Glucose in the small intestine is taken up from the lumen by an S-GLUT cotransporter.
On the basal surface glucose passes into the blood stream by facilitated difussion.
So far is this correct?
If so does this mean that HYPOTHETICALLY if someone did not eat anything but injected themselves with sugar (e.g: they are being fed through injection) that glucose could be taken UP by these intestine epithelial cells from the blood stream?

No.
If you are injecting into the blood stream….then I am not sure why you would think it would be taken up by the intestinal epithelial cells.
Intestinal epithelial cells absorb whatever they need from the intestine not the blood.

I mean that if someone wasn't eating (AT ALL) and they were being fed via their blood stream (parenteral nutrition) could the transporters bring sugar FROM the blood stream TO the intestinal cells?

It wouldn't bother taking it back to the intestine
