Common causes of pancreatitis in clinical settings include biliary tract diseases, alcohol consumption, overeating, and hyperlipidemia, among others, with biliary tract diseases being the most common. Pancreatitis is generally defined as inflammatory changes in the pancreas due to self-digestion caused by various reasons. Clinical manifestations include abdominal pain, bloating, nausea, and vomiting, etc. Therefore, for patients with upper abdominal pain, it is necessary to further complete some examinations, such as liver function, amylase, lipase, abdominal ultrasound, and even abdominal CT scans, to clarify the diagnosis, which is generally straightforward for pancreatitis. The treatment of pancreatitis, in addition to symptomatic treatment, requires etiological treatment, combining different causes of pancreatitis. For instance, if caused by hyperlipidemia, lipid-lowering treatment is generally needed; if biliary tract disease is considered, active treatment of the biliary disease is required.
