Objective—To evaluate the historical data, signalment, clinical signs, results of laboratory analyses,
treatment, and outcome of horses with small intestinal (SI) volvulus.
Study Design—Retrospective study.
Sample Population—One hundred and fifteen client-owned horses, aged 1 month to 21 years.
Methods—Clinical signs, laboratory data, surgical or necropsy findings, and outcome for horses with
SI volvulus were obtained from medical records, identified by computer search and manual review.
Results—There was no statistical difference in signalment between cases and the hospital population.
Seventy-four percent of horses were 3 years. There were considerable variations in clinical
signs on admission; high heart rate and signs of severe pain were not consistent features. Examination
per rectum identified distended small intestine in only 69% of horses. One hundred horses
had surgery, and small intestine resection was performed in 25. Eighty-four horses were recovered
from surgery, and 67 horses survived to hospital discharge (80% of horses recovered from surgery,
58% of 115 horses). Forty-eight percent that were ultimately discharged had a post-operative
complication and these horses had a longer average stay than horses with no complication (11 days
versus 8.9 days).
Conclusions—We identified 115 horses with primary SI volvulus over a 12-year period. We found
that the population of horses with this lesion was older than has previously been reported and that
the prognosis for post-operative survival to hospital discharge is good (80%). Post-operative complications
were common, and affected approximately half the horses that were ultimately discharged
from the hospital.
Clinical Relevance—This information may aid diagnosis and prognosis and guide decision making
for horses with this condition.
