高压注射器法与手工推注法在输卵管造影及再通术中的应用比较

Application of High-Pressure Syringe and Manual Injection in Salpingography and Fallopian Tube Recanalization: A Comparison Study

目的探讨高压注射器法与手工推注法在输卵管造影(HSG)及输卵管再通术中的优劣,比较其临床价值。方法搜集门诊准备进行HSG的不孕症患者共计240例,随机分为高压注射器组和手工推注组,每组各120例,对两组患者的造影检查结果和并发症情况进行列表统计。用SPSS 17.0软件进行统计学分析,采用χ2检验,检验水准α=0.05。结果两组患者的阳性率有统计学差异(χ2=30.42,P<0.01)。再通成功率和怀孕率没有明显的统计学差异(χ2=0.21,P>0.05,χ2=0.09,P>0.05)。并发症中两组患者的逆流率和出血率均有统计学差异(χ2=8.47,P<0.01;χ2=4.99,P<0.05),其余并发症无明显差异。结论高压注射器造影法能够将HSG技术规范化,减少工作人员X线辐射,有利于该技术的发展和推广,同时能够在一定程度上降低HSG的假阳性率。但是其逆流和出血等并发症发生率较手工推注组要高,尚有许多有待改进之处。

Objective To discuss the pros and cons of high-pressure syringe and manual injection in salpingography and fallopian tube recanalization,and to compare the clinical values of the two methods.Methods A total of 240 infertility patients who was ready to receive salpingography in outpatient clinic were collected.The patients were randomly and equally divided into high-pressure syringe group（ n = 120） and manual injection group（ n = 120）.The list of statistics of the salpingographic results and the occurrence of complications of the two groups were conducted.Statistic analysis was made by SPSS 17.0 software,using χ2test,inspection level α = 0.05.Results Statistically significant difference in the positive rate existed between the two groups（ χ2= 30.42,P〉0.01）,although no significant differences in the success rate of recanalization and pregnancy rate were found between the two groups（ χ2= 0.21,P〉0.05; χ2= 0.09,P〉0.05）.The differences in the complication occurrence of counter-flow of contrast agent and bleeding were statistically significant between the two groups（ χ2= 8.47,P〉0.01; χ2= 4.99,P〈0.05）,although the differences in the occurrence of other complications were not significant.Conclusion In performing salpingography the use of high-pressure syringe is superior to manual injection as it can make the salpingography technology standardization and reduce the radiation dose to medical workers,which are very helpful in promoting and popularizing this technique in clinical practice.Meanwhile,the use of high-pressure syringe can reduce the false positive rate of salpingography.Nevertheless,the complication occurrence such as counter-flow of contrast agent,bleeding,etc.in high-pressure syringe group is higher than that in manual injection group,and still there is much to be improved.
