IBD confirmed in my boa... what should I be expecting?

[xFenrir]

TLDR; Just trying to get more info and understand where my expectations should be at, since I was under the impression that snakes with IBD had no other option but euthanasia...

A little backstory: in late 2020 my boa (unsure of age, we're guessing she could be anywhere from 12 to 16 at this point) got a lump in front of her vent area which was tested and confirmed to be an infected scent gland. After months of trying to drain it and antibiotics and it shrinking but not getting totally better, we elected to remove it. It turned out to actually have necrosis. Removed it, she healed up beautifully with just a scar from the surgery.

About September this year, after helping her with a torn shed, we noticed part of her upper belly portion seemed "caved in" and so we called the vet. Since she was still acting normal otherwise, they booked us for the earliest appointment a month out and said to watch her and call if anything changed. Vet saw her, thought she might have arthritis and attempted x-rays while un-sedated which were too blurry to use, but she saw some fuzziness that could have possibly been arthritis. Booked her to come back on a surgery day next week so we could sedate her and get clear x-rays. X-rays reveal the fuzziness is a serious infection in her spine, with what seems to be partial bone growth and maybe some spinal fusion (which now seems very likely to some degree). Ordered cultures and blood work and it comes back with obvious inclusions, and we get the diagnosis that she has IBD. I thought the next thing she was going to say was we had to euthanize her, but she said since she's the only reptile we have that since she's still eating and drinking and generally moving around it's worth trying to treat the infection. She's currently on Amikacin for antibiotics (the culture showed the type of infection is responsive to it) and pain meds, both injectable. We also attempted laser therapy today in case it helps with any inflammation or pain, which put her in a feisty mood (not sure if that's good or bad...)

I always thought IBD was an immediate death sentence. I'm more than willing to fight the good fight for her, and my vet hasn't said all hope is lost, but I'm also trying to look up research and there's... not much out there that I can find. They all basically say the same things: pythons with IBD pass quickly, boas it could be weeks or months, or they can recover and become carriers. They could live with IBD but pass from complications due to weakened immune system. Everything says there is no treatment and euthanasia is recommended, but most of this info is from at least a few years ago. Where else can I turn to for information?
