Thoracoscopic-assisted lung lobectomy in cat cadavers using a resorbable self-locking ligation device.

Area of Science:

• Veterinary Surgery
• Thoracic Surgery
• Surgical Innovation

Background:

• Thoracoscopic-assisted lung lobectomies are common procedures.
• Effective airway sealing at the hilus is critical to prevent complications.
• Current methods like thoracoabdominal staples may have limitations.

Purpose of the Study:

• To compare the maximum airway pressure sustained by LigaTie and thoracoabdominal (TA) staples.
• To evaluate the efficacy of these devices during thoracoscopic-assisted hilar lung lobectomies.

Main Methods:

• In situ cadaveric study using ten feline cadavers.
• Twenty lung lobectomies were performed with either LigaTie or TA staplers (10 per group).
• Airway pressures were tested up to 40 cmH2O.

Main Results:

• All LigaTie sites sealed effectively without leaking.
• Four of ten TA stapled sites leaked at a mean pressure of 22 cmH2O.
• TA staple leaks occurred when the staple line was >5mm from the hilus.

Conclusions:

• LigaTie consistently sealed airways at the hilus without leaks.
• LigaTie is a potentially effective alternative to TA staples for lung lobectomies in cats and small dogs.
• Further clinical testing is warranted.
