A 2-year-old Siamese cat presented with persistent vomiting of partially digested food several hours after feeding. The VD abdominal radiograph was taken 16 hours after the administration of BIPS.

| What diagnosis does this suggest and what treatment options should be considered? | These changes are typical of ‘pyloric stenosis’. This is a well recognized congenital problem in Siamese cats, although there is no apparent true ‘stenosis’, but rather a functional motility problem resulting in poor gastric emptying in affected cats.
As there is usually no physical obstruction, this should probably be reserved for those cats where medical therapy fails. Pyloromyotomy allows more rapid gastric emptying, but as with the other treatments, the response varies considerably between individuals. |
