When patients with pancreatitis are discharged from the hospital, medical staff should first introduce the causes of the disease to the patients and their families, and treat the causes that can be eradicated in a timely manner: for example, pancreatitis caused by gallbladder stones, the gallbladder should be removed as soon as possible; for pancreatitis caused by bile duct stones, endoscopic retrograde cholangiopancreatography should be performed as soon as possible to remove the stones in the common bile duct; for pancreatitis caused by alcoholism, alcohol should be strictly prohibited; for pancreatitis caused by hyperlipidemia, a good lifestyle should be adopted and lipid-lowering treatment should be performed if necessary. The pancreatitis caused by alcoholism should be strictly prohibited; pancreatitis caused by hyperlipidemia should be treated with a good lifestyle and lipid-lowering therapy if necessary. Secondly, for patients with pancreatic pseudocysts, they should regularly review pancreatic CT or MRI after discharge to observe changes in the size of pancreatic pseudocysts, and if the pseudocysts do not absorb on their own or increase in size, fever, abdominal pain, etc., they should promptly seek medical attention. Again, for older patients with acute pancreatitis, pancreatic CT or MRI should be reviewed at least once after discharge from the hospital because the cause of pancreatitis in a small number of elderly patients is due to malignant tumors of the pancreas or biliary system, and in the early stage of acute pancreatitis, a large amount of exudation from the pancreas and peripancreatic may mask the malignant tumor. Therefore, a review of pancreatic CT or MRI can help rule out malignancy. Finally, certain drugs, such as tachyphylaxis, anti-inflammatory pain and oral contraceptives, can easily induce pancreatitis, and self-administration of these drugs should be avoided as much as possible to avoid recurrence of acute pancreatitis.
