Veterinary Surgery May 2025 – Soft Tissue Part 3: Lymph Node Risk & Liver MIS Feasibility

In this Simini Small Animal Surgery Podcast episode, we close out the May 2025 soft tissue series with two studies that refine your surgical mindset—from lymph node staging to complex liver resections.

We cover:

✅ Mattioli et al. — A large retrospective review of 201 peripheral lymphadenectomies in dogs. The findings? Overall complication rates were low—but mandibular and retropharyngeal nodes carried higher risks, especially when surgical time exceeded 21.5 minutes.

✅ Oramas et al. — A cadaver feasibility study using a novel positioning and access strategy for laparoscopic right lateral liver lobectomy. With 100% completion across all cadavers, the approach shows promise even in larger dogs.

Whether you’re refining your approach to surgical oncology or reassessing what’s feasible in MIS liver work, this episode gives you data-driven clarity and practical tips.
