A novel instrument set for tracheal anastomosis was developed and tested in dogs. While complications like stenosis occurred, the procedure showed potential for effective tracheal repair.

Area of Science:

  • Thoracic Surgery
  • Surgical Innovation
  • Veterinary Medicine

Background:

  • Gastrointestinal and vascular anastomosis techniques have advanced significantly.
  • Tracheal and bronchial anastomosis remain challenging surgical procedures.
  • A new approach is needed to improve tracheal anastomosis outcomes.

Purpose of the Study:

  • To develop and evaluate a novel set of instruments for tracheal anastomosis.
  • To establish operative procedures for end-to-end anastomosis of the canine cervical trachea.

Main Methods:

  • A novel instrument set was created, including forceps, a connecting device, and stapling forceps.
  • End-to-end anastomosis was performed on 23 dogs using the developed instruments.
  • Postoperative monitoring included daily observation, periodic bronchofiberscopy, and necropsy for mortality evaluation.

Main Results:

  • Complications observed included stenosis (8/23), tracheal rupture (3/23), and granulation (4/23).
  • Eight dogs experienced no complications following the procedure.
  • Histological analysis indicated anastomotic healing comparable to traditional hand-suture methods.

Conclusions:

  • The novel instrument set provides a viable method for canine cervical tracheal anastomosis.
  • Further refinement may be necessary to minimize complications such as stenosis and rupture.
  • The findings support the potential of this technique for future clinical application in tracheal surgery.
