What does high urine amylase represent, high urine amylase, and normal blood amylase?

If it is gallstone surgery, it is likely that the stone blocks the pancreas, causing the amylase in the pancreas to not be discharged, and it runs out of the blood, and then pulls out of the urine. After a long time, you will get pancreatitis. As for the second item, a CT will make it clearer, and B-ultrasound may not be clear.

There are no contraindications to postoperative meals, but you should eat less fat, otherwise you will have diarrhea.

Urine starch is the amylase produced by the body's pancreas that is excreted from the urine. When inflammation occurs in the pancreas, amylase is excreted in the urine, resulting in an increase in urinary amylase. Blood amylase is elevated after pancreatitis.

After a long period of time, blood amylase decreases to normal, and urine amylase remains elevated, suggesting that pancreatitis has passed for some time.

If urine amylase is only elevated, abdominal ultrasonography and abdominal CT are indicated. If pancreatitis is found, it needs to be treated aggressively. Avoid high-fat diets, use products that inhibit pancreatic secretion, etc.

Disease analysis: Amylase is a digestive enzyme secreted by the pancreas, which is discharged into the duodenum with pancreatic juice through the pancreatic duct. Measurement of urine amylase is primarily used in the diagnosis of pancreatitis.

Guidance: Elevated urinary amylase is seen in acute pancreatitis generally begins to increase 12 hours after the onset of the disease.

1000u l, which can be diagnosed as acute pancreatitis. Lasts 3 to 10 days to return to normal, lasts slightly longer than in the blood 5-7 days. moderately elevated in acute episodes of chronic pancreatitis; Dehydration, shock, secondary renal dysfunction, pancreatic cancer, pancreatic trauma, common bile duct obstruction, cholelithiasis, gastric ulcer perforation, mumps, alcoholism, etc., it is recommended to test for blood amylase to rule out pancreatitis.

Elevated serum amylase is not always pancreatitis. There are some diseases that have clinical manifestations similar to pancreatitis, and serum amylase can also be elevated, such as peptic ulcer perforation, appendicitis, intestinal obstruction, myocardial infarction, ectopic pregnancy and mesenteric artery embolism mentioned above. I once met a 65-year-old female foreign teacher who was diagnosed with hemorrhagic pancreatitis before her death, and was diagnosed with ruptured aneurysm with abdominal aortic dissection after her death.

Although serum amylase is also elevated in other major diseases, the clinical manifestations are completely different from acute pancreatitis and are easy to distinguish, such as mumps, parotid tumors, pancreatic cancers, periampullary cancers, ovarian tumors, salpingitis, acute and chronic renal failure, after abdominal surgery, after cardiac surgery, diabetic ketosis, and intravenous adrenal corticosteroids (such as hydrocortisone, dexamethasone), etc.

Serum amylase** is different. The "main factory" in the body for making amylase is the pancreas, and once the pancreas is destroyed, the "product" leaks into the bloodstream, and the level of amylase in the blood rises.

The salivary glands also produce a certain amount of amylase, usually we chew rice or steamed bread in the mouth for a long time, the longer the sweeter it is, because the salivary amylase hydrolyzes the starch in the food into glucose. The serum amylase system measured at ordinary times is the sum of these two amylases, and each accounts for 50. If serum amylase is elevated and ** is unknown, it can be distinguished by more precise immunoelectrophoresis.

Sometimes the absolute amount of amylase in the blood is not much, just because the kidneys are diseased, the amylase can not be excreted normally, so it accumulates in the blood, just as the water in the pool is constant and the drainage is not smooth, and the water in the pool will also increase, which is the reason for the increase in serum amylase in some kidney diseases.
