Hepatolithiasis is a common disease in China with a high rate of residual stones up to 30％-90％ after surgery.Patients often require re-operation because the high rate of residual stones and stone recurrence.Because the calculi are deeply distributed in the liver,and the condition is often accompanied by anatomical variations,distortion and biliary strictures,traditional preoperative imaging examinations do not easily locate the lesioos precisely,making diaguosis and treatment difficult.In recent years,three-dimensional computed imaging and visual simulation have provided a novel preoperative diagnostie method for hepatolithiasis,and have offered a clearer radiologic basis for surgical planning.The value of digital medical technology in the diagnosis and treatment of hepatolithiasis is discussed in this article.
