Abstract：Objective To investigate the safety and efficacy of wireless biliary contrast agent injection systems in clinical applications.Methods A prospective,randomized,controlled clinical trial was designed in the First Affiliated Hospital of Xi'an Jiaotong University(June to October 2022).A total of 200 patients requiring cholangiography were randomly divided into an equipment group and a manual group.Cholangiography was performed using a wireless biliary contrast agent injection system and a traditional manual injection method,respectively.The angiographic effect,incidence of post-angiographic complications,and the amount of ionizing radiation suffered by the operator were compared between the two groups.Results A total of 95 patients in the equipment group and 98 patients in the manual group were included in this study.There was no significant difference in the angiographic effect between the two groups,and the structure of the biliary system and the location of the lesion could be displayed.The incidence of post-contrast complications in the equipment group was 5.3％,which was significantly lower than 14.3％in the manual group(P＜0.05).The operator in the equipment group had a radiation dose of 0.01(0.01,0.01)μSv during angiography,which was much lower than 3.72(5.15,1.71)μSv in the manual group(P＜0.001).Conclusion A Wireless biliary contrast agent injection system is a safe and effective new cholangiography program,that can eliminate the occupational exposure of operators and reduce the adverse reactions of patients while ensuring the contrast effect.It is worthy of being widely popularized in clinical applications.Future studies should further investigate the applicability and advantages of this system in different types of biliary tract diseases and different routes of cholangiography.
