Pancreatic stone obstruction, also known as pancreatic stone disease, pancreatic stones, is a relatively rare disease, which has been reported to account for 0,09% to 0,13% of autopsy material, with an increasing trend in recent years. Clinical symptoms abdominal pain is the most common, accounting for about 62%. The pain is located in the mid-upper abdomen or left upper abdomen, mostly recurrent and persistent, a few are dull pain, which can radiate to the back, shoulder and left rib margin, and is related to eating. It causes steatorrhea and malnutrition, jaundice and diabetes mellitus. Due to the obstruction of pancreatic duct by pancreatic stone and the destruction of pancreatic tissue, it leads to insufficient exocrine function of the pancreas and causes steatorrhea and malnutrition. The key to prevent pancreatic stone obstruction: a. Quit smoking and alcohol Clinically, the occurrence of pancreatic stone disease is mainly related to long-term heavy alcohol consumption, drinking for a long time, the amount of alcohol is easy to form pancreatic stones. The incidence of pancreatic stone disease in smokers is 2-3 times higher than in non-smokers. Therefore, to prevent pancreatic stone disease, we must first quit smoking and alcohol. The abdominal pain of pancreatic stone disease will be relieved after quitting smoking and drinking. After surgery, patients still need to quit smoking and alcohol, otherwise they are prone to recurrence. Second, adjust the recipes In addition to abstaining from alcohol, daily meals need to be reasonably matched, as little as possible to eat foods high in fat, oil and salt, with cereals, beans, sweet potatoes and other coarse grains as the main body of the diet. The intake of fat should be strictly limited to no more than 40 grams per day. Use more easily digestible sugars, such as brown sugar, cane sugar, honey, etc. Because carbohydrates are the main source of energy, they can be given more than 300 grams per day. Eat fresh vegetables and fruits daily to increase the intake of fiber, carotenoids, vitamin E and essential minerals. Use more cooking methods such as boiling, simmering and steaming, and do not use methods such as frying and stir-frying in oil. Third, physical exercise Participate in a moderate amount of physical activity to avoid overweight and obesity, which can help reduce the incidence of pancreatic stone disease. Physical activities include running, walking, swimming, playing ball, dancing, climbing stairs, cleaning rooms, etc.
