Pancreatic necrosis is a more serious disease that can be life-threatening; however, it is possible to cure it if treated in time. Pancreas is an elongated organ located in the retroperitoneum with endocrine and exocrine functions. If the pancreas develops lesions, such as when acute pancreatitis occurs, pancreatic necrosis can occur in severe cases, with abdominal pain, nausea and vomiting, and complications such as peritonitis, shock, etc., and then systemic multiorgan failure occurs, with a high case-fatality rate. Therefore, if pancreatic necrosis occurs, it needs to be treated immediately, and the earlier the intervention, the more likely to be cured. Surgery should be the treatment of choice for necrotizing pancreatitis, and the most common procedure is necrotic tissue removal plus drainage. The most common surgical procedure is necrotic tissue removal with drainage. The abdominal cavity is explored laparoscopically or openly, and the necrotic tissue and pus are completely removed and thoroughly flushed out before placing a drain. If you feel unwell, please seek medical attention.
