THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The diagnosis of acute pancreatitis is usually based on the presence of abdominal pain and elevated levels of serum amylase and/or lipase.

Detailed explanation-2: -Acute pancreatitis usually presents with severe epigastric abdominal pain and elevations of serum amylase beyond three times the upper limit of normal. Elevated serum amylase levels usually return to baseline in 3 to 7 days.

Detailed explanation-3: -Acute pancreatitis presenting with normal serum amylase and lipase levels is a rare phenomenon. It is thought that typically, acute inflammation and auto-digestion of the pancreas leads to the release of both amylase and lipase, leading to elevated levels in the blood.

Detailed explanation-4: -When levels of lipase and amylase are higher than normal, it may indicate pancreatic injury or another disease. Most studies show that levels greater than three times the upper limit of normal usually lead to a diagnosis of pancreatitis, according to guidelines from the American College of Gastroenterology (ACG).
