Bilateral liver resection for bilateral intrahepatic stones.
OBJECTIVE
To evaluate the short- and long-term outcomes of bilateral liver resection for bilateral intrahepatic stones.


METHODS
We reviewed retrospectively 101 consecutive patients with bilateral intrahepatic stones who underwent bilateral liver resection in the past 10 years. The short- and long-term outcomes of the patients were analyzed. The Cox proportional hazards model was used to identify the risk factors related to stone recurrence.


RESULTS
There was no surgical mortality in this group of patients. The surgical morbidity was 28.7%. Stone clearance rate after hepatectomy was 84.2% and final clearance rate was 95.0% following postoperative choledochoscopic lithotripsy. The stone recurrence rate was 7.9% and the occurrence of postoperative cholangitis was 6.5% in a median follow-up period of 54 mo. The Cox proportional hazards model indicated that liver resection range, less than the range of stone distribution (P = 0.015, OR = 2.152) was an independent risk factor linked to stone recurrence.


CONCLUSIONS
Bilateral liver resection is safe and its short- and long-term outcomes are satisfactory for bilateral intrahepatic stones.
