Application Of Computer-Assisted Surgery System (Hisense CAS) In The Surgical Treatment Of Pediatric Renal Tumors

Purpose:To explore the application and clinical significance of Hisense Computer Assisted Surgery System(Hisense CAS)in the surgical treatment of pediatric renal tumors.Method:The clinical data of 23 children with renal tumors admitted to the Department of Pediatrics,Affiliated Hospital of Qingdao University School of Medicine from January 2017 to June 2022 were retrospectively analyzed.All 23 children with renal tumors underwent preoperative abdominal color Doppler ultrasound examination.Auxiliary examinations such as abdominal CT,abdominal CT and abdominal contrast-enhanced CT,and grouping the children: Among them,the computer-assisted surgery system(Hisense CAS)was used to analyze the information of the pre-operation abdominal contrast-enhanced CT,and then the tumor,kidney,kidney and ureter were analyzed.Children with 3D reconstruction of blood vessels and adjacent organs were selected as experimental group,namely reconstruction group,and children without preoperative 3D reconstruction by computer-assisted surgery system before operation were selected as control group,namely non-reconstruction group.In this experiment,all the children underwent abdominal ipsilateral ureterectomy and lymph node dissection.The clinical data of 23 children were collected,including age,gender,surgical side,clinical first symptom,maximum tumor diameter,operation time,operation blood loss,postoperative extubation time,postoperative hospital stay,recurrence and metastasis,and pathology.The clinical data of the experimental group and the control group were compared and analyzed.Results:1.The 23 sick children in this experiment all had renal tumors removed by surgical methods of abdominal ipsilateral kidney and kidney tumor,ipsilateral ureterectomy and lymph node dissection.Intraoperative exploration and postoperative pathology confirmed that the mass was Kidney tumor.2.According to whether the computer-assisted surgery system(Hisense CAS)was used to perform 3D reconstruction of tumor,kidney,kidney blood vessels,ureter and adjacent organs and blood vessels to assist preoperative evaluation and intraoperative navigation before surgery,they were divided into experimental group,reconstruction group and control group.The non-reconstruction group includes 11 children in the experimental group,the reconstruction group,12 children in the control group,the non-reconstruction group,9 female children,and 14 male children.There were no significant differences in general clinical data such as side,clinical first symptoms,maximum tumor diameter,and postoperative pathological results.3.The preoperative 3D reconstructed images of the experimental group,namely the reconstruction group,through the computer-assisted surgery system(Hisense CAS)can intuitively and clearly reflect the positional relationship and adjacent relationship between the tumor and the kidney,renal blood vessels,and ureter.In the same exploration situation,the average operation time of the experimental group,the reconstruction group and the control group without reconstruction,were 124.18 min and 168.83 min,respectively;the average surgical blood loss was 10.63 ml and90.83 ml,respectively;the difference was statistically significant.The average postoperative extubation time was 2 days and 3 days,respectively;the average postoperative hospital stay was 8 days and 10 days,respectively.The difference between the two was not statistically significant.4.All the children in this experiment were followed up regularly after operation(6 months to 36 months).Among them,2 children in the experimental group,the reconstruction group,had recurrence or metastasis after postoperative re-examination,and the control group was the non-reconstruction group.Recurrence or metastasis occurred in 4 cases,and the difference was not statistically significant.Conclusion:Use Hisense Computer Assisted Surgery System(Hisense CAS)to carry out preoperative reconstruction and improve preoperative surgical planning for children with renal tumors,guide the surgical approach and surgical plan,conduct intraoperative navigation,and complete preoperative evaluation and evaluation of children with renal tumors.Surgical treatment can improve the safety and accuracy of surgery for children with renal tumors,avoid intraoperative emergencies,reduce the probability of postoperative complications,and escort the diagnosis and treatment of children with renal tumors.
