For patients with intrahepatic bile duct stones who do not experience any discomfort, abdominal pain, or jaundice, it is possible to temporarily observe without special treatment. However, special attention should be paid to the diet. It is advisable to avoid spicy and stimulating foods such as chili peppers, barbecue, and garlic, as these inflammatory irritants may cause local inflammation and even lead to acute cholecystitis and cholangitis. Additionally, the diet should also avoid foods high in cholesterol and fats, such as animal offal and fatty meats, as these foods can exacerbate symptoms. Therefore, although patients with intrahepatic bile duct stones may not exhibit any symptoms, it is still important to pay attention to daily life.
