14Over the past decade, improvements in preoperative liver function assessment and multidisciplinary treatments have extended the indications for hepatic resection to includelarger tumours, multiple foci of disease and bilobar disease. These treatments include liver augmentation strategies such as portal vein embolization6,7 and associating liver partition with portal vein ligation for staged hepatectomy8, or tumour burden-reducing strategies such as systemic or hepatic arterial chemotherapy9 and ablative therapies10

16The present CRA results were compared with datafor TSR reported recently by Tsai et al.19,Wicherts and colleagues18 and Brouquet and co-workers17 (Table 3). Overall, therewas a total of 141 patients in theTSRcohort, of whom 123 eventually completed the second-stage hep- atectomy for bilobar lesions. The
he com-binedmorbidity rate of both procedures in the TSR group was compared with the complication rate for CRA; based on this comparison, the complication rate for the TSR group was significantly higher: 631 per cent (89 of 141) versus 317 per cent (32 of 101) (P
