The idea of non-surgical treatment of severe pancreatitis has become very prevalent, but differences in the understanding of what non-surgical treatment entails have led to delays in treatment for many patients. Non-surgical treatment refers to the non-surgical treatment of the lesion of the pancreas itself, while the management of the cause of the disease requires aggressive management. In case of biliary pancreatitis, it is better to deal with the biliary tract problem as early as possible, which has two major measures, one is endoscopic treatment; if endoscopic treatment is difficult, open surgery or laparoscopic surgical treatment is required, it should be noted that if surgery is performed to deal with the biliary tract problem during the acute response period, the surgical approach is very important, only dealing with the biliary tract problem is sufficient, the pancreatic lesion is not overly treated, the pancreatic In principle, the peripancreatic membrane is not opened and the peripancreatic tissues are not separated, and only a drainage tube is left in the area of exudation. The author also encountered cases of traumatic pancreatitis that were treated non-operatively, and the patient was almost life-threatening before emergency surgery. Traumatic pancreatitis is commonly caused by trauma, and another type of trauma is caused by surgical trauma, such as colon surgery, gastric surgery or surgery on the tissue surrounding the tail of the pancreatic body can cause pancreatitis. In principle, traumatic pancreatitis requires emergency surgery to drain the exuding pancreatic fluid to prevent the expansion of internal burns, because traumatic pancreatitis is often caused by the rupture of pancreatic tissue, and its pathogenesis is not the same as that of general pancreatitis, so it should be treated differently. Pancreatitis caused by trauma can be treated non-operatively if there is only swelling of the pancreas, but changes in abdominal signs must be closely observed. Therefore, nonsurgical procedures are directed at the pancreas rather than the biliary tract, and patients with biliary tract problems should receive early intervention in the biliary tract rather than continuing nonsurgical treatment with the pancreas.
