Pancreatolithiasis, also known as pancreatic duct stones, is one of the clinical manifestations of chronic pancreatitis, with an onset age of 30 to 50 years old, and a higher incidence in Europe and the United States than in the East. Pancreatolithiasis is caused by poor lifestyle habits, and its risk factors are mainly the following: 1, alcoholism: alcoholism is the most important risk factor for pancreatolithiasis. The concentration of protein in the pancreatic fluid of long-term alcoholics is significantly higher, forming protein deposits to form protein plugs, the latter by calcification and the formation of stones. 2, smoking: smoking is one of the risk factors of pancreatic stone disease, the incidence of pancreatic stone disease in smokers is 2-3 times higher than non-smokers. 3, diet: high-fat, high-protein, low-fiber diet is prone to pancreatic lithiasis. Eating too much fat leads to impaired fat metabolism, increased cholesterol and free fatty acids in the blood, which can inhibit the body’s immune function; high-fat, high-protein diet increases bile secretion, bile salts and fatty acids in the intestinal tract under the action of anaerobic bacteria can form lithogenic substances, inducing pancreatic lithotripsy. Epigastric pain is the most common symptom of pancreatic lithotripsy, which is caused by obstruction of the pancreatic ducts and fibrosis of the pancreas. Long-term pancreatic stones lead to pancreatic fibrosis causing pancreatic exocrine function depression may result in wasting and steatorrhea. Some patients may develop jaundice, diabetes mellitus or even cancer. Pancreatic lithiasis can be detected by ultrasound, CT, MRI or endoscopic retrograde cholangiopancreatography (ERCP). In those with mild symptoms, conservative, symptomatic medical management is the main focus. Surgical intervention is often required at later stages, including trans-pancreatic ductoscopic lithotomy, pancreatic duct jejunostomy, pancreatic head resection with preservation of duodenum or pancreaticoduodenectomy. Pancreatic lithotripsy is mainly caused by bad habits, so to prevent pancreatic lithotripsy, we must first eliminate these bad habits. The main points include the following: 1. Quit smoking and drinking Clinically, the occurrence of pancreatic stone disease is mainly related to long-term heavy drinking, drinking for a long time, a large amount of people are prone to the formation of 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. Patients still need to quit smoking and drinking after surgery, otherwise they are prone to recurrence. 2, adjust the recipe In addition to abstaining from alcohol, daily meals need to be reasonably matched, try to eat less food 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. 3, 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.
