The aim of the multi-centre study is to evaluate correctly the impact of three dimensional visualization on operation strategy and complications for complex hepatic carcinoma.

Because of the complexity of complex hepatic carcinoma,the limitations of 2D images of CT/MRI and the uncertainty of surgeons'experience, it is difficult for the surgeons to diagnosis and assess the operation strategy accurately based on traditional 2D imaging(CT/MRI).The aim of the multi-centre study is to evaluate correctly the impact of three-dimensional visualization on operation strategy and complications for complex hepatic carcinoma.

Inclusion Criteria:

1. 18 years≤ Age ≤70 years
2. Compling with the diagnosis criteria of complex hepatic carcinoma.
3. Primary hepatic carcinoma without intrahepatic or extrahepatic extensive cancer metastasis, the metastatic hepatic carcinoma whose primary focal has been controlled
4. Preoperative liver function is Child - Pugh grade A or B.
5. The patients are volunteered for the study.

Exclusion Criteria:

1. Patients with mental illness.
2. Patients can't tolerate the operation owe to a variety of basic diseases (such as severe cardiopulmonary insufficiency, renal insufficiency, cachexia and blood system diseases, etc.)
3. The patients refused to take part in the study.
4. There are other co-existed malignant tumors.
5. Benign liver diseases.
