Pancreas is an important digestive organ deeply hidden in the retroperitoneum, with hidden position, special structure and complex function, which people understand and recognize late and incompletely. Pancreas has two major functions, exocrine and endocrine, exocrine secretion of a variety of digestive enzymes to digest and decompose sugar, protein and fat in food; endocrine secretion of a variety of hormones, such as insulin, etc., to regulate a variety of important physiological functions of the human body. What are the common pancreatic diseases? Pancreatic diseases mainly include acute pancreatitis, chronic pancreatitis, pancreatic cancer, pancreatic cysts, pancreatic endocrine tumors and secondary endocrine diseases such as diabetes. With the improvement of our people’s living standards, changes in lifestyle and dietary habits, increased consumption of alcoholic beverages, and the intensification of environmental pollution, its incidence rate is significantly higher than in the past. Pancreatic diseases are difficult to diagnose and treat, with poor efficacy, many sequelae and high mortality rate, which has seriously threatened patients’ life, health and quality of life. Early medical treatment, timely and accurate diagnosis, scientific and reasonable treatment, especially the pioneering application of new technologies, can greatly improve the cure rate, reduce the sequelae, lower the death rate and improve the quality of life.
