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

In recent times, the diagnosis and treatment of superficial laryngopharyngeal cancers has been receiving a lot of attention. Here, we present a case of superficial hypopharyngeal cancer and superficial esophageal cancer for which endoscopic laryngo-pharyngeal surgery (ELPS) and endoscopic submucosal dissection (ESD) were performed simultaneously. The patient was a 67-year-old male. During his follow-up for distal gastrectomy performed earlier for stomach cancer, an upper gastrointestinal endoscopy revealed three primary cancers: superficial hypopharyngeal cancer, superficial esophageal cancer, and esophagogastric junction cancer. Total resection of the remnant stomach was performed followed by hypopharyngeal ELPS combined with esophageal ESD. He developed aspiration pneumonia after the surgery; however, he 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.
