Factors for prognostic use in equine obstructive small intestinal disease.

The research article evaluates the prognostic factors in equine obstructive small intestinal disease. A study of twenty horses was carried out to understand the factors which could predict the outcome, especially focusing on peritoneal fluid protein concentration and intraluminal hydrostatic pressure.

Introduction and Methodology

• The study was carried out on twenty horses suffering from small intestinal obstructions and requiring surgery.
• The population was divided into two groups evenly: group 1 (10 horses that survived the condition) and group 2 (10 horses that died).
• The horses were further categorized based on the type of intestinal obstruction: simple obstruction and strangulation obstruction.
• Several values and conditions were measured and analysed including intraluminal hydrostatic pressure, peritoneal fluid protein concentration, PCV, total serum protein content, WBC count, anion gap, duration of colic before admission, and the severity of intestinal mucosal lesions.

Findings

• Around 80% of the horses in group 1 had a simple obstruction, while 70% of the horses in group 2 suffered from a strangulation obstruction.
• Mean intraluminal hydrostatic pressure was markedly different between group 1 and group 2 with group 1 (6.3 cm H2O) much lower compared to group 2 (15 cm H2O).
• The level of peritoneal fluid protein concentration was significantly lower in group 1 (2.8 mg/dl) as compared to group 2 (5.4 mg/dl).
• Severe mucosal lesions were more prevalent in horses of group 2 based on the histologic evaluations.

Conclusion

• The researchers noticed no significant difference for PCV, total serum protein content, WBC count, anion gap, and the duration of colic before admission between the groups.
• However, the peritoneal fluid protein concentration and intraluminal hydrostatic pressure significantly differed between the two groups.
• The research concludes that peritoneal fluid protein concentration and intraluminal hydrostatic pressure in small intestinal obstruction may be used as additional aids in diagnosing and predicting the prognosis of equine obstructive small intestinal disease.
