Tianjin Cancer Hospital completed the first 3D-printed simulated bone tumor surgery.

Recently, the bone and soft tissue oncology department of Tianjin Cancer Hospital successfully completed the removal and reconstruction surgery for a patient with a difficult pelvic bone tumor with the help of 3D printing technology, through accurate simulation rehearsal, which is also the first time that 3D printing technology has been applied to bone tumor treatment in Tianjin.
pelvic bone tumor the most ideal treatment is surgical excision plus pelvic reconstruction, but the pelvic floor structure is irregular, the surrounding important organs more, the anatomy site is complex, whether it is surgery or postoperative pelvic reconstruction, the process of trauma, bleeding, complex operation and other difficulties.
to this end, Tianjin Cancer Hospital Bone and Soft Tissue Oncology Department Director Wang Wen, according to the patient's condition, decided to use the most advanced image fusion and 3D printing rapid molding technology, the patient-related imaging data raw data input 3D editing software, according to computer data, through advanced 3D printing technology to produce a 1:1 pelvic replacement prosthesis model. Then, according to the nature of the tumor and the scope of pelvic defects, The Kingdom led the team to simulate the pelvic incision form, length, confirm the location of excision and reconstruction, and design the surgical bone-cutting guide, carry out simulation surgery, the problems that may be encountered in the operation in advance to determine the best surgical plan.
surgery, under the guidance of the bone-amputated guide, the Director of the Kingdom quickly found the location of the tumor, according to the pre-designed surgical procedure to complete the removal of the left pelvic tumor, and immediately accurate completion of the artificial pelvic reconstruction and fixation. Because of the precision of the "knife", the patient during the operation of bleeding and trauma is controlled to the lowest, the operation time is also greatly shortened, originally required more than 10 hours of major surgery, only 6 hours to successfully complete. At present, the patient's health is recovering well and he will be able to discharge himself from the hospital in recent days.
", 30 years ago, due to the lack of effective comprehensive treatment, the conventional treatment of malignant bone tumors mainly amputation, the patient's five-year survival rate of less than 20%. In particular, spinal and pelvic tumors, involving many of the surrounding blood vessels, nerves and spinal cords, require more rigour. Doctors can only discuss and anticipate multiple surgical options based on CT images, sometimes even after a knife is opened in the operating room to open the chest or abdominal cavity. Wang Wen Director introduced, 3D printing technology can help doctors more intuitive preoperative discussion, simulation of the scope of surgery, facilitate the development of surgical programs and team work, for patients to strive for maximum treatment results. This technique is particularly suitable for irregular bone tumors such as spinal tumors and pelvic bone tumors.
the advantages of 3D printing technology are not only in surgery, but also in communication. In the past, bone oncologists mostly use CT, MRI and other imaging results to introduce patients to the disease and surgical program, professional, even after repeated explanation, patients are usually still half-informed, preoperative communication is not smooth enough. The 3D-printed model is now available to patients, detailing the surgical protocol to patients and their families, and helping patients understand the treatment process. (Zhu Wei)
