Veterinary Surgery July 2025 – Soft Tissue Part 3: Laser Sphincterotomy, Feline PANS & Lap Chole in Cats

In this Simini Small Animal Surgery Podcast episode, we explore three cutting-edge studies from the July 2025 issue of Veterinary Surgery—each one helping refine high-risk soft tissue interventions through better diagnostics, emerging techniques, and practical survival insights.

We cover:

✅ Miyagi et al. — An ex vivo pilot study demonstrating the feasibility of endoscopic-assisted laser sphincterotomy (EARC) for the intramural bile duct in dogs. They achieved 100% procedural success in 18 cadavers and identified a reliable visual cue to guide incision—offering a safer, minimally invasive future for biliary access.

✅ Otero Balda et al. — A multicenter retrospective study of 59 cats with post-attenuation neurologic signs (PANS) following CPSS surgery. While 78% survived to 30 days, generalized seizures dropped survival to 50%. Propofol use flagged more severe cases but wasn’t directly causal.

✅ Poggi et al. — A 22-cat case series of laparoscopic cholecystectomy—the first published feline series of its kind. The results? 100% completion, 4.5% mortality, and shorter hospital stays versus open surgery—if you choose cases carefully and watch for post-op EHBDO.

Three studies. One message: risk doesn’t rule out innovation—if you plan carefully.
