Serum amylase may be normal (in 10% of cases) for cases of acute or chronic pancreatitis (depleted acinar cell mass) and hypertriglyceridemia. Reasons for false positive elevated serum amylase include salivary gland disease (elevated salivary amylase), bowel obstruction, infarction, cholecystitis, and a perforated ulcer.
Smoking increases the risk of both acute and chronic pancreatitis. [3] [4] Diagnosis of acute pancreatitis is based on a threefold increase in the blood of either amylase or lipase. [1] In chronic pancreatitis, these tests may be normal. [1] Medical imaging such as ultrasound and CT scan may also be useful. [1] Acute pancreatitis is usually ...
Ranson criteria. Purpose. assess mortality risk of acute pancreatitis. The Ranson criteria form a clinical prediction rule for predicting the prognosis and mortality risk of acute pancreatitis. They were introduced in 1974 by the English - American pancreatic expert and surgeon Dr. John Ranson (1938–1995). [1]
The most common pancreatic disease is pancreatitis, an inflammation of the pancreas which could come in acute or chronic form. Other pancreatic diseases include diabetes mellitus, exocrine pancreatic insufficiency, cystic fibrosis, pseudocysts, cysts, congenital malformations, tumors including pancreatic cancer, and hemosuccus pancreaticus.
Chronic pancreatitis. Chronic pancreatitis is a long-standing inflammation of the pancreas that alters the organ's normal structure and functions. [1] It can present as episodes of acute inflammation in a previously injured pancreas, or as chronic damage with persistent pain or malabsorption. It is a disease process characterized by ...
Serum amylase is normal outside episodes of acute pancreatitis. It is difficult to diagnose HP because the bleeding is usually intermittent. Endoscopy is essential in ruling out other causes of upper gastrointestinal bleeding and in rare cases; active bleeding can be seen from the duodenal ampulla.
[17] [18] According to Cotton et al., PEP is defined as a "clinical pancreatitis with amylase at least three times the upper limit of normal at more than 24 hours after the procedure requiring hospital admission or prolongation of planned admission". Grading of severity of PEP is mainly based on the length of hospital stay.
A higher than normal concentration may reflect any of several medical conditions, including acute inflammation of the pancreas (which may be measured concurrently with the more specific lipase), [12] perforated peptic ulcer, torsion of an ovarian cyst, strangulation, ileus, mesenteric ischemia, macroamylasemia and mumps.
