I don't think the correlation is well known - that abstract I think is a bit obscure, and I've never seen it referred to anywhere else.
I don't think that there is anything you could have done. My boy bloated and torsioned, and did it on and off for the week before, before it went into a full scale emergency. Off course, I only know that in hindsight. I think dogs destined to bloat or torsion will typically do it - it's not within our control in most cases.
The point at which *might* have made a difference is if the vet would have tacked the stomach when the spleen was removed. And that's on the medical community, not at all on you. I knew about that abstract, and I probably would forget to bring it up to the vet before a spleen removal, and even then, that's not on me, that's on the medical community, not the dog owner.
I understand guilt when losing a dog very well. We just have to find a way to forgive ourselves. We expect superhuman perceptive abilities because we so want our dogs to still be here and we want to think that they could have been saved.
The most important thing you can try to do, is to figure out how to relieve that guilt. Do pass the abstract on to your vet, so your boy's legacy will be to help those after him.
