Objective: The effectiveness of liver transplantation depends on a correct segmentation of the donor's liver volume, particularly in the case of split and living donor liver transplants. In this study, we used the Hisense Computer-Assisted Surgery System (Hisense CAS) to precisely design the surgery and assess the divided liver’s volume.
Method: We used Hisense CAS to reconstruct the donor liver based on the preoperative enhanced CT images and were able to intuitively design 3D graphics of donor liver volume. After that, the volume of the divided liver-which included the right three lobes, left lateral lobe, left half, and right half-was measured. This measurement was then compared and examined with the real volume that was taken during surgery. Simultaneously, we also acquired the post-operative changes in liver volume regeneration using the Hisense CAS.
Results：
1. We were able to effectively generate 3D pictures of the donor liver, hepatic vein, portal vein, artery, and biliary system from 62 donors and 80 recipients.
2. The preoperative assessment volume and the intraoperative measurement volume were compared and statistically analyzed for split and living donors, including left lateral lobe 28 cases (Living donor 15 cases, DBD 13 cases), right three lobes 21 cases (DBD 21 cases), left half 13 cases (Living donor 6 cases, DBD 7 cases) and right half 18 cases (Living donor 11 cases, DBD 7 cases). There was no statistically significant difference among the groups.
3. Following split and living donor liver transplantation, the donor liver volume was monitored, and the results showed that one month following transplantation, the donor liver volume had reached the standard liver volume.
Conclusion: Our results shown that the donor liver's volume may be precisely determined using Hisense CAS. There was no statistically significant discrepancy between the reconstructive assessment of the donor liver volume and the actual measured volume after surgery. Hisense CAS therefore offers excellent clinical application value.
