Impact of Three-dimensional Visualization on Operation Strategy and Complications for Hilar Cholangiocarcinoma

Impact of Three-dimensional Visualization on Operation Strategy and Complications for Hilar Cholangiocarcinoma

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

Because of the complexity of hilar cholangiocarcinoma,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 hilar cholangiocarcinoma.

Inclusion Criteria:

1. 18 years≤ Age ≤70 years
2. Complying with the diagnosis criteria of hilar cholangiocarcinoma.
3. Without intrahepatic or extrahepatic extensive cancer metastasis.
4. Preoperative serum bilirubin ≤51.3 umol/L or preoperative serum bilirubin < 200 umol/L after the drainage by PTCD(percutaneous transhepaticcholangial drainage)/ENBD(endoscopic nasobiliary drainage).
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.
