Abstract：
OBJECTIVE: To evaluate the feasibility and application value of mixed reality technology (MR) in Primary retroperitoneal tumour (PRT) surgery.
METHODS: From 276 patients who underwent PRT resection at the First Affiliated Hospital of Xi\'an Jiaotong University, we screened 46 patients who underwent MR-assisted retroperitoneal tumour resection and 46 patients who underwent tumour resection without MR assistance. The intraoperative and postoperative recovery of the patients in both groups were compared, and the reliability and validity of the application of MR were further examined using the Likert scale.
RESULTS: There was a significant difference in the mean intraoperative bleeding volume between the two groups, but it was reduced in the MR group. The results of the Likert scale showed higher scores in the MR group than non-MR group.
CONCLUSIONS: MR can be used to assist PRT resection and has great potential to improve the rate of complete retroperitoneal tumour resection.

摘要：
目的：评价混合现实技术(MR)在原发性腹膜后肿瘤(PRT)手术中的可行性和应用价值。
方法：从西安交通大学第一附属医院接受PRT切除术的276例患者中，我们筛选了46例接受MR辅助腹膜后肿瘤切除术的患者和46例未接受MR辅助的肿瘤切除术的患者.比较两组患者术中、术后恢复情况,并使用Likert量表进一步检查MR应用的信度和效度。
结果：两组术中平均出血量有显著差异，但在MR组减少。Likert量表的结果显示，MR组的得分高于非MR组。
结论：MR可用于辅助PRT切除，并具有提高腹膜后肿瘤完全切除率的巨大潜力。
