Is there a difference between fat necrosis and skin necrosis? Dr. states I'm draining "liquified fat" from my JP drain (Photo)

If still concerned maybe see in interventional radiologist for a scan to see if fluid collection is present. Than under radiology they can drain and insert new indwelling drainage tubes... 

I think that there is a difference between liquified fat and seroma . Generally speaking the seroma is more clear than the liquified fat. About the skin necrosis I don't see at this moment, just superficial in the upper área of the abdomen. In the lateral area it look more damage of the skin . Consult your doctor to take a look of the result at thi time.
