Summary
Outcomes for surgically treated dogs with large intestinal volvulus are excellent, with 100% survival to discharge. However, dogs with small intestinal volvulus have a poor prognosis, with only 16% survival to discharge.
Area of Science:
- Veterinary Surgery
- Canine Gastroenterology
Background:
- Intestinal volvulus is a surgical emergency in dogs.
- Outcomes vary significantly based on the affected intestinal segment.
Purpose of the Study:
- To compare surgical outcomes for canine large versus small intestinal volvulus.
- Evaluate survival rates and long-term prognosis after surgical correction.
Main Methods:
- Retrospective study of 15 dogs undergoing abdominal exploratory for intestinal volvulus (October 2009 - February 2014).
- Comparison of outcomes between dogs with large intestinal volvulus (n=9) and small intestinal volvulus (n=6).
Main Results:
- 100% survival to discharge for large intestinal volvulus (9/9 dogs).
- 16% survival to discharge for small intestinal volvulus (1/6 dogs).
- High mortality and euthanasia rates in small intestinal volvulus due to bowel necrosis.
Conclusions:
- Surgical correction of large intestinal volvulus in dogs yields excellent outcomes.
- Small intestinal volvulus carries a poor prognosis, even with surgical intervention.
- Prompt diagnosis and surgical intervention are critical for canine intestinal volvulus.
