摘      要：AIM:To evaluate the utility of magnified narrow-band imaging(NBI) endoscopy for diagnosing and treating minute pharyngeal ***:Magnified NBI gastrointestinal examinations were performed by the first author.A magnification hood was attached to the tip of the endoscope for quick *** of the examinations were performed under *** NBI examinations were performed for all of the pharyngeal lesions that had noticeable brownish areas under unmagnified NBI observation,and an intrapapillary capillary loop(IPCL) classification was made.A total of 93 consecutive pharyngeal lesions were diagnosed as IPCL type Ⅳ and were suspected to represent ***-two lesions of approximately 1 mm in diameter were biopsied in the clinic,and 17 lesions with larger diameters were resected by endoscopic submucosal dissection(ESD) at the Hiroshima University *** addition to the histological diagnoses,the lesion diameters were microscopically measured in 45 of the 62 *** of the 62 biopsied patients received endoscopic follow ***:Minute pharyngeal lesions were diagnosed in 93 of approximately 3000 patients receiving magnified NBI examinations at the *** the 93 patients with IPCL type Ⅳ lesions,80 were men,and 13 were ***-six were drinkers,and 57 were *** had esophageal ***-one lesions were located on the posterior hypopharyngeal wall,and 72 lesions were located on the posterior oropharyngeal *** 93 lesions were flat and showed similar findings in the magnified and unmagnified NBI *** almost all of the IPCL type Ⅳ lesions showed faint redness when examined under white light,it was difficult to diagnose the lesions using only this technique because the contrast was weaker than that achieved in the NBI *** the 93 lesions,only 3 had diameters greater than 2.1 ***-two lesions of approximately 1 mm were biopsied in the clinic,whereas 17 larger lesions were tre
