One of the hazards of pancreatitis, local complications. Pancreatic abscess refers to an abscess wrapped around the pancreas, which is formed by necrosis and liquefaction of pancreatic tissue and secondary infection. It often appears two weeks after onset. At this time, the patient has high fever with poisoning symptoms, abdominal pain is aggravated, and the upper abdominal mass can be touched, and the white blood cell count is obviously increased. The puncture fluid is purulent and bacteria grow in culture. Pancreatic pseudocyst, the fluid around the pancreas is not absorbed and is wrapped by fibrous tissue to form pseudocyst. Most of them are formed after three weeks of onset. Physical examination can often touch the upper abdominal mass, and larger cysts can compress adjacent tissues to produce corresponding symptoms.

The second hazard of pancreatitis is systemic complications. Organ failure can occur in one or more organs, with different degrees, and severe cases show multiple organ failure. Mainly circulatory failure, manifested as shock. Arrhythmia and heart failure. Acute respiratory failure or acute respiratory distress syndrome is characterized by dyspnea and rapid development of cyanosis, which can not be relieved by conventional oxygen therapy. Acute renal failure is characterized by oliguria, progressive increase of blood urea nitrogen and creatinine. Gastrointestinal bleeding, manifested as hematemesis, black stool or bloody stool, stool occult blood test positive. The spread of infectious diseases can lead to septicemia. In the later stage, due to the extremely low body resistance and the extensive use of antibiotics, fungal infection is prone to occur.
