“… 79 , 80 Moreover, the use of a virtual 3D reconstruction model created by multidetector CT and prototyped using a 3D printer was proposed for a better preoperative understanding of the surgical liver anatomy and surgical resection planning. 81 A prospective trial assessing the impact of 3D reconstruction on surgical planning is actually ongoing (3D HAPPI Trial IRCAD).…”

Liver resection is one of the main curative options for early hepatocellular carcinoma (HCC) in patients with cirrhosis and is the treatment of choice in non-cirrhotic patients. However, careful patient selection is required to balance the risk of postoperative liver failure and the potential benefit on long-term outcomes. In the last decades, improved surgical techniques and perioperative management, as well as better patient selection, have enabled the indications for liver resection to be expanded. In this review, we aim to describe the main indications for liver resection in the management of HCC, its role compared to percutaneous ablation and liver transplantation in the therapeutic algorithm, as well as the recent advances in liver surgery that could be used to improve the prognosis of patients with HCC.

“…Both student education in liver anatomy and resident training in liver surgical techniques with the use of 3D printed models are the second most widely studied application. Ten studies refer to this field, five of which were designed as case reports or case series[28,32,37,38,41], one was an observational cohort study[34] and four were RCTs[35,36,39,40]. The case reports and case series state that 3D printed models could help in both the understanding of liver anatomy and surgical training, but fail to provide objective evidence.…”

“…This may be attributed to the small sample size that may not have supported safe comparison tests. Two RCTs were published in 2016[35,36], and two in 2018[39,40], comparing the educational impact of 3D printing to more conventional strategies. Kong et al[34] randomized 61 medical students into three cohorts: the 1 st was trained in 3D printed models, the 2 nd in 3D virtual models on computers and the 3 rd in traditional anatomy atlases.…”

“…Although the randomized sample was also small, the design was sophisticated, and the results showed 3D printed models to be superior. Yang et al[39] evaluated the educational impact of 3D printed models against 3D virtual models and CT-based tools, and found them to be superior. These studies provide significant evidence that 3D printing could be applied in education and training in liver surgery, although they may have some methodological weaknesses.…”

Three-dimensional (3D) printing has recently emerged as a new technique in various liver-related surgical fields. There are currently only a few systematic reviews that summarize the evidence of its impact. In order to construct a systematic literature review of the applications and effects of 3D printing in liver surgery, we searched the PubMed, Embase and ScienceDirect databases for relevant titles, according to the PRISMA statement guidelines. We retrieved 162 titles, of which 32 met the inclusion criteria and are reported. The leading application of 3D printing in liver surgery is for preoperative planning. 3D printing techniques seem to be beneficial for preoperative planning and educational tools, despite their cost and time requirements, but this conclusion must be confirmed by additional randomized controlled trials.

“…The 3-D printing of organs and structures has proved valuable for multiple disciplines within the engineering field and clinical practice, such as urology, neurosurgery, cardiac surgery, plastic surgery, and maxillofacial surgery. 12 , 13 , 14 , However, 3-D printing is not the current standard of care. In addition, augmented reality (AR) is a technology that can visualize virtual 3-D objects in the real world.…”

Comparison of 3-Dimensional and Augmented Reality Kidney Models With Conventional Imaging Data in the Preoperative Assessment of Children With Wilms Tumors

Key Points Question What is the value of 3-dimensional (3-D) visualization methods, augmented reality holograms, and 3-D printing for the preoperative assessment of anatomical structures in children with Wilms tumors? Findings In this survey study of 7 pediatric surgeons for which 10 personalized, augmented reality holograms and 3-D prints of children with Wilms tumors were created, there was a significant added value from the 3-D visualization methods compared with conventional imaging for the preoperative assessment. Meaning Three-dimensional visualizations may provide added value for the pediatric surgeon in the anatomical assessment of Wilms tumors, may help in future preoperative planning of nephron-sparing surgery, and may be considered an innovative supplementary visualization in clinical care.
