Aims: In order to observe the pharyngoesophageal junction, the trumpet maneuver with trans-nasal endoscopy was used. Its efficacy is reported here. Material and Methods: A 71-year-old man who underwent esophagectomy in esophageal cancer 2 years ago was admitted to our hospital with primary pharyngeal cancer. The type of upper endoscope used was EG-580NW (FUJI Film, Tokyo, Japan). The endoscope is a trans-nasal endoscope that can provide high quality endoscopic images. The pharyngeal cancer located at right lateral wall which was previously detected could be observed easily. We asked the patient to blow hard and puff his cheeks with his mouth closed. When inspecting the hypopharynx and the orifice of the esophagus, we told the patient that we would start the trumpet maneuver. Results: After the trumpet maneuver, the pharyngeal mucosa was stretched out. Another primary lesion was observed at the posterior wall of the hypopharynx near the pharyngoesophageal junction. This technique provided a much better view of the lesion than had been possible with trans-oral endoscopy，allowing us to remove the biopsy specimen without sedation. Conclusion: In conclusion, the trumpet maneuver using trans-nasal endoscopy is a useful technique for precise inspection before treatments for patients who have already detected the lesions.
