[Morbidly obese patient with a huge ovarian tumor who was intubated while awake using airway scope in lateral decubitus position].

A morbidly obese woman with a huge ovarian tumor was scheduled to undergo tumor resection under general anesthesia. Under slight sedation with midazolam and fentanyl, a tracheal tube was inserted smoothly using Pentax-AWS Airway Scope, and general anesthesia was thereafter maintained by sevoflurane. To avoid circulatory collapse and reexpansion pulmonary edema, the content of the huge ovarian tumor was aspirated through a small drainage tube to reduce volume and weight of the tumor. Then resection of the ovarian tumor and abdominal wall tissue was performed in supine position. Periooperative course was uneventful.
