Acute pancreatitis is a common disease in abdominal surgery, and the incidence of severe pancreatitis has gradually increased in recent years. Because it disrupts physiology greatly and causes significant damage to important organs, the mortality rate is very high. Sometimes it can cause sudden death. The mortality rate of severe pancreatitis is 20%, and the mortality rate for patients with complications can be as high as 50%. Clinical pathology often divides acute pancreatitis into two types: edema type and hemorrhagic and necrotic type. Although this classification method can explain its pathological condition, the development of pancreatitis is not static. With the degree of pancreatic duct obstruction and changes in the pancreatic interstitial blood vessels (arteries, veins and lymphatic vessels), the pathological changes are in Dynamically developing. Therefore, the classification method of acute mild pancreatitis and severe pancreatitis is more suitable for clinical application. Clinicians often attach great importance to severe pancreatitis (such as hemorrhage and necrosis type), but mild pancreatitis (such as edema type) cannot be ignored, as it can develop into severe pancreatitis.

The biggest cause of associated gastric bleeding may be stress ulcers: stress states caused by severe infection, surgery, trauma, shock, adrenal glucocorticoid treatment and certain diseases.

It is recommended to go to a qualified hospital for diagnosis and treatment without delay.
