What Are the Effects of Coolsculpting on Lipomas (Hard Fat Tissue)?

It does not sound like it was a lipoma that was on your abdomen. Lipomas normally are deeper and do not burst on the surface of the skin. It is probably best to leave it alone and have your dermatologist take a look at it.

If you got anything out of a growth on the skin, then it is probably not a lipoma. Lipomas are fatty collections or benign tumors of the subcutaneous compartment and don't discharge their contents. angiolipomas also tend to be deeper and don't spontateously discharge.

If your lesion changed, ruptured, bled or oozed white material, it was most likely a cyst, not a lipoma.  I recommend having it checked by a dermatologist.

you may have a cyst in the abdomen.  lipomas are solid fatty tumors and can not "burst" or be "squeezed out."  lipomas can increase and decrease in size but this is typically relatively slow and not rapid.  it is not clear what lipomas or cysts will do in the face of coolsculpting.  it is probably not dangerous to do, but i would doubt that these would reduce in size with treatment.

Coolsculpting has been used to treat lipomas even though it is not an FDA approved use. The critical point is making sure that it is in fact a lipoma. I would suggest you follow up with your surgeon to discuss as your symptoms are not common.
