Is acute pancreatitis serious and what is the prognosis? We all know that pancreatitis is a relatively common surgical emergency, often divided into two types of acute edematous pancreatitis and acute necrotizing pancreatitis. Generally speaking, 80% of acute pancreatitis belongs to acute edematous pancreatitis. Acute edematous pancreatitis is often mild, and through conservative treatment such as active rehydration, anti-infection, liver protection, gastric protection and tight diet, the vast majority of patients are treated well and no serious complications occur. Especially for acute pancreatitis induced by hyperlipidemia, it can be treated mainly by fasting and rehydration, and the blood lipids can be slowly reduced to normal in about 5-7 days to improve the clinical symptoms of patients. Acute necrotizing pancreatitis often has a rapid onset, progresses quickly, is more dangerous, and has a high death rate. Acute necrotizing pancreatitis often causes serious pancreatic parenchymal necrosis, which can lead to more serious abdominal infection and even infectious shock and multiple organ dysfunction. In addition, patients with severe acute pancreatitis lead to necrosis of the pancreas and peripancreatic tissue, causing the formation of abscesses in the abdominal cavity, which often require surgical debridement and drainage treatment. Patients with severe acute pancreatitis often face complications of severe systemic infections in the later stages, which threaten their lives. This shows that the vast majority of light pancreatitis treatment effect is better, only severe acute pancreatitis effect is worse, will be critical to the lives of patients, so pancreatitis patients once there are changes in the condition to seek medical treatment in a timely manner to avoid aggravation of the disease, affecting the prognosis.
