Research background

As a new digital holographic imaging technology, mixed reality (MR) it has been preliminarily applied in hepatectomy for hepatocellular carcinoma (HCC). In this study, 95 patients with HCC who underwent hepatectomy were retrospectively analyzed to evaluate the application value of MR.

Research motivation

MR has been gradually applied to neurosurgery, orthopedics, and urology with an improvement in perioperative outcomes. MR may also have great potential in hepatectomy by preoperative planning and intraoperative navigation.

Research objectives

The aim of this study was to explore the application value of MR technology in hepatectomy for HCC.

Research methods

Total 95 patients with HCC were enrolled in the study, including 38 patients who underwent MR-assisted hepatectomy in Group A and 57 patients who underwent hepatectomy with traditional methods in Group B. Perioperative variables of the two groups of patients were collected and compared.

Research results

MR-assisted hepatectomy could significantly reduce the operation time, obstructive time of the portal vein, and the volume of bleeding. And the recovery of alanine aminotransferas and albumin in patients with MR-assisted hepatectomy was faster.

Research conclusions

MR significantly improved the perioperative outcomes of hepatectomy for HCC.

Research perspectives

MR may also have a certain application potential for laparoscopic and robotic hepatectomy, and it will be explored in future.
