[Clinical application of precise liver resection techniques in patients with complicated liver space-occupying lesions].

OBJECTIVE
To evaluate the early results of precise liver resection.


METHODS
Between May 2006 and June 2009, 65 patients with complicated liver space-occupying lesions were included in the study. Fifty-one patients underwent curative liver resection. Liver resections performed included 16 trisectionectomies, 11 hemihepatectomy, 5 meso hepatectomies, 3 combined segmentectomies, 5 caudate lobectomies and 11 irregular local resections.


RESULTS
Patients undergoing resection had no mortality with a major morbidity of 9.8%. Nineteen vascular repairs and reconstructions were patent at last follow-up. The postoperative 1-year survival rate was 100% in 10 patients with benign lesions and 92.7% in 41 patients with malignant tumors. The 1-year survival rate was zero in patients with malignant tumors, who underwent no liver resection.


CONCLUSIONS
Precise liver resection, as an aggressive surgical approach, offers hope for these patients, who would otherwise have a dismal prognosis.
