Patients with acute pancreatitis who are complicated by peritonitis, large amounts of fluid in the abdominal cavity, and manifestations of abdominal infection and secondary shock need to opt for surgical incision and drainage in a timely manner. The cost of surgery varies with the lesion, with a simple dissection costing between$2,000 and$3,000. The cost increases if the patient requires purulent material removal, partial resection of the pancreas, and postoperative drainage. In addition, for patients with acute pancreatitis, it is also easy to complicate serious infections, and secondary to respiratory failure, acute respiratory distress syndrome, abdominal septal compartment syndrome, which can be life-threatening in severe cases, and the treatment cycle is relatively long, so the overall cost is a lot. The mortality rate of pancreatitis patients with severe disease is also very high, so for early patients with obvious signs of peritonitis, surgical treatment used to be more often chosen. Nowadays, the internal medicine conservative integrated treatment is more and more.
