Summary
# Editorial Summary: Equine surgical colic: risk factors for postoperative complications Postoperative complications following colic surgery represent a significant clinical challenge, extending hospitalisation periods and increasing both patient morbidity and treatment costs. French and colleagues analysed data to identify risk factors for six common complications—jugular thrombosis, ileus, re-laparotomy, wound suppuration, incisional herniation and recurrent colic—using multivariable statistical modelling. Elevated heart rate (>60 bpm) and increased packed cell volume at admission emerged as strong predictors of jugular thrombosis and ileus, findings the authors interpret as indicators of endotoxaemia severity; notably, horses with epiploic foramen entrapment faced over four times the risk of re-laparotomy, whilst those recovering from large colon torsion (>360°) demonstrated a 3.1-fold increased risk of subsequent colic. The practical implication is clear: early referral before severe endotoxaemic shock develops may substantially reduce complication rates, and recognition of case-specific risk factors enables more accurate postoperative prognostication and potentially targeted preventative strategies during recovery management. These findings underscore the importance of assessing admission cardiovascular parameters as prognostic indicators and tailoring post-operative monitoring protocols accordingly.

Practical Takeaways
- •Early referral of colic cases before severe endotoxaemic shock develops may reduce postoperative complication rates, particularly when admission heart rate and PCV are elevated
- •Horses with epiploic foramen entrapment and those developing postoperative ileus warrant intensive monitoring as they carry substantially higher re-laparotomy risk
- •Aggressive management of cardiovascular parameters perioperatively and careful wound care may reduce incisional herniation risk in recovery
Key Findings
- •Jugular thrombosis risk increased significantly with heart rate >60 beats/min and elevated packed cell volume (PCV) at admission
- •Postoperative ileus risk increased with higher PCV at admission and was significantly higher in horses recovering from pedunculated lipoma obstruction
- •Incisional herniation was strongly associated with wound suppuration and increasing heart rate at admission
- •Horses with epiploic foramen entrapment were >4 times more likely to require re-laparotomy; large colon torsion (>360°) and prior re-laparotomy increased postoperative colic risk 3.1-fold and 3.4-fold respectively
