OBJECTIVE To explore the utility of three-dimensional (3D) visualization technology in liver resection for patients with complex liver cancer. METHODS In this retrospective cohort study, we collected and analyzed clinic pathological data from 105 patients who underwent complicated liver cancer resection at the authors' unit between January 2014 and June 2019. Observation indicators included general demographic information, operative time, intraoperative blood loss, blood transfusion volume, postoperative liver function, complication rate, hospital stay, and in-hospital mortality. RESULTS Compared with the complex liver cancer control group, operative time (257.1  ±  63.4 min versus [vs] 326.6  ±  78.3 min; P < 0.001), intraoperative blood loss (256.4  ±  159.1 mL vs 436.1  ±  177.3 mL; P < 0.001), blood transfusion volume (213.3  ±  185.2 mL vs 401.6  ±  211.2 mL; P < 0.001), and length of hospital stay (9.7  ±  3.1 days vs 11.9  ±  3.3 days; P = 0.001) were significantly reduced in the complex liver cancer reconstruction group. Although there was no statistical difference in total postoperative complication rate between the two groups, the incidence of serious postoperative complications in the reconstruction group was significantly lower than that in the control group (3/54 [5.6%] vs 10/51 [19.6%], respectively; P = 0.038). Regarding laboratory investigations, the time to recovery of liver function in the complex liver cancer reconstruction group was shorter than that in the complex liver cancer control group. CONCLUSION The use of 3D visualization technology was highly influential in formulating meticulous, individualized surgical strategies for complex liver cancer liver resection with safety and reduced perioperative risk.

三维重建技术在复杂肝癌切除中的临床应用

目的探讨三维（3D）可视化技术在复杂肝癌肝切除术中的应用。方法 在这项回顾性队列研究中，我们收集并分析了 2014 年 1 月至 2019 年 6 月在作者单位接受复杂肝癌切除术的 105 例患者的临床病理资料。观察指标包括一般人口学信息、手术时间、术中失血量、血输血量、术后肝功能、并发症发生率、住院时间和住院死亡率。结果 与复杂肝癌对照组相比，手术时间（257.1 ± 63.4 min vs [vs] 326.6 ± 78.3 min；P < 0.001），术中失血量（256.4 ± 159.1 mL vs 436.1 ± 177.3 mL； P < 0.001），输血量 (213. 3 ± 185.2 毫升与 401.6 ± 211.2 毫升；P < 0.001）和住院时间（9.7 ± 3.1 天 vs 11.9 ± 3.3 天；P = 0.001）在复杂肝癌重建组中显着减少。虽然两组术后总并发症发生率无统计学差异，但重建组术后严重并发症发生率明显低于对照组（3/54 [5.6%] vs 10/51 [19.6%] ]，分别；P = 0.038)。在实验室检查方面，复杂肝癌重建组肝功能恢复时间短于复杂肝癌对照组。结论 3D可视化技术的使用对制定细致、
