“…All parameters for the hydrogel rectal spacer and no shield treatment arms were estimated from SpacerOAR trial and other published literature (Table S1, Supporting Information). [ 38–58 ] The model was partially based off a previously published model. [ 44 ] Base‐case probabilities of developing radiation proctitis in the radioprotective rectal device treatment arm were estimated assuming the personalized radioprotectant rectal device would be 75% as effective as the hydrogel spacer.…”

Personalized Radiation Attenuating Materials for Gastrointestinal Mucosal Protection

Cancer patients undergoing therapeutic radiation routinely develop injury of the adjacent gastrointestinal (GI) tract mucosa due to treatment. To reduce radiation dose to critical GI structures including the rectum and oral mucosa, 3D‐printed GI radioprotective devices composed of high‐Z materials are generated from patient CT scans. In a radiation proctitis rat model, a significant reduction in crypt injury is demonstrated with the device compared to without (p < 0.0087). Optimal device placement for radiation attenuation is further confirmed in a swine model. Dosimetric modeling in oral cavity cancer patients demonstrates a 30% radiation dose reduction to the normal buccal mucosa and a 15.2% dose reduction in the rectum for prostate cancer patients with the radioprotectant material in place compared to without. Finally, it is found that the rectal radioprotectant device is more cost‐effective compared to a hydrogel rectal spacer. Taken together, these data suggest that personalized radioprotectant devices may be used to reduce GI tissue injury in cancer patients undergoing therapeutic radiation.

“…Thus, 3D printing may be used in many different areas of operative planning and surgical training among obstetricians and gynecologists, including the planning of a complicated cesarean delivery [ 119 ], surgical planning for placenta accreta, treatment planning for cervical and endometrial cancer, and surgery for Mullerian anomalies and other benign gynecologic surgeries [ 111 , 119 , 120 , 121 ]. For instance, the knowledge of individual anatomy and pathology of the uterine cavity may essentially assist with fetal delivery from the myomatous uterus [ 119 ].…”

Medicine is a rapidly-evolving discipline, with progress picking up pace with each passing decade. This constant evolution results in the introduction of new tools and methods, which in turn occasionally leads to paradigm shifts across the affected medical fields. The following review attempts to showcase how 3D printing has begun to reshape and improve processes across various medical specialties and where it has the potential to make a significant impact. The current state-of-the-art, as well as real-life clinical applications of 3D printing, are reflected in the perspectives of specialists practicing in the selected disciplines, with a focus on pre-procedural planning, simulation (rehearsal) of non-routine procedures, and on medical education and training. A review of the latest multidisciplinary literature on the subject offers a general summary of the advances enabled by 3D printing. Numerous advantages and applications were found, such as gaining better insight into patient-specific anatomy, better pre-operative planning, mock simulated surgeries, simulation-based training and education, development of surgical guides and other tools, patient-specific implants, bioprinted organs or structures, and counseling of patients. It was evident that pre-procedural planning and rehearsing of unusual or difficult procedures and training of medical professionals in these procedures are extremely useful and transformative.

“…3DP can also be applied to the creation of patient-specific medical devices and customization of instruments and tools used in surgery to decrease costs and increase patient satisfaction and comfort [ 194 , 195 ]. Most medical devices are made in standardized sets of shapes and sizes and often do not provide the best fit for the patient using them.…”

Three-dimensional printing (3DP) has recently gained importance in the medical industry, especially in surgical specialties. It uses different techniques and materials based on patients’ needs, which allows bioprofessionals to design and develop unique pieces using medical imaging provided by computed tomography (CT) and magnetic resonance imaging (MRI). Therefore, the Department of Biology and Medicine and the Department of Physics and Engineering, at the Bioastronautics and Space Mechatronics Research Group, have managed and supervised an international cooperation study, in order to present a general review of the innovative surgical applications, focused on anatomical systems, such as the nervous and craniofacial system, cardiovascular system, digestive system, genitourinary system, and musculoskeletal system. Finally, the integration with augmented, mixed, virtual reality is analyzed to show the advantages of personalized treatments, taking into account the improvements for preoperative, intraoperative planning, and medical training. Also, this article explores the creation of devices and tools for space surgery to get better outcomes under changing gravity conditions.

Customized Pessary Fabrication Using Three-Dimensional Printing Technology

Abstract: We report the successful insertion of a customized three-dimensional-printed pessary in a patient with SUI. Three-dimensional-printed pessaries are feasible and their utility may extend to the patient with anatomy incompatible with commercially available pessaries.
