When intrahepatic bile duct stones are accompanied by calcification, the volume may increase. The calcification is a description found in ultrasonography and CT imaging, and is considered a benign lesion that does not require special treatment. Regular follow-up with ultrasound can be conducted to dynamically observe changes in volume, which generally tends to increase at a relatively slow pace. Of course, for patients with intrahepatic bile duct stones, if acute cholangitis occurs repeatedly, it will manifest as discomfort or pain in the upper right abdomen. Therefore, early surgical treatment should be undertaken to fully address the issue. The mentioned method mainly involves laparoscopic choledocholithotomy, which can achieve better treatment outcomes.
