- Occurs in:
- Dogs
- Seen in animals that develop torsion of the stomach; however, they usually die first.
- Horses
- Dogs
Pathogenesis
- Rupture usually occurs along greater curvature.
- While the muscle ruptures, the mucosa does not as it is much more flexible.
- Occasionally stomach ruptures completely.
- Bacteria invade the abdomen, producting peritonitis.
- Horses are acutely sensitive to peritonitis (ruminants are much less so).
- This makes rupture acutely fatal, but animals usually die first from shock.
Note
- Post- mortem rupture of the stomach may be seen in horses that have been dead for a few days.
- This is due to gas accumulation
- Ante-mortem rupture usually has haemorrhage associated with edges of lesion.
