Clinical Application Of Three-dimensional Reconstruction Techniques On Precise Hepatectomy

Objective To explore the clinical applications of three-dimensional reconstruction technique on precise hepatectomy for primary liver cancer.Methods Our hospital introduced 3D virtual surgical planning system(IQQA-Liver), which can be applied clinically on precise hepatectomy. Collecting 53 cases of patients with primary liver cancer before applying three-dimensional reconstruction technique and 39 cases after applying the technique, which were divided into group A and group B. Group A of hospital surgery was implemented before introduceing three-dimensional reconstruction technology, so the design and planning of the operation and the specific implementation were based on the traditional two-dimensional image data. This group analysed intraoperative and postoperative conditions such as operation time, blood loss, complications, which was compared with group B; Group B took two-dimensional and three-dimensional measures to measure total liver volume, pre-cut volume, and then making an operation based on resection assessed of three-dimensional reconstruction technology.Results(1) Based on the statistical analysis of postoperative complications on the two groups, the complications of B group was loss than A, but no significant difference. It was at least showed that the results of implementation of the three-dimensional reconstruction on the line precision hepatectomy was not worse than two-dimensional preoperative planning’s.(2) No significant difference(t=1.985, P>0.05) was found in the calculation of resected liver volume between the implementation of three-dimensional and two-dimensional.Conclusion Three-dimensional reconstruction techniques can achieve certainty, predictability, controllability goals of precise hepatectomy.
