Removal of bronchial foreign body in children by bronchoscopic CO2Cryotherapy / 临床儿科杂志

ABSTRACT

Objective To assess the efficiency and safety of the bronchoscopic CO2cryotherapy to remove bronchial foreign body in children. Methods From Oct 2012 to Dec 2016, 8 cases diagnosed with the presence of bronchial foreign body were undergone the treatment with the bronchoscopic CO2cryotherapy. The clinical data about the efficiency and complication were collected and retrospectively analyzed. Results In the 8 cases, we successfully removed the bronchial foreign bodies without complications. In 2 cases, the foreign bodies were removed successfully, but cryotherapy partially damaged the airway mucosa, causing topical airway obstruction because of the newly developed granulation tissue. No serious adverse reactions or complications were observed after the treatment. Conclusions Removal of bronchial foreign bodies using bronchoscopic CO2 cryotherapy is an easy and effective method which can be used as a supplementary procedure for the bronchoscopic removal of foreign bodies in children's airways.
