Patients with intrahepatic bile duct stones generally do not experience facial pigmentation. The symptoms of intrahepatic bile duct stones primarily manifest as acute cholangitis, with noticeable right upper abdominal pain, and may be accompanied by nausea, vomiting, abdominal distension, diarrhea, and other gastrointestinal symptoms. Some patients may also exhibit symptoms of systemic infection such as chills, high fever, and fatigue. Additionally, obstructive jaundice can occur, characterized by lighter stool color, darker urine color, and yellowing of the skin and mucous membranes. However, facial pigmentation generally does not occur. Therefore, for patients with recurrent intrahepatic bile duct stones, early surgical treatment should be considered. Surgery is the only definitive treatment to relieve the condition effectively.
