What is the prognosis of pancreatitis with peripancreatic effusion? As we all know, the most common causes of pancreatitis in our country are mainly biliary stones, long-term alcoholism, hyperlipidemia, overeating, etc. Once pancreatitis breaks out, it can lead to a large amount of pancreatic enzymes exuding, corroding the tissues and organs in the abdominal cavity and causing tissue necrosis, which can cause a large amount of peripancreatic exudate. A small amount of peripancreatic fluid can be slowly absorbed on its own as the condition improves. If a large amount of peripancreatic fluid is accompanied by acute abdominal infection, it can often form peripancreatic pus, which often cannot be absorbed on its own and requires ultrasound-guided puncture and drainage or surgical removal of necrotic tissue and drainage treatment. Generally speaking, peripancreatic fluid without abdominal infection in pancreatitis patients is often absorbed slowly on its own in 2-3 weeks, which is mostly seen in acute edematous pancreatitis. In contrast, the peripancreatic fluid in patients with acute necrotizing pancreatitis is often combined with abdominal infection and the formation of peripancreatic pus. In this case, abscess drainage treatment is required, and such effusions tend to recur and are not easily absorbed within a short period of time, and in patients with a long course of the disease, it can take up to 2-3 months. It can be seen that the absorption time and prognosis of peri-pancreatic fluid is different for different degrees of pancreatitis, so the absorption time of fluid can be determined by first clarifying the condition of pancreatitis.
