Abstract
With the development of computer medical imaging technology, three-dimensional technology has been gradually applied in medicine. We try to investigate the application value of 3D technology in the preoperative evaluation of retroperitoneal tumors. The clinical data of 70 retroperitoneal tumor cases admitted to the clinical center were retrospectively analyzed. The preoperative abdominal CT images were converted to 3D images using XMQB liver 2.0 software. These 3D images were imported into XMQB-I human organ model 3D printing equipment, and physical models facilitate preoperative evaluation and surgical strategy. The reestablished models were compared with the actual conditions during the operation. 3D imaging was completed in all the 70 cases, containing 24 cases in the left abdominal cavity, 26 cases in the right abdominal cavity, 5 cases in the pelvic cavity, and 15 cases in the multi-sites. Also, 3D printing was successfully carried out in 20 cases. The 3D imaging and 3D printing models could stereoscopically, clearly and objectively display the spatial relationships of the tumor with surrounding organs and vessels. The operation was successfully performed on all the 70 cases without death during the preoperative period. 3D technology could accurately evaluate the retroperitoneal tumors at different positions before the operation, showing a certain value in making the preoperative strategy.
Highlights
Three-dimensional (3D) technology mainly consists of 3D imaging and 3D printing. 3D imaging technology refers to 3D visualization models reconstructed by software using twodimensional (2D) CT images
We explored the application value of 3D technology in the preoperative evaluation of retroperitoneal tumors by using it to make preoperative strategy for 70 cases with retroperitoneal tumor
Pyelography showed that the long axis of right renal shadow which located in middle abdomen and overlapped with the vertebral bodies of the third and forth lumbar vertebra, was at transverse position, and midupper right ureter moved to the left side, which suggested retroperitoneal space-occupying lesion-caused right kidney displacement
Summary
Three-dimensional (3D) technology mainly consists of 3D imaging and 3D printing. 3D imaging technology refers to 3D visualization models reconstructed by software using twodimensional (2D) CT images. Three-dimensional (3D) technology mainly consists of 3D imaging and 3D printing. 3D imaging technology refers to 3D visualization models reconstructed by software using twodimensional (2D) CT images. The IQQA system developed by EDDA Company is currently the most popular software for 3-D visualization, and XMQB software for 3G imaging has been developed by Xiamen Qiangben Technology Company Ltd in China. 3D imaging technology has been widely applied in hepatic surgery, plastic surgery and orthopedics, but it is rarely applied in the preoperative evaluation of retroperitoneal tumors. Based on 3D imaging, 3D printing technology emerged in the 1980s. Different from traditional material processing methods, 3D printing is. [1] The technology is mainly applied in space industry, architecture, car industry and heritage conservation. We explored the application value of 3D technology in the preoperative evaluation of retroperitoneal tumors by using it to make preoperative strategy for 70 cases with retroperitoneal tumor
