Prolapse of the omentum from the scrotal wound:
- Warrants euthanasia because of the poor prognosis

- Can occur months to years after castration
- A and D
- Can be managed by emasculation of the prolapsed tissue in simple cases but may require sx correction thru an inguinal approach
Schirrous cord:

-
Postcastration peritonitis
- Is considered septic when nucleated cell counts of the abdominal fluid exceed 10,000 cells/ul
- Is more likely to result from the open technique of castration
- Is usually inflammatory and self limiting, but sepsis should be suspected if degenerative neuts and phagocytized bacti are evident on cytologic studies

- A and B
Is usually inflammatory and self limiting, but sepsis should be suspected if degenerative neuts and phagocytized bacti are evident on cytologic studies
