Well, even with a bunch of facts at our hands - the tummy is a weird place. If she had noodles - the mouth and pancreas should've released amylase to start the breakdown of that carb, so, one would think you'd see some breakdown. But, if she was bloated from yesterday and had some slowing of her system - it makes me wonder if she's having some delayed emptying of the gastric contents, so perhaps this slows the enzymatic process as well (thinking out loud here) - therefore, the whole noodles.
Now I'll get kinda gross here. I can tell you in humans (and with my dogs, actually) - that I've seen delayed emptying for more than 24 hours - and I've seen humans vomit what they've had for dinner
the next day (ie, some noodles, or whatever, are still in the tummy the next day). So, the tummy can stay quite still at times.
As for whether it's related to pancreatitis, you're wayyyyy more qualified to answer that question than me.
