Detailed Description
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.
Study Design
Outcome Measures
Primary Outcome Measures
- Impact on operation strategy of three-dimensional visualization technique [2 year]
Firstly, the operation strategies based on original CT or MRI image data will be made by the team, Secondly, the operation strategies based on three dimensional reconstruction models will be made by the team, then, actually surgical strategies will be recorded. The change of operation strategy will be assessed by comparing the strategy of the 2D model and 3D model. The change rate of operation strategy will be recorded and presented as percentage.
- Impact on complications of three-dimensional visualization technique [2 year]
The complications are refer to the classification of Clavien-Dindo, including postoperative bleeding, biliary fistula, ascites, postoperative liver failure, renal dysfunction, pleural effusion, abdominal cavity infection, abdominal abscess, incision infection, the occurrence cases of each complications (number) will be recorded.
