Objective：To investigate the procedure and efficacy of hepatic lobectomy in treating intrahepatic bile duct stones.
Methods：The clinical data of 83 patients with intrahepatic bile duct stones undergoing hepatic lobectomy from January 2003 to June 2010 were retrospectively analyzed. The stones were distributed on the left side of liver in 42 (50.6%) cases, on the right side of liver in 18 (21.7%) cases, and on both sides of liver in 23 (27.3%) cases. Twenty-eight (33.7%) patients had concomitant common bile duct stones, 15 (18.0%) patients also had stenosis of bile duct, and 2 (2.4%) patients were found to have intrahepatic cholangiocarcinoma of left liver. Of the patients on admission, the liver function of Child grade A, B and C accounted for 46 cases (55.4%), 30 cases (36.1%) and 7 cases (8.5%), respectively. The options of surgical procedure, postoperative complications and outcomes of the patients were statistically analyzed. 
Results： Postoperative complications occurred in 10 (12.0%) cases and 1 case (1.2%) died. Of the 83 patients, 71 (85.5%) cases showed no residual stone. Of the 12 (6.0%) cases who had residual stone fragments, the retained stones were removed completely in 7 (58.3%) cases and incompletely in 5 (41.7%) cases with cholangioscope. Of the 5 patients with incomplete stone removal, 3 cases refused further treatment and were lost of follow-up, and 2 cases underwent reoperation for residual stones due to the onset of symptoms 1 year later (the reoperation rate was 2.4%). The other 80 patients were followed up for 2 months to 3 years and no recurrence was found.
Conclusions：Hepatic lobectomy is an effective method in treating intrahepatic bile duct stones and has high complete stone removal rate and low mortality. It carries low reoperation rate when combined with use of cholangioscopy.
