I suggested the cloaca wash because the exotic's team at my university vet school has done it to one of my snakes. Your vet is right that snakes don't constantly have poop in their intestinal tract, but if you can palpate some, the wash does work. And I just assumed she still had some left over food from her previous feeding before her regurge.
Either way, I agree with you. If she has parasites, its been treated.
It sounds like things are looking positive for Manasha.
And is that her in your avatar picture, then she's gorgeous!
