The pancreas is a retroperitoneal organ, located in the supra-abdominal region and the left quadrant of the rib region, with a relatively deep location under the saber in the upper abdomen. It is located in the front of the spine at the flat first lumbar vertebra and the posterior part of the stomach also called the stomach bed, and is divided into four parts: the head, neck, body and tail of the pancreas, which are important digestive organs of the body. It contains a variety of functional secretory cells, such as glucagon, insulin, and gastrin. They are involved in the digestion and absorption of substances and are responsible for regulating the physiological functions of the whole body. If these cells become diseased, there will be an excess or deficiency of secreted substances, resulting in lesions such as acute pancreatitis. Most of them will show symptoms such as abdominal pain, abdominal distension, nausea, vomiting and fever. Generally, the diagnosis can be clarified through pancreatic ultrasound or CT examination and blood and urine amylase examination.
