Use of colonic luminal pressure to predict outcome after surgical treatment of strangulating large colon volvulus in horses.

This study evaluates the connection between colonic luminal pressure (CLP) measurements and the results in horses who have had surgery for large colon volvulus (LCV). The study suggests that the accuracy of predicting the outcome based on CLP measurements is poor, especially after a certain type of surgery (large colon resection and anastomosis (LCRA)).

Research Purpose and Methodology

• The research aims to see if there is a relationship between CLP measurements and the outcome in horses diagnosed with LCV, post their surgical treatment. The treatment could be either a manual correction or a surgical process called LCRA.
• The researchers conducted a retrospective study focused on a total of fifty-seven horses that had been treated for LCV between March 1997 and December 2003.
• Criteria for inclusion in the study included horses with strangulating LCV proximal to the cecocolic ligament, whose CLP measurements had been recorded and who had successfully recovered from anesthesia following their operation.

Research Findings and Analysis

• Out of the 57 total horses evaluated, 27 had undergone manual correction (M) for LCV, while 30 had been treated with LCRA.
• The researchers found that in group M (those treated manually), the sensitivity and specificity of CLP measurements in predicting survival were 0.60 and 0.77 respectively.
• In contrast, for group R (those treated with LCRA), the sensitivity and specificity were 0.50 and 0.54 respectively. The decrease in values indicates a lower accuracy of CLP measurements in predicting post-operative survival for this group.

Conclusions and Recommendations

• The study concluded that the accuracy of using CLP measurements for predicting the outcome of horses post-surgery for large colon volvulus was rather poor, especially following LCRA treatment.
• It advises that CLP measurements, when based on a single hospital population of horses with LCV, should be used cautiously for predicting the outcome in other similar hospital contexts.
• The research endorses the idea that CLP might just be one of multiple variables needed to accurately predict the outcome for horses with strangulating LCV, especially after LCRA. Thus, a broader perspective might be needed for effective prognosis.
