In this episode of the Simini Equine Surgery Podcast, we explore the soft tissue research from the April 2026 issue (Issue 3) of Veterinary Surgery, where two studies emphasize that successful surgery extends well beyond the operating room. Together, they demonstrate how better postoperative interpretation and systematic quality improvement can dramatically improve patient outcomes.
One study redefines how surgeons should interpret peritoneal fluid following exploratory laparotomy, while the second shows how simple protocol changes across an entire hospital can nearly eliminate surgical site infections after equine abdominal surgery.
In this episode:
✅ Granello et al. performed a prospective cohort study evaluating postoperative peritoneal fluid changes in 26 horses undergoing exploratory laparotomy for naturally occurring gastrointestinal disease. Serial abdominocentesis performed at 24, 72, and 168 hours demonstrated that although systemic lactate normalized within 24 hours, peritoneal lactate, total protein, and nucleated cell counts remained markedly elevated for up to seven days, regardless of whether the original lesion was strangulating or non-strangulating. These findings indicate that postoperative surgical manipulation itself produces a prolonged inflammatory response within the peritoneal cavity, making serial trends far more valuable than single measurements when deciding whether a horse requires repeat surgical intervention.
✅ López-Cruz et al. evaluated the impact of a comprehensive hospital-wide quality improvement initiative after postoperative surgical site infection (SSI) rates following exploratory celiotomy unexpectedly increased to 29%. Using a structured root-cause analysis (fishbone diagram), the team identified multiple opportunities for process improvement, including separate personnel for sheath and abdominal preparation, two-step skin preparation with detergent followed by chlorhexidine, single-use clipper blades, standardized closure protocols, and application of medical-grade Manuka honey to the linea alba. Following implementation, SSI rates fell dramatically from 29% to just 2.3%, overall wound complications declined to 6.8%, and no horses required euthanasia because of postoperative surgical site complications. The study highlights how meticulous protocol refinement and team consistency can transform surgical outcomes without requiring expensive new technology.
Together, these studies reinforce a powerful lesson in equine soft tissue surgery: excellent outcomes depend not only on performing surgery well, but also on interpreting recovery appropriately and continually improving every step of the perioperative process.
