Palliation of postintubation tracheal stenosis using insulation-tipped diathermic knife 2: a case report

Objective: To report the first case of using the insulation-tipped diathermic knife 2 [IT knife-2] for the treatment of postintubation tracheal stenosis

---

Clinical Presentation and Intervention: A 71-year-old female patient with a history of endotracheal intubation 3 years earlier presented with throat discomfort, gross wheezing and dyspnea. Chest imaging and bronchoscopy demonstrated a strand-like tracheal stenosis in the upper trachea. The IT knife-2 was used to treat the patient and the lesion was palliated without complication

---

Conclusion: This case was successfully treated with the IT knife-2 and thus implies a potential usefulness of the IT knife-2 as a new modality for bronchoscopic intervention
