Can Recurrence of Hamartomas be Prevented?

General anesthesia was administered by an intravenous anesthesia technique. Patients were intubated with a rigid bronchoscope. Debulking procedures were performed by mechanical tumor resection (MTR) using the tip of the rigid bronchoscope, rigid pliers or argon plasma coagulation assisted MTR or cryorecanalization or electrocautery - snare probe. An innovation of our study was that cryotherapy was performed in the regions where the lesions originated after debulking
