Conclusion: Laryngotracheal separation (LTS) can prevent aspiration pneumonia, improve the respiratory condition, and offer the possibility of home care for neurologically impaired children.
Objectives: This study aimed to evaluate the effectiveness of LTS in neurologically impaired pediatric patients from the viewpoint of postoperative success of pneumonia prevention, improvement in the respiratory condition, and postoperative success rate of home-based care.
Methods: The medical records of 21 children who underwent LTS at an academic medical center from September 2004 to March 2013 were retrospectively investigated. Pre- and postoperative data, including the frequency of pneumonia treatment, the frequency of sputum suctioning, the respiratory condition, the nutrition method, and the outcome after LTS were assessed. We also used the scoring system for patients with severe motor and intellectual disabilities, medical care dependent group (SMID-MCDG) in Japan for evaluating the usefulness of LTS.
Results: The frequency of pneumonia treatment and that of suctioning decreased considerably after LTS. Furthermore, the respiratory condition improved at a rate of 63.19%. The SMID-MCDG score significantly reduced after LTS. No significant complications were observed and two-thirds of the patients were successfully discharged for home care after the procedure.
