 note = {The patient was a 44-year-old woman with a tracheal stent in whom general anesthesia was performed or insertion of a continuous ambulatory peritoneal dialysis catheter. She had experienced cardiac arrest 2 years before due to hyperkalemia caused by diabetic nephropathy. After success of cardiac resuscitation, she was tracheal-intubated and mechanical ventilation was performed for 11 days. However, she subsequently suffered serious dyspnea due to advanced granuloma of the trachea following remove of endotracheal tube. Tracheotomy was performed at 1 month after extubation and a tracheal stent was inserted.
 On this case, general anesthesia was induced with propofol and maintained with 2 L/min oxygen, 2 L/min nitrous oxide and 1.5% sevoflurane 
 As airtight could be kept with a slitless laryngeal mask airway（LMA）, respiratory management proceeded smoothly during anesthesia.
 The reason of choice of slitless LMA instead of endotracheal tube is as follows.
 A slit disturbances an emergence tracheal intubation and bronchoscopy through the LMA.
 The space between the vocal chords and the upper end of stent（approximately 1 cm）was too small to intubate an endotracheal tube. As if endotracheal intubation were performed under these circumstances, the tip of the endotracheal tube remains in the stent.
 In addition, performing endotracheal intubation would have risked distal movement of the stent and difficulty with extubation due to compatibility affinity between the material properties of the stent and the endotracheal tube.},
