Recurred Post-intubation Tracheal Stenosis Treated with Bronchoscopic Cryotherapy

Area of Science:

• Pulmonology
• Otolaryngology
• Interventional Bronchoscopy

Background:

• Post-intubation tracheal stenosis (PITS) is a significant complication following mechanical ventilation.
• Current treatments include surgery and endoscopic interventions, but efficacy varies.
• The role of cryotherapy in managing PITS remains largely unvalidated.

Observation:

• A case of recurrent, web-like fibrous post-intubation tracheal stenosis is presented.
• The patient had previously undergone surgical treatment for the stenosis.
• Bronchoscopic cryotherapy was employed as a treatment modality.

Findings:

• Cryotherapy demonstrated significant efficacy in treating the web-like fibrous tracheal stenosis.
• Successful treatment with cryotherapy avoided the need for further surgical intervention.
• This case highlights the potential effectiveness of cryotherapy in specific PITS cases.

Implications:

• Cryotherapy presents a viable alternative or potentially primary treatment option for select cases of post-intubation tracheal stenosis.
• This approach may offer a less invasive option compared to repeat surgeries.
• Further research is warranted to establish the broader efficacy and indications for cryotherapy in PITS management.
