Expert consensus of precise diagnosis and treatment for pancreatic head cancer using three-dimensional visualization technology / 中华外科杂志

Three-dimensional (3D) visualization technology in pancreatic head cancers could offer decision-making support to preoperative diagnosis, resectability assessment and individualized surgical planning. In addition, the pancreas 3D printing helps to realize the leapfrog development from 3D images to 3D physical models and provides better guidance of the precise surgery of complicated cancers of the pancreatic head. In order to standardize the application of 3D visualization and 3D printing technology in the diagnosis and treatment of pancreatic head cancer, Chinese experts in relevant fields were organized by four committees to formulate this expert consensus. This consensus give the suggestion from ten aspects on the treatment of pancreatic head cancer, such as the preoperative evaluation, acquisition method of CT data, the construction of three-dimensional visualization model, clinical classification of resectability assessment based on the 3D visualization technology, simulation surgery, 3D printing, the guidance with 3D visualization technology on pancreatic cancer surgery, intraoperative examination of resectability assessment, and the other treatment based on 3D visualization technology with pancreatic head cancer. The consensus will give the reference to the doctors who is developing or is going to develop the 3D visualization technology on pancreatic head cancer.

Classification, staging, and resectability assessment for hilar cholangiocarcinoma / 中华肝胆外科杂志

Hilar cholangiocarcinoma is a type of malignant tumor of the extrahepatic ductal system.Due to hepatic artery and portal vein involvement within the liver hilum,the resection rate is low and the prognosis is poor.However,with several advances in imaging technology achieved during the last decades,the accuracy of diagnosing and assessing the resectability of hilar cholangiocarcinoma has been greatly improved.In fact,some new classification and staging systems have been proposed to evaluate the tumor.This review will discuss the recent advances in the classification,staging,and preoperative resectability assessment for hilar cholangiocarcinoma.
