Abstract

Narrow-band imaging (NBI) is a novel optical technique that uses narrow bandwidth filters in a video endoscope system to improve the diagnostic capability of endoscopes in characterizing tissues. It is well known that early identification of neoplasia in the gastrointestinal tract using this technique might make it possible to reduce the suffering of patients caused by loss of function or severe complications after radical surgery. Several reports have introduced this system as a preoperative examination to evaluate the lateral spread of the neoplastic lesions in the oropharynx or hypopharynx. We experienced a case with hypopharyngeal cancer in which we were able to avoid underestimating cancer lesions following insufficient resection using the NBI system. A 62-year-old female underwent partial hypopharyngectomy with the margin estimated by an NBI view coupled with reconstruction of the hypopharynx while preserving the larynx. The resected specimen was cut into serial sections for a detailed pathology examination. The surgical margin seemed to be wide enough and it could be assumed that if possible we should observe these cancers with conventional electroendoscopy and NBI before treatment. Copyright
