Abstract:
OBJECTIVE To investigate the characteristics of hypopharyngeal carcinoma detected by narrow band imaging(NBI)endoscopy and evaluate the value of NBI in the early diagnosis of hypopharyngeal carcinoma. METHODS Between December 2008 and July 2009,a total of 46 consecutive patients with hypopharyngeal squamous cell carcinoma were enrolled in this study. High performance endoscopic system equipped with the white light mode and NBI mode was introduced in the examination of pharynx and larynx. The quality of visualization of morphologies of epithelial capillary and demarcation line of each lesion under NBI view was evaluated in comparison with conventional white light endoscopy. RESULTS Among the 46 patients,a total of 86 lesions were detected. The notable characteristic of hypopharyngeal squamous cell carcinoma is the well demarcated brownish area and scattered brown dots. The NBI laryngoscope could provide better visualization of morphologies of epithelial capillary and demarcation line in superficial carcinoma of hypopharynx than the white light mode(P
