Abstract

Background: An open-label, single-arm study was conducted to assess the safety of a cryosurgery unit named CRYO2 for debulking at the site of obstruction or stenosis. Patients and Methods: In order to treat central airway tumor-related stenosis, debulking at the stenotic site of the airway was performed using CRYO2 under general or local anesthesia. The primary endpoint was the incidence of moderate to massive hemorrhage. Results: Incidence of moderate to massive hemorrhage during surgery was 3.8% (1/26) (95% confidence interval(CI)=0.1-19.6%). Technical success was 96.2% (25/26), with a 95% confidence interval of 80.4-99.9%. Conclusion: CRYO2 for debulking at the site of obstruction or stenosis can be performed safely.
