Tracheal reconstruction with autogenous jejunal microsurgical transfer

Area of Science:

• Veterinary Surgery
• Regenerative Medicine
• Surgical Innovation

Background:

• Tracheal defects from strictures, tracheomalacia, or neoplasms pose significant reconstructive challenges.
• Current reconstructive methods for tracheal defects can be complex and may yield suboptimal outcomes.

Purpose of the Study:

• To evaluate the efficacy of microsurgical free tissue transfer of autogenous jejunal segments for reconstructing cervical tracheal defects in dogs.

Main Methods:

• Surgical creation of tracheal defects in 6 dogs.
• Reconstruction using microsurgical free tissue transfer of autogenous jejunal segments.
• Assessment of healing via bronchoscopy, gross pathology, direct measurements, and microscopy.

Main Results:

• Primary healing was achieved in all subjects without significant air leakage or infection.
• Bronchoscopy revealed minimal secretions and no substantial tracheal narrowing.
• Pathological examination confirmed no tracheal disruption or infection, with maintained tracheal lumen dimensions.

Conclusions:

• Microsurgical free tissue transfer of jejunal segments is a viable and effective method for reconstructing cervical tracheal defects in dogs.
• This technique promotes excellent healing and preserves tracheal lumen integrity.
• Autogenous jejunal segments offer a promising solution for complex tracheal reconstruction challenges.
