Abstract:
Objective To evaluate the application of 64-slice computed tomography (CT) and software-assisted image analysis in preoperative evaluation and surgical planning of hilar cholangiocarcinoma. Methods The clinical data of six patients with hilar cholangiocarcinoma who were admitted to The First Affiliated Hospital of Sun Yat-sen University from June to December, 2009 were retrospectively analyzed. All six patients underwent 64-slice CT scanning before the operation, and then three-dimensional (3D) reconstruction of the liver, tumor, blood vessels and bile ducts was achieved with the assistance of Myrian (R) XP-Hepatic software. The relationships of the tumor, blood vessels and bile ducts were illustrated in the 3D model. Virtual liver resection was carried out for surgical planning. Results The 3D models of the liver, tumor, blood vessels and bile ducts were successfully constructed . The 3D models were able to be rotated and magnified as necessary. Preoperative evaluation and surgical planning were in accordance with actual surgery. The relative accuracy of the software-assisted image analysis system for calculating the hepatic volume to be resected was 5%. Patients recovered well without occurrence of hepatic failure. Conclusion Sixty-four-slice CT scanning and software-assisted image analysis are important for preoperative evaluation and surgical planning of hilar cholangiocarcinoma.
