  abstract     = {{Background : 
Intussusception and mesenteric torsions are the most frequent causes of colic requiring surgery 
in cattle. Whether survival chances of these conditions differ in the same institute is currently 
unknown. Also, clinical and laboratory factors available upon admission that can differentiate 
between intussusception and torsion are unknown. Therefore, the objective of this study was to 
determine mortality and factors associated with mortality in cattle with colic and to identify 
factors that distinguish between torsion and intussusception pre-surgery.

Methods : 
A retrospective cohort study was conducted based on the medical records of the Large Animal 
Internal Medicine clinic, Ghent University. Records between January 1, 2020 and December 31, 
2023. Inclusion criteria were cattle with colic signs. Clinical examination, blood gas analysis and 
hospitalization records were used to complete the dataset. Survival analysis was used to 
determine factors associated with mortality. Logistic regression to identify factors that can 
differentiate torsion from intussusception upon admission. 

Results : 
The dataset included 177 cases whereof 95 mesenteric torsions, 42 intussusceptions and 40 
other causes of colic and surgery in cattle. The mortality until discharge was 50.5%, 38.1% and 
65.0% in torsion, intussusception and other causes, respectively. There was no significant 
difference in mortality between dairy and beef cattle nor sex. Multivariable analysis showed that 
breathing frequency >58/minute (P=.008; OR 1.88; CI 1.2-3.0), lactate >5.925 mmol/L (P=.003; 
OR=1.9; CI 1.3-3.0) and calcium <1.095 mmol/L (P=.003; OR 1.6; CI 1.0-2.4) resulted in an 
increased mortality risk with sensitivity, specificity and accuracy of 65.6%, 32.9% and 49.7 
respectively. There was no significant difference in prevalence of torsion and intussusception 
between dairy and beef cattle. A multivariable model to predict intussusception and differentiate 
from torsion included age at entry (P=<.161; OR=1.001; CI 1.000-1.002), heart rate <114 beats 
per minute (P=<.028; OR=3.1; CI 1.1-8.2), pH >7.395 (P=<.017; OR=3.4; CI 1.3-9.4) and chloride 
<91.5 mmol/L (P=<.004; OR=4.3; CI 1.6-11.5). Sensitivity, specificity and accuracy of this model 
were 56.4%, 92.6% and 82.0%, respectively. 

Conclusions : 
In the present study, mortality was numerically higher in cases of mesenteric torsion compared 
to intussusception. Alkalemia, hypochloremia and age show potential for differentiation of these 
conditions upon arrival which can be used for decision making regarding surgery.}},
