Cryotherapy or Cryosurgery relies on repeated freeze-thaw cycles to destroy tissue and tumor. Cryotherapy has also been used to remove foreign bodies and blood clots in the airways. Freezing the object to the probe tip allows retrieval of the foreign body along with removal of the cryoprobe and bronchoscope unit from the airways. We applied the same technique to remove large endotracheal protruding necrotic tumors for histopathology study and for relief from dyspnea, stridor and hemoptysis.
We report 22 flexible endobronchial Cryosurgery sessions in 12 patients (6 men and 5 women with primary or metastatic endobronchial lung cancer and 1 patient with endobronchial actinomycosis).We used the cryoprobe foreign body technique in 6 out of 11 patients for diagnosis and immediate debulting of the tumor in the same session, since substantial part of the tumor was removed ( up to 5 cm length).
Symptoms, as hemoptysis, stridor and dyspnea subsided the same or the next day. In the other 5 patients ,the cryoprobe modality was used only for palliative reasons, not for diagnostic ones. A second or third bronchoscopy with or without cryotherapy was repeated by the same brochoscopist. All the procedures were recorded and pictures of the immediate results are presented.
The Flexible Endobrochial Cryoprobe procedure is a safe , low cost, immediately effective (not only late) modality for endobronchial and endotracheal obstructive necrotic polypoid tumors, for diagnostic histopathology study (quite large specimen ) and relief from dyspnea and hemoptysis at the same time (one session ).
Cryoprobe procedure can be used ,even in small Hospitals instead of the high cost laser technique.
