Objective:To study the surgical experience with resection of a hilar liver cancer close to major vessels and how to improve the therapeutic result. Methods:From January 1990 to June 1997,58 hilar liver tumors(segmentⅠ,Ⅳ,Ⅴ,Ⅷ) ere resected.The tumors in these 58 patients were within a distance of 1 com to major hepaitc vessels(retrothepatic inferior vena cava,root of hepatic veins,and left or right trunk of portal vein).The diameter of the tumors was＞5cm in 42cases and ＜5 cm in 16cases,respectively.The size of the largest tumor was 20cm×18cm×18cm.The surgical techniques are summarized,and the prevention and treatment of postoperative complications are discussed. Results:All operations have been carried out successfully and had a regular follow-up until now with 1-,3-and 5-year survival rate of 71%,38% and 25%,respectively. Conclusion:While hilar liver surgery is quite difficult and risky,the safety and therapeutic results of surgery could be improved by observing a meticulous surgical technique,and by preventing and treating postoperative complications by multimodal measures.
