For patients with intrahepatic bile duct stones, acute cholangitis may occur, which can cause fever and significant upper abdominal pain. At this time, antibiotic treatment should be used to control the infection, and the condition can be alleviated once the inflammation is under control. Moreover, if the condition recurs repeatedly, surgical treatment should be chosen. Only by surgically removing the stones can the symptoms be completely cured. Patients with intrahepatic bile duct stones should also be careful with their diet. They should avoid spicy and irritating foods to reduce inflammation, and eat more fresh vegetables and fruits that are rich in vitamins to better promote recovery. Patients who have undergone surgery should also have regular ultrasound check-ups to dynamically observe changes in their condition.
