In addition to use of a laser, argon plasma coagulation, electrocautery, or coring with a rigid bronchoscope, tumor debulking with a flexible cryoprobe is used for therapeutic bronchoscopy with an immediate effect for endobronchial pathologies. We performed this analysis to determine the usefulness, efficacy, and safety of the flexible cryorecanalization in a large population under routine conditions.


We identified 225 bronchoscopic interventions that were done as cryorecanalization with a flexible cryoprobe. All patients had symptomatic airway stenosis. We determined the endoscopic success rate and safety (bleeding and perforation) of the procedure.
