If intrahepatic bile duct stones are present without obvious symptoms, no special treatment is needed at this time. It is advisable to regularly re-examine with ultrasound and dynamically observe any changes in size. Of course, diet should avoid spicy and irritant foods, mainly light foods, and consume more fresh vegetables and fruits to reduce inflammatory stimulation and better control the progression of the disease. If there are significant symptoms, there will be obvious pain in the upper right abdomen, and possibly nausea, vomiting, and other gastrointestinal symptoms. Therefore, the treatment should involve early surgical intervention, as surgery is the only way to achieve a cure. The main surgical method is laparoscopic choledochotomy for stone removal.
