Experimental: EUS-FNA for RPLN in NPC patients
Fine needle aspiration guided by EUS in retropharyngeal lymph node in suspicious recurrent naspharyngeal carcinoma.
Procedure: EUS-FNA for RPLN in NPC patients
An EUS probe was introduced to nasopharynx and the retropharyngeal space (RPS) were scanned. The suspicious recurrent RPLN, which was characterized as (1) roughly round and homogeneously hypo-echoic lesion in RPS; (2) located anterior to the carotid sheath which contained the internal carotid artery (ICA) and the internal jugular vein (IJV). Subsequently, guiding by EUS, a dedicated 22G needle was used to puncture into the enlarged RPLN, then the aspiration was conducted The entire EUS-FNA procedure was repeated at least three times till the satisfied strip tissue was obtained. The obtained tissue samples were sent for pathologic detection and the supernatant fluid was for thinprep cytologic test (TCT).
