Background:
Hepatic resection is main approach to treatment of hepatolithiasis, but the long-term follow-up results of hepatic resection for hepatolithiasis are rarely reported.
Methods:
A retrospective study was conducted of 87 patients with hepatolithiasis who underwent hepatic resection.
Results:
The final stone clearance rates were 95%. There was a significant difference in the incidence of recurrent stones between patients with and without remaining biliary strictures. On multivariate analysis, the presence of residual or recurrent stones was an independent risk factor associated with recurrent cholangitis. The 10-year overall survival rate was 80.3%. On multivariate analysis, the development of cholangiocarcinoma was an independent predictor of survival in patients who underwent hepatic resection for hepatolithiasis.
Conclusions:
The long-term outcomes after hepatic resection were satisfactory in patients whose intrahepatic stones and strictures were completely removed. Cholangiocarcinoma associated with hepatolithiasis was an independent prognostic factor in patients with hepatolithiasis who underwent hepatic resection.
