Three-dimensional (3D) printed models based on computed tomography (CT) images facilitate the visualization of complex structures and are useful for understanding the surgical anatomy preoperatively. We developed a preoperative surgical simulation method using a 3D printed model based on CT images obtained prior to laparoscopic adrenalectomy for adrenal neuroblastomas (NBs).
The multi-detector CT images were transferred to a 3D workstation, and 3D volume data were obtained by reconstructing the sections. A model was made with a 3D printer using acrylic ultraviolet curable resin. The adrenal tumor, kidney, renal vein and artery, inferior vena cava, aorta, and outer body were fabricated. The pneumoperitoneum, insertion of trocars, and laparoscopic view were all attainable in this model. We used this model for three cases with adrenal NB.
We used this model to discuss the port layout before the operation and to simulate the laparoscopic view and range of forceps movement. All three cases with NB were completely resected without any surgical complications.
The surgical simulation using 3D printed models based on preoperative CT images for adrenal NB was very useful for understanding the patient's surgical anatomy and for planning the surgical procedures, especially for determining the optimal port layout.
基于计算机断层扫描（CT）图像的三维（3D）打印模型有助于复杂结构的可视化，对于术前了解手术解剖结构很有用。我们开发了一种术前手术模拟方法，该方法使用基于肾上腺神经母细胞瘤（NB）腹腔镜肾上腺切除术之前获得的CT图像的3D打印模型。
将多探测器CT图像传输到3D工作站，并通过重建切片获得3D体积数据。使用丙烯酸紫外光固化树脂通过3D打印机制作模型。制作出肾上腺肿瘤、肾脏、肾静脉和动脉、下腔静脉、主动脉以及身体外部。在该模型中可以实现气腹、套管针插入以及腹腔镜视野。我们将此模型用于3例肾上腺NB患者。
我们使用该模型在术前讨论端口布局，并模拟腹腔镜视野和钳子移动范围。所有3例NB患者均完全切除，无任何手术并发症。
基于术前CT图像的3D打印模型进行手术模拟对于了解患者的手术解剖结构和规划手术程序非常有用，特别是对于确定最佳端口布局。
