Effect of digital three-dimensional reconstruction technique combined with indocyanine green (ICG) excretion test for precision hepatectomy in primary liver cancer.

The aim of this study was to evaluate the residual volume of liver reserve function in liver cancer patients using three-dimensional reconstruction technique (3D technology) and the indocyanine green (ICG) excretion test.A retrospective analysis was conducted, and data were collected from 90 liver cancer patients in Ganzhou People's Hospital between January 2017 and December 2021. The control group underwent preoperative resectability evaluation based on traditional two-dimensional images, whereas the experimental group underwent digital three-dimensional reconstruction technique combined with indocyanine green (ICG) excretion test. The intraoperative bleeding volume, accuracy of preoperative surgical planning, operation time, postoperative complication rate, and perioperative mortality were compared between the two groups.The assessment of resected liver volume (resectability) in the experimental group was larger than in the control group (P=0.003). Moreover, the accuracy rate of preoperative surgical planning in the experimental group was higher than in the control group (P=0.014). The intraoperative estimated blood loss favored the experimental group by a mean of 355 ml (P=0.02). Operative time and hospital stay favored the experimental group by a mean time of 204 min (P=0.03). The positive rate of liver resection margin and recurrence rate in the experimental group were lower than in the control group (P=0.021, P=0.004). Moreover, the two groups differed after intervention in terms of AST (P=0.001), ALT (P=0.0001), TBIL (P=0.001), and ALB (P=0.026).The combination of three-dimensional reconstruction technique and indocyanine green (ICG) excretion test provides accurate visualization of hepatic anatomy and improves the precision of liver resection surgery, which is of great guiding value. This can optimize the preoperative evaluation and surgical planning for liver resection, shorten the operation time, and reduce intraoperative bleeding volume.
