- Abstract:
- Abstract: Objective To explore the application value of liver volume assessment and three-dimensional (3D) visualization based on 3D reconstruction system software and 3D printing-assisted major hepatectomy for liver cancer. Methods Forty-six liver cancer patients scheduled for major hepatectomy were randomly divided into observation group and control group, with 23 cases in each group. 3D visualization technique and 3D printing model were adopted in observation group (3D group) for perioperative planning and guidance which mainly included preoperative planning and 3D visualization analysis based on liver volume assessment and 3D printing-guided liver resection. In control group (CT group), the traditional CT data were used for preoperative planning of liver volume assessment, and the liver resection was guided by two-dimensional CT image data. The observation indexes contained virtual liver resection volume, actual liver resection volume, residual liver volume, standard residual liver volume ratio, operation time, intraoperative blood loss, postoperative complications and patients satisfaction. Results In 3D group and CT group, there were no statistically significant difference in the comparison between virtual liver resection volume and actual liver resection volume, and the comparison between virtual (preoperative) residual liver volume and the actual (postoperative) residual liver volume (P>0.05). There were positive correlations between virtual liver resection volume and actual liver resection volume (r=0.990, P<0.001 in 3D group r=0.943, P<0.001 in CT group). There was no statistically significant difference between virtual residual liver volume ratio and actual residual liver volume ratio in both 3D group and CT group (P>0.05), and there were significant positive correlations between them (r=0.972, P<0.001 in 3D group r=0.931, P<0.001 in CT group). The intraoperative blood loss in 3D group was less than that in CT group (P<0.05), and the patients satisfaction in 3D group was better than that in CT group (P<0.05). No statistical difference was found between two groups in operation time and postoperative complications (P>0.05). Conclusion The use of 3D reconstruction system software and CT software in evaluating the liver volume in major hepatectomy for liver cancer is proved to be effective and accurate, which have good clinical application value and are helpful for the implementation of liver resection. 3D visualization combined with 3D printing can reduce surgical bleeding in perioperative planning and improve patients satisfaction, with potential advantages in clinical application.
