- Abstract:
- ObjectiveTo explore the value of computer assisted surgical system (CAS) in precision surgery of retroperitoneal teratoma.MethodsThe clinical data of 16 hospitalized children with retroperitoneal teratoma from August 2013 to August 2017 were analyzed retrospectively.Abdominal dynamic enhanced computed tomography (CT) scan was performed preoperatively (n=16).Hisense CAS system was used for threedimensional (3D) reconstruction as reconstruction group (n=9).Based on the CAS reconstruction results，accurate preoperative diagnosis and adjuvant surgical planning were performed for determining optimal surgical protocols.The remaining 7 patients of control group underwent 3D CT reconstruction by CT Workstation.The clinical outcomes were analyzed and compared between two groups.3D reconstruction of abdominal organs and blood vessels was generated using Hisense CAS system.Diagnosis and preoperative planning assisted by the system were used for preoperative and intraoperative decisionmaking for precise surgery.ResultsThe results of threedimensional reconstruction could distinctly depict abdominal blood vessels，parenchymal organs and tumor tissue.Tumor tissues structure might be observed stereoscopically from any angle and a separate display of organs around tumor was visible for operators to understand the spatial relationship between tumor and surrounding tissue.Based upon the results of 3D reconstruction，preoperative evaluation and surgical planning were performed to reduce operative duration，blood loss and blood transfusion rate.The mean operative duration was shorter in reconstruction group than that in control group ［(111±34.41) vs (145±29.92) min，P<0.05］.The mean intraoperative blood loss was lesser in reconstruction group than that in control group ［(7±6.96) vs (30±34.48) ml，P<0.05］.The rate of blood transfusion was lower in reconstruction group than that in control group (22.22% vs 42.9%).The average hospitalization stay was shorter in reconstruction group than that in control group ［(7±1.27) vs (8±2.1) days，P<0.05)］.The difference was statistically significant.ConclusionThreedimensional visualization technology can transform 2D into 3D images and enable fulldimension rotation and zooming.Also it can depict tumor type and size，blood vessel distribution and anatomical correlation with other vessel and invasiveness in organs.It improves the safety and precision in young children undergoing retroperitoneal teratoma surgery.
