title: [A Case of Esophageal Polyp Regurgitated into the Pharynx at the Induction of General Anesthesia].
abstract: We report the case of a mass in the pharynx found at the induction of general anesthesia that vanished postoperatively. A 46-year-old man underwent abdominal surgery. After the induction of general anesthesia, there was a mass occupying his pharynx and we could see neither the vocal cords nor the epiglottis using a Macintosh laryngoscope. Airwayscope (AWS) enabled us to successfully intubate the trachea. On postoperative examination, there was no mass on his pharynx. Imaging studies of the esophagus revealed a polyp suspected as being a fibrovascular polyp (FVP) arising from the upper esophagus. Three months later, excision of the polyp was planned. Awake intubation with AWS was planned so that if the polyp was regurgitated, he could swallow it Intubation was uneventful without regurgitation of the polyp. At the beginning of surgery, the polyp was not found in the pharynx, but was easily regurgitated by air supplied by the endoscope. FVPs are rare benign esophageal tumors and most originate from the cervical esophagus. If a polyp is regurgitated, obstruction of the airway may occur, and asphyxiation and sudden death have been reported. The fatal complication of airway obstruction requires anesthesiologists to be aware of FVP.
