To evaluate 3D visualization technology in the preoperative planning of hepatic malignancy surgery.

The clinical data of 42 patients with hepatic malignancy undergoing radical resection after 3D reconstruction assessment from Feb 2015 to Feb 2018 in our center was retrospectively studied . The predicted resected liver volume were compared with that of resected specimen.

Surgery was successful in all the 42 patients , and there were no operative deaths. The average operation time was (303±109 ) minutes, the average intraoperative blood loss was (510±482) ml, and 28 patients had intraoperative hepatic inflew occlusion. Postoperative Clavien Ⅲ complications occurred in 4 cases. In terms of the resection liver volume, there was no significant difference between the predicted results (PELV) and actual results [resection liver volume(AELV): (1 143±584)ml vs. (1 091±570 )ml, t=0.414, P>0.05]. There is a strong positive correlation between AELV and PELV (r=0.996, P<0.01). PELV was highly consistent with AELV data (ICC=0.998).

Three-dimensional visualization technology can accurately reflect the anatomic relationship between intrahepatic tumors and vessels, and correctly assess liver volume, guide surgical resection, thus, it can instruct radical resection of liver malignancy.
