To evaluate the efficacy of endoscopic resection tracheoplasty (ERT) for treating post-tracheotomy stomal stenosis caused by inward collapse of tracheal ring remnants.
Prospective observational study.
Between 2007 and 2012, we treated 40 patients with “lambdoid” tracheal deformity with a two-staged minimally invasive procedure undertaken using suspension microtracheoscopy and high-frequency jet ventilation. The first procedure entailed CO2 laser photoablation of collapsed tracheal rings and dilatation. The second procedure, performed 6 to 8 weeks later, involved ablation of residual structural obstruction, removal of granulation tissue, and intralesional corticosteroid injection. Perioperative patient and lesion characteristics and results of treatment were assessed.
There were 22 males and 18 females, and mean age at first treatment was 59 years. There were 17 cases of scarring at the postero-lateral tracheal groove (trachealis blunting), and 22 patients had age-adjusted Charlson comorbidity scores greater than 4. All patients without trachealis blunting were successfully managed endoscopically, with only one patient requiring one additional endoscopic treatment. Seven patients with trachealis blunting needed additional treatment, and four patients had tracheal resection (P = 0.013). All patients were decannulated, and 75% of patients achieved good dyspnea outcomes. Patients with low morbidities were significantly more likely to achieve good dyspnea outcomes (P < 0.027). There were no treatment-related worsenings of voice or swallowing.
ERT is an effective minimally invasive treatment for intubation-related lambdoid tracheal stenosis. It achieves a successful outcome while avoiding the risks associated with open surgery. We recommend its more widespread use for treating patients with this condition.
