What are the sequelae of acute pancreatitis patients after surgery? We all know that acute pancreatitis is divided into acute light pancreatitis and severe acute pancreatitis, acute pancreatitis often develops faster, the condition is dangerous, crisis patients’ lives, so patients with acute pancreatitis must pay attention to the condition of active treatment, but there are still some patients with severe acute pancreatitis with the aggravation of the condition, often need surgery to save the patient’s condition. Usually the principle of surgery for acute pancreatitis is the removal of necrotic tissue and continuous local irrigation and drainage. However, the following complications are common after surgery: 1. Residual infection of the retroperitoneum can be clarified by sinus imaging to identify the site and extent of infection, as well as the adjacent relationship, to create conditions for dilation and drainage of the residual cavity. 2, pancreatic fistula, intestinal fistula once the gastrointestinal fistula must keep the drainage open, strengthen nutritional support, small leaks can slowly heal. 3, abdominal bleeding pancreatitis exudate erosion of large blood vessels or rebleeding of blood vessels after surgery can cause abdominal hemorrhage, serious abdominal bleeding often requires reoperation, a small amount of bleeding can be closely observed. 4. Patients with acute pancreatitis are often bedridden for a long time resulting in pleural effusion, plus lung infection caused by abdominal inflammation, which should be strengthened to fight infection and exercise lung function. 5, lower limb venous thrombosis after pancreatic surgery patients often reduce lower limb activities while bedridden, which can cause lower limb thrombosis, and anticoagulation therapy can be given appropriately.
