Pancreatogenic abdominal pain is one of the symptoms of chronic pancreatitis (chronic pancreatitis), which is a persistent and permanent damage of pancreatic tissue and function caused by various factors. The pancreatic gland shows different degrees of alveolar atrophy, pancreatic duct deformation, fibrosis and calcification, as well as different degrees of pancreatic exocrine and endocrine dysfunction. Typical chronic pancreatitis is relatively rare in China, and it is difficult to confirm the diagnosis. The following diseases are also causes of pancreatic origin abdominal pain: 1. Acute edematous pancreatitis Acute edematous pancreatitis (or acute interstitial pancreatitis) is a common type of acute pancreatitis. It can be cured by non-surgery and is basically an internal disease. There are many causes of acute pancreatitis, and there are regional differences. In China, more than half of them are caused by biliary tract diseases, and in Western countries, alcoholism is also the main cause, in addition to gallstone disease. Biliary system diseases, alcohol or drugs,. Infection, hyperlipidemia and hypercalcemia, surgical trauma, atherosclerosis and periarteritis nodosa, late pregnancy, penetrating ulcers, mental, genetic, allergic and allergic reactions, diabetic coma and uremia, pancreatic duct obstruction, pancreatic duct stones, stenosis, and tumors may cause. 2, pancreatic trauma The pancreas is a gland with endocrine and exocrine functions, and its location is deep in, protected by the rib arch in front and the spine in the back, so there is less chance of injury, so it is often easy to misdiagnose. It was not until 1952 that a comprehensive report on pancreatic injury was made. Pancreatic injury accounts for 0.4/100,000 of the population and 0.2-0.6% of abdominal trauma. Most wartime pancreatic injuries are penetrating injuries, often with high mortality due to associated hemorrhage. On average, they are mostly due to severe closed abdominal injuries. Sometimes it is a surgical misadventure. The ratio of penetrating to closed pancreatic injuries is about 3:1. In a group of 1984 cases of pancreatic trauma, penetrating injuries accounted for 73% and closed injuries accounted for 27%. 3, acute pancreatitis Acute pancreatitis (AP) is a relatively common type of acute abdomen, and its incidence accounts for the third to fifth place in acute abdomen. More than 80% of patients have mild disease, namely acute edematous pancreatitis, which can be cured by non-surgery and is basically a medical disease. 10% of patients have severe pancreatitis, namely acute hemorrhagic necrotizing pancreatitis, in which the inflammation of the pancreas is not reversible or self-limiting and often requires surgical treatment and should be considered a surgical disease. Due to the deeper understanding of acute pancreatitis, diagnostic techniques and treatment methods have been more developed and have become of great interest to surgeons, while the death rate remains high at 30% to 60% and prone to various serious comorbidities, which is a serious challenge to physicians.
