Abstract
For the treatment of a large number of superficial multiple pharyngeal cancers, treatment options that also take into consideration laryngeal function and quality of life after treatment are desired. We report on two-stage transoral excision of simultaneous multiple pharyngeal superficial cancers arising in the bilateral piriform recess. The case was a 70-year-old man with a history of alcoholic cirrhosis. Course of treatment: Partial pharyngectomy from the broader right-side tumor was performed. Two months later, the left tumor was resected. In all cases, local injection of triamcinolone acetonide （TA） was performed after excision, and no postoperative pharyngeal stenosis was observed. Results: The thickness of the tumor was 150μm on the right side and 1,200μm on the left side. Evaluation of tumor blood vessels according to preoperative esophagus superficial esophagus enlargement endoscopic classification, Type B1 on the right side and Type B2 on the left side were considered to be useful for estimation of tumor invasion depth.
