Novel Technique for Fixing Tracheal Stents.

Area of Science:

• Pulmonology
• Gastroenterology
• Otolaryngology

Background:

• Airway obstructions, benign or malignant, often necessitate endoscopic stenting post-dilatation or debulking.
• Straight stents are susceptible to migration in the trachea and main bronchus, posing significant risks.
• Existing subglottic stent fixation methods have limitations.

Purpose of the Study:

• To describe a novel stent fixation technique for the upper airway.
• To evaluate the feasibility of the "inside-to-outside" fixation method.

Main Methods:

• The study reports on the use of the Lichtenberger needle carrier for stent fixation.
• The novel "inside-to-outside" technique was applied in two consecutive patients.

Main Results:

• The "inside-to-outside" stent fixation was successfully applied in two patients.
• This technique addresses the challenge of stent migration in the upper airway.

Conclusions:

• The "inside-to-outside" stent fixation using the Lichtenberger needle carrier is a viable new method.
• This technique shows potential for improving stent stability in endoscopic airway management.
