BMI Body mass index, PNM stage the classifications P (parasitic in the liver), N (extension to neighboring organs), and M (distant metastasis) were developed by the European Echinococcosis Registry Network of the WHO Informal Working Group on Echinococcosis, ERAT ex vivo liver resection and autotransplantation, PTCD percutaneous transhepatic cholangial drainage, RLV remnant liver volume (preoperative measurement by CT images). Patient 4 died 1 day after surgery, so there was no follow up. "*" refered to the pre-ERAT treatment measures, not the current admission (ERAT), and the interval was at least 2 months. Gender, age and clinical data of the patients were available
