Introduction:
Long-term risk of acute pancreatitis (AP) and pancreatic cancer (PC) with mildly elevated lipase (MEL) is not well established.
Methods:
Multicenter retrospective cohort study-"MEL" group had MEL without AP; "no MEL" group had abdominal pain but normal lipase, imaging, endoscopy, and labs. Primary outcomes were incidence of AP or PC in MEL vs no MEL after at least 10-year follow-up.
Results:
9,447 patients met inclusion criteria (5,851 MEL, 3,596 no MEL). Logistic regression identified MEL as an independent predictor of AP (2.8% vs 1.2%, odds ratio 2.6, P < 0.001) but not PC (0.4% vs 0.3%, odds ratio 0.7, P 0.38).
Discussion:
MEL was associated with increased long-term AP risk.

01:27Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
01:24Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Lipolysis: The Breakdown of Lipids:
Lipolysis is the process of breaking down lipids, particularly triglycerides, into glycerol and fatty acids. This process typically occurs in the adipose tissue and is triggered by various hormones, including glucagon and...

Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
