Application of medical 3Dv (three-dimensional visualization) technology in liver surgery
医学3DV（三维可视化）技术在肝脏外科精准手术中的应用研究

摘要

目的 探讨医学3DV（三维可视化）技术在肝脏外科精准手术中的应用研究。方法 选取我院2020年1月-2021年1月进行肝脏外科精准手术的数据资料112例，分为对照组和观察组各56例，对照组为MRT二维影像进行手术设计，观察组为三维可视化技术进行术前评估及手术设计，比较分析两组术后相关情况。结果 观察组没有出现结石残留情况，两组炎症复发情况差异无统计学意义。观察组结石、胆管情况整体优于对照组，差异具有统计学意义（P＜0.05）。两组患者术后住院时间差异无统计学意义（P＞0.05），观察组引流管拔出时间和肛门排气均少于对照组，差异具有统计学意义（P＜0.05）。观察组并发症情况显著低于对照组，差异具有统计学意义（P＜0.05）。对照组患者出现4例切口感染、5例肝脓肿现象，与观察组相比发生率较高，但差异无统计学意义（P＞0.05）。结论 三维可视化技术与传统的CT或MRI相比，更具有实用价值。三维可视化技术应用于肝脏外科手术，可减少术后并发症，具有更低的副作用，以及良好的预后。

Abstract

Objective To explore the application of medical 3DV (three-dimensional visualization) technology in precise liver surgery.
Methods Selected the data of 112 cases of liver surgery precision surgery in our hospital from January 2020 to January 2021, and divided them into control group and observation group with 56 cases in each. Three-dimensional visualization technology was used for preoperative evaluation and surgical design, and the postoperative related conditions of the two groups were compared and analyzed.
Results There was no residual stone in the observation group, and there was no significant difference in the recurrence of inflammation between the two groups. The conditions of stones and bile ducts in the observation group were better than those in the control group, and the difference was statistically significant (P<0.05). There was no significant difference in postoperative hospital stay between the two groups (P>0.05). The drainage tube pull-out time and anal exhaust in the observation group were shorter than those in the control group, and the difference was statistically significant (P<0.05). The complications in the observation group were significantly lower than those in the control group, and the difference was statistically significant (P<0.05). There were 4 cases of incision infection and 5 cases of liver abscess in the control group, which were higher than those in the observation group, but the difference was not statistically significant (P>0.05).
Conclusion   3D visualization technology has more practical value than traditional CT or MRI. Three-dimensional visualization technology applied to liver surgery can reduce postoperative complications, have lower side effects, and a good prognosis.
