Hello, I live in Seoul currently. If it were my hedgehog, I would not let that doctor do surgery on him if he has no experience with it. Is this an ordinary vet or an exotic vet? I have had regular vets in Korea think my hedgehog was constipated when she was not (took her to a exotic vet after and he said she was not). I would 100% not trust an ordinary vet with your hedgehog. For something this serious, I would venture to Busan or Seoul (where I know there are good exotic vets). It might take a lot of time and money, but I think it is worth it if you want to put your hedgehog's life in good hands. If you want, you can tell me where you live and I can try to help you find an exotic vet. Your best bet would probably be Seoul, though. The place I take my girl to is in the Gangnam area (Acris animal medical center) and I have seen even racoons and meerkats in that place. They were also super gentle and knowledgeable about my hedgehog.
