RESUMEN
Foreign body (FB) aspiration is a potentially life-threatening accident in children. Traditionally, rigid bronchoscopy has been the procedure of choice for FB removal, however it may miss distally lodged FBs. We report two pediatric cases with distal impacted FBs that could not be retrieved by rigid bronchoscopy (RB) and were mobilised using Fogarty balloon followed by flexible bronchoscopic cryoextraction. The advantage of a cryoprobe is lower risk of fragmentation of FB that may occur with forceps. Cryoextraction is particularly advantageous for removing water-containing FBs. In both patients, FB was removed more than 2 weeks following aspiration, leading to the formation of granulation tissue around the FB, which considerably hampered the process. Using a laryngeal mask airway to secure the airway, FB removal by flexible bronchoscopy may be a safe and effective technique in skilled hands, especially for FBs impacted in distal airways with granulation tissue where RB fails.
