Harry- 18months -2years(rescue piggie).
Before I start these are approx timing as it was a wee while ago now.
Neutered and cleared by vet 3-4 weeks later.
Rescued by me at approx 6 weeks post op and found two infected neutering wounds/ small lumpy swelling. He went back to the vet that did the op for the rescue and prescribed baytirl for 10days, for a second time( not sure why, clearly they didnt stop the iinfection in the first place) Wounds healed, again given all clear.
Approx 1month later lump appeared, decided enough was enough and took him to my own cavvy savvy vet. He was booked in for an another operation to remove the lump diagnosed as an absess for the Monday after a late week appointment.
Monday my vet called to say the stitch was the root of the problem and the absess was attached to the bladder lining and couldnt be removed like a pocketed tumour so to speak. He did some fancy knife work and piggie came home with very open wound exposing the remaining absess lining that couldnt be removed. 2/3rds was sucessfully removed.
14 days later with intensive hospital care, syringe feeding, gut stimulant and antibiotics he was given the all clear.
5months later no reoccurance and one happy little piggy with wifeys.
I believe that the reason for the absess was lack of the proper care post op. Bedded on wood shavings, not cleaned out often enoug or checked regularly for infection. As with me he healed wonderfully with an open wound and very very quiickly.
I dread to think what would have happended to Harry if I hadnt rescued him and discovered his re-opened infecetd wounds.
There are photo's of his original wounds and his op wounds and his general recovery in the below threads:
