The current strategy, which tends to be consistent at home and abroad, is summarized as follows: in the early stage of SAP, non-surgical treatment centering on the maintenance of organ function is adopted, aseptic necrosis is treated non-surgically as far as possible, and surgical treatment is adopted after the emergence of necrotic infection. 1, non-surgical treatment SAP should be monitored and treated in ICU in the early stage of the disease, and the principle is to replenish body fluids, maintain water-electrolyte balance, energy support, and prevent the emergence of local and systemic complications. Monitoring includes: vital signs, Sao2, urine volume/2h, electrolytes, calcium, magnesium, phosphorus, muscle liver, urea nitrogen/8h, blood count, arterial blood gas, chest X-ray. Early management includes: fluid resuscitation, oxygen therapy, fasting, analgesia, H2 receptor antagonists, gastrointestinal decompression, etc. The focus is on the maintenance of organ function. Special treatment includes: enzyme inhibiting agents, anti-pancreatic secretagogues, platelet activating factor antagonists: Leipafant, prophylactic use of antimicrobial antibiotics: in the use of antimicrobial antibiotics, carbene antibiotics are recommended for those with pancreatic necrosis. Prevention and control of early complications ARDS, acute renal failure, shock, DIC, metabolic encephalopathy. In addition to this several explorations in the non-surgical treatment of SAP are currently being carried out around the world, including continuous hemofiltration and peritoneal lavage. However, its role has yet to be confirmed by further studies. 2. Surgical treatment includes: 2.1. Pancreatic necrotic tissue removal is performed by blunt or with suction, removing necrotic tissue, placing drains in the pancreatic bed, small omental sac, bilateral posterior colon, etc., and continuous local irrigation and drainage. From the clinical data, the operation of pancreatic necrotic tissue removal is more reasonable, simple and easy to perform, less damaging, less complications and lower mortality. 2.2. Open abdominal tamponade: The pathological changes of severe acute pancreatitis are progressive, so there is no procedure that can completely treat the disease at once. The method is to fully free the pancreas after opening the small omental sac and remove necrotic tissue, cover the exposed transverse colonic mesentery, large vessels, and posterior gastric wall with non-adhesive porous gauze for protection, and then block it with saline gauze. The abdominal wall can be loosely sutured; a “sandwich” technique can also be used, in which a polypropylene (Marlx) mesh is placed over the exposed viscera or omentum and then sewn to the bilateral fascial edges of the incision, covered with a transparent surgical adhesive towel, with a suction tube placed between the two layers; the adhesive towel is removed at each dressing change, the mesh is cut into the abdomen, and the mesh is sutured at the end of the procedure. At the end of the operation, the mesh sheet was sutured and covered with transparent surgical adhesive towel, and the “sandwich” structure was restored. Each of these two methods has its own advantages and disadvantages. Several methods have been proposed to close the abdomen, the principle being simplicity, ease of re-dose, and prevention of mixed infections.
