三维模拟技术在精准肝脏切除中的应用

目的 评价三维模拟技术在精准肝脏切除中的应用价值.方法 自2009年7月至2010年5月,本院对16例手术治疗的原发性肝癌患者,于术前进行了三维模拟成像及模拟手术操作,并对二者切除的肝脏组织在三维径线上的绝对长度进行统计学分析.结果 模拟手术切除的肝脏组织形状及大小与实际手术切除的非常相似,两者肝脏切除边缘长度明显相关,而且没有统计学差异(P＞0.05).模拟手术与实际手术两者切除肝脏在长度、宽度和高度上的差值分别为0.6118 cm、0.4490 cm和0.3199 cm.结论 三维模拟技术可以准确预测目标病灶的切除范围,为精准肝脏切除提供术前指导.

Abstract：

Objective To study the application of three-dimensional simulated surgical technique in precise hepatectomy. Methods From July 2009 to February 2010, 16 patients with primary liver cancer underwent preoperative simulated imaging and three-dimensional simulation of liver resection.The 3D extent of simulated hepatectomy and actual hepatectomy was compared and analyzed. Results The shape and the extent of the liver resected were very similar in the simulated and the actual hepatectomies. The mean differences in the length, breadth and depth of the remnant livers were 0. 6118 cm,0. 4490 cm and 0. 3199 cm, respectively. Conclusions Simulation hepatectomy could predict the extent of the actual liver resection, and provided accurate guidance and preoperative planning for precise hepatectomy.
