[Application of argon beam coagulator under electronic bronchoscope in the management of pediatric glottic and subglottic diseases].

OBJECTIVE: To summarize clinical experience of application of argon knife under electronic bronchoscope in the management of pediatric glottic and subglottic diseases.

METHOD: Reports in the literature were reviewed. Outcome and prognosis of 4 cases with pediatric glottic and subglottic diseases managed with argon beam coagulator technique in Shanghai children's Medical Center since 2011 were retrospectively analyzed.

RESULT: Granulation tissue hyperplasia in 3 cases with subglottic lesions did not recur after surgery. Scarring or stenosis were not found in the airway. Intubation of the trachea and tube of tracheotomy was pulled out successfully in all cases, restoring normal breathing. No lesion recurrence was found in 1 case with squamous cell moderate atypical hyperplasia one month after the surgery.

CONCLUSION: Electronic bronchoscope has advantages of clear image, fine and soft lens body, optional bending, angle conversion, accurate positioning. And the argon knife with small head diameter can pass the pediatric supraglottic. It can be manipulated precisely with short operation time and no damage to surrounding normal tissues. Its worth in popularization and application of management for with glottic and subglottie disease in pediatric patients.
