Historical review spotlights rise of equine minimally invasive surgery: full analysis

A new 2026 review in JAVMA argues that the future of equine minimally invasive soft tissue surgery is best understood through its past. The paper, “Historical perspectives guide advances in equine minimally invasive soft tissue surgery,” describes a field that has moved from niche adoption to broader clinical demand, with laparoscopy and related approaches increasingly used in equine referral practice and training. The authors point to practical gains that have helped drive that shift, including reduced cost and risk tied to general anesthesia and recovery, improved surgical visualization, and faster return to performance.

That trajectory has been building for years. Earlier reviews describe equine laparoscopy as first reported in the 1970s and now standard of care for a number of procedures, including cryptorchidectomy, ovariectomy, nephrosplenic space ablation, standing abdominal exploration, and several reproductive surgeries. More recent summaries from academic and referral centers show how the technique has become embedded in everyday equine surgical decision-making, especially when a standing, sedated approach can avoid the hazards of recumbent anesthesia and recovery in horses.

The new review also connects clinical uptake with professional infrastructure. ACVS has formal fellowship pathways in minimally invasive surgery, including large animal soft tissue, and lists approved training centers for that work. That matters because one of the biggest barriers to wider use of advanced laparoscopy in horses has been the need for specialized equipment, case volume, and surgeon training. The paper’s emphasis on historical perspective appears to reinforce a broader point: progress in equine MIS has depended not just on instruments and optics, but on organized training and standard-setting.

Clinically, the value proposition is familiar but still important. ACVS materials on standing equine laparoscopic ovariectomy say the approach has become a popular alternative because it is minimally invasive, avoids the risk of general anesthesia, improves visualization and access, and decreases convalescence. Purdue’s equine service similarly describes laparoscopy as a way to approach the abdomen with less need for open surgery in selected cases, while cautioning that it is not a universal substitute for traditional abdominal procedures. That nuance is important in equine practice, where case selection, temperament, anatomy, and the underlying disease process still determine whether a minimally invasive option is truly the best one.

Outside the review itself, recent literature suggests the field is still working through its limits as well as its advantages. A 2022 scoping review on complications related to equine laparoscopy concluded that the approach offers improved visibility, diagnostic accuracy, and lower morbidity and hospitalization time, but also noted inconsistent reporting of intraoperative and postoperative complications. In other words, enthusiasm for minimally invasive surgery is real, but so is the need for better outcome definitions, stronger comparative data, and continued refinement of technique. (mdpi.com)

Why it matters: For veterinary professionals, this story is really about maturation of a subspecialty. Equine minimally invasive soft tissue surgery is no longer just a technical add-on at a handful of centers; it is increasingly tied to fellowship-level training, continuing education, and procedure-specific expectations around welfare, recovery time, and return to use. For referral hospitals, that can support investment in equipment and surgeon development. For ambulatory and primary care veterinarians, it may shape when to refer horses for procedures such as cryptorchidectomy, ovariectomy, or selected exploratory and reproductive interventions that could benefit from standing laparoscopy.

The message may also resonate with pet parents and horse-industry stakeholders because the benefits described in the review map closely to practical concerns: fewer anesthesia-related risks in appropriate cases, potentially shorter recovery, and less time away from performance or breeding. At the same time, the literature and referral-center guidance both suggest that minimally invasive does not mean low-skill or low-risk. Adoption depends on training, patient selection, and realistic expectations about what these approaches can and cannot replace. (eurekamag.com)

What to watch: The next phase will likely center on expanded fellowship training, broader dissemination of advanced laparoscopic techniques, and better data on outcomes and complications, especially as surgeons push into newer concepts such as natural orifice transluminal endoscopic surgery and other lower-trauma approaches in horses.
