Background Hepatic resection is the treatment of choice for unilateral intrahepatic stones. The availability of the flexible choledochoscope has greatly changed the management of intrahepatic stones. Little has been reported regarding hepatic resection for bilateral intrahepatic stones.

Methods Fifty-nine (15·1 per cent) of 392 patients with bilateral intrahepatic stones underwent hepatic resection. The indications and results were reported. Surgical outcome and long-term follow-up were analysed, and results were compared with those in patients not undergoing hepatectomy.

Results Fifty-nine patients underwent hepatic resection because of destruction of the left liver by repeated infection (n=40), multiple cholangitic liver abscesses (n=18) or associated intrahepatic cholangiocarcinoma (n=1). The hospital mortality rate was 1·7 per cent. The majority of complications were wound infection (9 per cent), haematobilia (5 per cent) and biliary fistula (3 per cent). The incidence of residual stones after surgery was 60 per cent. One year after postoperative choledochoscopic stone extraction, the rate of complete stone clearance was 84 per cent. In patients who did not have hepatectomy the respective rates were 90·1 and 52·9 per cent. The recurrence rate for stones in the hepatectomy and no-hepatectomy groups was 12 and 33·0 per cent respectively.

Conclusions Compared with patients not undergoing hepatectomy, those having hepatic resection had similar operative risks, fewer residual stones and a low incidence of recurrent stones (P<0·05).
