There was neither operative death noruncontrollable massive bleeding or air embolism oc-curred in our patients. The bleedings from the mainand short hepatic veins and right adrenal veins wereproperly managed during the operation, with a meanintraoperative blood loss of 1400 ml. Of the 68tumors resected, 65 were hepatocellular carcinomas(HCC). Their 1-, 2-, 3- and 4-year suvival rateswere 64.11%, 52. 82%, 44.90% and 36.98%, re-spectively, and the patients with HCC with capsulessurvived significantly longer than those with HCCwithout capsules.Conclusions: The liver tumors involving the hepato-caval confluence could be safely resected simply un-der PTC, without routine use of total hepatic vascu-lar exclusion. As for HCCs in this area, the tumorwith capsule is a better indicator for surgical resec-tion than that without capsule.展开更多
