That the poo is wiered is not surprising if she doesn't really eat, imho not necessarely enteritis. By now she should recover from anaesthesia, if in doubt contact your vet.
Getting some food into them can help kickstart their appetite, so getting some stuff into them via syringe might help.
If she doesn't drink either do give her water with a syringe, also the simethicone and meloxicam (can't tell about the other stuff, no experience with that)
What is her normal diet, what is she used to? If you have apple trees around or (untreated) roses I would try to offer the leaves, or grass (rather a small amount if she isn't used to it), or safe weeds like narrowleaf plantain.
I sometimes hold a handful of grass or hay against their nose until they are annoyed and bite into it to move it out of the way - sometimes, once it's in their mouth, they keep munching (I quickly retreat then)

Good luck
