MRI to compare the long-term outcomes of partial hepatectomy versus choledocholithotomy in the treatment of hepatolithiasis / 中华肝胆外科杂志

ABSTRACT

Objective To compare the long-term outcomes of partial hepatectomy versus choledocholithotomy both combined with choledochoscopy,for the treatment of hepatolithiasis.Methods Patients who underwent either type of the operations were followed up and examined using hepatobiliary magnetic resonance (enhanced MRI + MRCP).The incidences of abnormal imaging in the two groups were compared.Results Of 268 patients,138 patients underwent partial hepatectomy and the remaining 130 patients underwent choledocholithotomy.When hepatectomy was compared with choledocholithotomy,the recurrence rate of acute cholangitis combined with bile duct stone (5.8％ vs.21.5％),the reoperation rate (5.8％ vs.21.5％),the bile duct stricture rate (8.0％ vs.44.6％),the abnormal liver parenchyma perfusion rate (4.3％ vs.23.1％),the incidence of intrahepatic bile duct enhancement or thickening (1.5％ vs.26.9％),the incidence of hepatic atrophy (3.0％ vs.30.0％) and the incidence of cholangiocarcinoma (0 vs.2.3％) were better.Conclusions The long-term adverse outcomes were significantly worse in the choledocholithotomy group than in the partial hepatectomy group.Choledocholithotomy combined with choledochoscopy should only be considered as a complementary procedure to partial hepatectomy in hepatolithiasis.
