“…Further studies with the inclusion of more participants, especially novice surgeons, are needed to validate the clinical value of 3D-printed pancreatic models in preoperative planning or skill improvement. Our preliminary findings are consistent with others [ 80 , 81 ], although future studies should include more cases and participants to allow robust conclusions to be drawn.…”

“…The significant discrepancy in measurements could be due to inconsistencies among the orientation and location of anatomical landmarks between post-processed data (STL file) and 3D-printed physical models and this needs to be considered in future studies [ 82 ]. The large discrepancy was also reported by Bati et al, with significant differences in dimensional measurements between 3D STL images and the original images/images of the 3D-printed model [ 80 ]. A 3D-printed model of the biliary system can be used for education and training, as well as the treatment of complex biliary disease [ 83 , 84 ].…”

“…The use of 3D printing in pancreaticobiliary disease is only reported in a few case studies with results showing that 3D-printed models improve the outcome of pancreaticobiliary surgeries by enhancing the understanding of the operation process and serving as a training tool [ 5 , 20 , 80 , 81 ]. We printed a pancreatic cancer model along with abdominal aorta and main arterial branches and also created VR views for comparison with 3D-printed models with regard to their value in the preoperative planning of pancreatic tumours ( Figure 20 ).…”

3D printing has been increasingly used for medical applications with studies reporting its value, ranging from medical education to pre-surgical planning and simulation, assisting doctor–patient communication or communication with clinicians, and the development of optimal computed tomography (CT) imaging protocols. This article presents our experience of utilising a 3D-printing facility to print a range of patient-specific low-cost models for medical applications. These models include personalized models in cardiovascular disease (from congenital heart disease to aortic aneurysm, aortic dissection and coronary artery disease) and tumours (lung cancer, pancreatic cancer and biliary disease) based on CT data. Furthermore, we designed and developed novel 3D-printed models, including a 3D-printed breast model for the simulation of breast cancer magnetic resonance imaging (MRI), and calcified coronary plaques for the simulation of extensive calcifications in the coronary arteries. Most of these 3D-printed models were scanned with CT (except for the breast model which was scanned using MRI) for investigation of their educational and clinical value, with promising results achieved. The models were confirmed to be highly accurate in replicating both anatomy and pathology in different body regions with affordable costs. Our experience of producing low-cost and affordable 3D-printed models highlights the feasibility of utilizing 3D-printing technology in medical education and clinical practice.

“…In cancer surgery, a clear understanding of the target anatomy (size, margin and neighborhood volume) should be obtained in the preoperative setting with planning the operation accordingly [10,11]. Algorithm landmarks in the oncological surgical approaches of other branches such as orthopedics, plastic and reconstructive surgery are xed and unchanging guide points like bone [12,13].…”

Surgical treatment of gliomas requires an intervention that does not leave residual tumor tissue in the brain and preserves functional centers. Although orientation parameters are not present in the traditional-MRI navigation information calculated from MRI, poor mans are observed for the neuro-oncological surgery in most parts of the world. The aim of this study is to obtain instant personalized neuro-navigational information through a 3D-patient-specific model to perform functional resection of the brain. 20 patients diagnosed with gliomas were included in this study. Neuro-oncological navigation calculations of 10 patients were carried out with traditional-MRI support and the remaining 10 with the 3D-model. In this way, the actual size of the tumor, its distance from cortical structures, and perioperative surgical planning were made by the 20 neurosurgeons based on the patient-specific model. They were required to compare their perception level of the cases with traditional-MR and 3D-models in terms of identifying the invasion of the mass, making the proximity to functional centers and anatomical structures as part of perioperative planning. All neurosurgeons have given higher scores for 3D-model supported neuro-navigations. 80–90% of them preferred the model in preoperative planning as they are beneficial in anticipating determining and envisaging the entire process of the functional resection covering the location and extent of craniotomy, the extent of tumor resection on functional areas. For this, orientation parameters of the neuro-navigation information such as tumor size, margin size of surgical resection, presence of functional areas in the gyrus/sulcus where the tumor is located, proximity of the tumor, anatomical structures as (ventricles, arteries, veins, myelinated pathways, capsula interna, basal ganglia) should be included. It also target the perioperative advantages of 3D supported neuro-navigational information over the traditional method.

“…Recent studies have demonstrated that patient-specific 3D-printed models allow visualization of complex structures and can help develop the comprehension of pathoanatomical variations and lead to improved surgical planning. 4 5 The 3D models can be easily printed from various imaging modalities. Magnetic resonance images (MRI), computed tomography (CT) scans, as well as rotational fluoroscopy cloacagram images, can be used to perform reliable reconstructions of the affected organs.…”

Cysto-Vaginoscopy of a 3D-Printed Cloaca Model: A Step toward Personalized Noninvasive Preoperative Assessment in Patients with Complex Anorectal Malformations

et al. 2021

Introduction For the classification of the complexity of cloacal malformations and the decision on the operative approach, an exact anatomical assessment is mandatory. To benefit from using three-dimensional (3D)-printed models in preoperative planning and training, the practicability of these models should be guaranteed. The aim of this study was to evaluate the quality and feasibility of a real-size 3D-printed cloaca model for the purpose of cysto-vaginoscopic evaluation. Materials and Methods We performed a 3D reconstruction and printed a real-size, rubber-like 3D model of an infant pelvis with a cloacal malformation and asked invited pediatric surgeons and pediatric urologists to perform a cysto-vaginoscopy on the model and to complete a brief questionnaire to rate the quality and feasibility of the model and to indicate whether they would recommend the model for preoperative planning and training. Results Overall, 41 participants rated the model quality as good to very good (M = 3.28, standard deviation [SD] = 0.50, on a scale from 1 to 4). The model was rated as feasible for preoperative training (M = 4.10, SD = 0.75, on a scale from 1 to 5) and most participants (85.4%) would recommend the model for preoperative training. The cysto-vaginoscopy of the model was considered as a valid training tool for real-life cases and improved the confidence on the anatomy of a cloaca. Conclusion The results of our study indicate that patient-specific 3D-printed models might be a useful tool in the preoperative evaluation of complex anorectal malformations by simulation of cysto-vaginoscopy with an excellent view on anatomical structures to assess the whole spectrum of the individual cloacal malformation. Our model might be a valuable add-on tool for specialty training in pediatric colorectal surgery.
