superficial cancers of the laryngopharynx and esophagus.
