“…Short‐term survival rates in horses that had surgery of the small intestine and were allowed to recover from anaesthesia ranged from 68% to 100% in reports published between 2000 and 2017 . Although these results would suggest a considerable improvement over studies from previous decades, many of the more recent studies failed to match the high survival rates reported from one hospital for small intestinal lesions before 1981 .…”

Colic surgery is one of few treatments in which a veterinarian can use a skill to save an animal's life from a deadly disease within a short timeframe. Unfortunately, such success is not achieved without considerable risk for surgical failure, which is responsible for most complications in the immediate post-operative period. The last 50 years have witnessed considerable improvements in colic surgery, although a ranking of the most important ones might not meet with universal agreement. Teamwork plays a critical role in the final outcome, starting and finishing with the referring veterinarian and owner. These individuals are responsible for promptly transferring the horse to a surgical facility and then dealing with aftercare and delayed complications. The surgeon is responsible for the intervening steps, including the decision on the need for surgery, and works with the anaesthesiologist to help a metabolically challenged patient to tolerate surgery and anaesthesia. Although early referral and improved diagnostic procedures can have a positive influence on survival, perceived improvements in surgery and anaesthesia need to be reviewed with some circumspection. Although more rigorous definitions and statistical analyses used in recent studies can invalidate comparisons with older studies, complication rates appear to be on the rise, despite putative improvements in dealing with them. This trend tends to diminish the value of colic surgery through increasing costs, overreliance on post-operative pharmacological management, growing pessimism, high rates of intraoperative euthanasia, and possibly reduced long-term survival. Future efforts should address these concerns, mostly through emphasis on prompt referral, good surgical technique and reducing the cost of colic surgery to an affordable level that saves more lives.

“…Hematological parameters used to evaluate the risk of mortality include anion gap, L‐lactate, ionized calcium, ionized magnesium, creatinine, and glucose 9–16 . Evaluation of peritoneal fluid lactate concentrations and appearance are also suggested to be useful to predict survival of horses with specific types of colic 6,8,17–21 . The advantage of single variable predictors is that they can be rapidly assessed in the course of clinical evaluation and do not require reference to algorithms or complex calculations.…”

Performance of predictive models of survival in horses undergoing emergency exploratory laparotomy for colic

Objective To evaluate previously published predictive survival models in a population of horses undergoing colic surgery in the midwestern United States. Study design Retrospective cohort study; single referral hospital. Animals A total of 260 horses met the inclusion criteria. Methods Medical records of horses undergoing surgical treatment for colic were reviewed. Previously published models were applied to cohort data to predict outcome. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy for prediction of short‐term survival were calculated. Results Single‐variable and multivariable models performed similarly for prediction of survival, with a mean 79% sensitivity (range: 44%–94%), 48% specificity (range: 22%–83%), 63% PPV (range: 56%–72%), 73% NPV (range: 60%–83%), and 64% accuracy (range: 59%–72%). Blood lactate ≤6 mmol/l and the colic severity score (CSS) were highly sensitive for prediction of survival; however, both had poor specificity. Conclusion Single‐variable and multivariable predictive models did not perform as well for prediction of survival in the study cohort compared to original reports, suggesting that population‐specific factors contribute to patient survival. Clinical significance Predictive models of survival developed in one population may be less reliable when used to predict outcome in horses undergoing colic surgery from an independent population. Additional model testing and refinement using data from multiple surgical centers could be considered to improve prediction of outcome for horses undergoing laparotomy for treatment of colic.
