Q: How can I decide whether to put my horse through a big operation, like colic surgery?

A: This is a big decision that it is best to make in advance of your horse becoming unwell so that you know the decisions you are going to make ahead of the stressful situation. Making the decision in advance will also speed up the process, as any delay can reduce the chances of a successful recovery.

Colic surgery is a big undertaking and may not be the best option in every case. Many horses go on from surgery to have successful competitive careers, but some never return to their previous level of fitness, and others have complications after surgery that can be life-threatening.

It is also worth bearing in mind that the horse will require a general anaesthetic, which in itself has a number of risks, such as cardiac arrest or tissue damage. Overweight or older horses can be at higher risk of difficulties following general anaesthetic, so making sure your horse is in otherwise good health beforehand is key to a positive outcome.

Older horses without any health concerns do equally well as younger horses following colic surgery so age is less of an issue. However, very overweight horses have a higher risk of problems under general anaesthesia, as well as with healing of the wound post operatively. Similarly, horses with conditions such as arthritis may struggle to get up after the anaesthesia. They will also become stiff during the post-operative box rest, which is usually at least four weeks in the case of colic surgery.

The mental state of your horse is also worth considering. Recovery from surgery is usually slow, and anxious horses can find the process unbearable. In particular, some horses will struggle to cope with the box rest, and their anxiety may precipitate another colic episode. Whilst most horses will ultimately adapt, getting your horse prepared in advance to equip him to handle stressful situations will be a significant advantage if ever he does require surgery.
