Veterinary Surgery October 2025 – Soft Tissue Part 2: Feline Clip Closures & Barbed Suture Speed

In this Simini Small Animal Surgery Podcast episode, we highlight two studies from the October 2025 issue of Veterinary Surgery—each focused on refining thoracic soft tissue closure techniques, particularly in space-limited or high-risk scenarios.

We cover:

✅ Ritson et al. — An ex vivo feline study comparing bronchial stump closure methods in hilar lung lobectomy using linear staplers, pre-tied ligature loops (PLLs), and double shank titanium clips (DS clips). All three performed equivalently—even under 40 cm H₂O airway pressure, but the DS clips and PLLs offered major advantages in working space, maneuverability, and minimally invasive access, especially in cats under 4 kg.

✅ You et al. — An ex vivo canine study evaluating a knotless barbed suture system for total lung lobectomy versus traditional sutures and staplers. At normal and supraphysiologic pressures, the barbed suture was equally secure, and 3.4 minutes faster on average than hand suturing. For small patients, tight spaces, or VATS, this may offer both mechanical and procedural benefits.
