Can you?

Yes, I'm on an all liquid diet for 2 weeks pre-op. Just waiting for my surgery date to start the diet. My Nut also said Cream of Wheat and sugar free jello

Everyone's preop diet is different....this is a question for your surgeon.

I would strain the broth and drink that. I would not risk food, mostly because your stomach may not react nicely to it. If it's a thick Soup, I would Water it down, then strain and again leave out any meat or vegetables. Don't risk your surgery on a few morsels. It's important to prep your stomach for post surgery. I know my surgeon wants a dry tummy when he goes to work. If you have to chew it, don't eat it.

Follow your surgeon's recommendations.

My surgeon said I could do full liquids but every surgeon is different, I suggest asking your surgeon if it's okay.

From the future sleeve's perspective, it doesn't matter at all what you have three days before surgery (I probably had steak, but don't really remember,) but different surgeons have different policies for pre-op dieting for different reasons. Those that do such diets can vary between liquids only for some weeks before to some combination of Protein shakes and low carb meals to meat, veg and salads only. A real big YMMV
