'''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.'''
<br />
<FlashCard questions="3">
|q1=What abnormalities can be seen?
|a1=
*All the large (5 mm diameter) BIPS, and most of the small (1.5 mm diameter) BIPS are still in the stomach. This suggests there is delayed gastric emptying. Although gastric emptying times are very variable in normal cats, small BIPS will usually completely empty from the stomach within 14 hours (often much quicker) and large BIPS should at least start to empty by this time.
*In addition to the abnormal retention of BIPS, the stomach body and antrum are gas-filled and dilated. This can be seen with pyloric stenosis and other conditions interfering with gastric emptying, and can also be seen with aerophagia (e.g. secondary to dyspnoea). However, this cat was not dyspnoeic, and there is no abnormal air in the intestines.
|l1=
|q2=What diagnosis does this suggest and what treatment options should be considered?
|a2=
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.<br><br>
No treatment is universally successful for these cases.
*Dietary manipulation may help: feeding a low fat diet and feeding liquid or semi-liquid foods may encourage more rapid gastric emptying.
*Prokinetic drugs such as metoclopramide (metoclopramine), cisapride, and erythromycin may help in some individuals.
*Pyloromyotomy has also been reported to be helpful in some of these cats. <br><br>
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.
