Application of multimodal combined surgical strategy in children with intractable laryngeal airway obstruction

Abstract

Objective:To explore the selection of surgical methods and intraoperative strategies for the treatment of children with intractable laryngeal airway obstruction, and to provide new options for the diagnosis and treatment of children with intractable laryngeal airway obstruction. Methods:The clinical data of 12 children with intractable laryngeal airway obstruction treated by our team from January 2005 to December 2021 were retrospective analyzed. All the children were treated with minimally invasive surgery under rigid bronchoscope or suspension laryngoscope combined with electronic endoscope. The surgical methods included laryngeal microsurgery, plasma ablation, balloon dilatation, drug-eluting stents, laser ablation, endoscopic snare, etc. The patients were followed up after operation. Results:All patients completed the operation under general anesthesia, and there were no intraoperative or postoperative complications. Except for one patient with bilateral vocal cord paralysis who failed to extubation due to restenosis, the others were successfully extubated after operation. Among them, 9 cases of benign space-occupying obstruction were followed up for 5-60 months without recurrence, and 2 cases of malignant tumor-induced obstruction were followed up for 24 months（acinar cell carcinoma） and 36 months（mucoepidermoid carcinoma） without recurrence. Conclusion:Endoscopic multi-operation is effective for children with intractable obstruction. Compared with traditional thoracotomy, endoscopic multi-operation strategies has the advantages of less trauma, faster and safer. For different sizes, locations and pathological types of obstruction, different surgical equipment and methods should be combined.
