[Successful awake tracheal intubation in the sitting position using the Pentax-AWS Airwayscope in a patient with hypopharyngeal cancer and gastroesophageal regurgitation].

We report the successful awake tracheal intubation in a patient with hypopharyngeal cancer and gastroesophageal regurgitation with the TaperGuard Evac tracheal tube (TaperGuard) and Pentax-AWS Airwayscope (AWS). A 63-year-old man with hypopharyngeal cancer with invasion to the glottis was scheduled for total laryngectomy under general anesthesia. He had undergone thoracic esophagectomy and could not maintain supine position due to severe gastroesophageal regurgitation. To avoid vomiting after induction of anesthesia, we planned awake intubation in the sitting position with the AWS. After topical anesthesia with 8% lidocaine and infusion of fentanyl and continuous dexmedetomidine, the AWS was inserted into his mouth in the sitting position from the cranial side. The AWS allowed visualizing the glottis avoiding the cancer, leading to safe placement of the tracheal tube.
