目的探讨子宫输卵管造影(HSG)中,双腔球囊导管顶端位置的不同对该侧输卵管显示率的影响。方法选择HSG检查中导管顶端紧邻子宫角部且无明显间隙,当对比剂注入4~5 ml或对侧输卵管全程对比剂显影而该侧输卵管仍未见对比剂显示的受检者72例,按不同操作方法随机分为A、B、C三组进行对比研究。A组(23例):保持原状态,即不调整双腔球囊管的位置及球囊大小继续注药;B组(30例):放出球囊气体约0.5~1 ml后继续注药,以导管顶端周缘出现对比剂为度;C组(19例):在继续注药的同时轻拉导管,以导管不脱出为度。每次拉动持续时间不少于1 s,每拉动3次为1个观察周期。摄片观察、记录双侧输卵管的显示情况并作组间对照。数据分析采用SPSS 12.0进行卡方检验。结果 A组显示通畅率为30.43%(7/23),B组为76.67%(23/30);C组为63.16%(12/19)。A、B两组间对照,差异均有显著统计学意义(χ2=11.328,P=0.001);A、C两组间对照,差异均有统计学意义(χ2=4.497,P=0.034);B、C两组间对照,差异无统计学意义(χ2=1.040,P=0.308)。结论当导管顶端紧邻子宫角部时,适当减小球囊体积或向外轻拉导管是提高输卵管显示率的有效方法。
Objective To investigate the effect of different positions of dual-balloon catheter on the display of the fallopian tube in hysterosalpingography (HSG). Methods HSG examination in the top of the catheter close to the corner of the uterus and no significant gap when the contrast agent injection 4 ~ 5 ml or contralateral fallopian tube contrast agent development and the side of the fallopian tube still showed no contrast agent 72 subjects, press Different methods of operation were randomly divided into A, B, C three groups for comparative study. In group A (n = 23), B group (n = 30): keeping the original state, that is, not adjusting the position of double-lumen balloon tube and the size of balloon; group B Contrast agent was taken at the periphery of the catheter tip. Group C (n = 19): the catheter was gently pulled while continuing to inject the drug, and the catheter was not prolapsed. Each pull duration of not less than 1 s, 3 times for each pull for a observation period. Radiographic observation, recording both sides of the fallopian tubes showed the situation and as a control group. Data analysis using SPSS 12.0 for chi-square test. Results Group A showed patency rate of 30.43% (7/23), group B 76.67% (23/30) and group C 63.16% (12/19). There was significant difference between A and B groups (χ2 = 4.497, P = 0.034); B , C between the two groups, the difference was not statistically significant (χ2 = 1.040, P = 0.308). Conclusion When the catheter tip is close to the corner of the uterus, appropriately reducing the volume of the balloon or pulling the catheter lightly is an effective method to improve the display rate of the fallopian tube.
