I once rescued a bearded dragon that was totally impacted from eating only crickets* plus some of his substrate (wood shavings) in desperation.
*The large back legs of crickets are very hard to digest & can cause constipation, especially if ingested with loose substrate- that would compound the problem.
Also (this may not apply to you since you said she doesn't like mealworms?) I've heard that some mealworms have chewed the insides of the lizard that swallowed
them without adequately chewing & killing them, so when I've fed mealworms to lizards, I offered with tongs & simultaneously crunched the head as it was taken.
(please don't report me for cruelty to mealworms)
BTW, I don't know if this will help your leopard gecko or not, but if she's impacted, I don't see her surviving surgery...? By all means consult a vet...but in the
meantime, what my exotic animal vet told me to do for that bearded dragon was a daily oral dose of mineral oil (by plastic dropper...don't use a glass dropper
because they might bite hard enough to break the glass). At the same time (& despite my vet's skepticism) I soaked the dragon in warmish bathwater for about 30 minutes or so per day. In a couple days, he did huge consecutive dumps for several days while in the bathwater...the hydration helped, trust me.
But the (indigestible) mineral oil made his G.I. contents slippery enough to be expelled normally without internal harm (he was SO lucky not to have perforated
his colon with those wood shavings he ingested). Good luck!
