[Tracheal resection and reconstruction for tracheal stenosis]

Area of Science:

• Thoracic Surgery
• Surgical Oncology
• Laryngology

Background:

• Tracheal stenosis presents a significant surgical challenge, with causes including congenital abnormalities, post-intubation injury, and malignancy invasion.
• Surgical resection and reconstruction are often necessary for managing severe tracheal stenosis.
• This study focuses on the surgical technique for circumferential tracheal resection and anastomosis.

Observation:

• Five patients with tracheal stenosis (congenital, post-intubation, or cancer-related) underwent surgical intervention.
• All patients required circumferential tracheal resection involving 3-6 tracheal rings.
• End-to-end anastomosis was performed using absorbable sutures (4-0 or 5-0).

Findings:

• The surgical procedure, involving circumferential tracheal resection and end-to-end anastomosis, resulted in no anastomotic complications in any of the five patients.
• Specific technical considerations, including precise dissection, recurrent nerve preservation, use of traction sutures, and postoperative neck positioning, were highlighted.
• The number of resected tracheal rings varied from 3 to 6, indicating adaptability of the technique.

Implications:

• The described surgical technique for tracheal resection and anastomosis is safe and effective for treating diverse causes of tracheal stenosis.
• Careful adherence to technical points, such as nerve preservation and tensionless suturing, is crucial for minimizing complications.
• This approach offers a viable reconstructive option for patients with challenging tracheal pathologies.
