Mesenteric and retroperitoneal fat necrosis may be caused by fat saponification from pancreatitis, in which the damaged pancreas releases lipolytic enzymes, which autodigest the pancreatic parenchyma and peripancreatic fat tissues (23–25).
What is omental fat necrosis?
Fat necrosis occurs as a result of infarction of greater omentum, torsion of an epiploic appendage, or due to trauma or pancreatitis.
What is mesenteric fat necrosis?
Mesenteric fat necrosis causing bowel obstruction is a rare occurrence with only one case reported in humans. It is due to accidental or surgical trauma to the adipose tissue with extracellular liberation of fat or enzymatic lysis of fat due to the release of lipases resulting in fibrosis.
What is enzymatic fat necrosis?
In fat necrosis the enzyme lipase releases fatty acids from triglycerides. The fatty acids then complex with calcium to form soaps. These soaps appear as white chalky deposits. It is usually associated with trauma of the pancreas or acute pancreatitis.

It is usually not noticeable until 6-8 months after the surgery, once the tissue flap has softened and the swelling is gone. Doctors call these lumps fat necrosis.
How do you break up fat necrosis?
