The value of target biopsy using narrow band imaging endoscopy for diagnosis of laryngeal carcinoma / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To estimate the clinical significance of target biopsy in clinical diagnosis, and accurate pathologic specimen acquisition of laryngeal lesion by using narrow band imaging (NBI) endoscopy.@*METHOD@#A total of 156 cases of patients with laryngeal lesions were collected from the department of Otolaryngology Head and Neck Surgery of Tianjin Union Medical Center from Aug 2012 to Dec 2014. All patients were randomly divided into regular biopsy group and NBI target biopsy group. Image data were recorded and the patients' samples were biopsied. The pathologic diagnosis was used to evaluate the accuracy of regular biopsy and target biopsy.@*RESULT@#Based on the pathologic diagnosis, the correct accurate pathologic specimen acquisition rates in NBI target pathology group at stage 0 (Tis), stage I and stage II laryngeal cancer diagnosis compliance rate were higher than those in regular biopsy group, stage 0 (Tis) (χ² = 22.00, P < 0.05), stage I (χ² = 8.33, P < 0.05) and stage II (χ² = 4.55, P < 0.05).@*CONCLUSION@#NBI endoscopy plays an important role in the clinical diagnosis and accurate pathologic specimen acquisition of laryngeal carcinoma and can be a regular means to detect laryngeal lesions in clinical.
