To explore the value of three-dimensional visualization technology in preoperative precise assessment for huge hepatic carcinoma (HCC).

The clinical data of twenty-five patients with giant HCC who were admitted to Chenggong Hospital Affiliated to Xiamen University from January 2013 to January 2015 were retrospectively analyzed. Based on simulated hepatectomy and three-dimensional visualization technology, the two-dimensional images of CT were converted into three-dimensional images. Preoperative assessment was done by measuring the volume of liver, tumor, pre-resection liver and residual liver. For patients undergoing operation, volume of the predicted resected liver and the results of the actual liver resection was calculated for a correlation test analysis.

All the liver tissues, tumor tissues and the hepatic vessels were reconstructed successfully using the three-dimensional reconstruction software. Twenty patients underwent accurate assessment followed by precise operation. The volume of simulated resected liver was (1 856.10±255.85) ml, while the actual liver resection volume was (1 817.02±251.17) ml. There was no significant difference between the predicted and the actual values (t=0.487, P>0.05). The actual liver resection volume was positively correlated with the predicted liver resection volume (r=0.972, P<0.05).

The three-dimensional visualization technology has a certain degree of clinical value in the precision before giant hepatocellular carcinoma surgery.
