Acute pancreatitis is usually secondary to biliary tract disease, overeating or alcoholism, patients have obvious abdominal pain, abdominal distension, nausea, vomiting and other related symptoms, need to be treated systematically, the specific diagnostic and therapeutic norms include the following aspects: First, patients are advised to abstain from food and water, at the same time, also need to be retained in the gastrointestinal decompression tube, the purpose is to reduce the stimulation of pancreatic fluid secretion after eating, sustained gastrointestinal decompression can be diverted to the outside of the body to reduce the impact of digestive fluids on patients. Continuous gastrointestinal decompression can drain the digestive fluids outside the body and reduce the effect of abdominal distension on the patient. Because of severe abdominal distension, it will also affect the patient’s breathing. Secondly, systematic anti-infection treatment should be carried out, patients with pancreatic cancer are easy to combine with the infection of the abdominal cavity, and in serious cases, infectious shock is also easy to occur. Thirdly, intravenous nutritional support, inhibition of glandular secretion, protection of digestive tract mucosa and other symptomatic treatment should be carried out.
