 Recent advances in endoscopic procedures, such as magnifing endoscopy and the NBI(narrow band imaging)system have enabled precise observation of the oropharynx and the hypopharynx. We developed ELPS(endoscopic laryngo-pharyngeal surgery)as endoscopic treatment for superficial carcinoma of the larynx and the pharynx. One hundred and sixty-eight patients who had superficial carcinoma of the oropharynx and the hypopharynx were treated in Kawasaki Municipal Hospital from January 2000 to August 2009. Cervical lymph-node metastasis occurred in 5 patients and lung metastasis occurred in 1 patient. 4 patients died of hypopharyngeal carcinoma, and 28 patients died of other diseases. The overall survival rate at 3 years was 80.2%, and cause-specific survival rate at 3 years was 96.6%. The important factors for predicting lymph node metastasis and distant metastasis are Type 0-I or Type 0-III and angiolymphatic invasion.
