摘要
目的探究肝脏三维重建技术在泡型肝包虫病术前评估中的意义。方法搜集青海大学附属医院肝胆胰外科2013年1月至2014年3月期间住院治疗的泡型肝包虫病患者的肝脏三期动态薄层CT扫描图像,以DICOM格式导入数字化肝脏三维重建软件,行三维模拟成像操作,计算参数,设计虚拟手术方案,手术切除病灶,称量实际切除的肝脏组织体积(实际切除肝脏体积以"1 g=1 m L"计算)。计算模拟手术切除肝脏组织体积与实际切除肝脏组织体积之间的相关系数r,并绘制XY散点图,分析虚拟手术欲切除肝脏体积与术中实际切除肝脏体积的相关性。结果对21例行肝脏切除术患者进行虚拟手术设计,虚拟手术欲切除肝脏体积为(761.94±505.77)m L,欲切除肝脏体积占全肝脏体积的(39.27±18.75)%;术中实际切除肝脏体积为(756.19±501.78)m L,手术切除肝脏体积占全肝脏体积的(38.95±16.99)%。虚拟手术欲切除肝脏体积与术中实际切除肝脏体积比较差异无统计学意义(P>0.05),且二者呈高度正相关(r=0.989,P<0.001)。结论从本研究有限的数据初步得出,肝脏三维重建技术及虚拟手术规划系统可精确指导病灶切除范围,为精准肝脏切除提供术前指导。
Objective To explore potential value of three-dimensional reconstruction technique for preoperative evaluation of hepatic alveolar echinococcosis. Methods Twenty-one cases of hepatic alveolar echinococcosis proved by postoperative pathological examination in Affiliated Hospital of Qinghai University from October 2013 to March 2014 were analyzed retrospectively. The three periods of patients＇ liver dynamic thin layer CT scan images were collected and imported in three-dimensional reconstruction software by DICOM format. The volume of the virtual resected liver tissue was calculated by software, and then was compared with the actual resected liver tissue volume. Results The resected liver volume was（761.94±505.77） mL and（756.19±501.78） mL in the virtual surgery and in the veritable surgery, respectively.The proportion of resected liver in the total liver was（39.27±18.75）% and（38.95±16.99）% in the virtual surgery and in the veritable surgery, respectively. The resected liver volume had no significant difference between the virtual surgery and veritable surgery（P〈0.05）, which a positive relation（r=0.989,P〈0.001）. Conclusion The limited preliminary data in this study show that three-dimensional reconstruction technique and virtual planning system for surgery could accurately guide resection of lesion and provide preoperative guidance of accurate liver resection for hepatic alveolar echinococcosis.
