Experience of Endoscopic Treatment of Tracheal Granulation by KTP Laser Incision

Abstract

Four cases are presented who, after prolonged indwelling cannulation followed by tracheostomy, developed severe tracheal granulation. It is very difficult with forceps to remove tracheal granulation. An operation was performed by endoscopic KTP laser to vaporise the granulation until a lumen was established down to the tracheostomy site under general anesthesia. After KTP laser surgery we sedated the patient to avoid bronchospasm and used an artificial respirator for 4 to 12 days in the ICU. A KTP laser is indicated when the granulation is too hard to cut by forceps and granulation exist in a very narrow trachea of a child.
