I'd discuss any concerns you have about post op care with your Vet.
From experience, the wound site will need checking at least twice a day for any signs of infection - look for swelling, oozing (serous fluid) redness and if it is warm to touch.
Pain relief is always a good idea, Metacam is the usual analgesia prescribed and you may be given a short course of antibiotics as a precautionary measure against infection.
I always keep my piggies post op on one level with no ramps etc. to avoid straining or jumping - pop hay into a holder rather than a tray etc. if you can so he won't sit in wee/poo. Keep a close eye out for any blood loss too. I always put white vet bed or very light coloured fleece in the pen.
If antibiotics are prescribed, be aware that they can upset piggy tums quickly especially Baytril so a probiotic is always recommended two-three hours after abx.
Monitor food/fluid intake as any surgery can play havoc with appetite and lead to further issues needing hand feeding.
It all sounds very overwhelming but many of us have nursed our babies post op and are able to advise and help you through the initial 'critical' period - Muffin may well be running around as soon as he gets home but better to be prepared.
All paws firmly crossed for your furries...big hugs
