RESUMO
Objective:To evaluate the performance of two-dimensional fundamental sonosalpingography combined with saline infusion pelvic sonosalpingography(abbreviated as "2DFS+ SIPS" in this article) for assessing fimbrial part′s morphology and function of fallopian tubes.Methods:A total of 246 infertile women were collected from Zhejiang Provincial People′s Hospital from May 2018 to December 2019. They underwent dynamic three-dimensional harmonic sonosalpingography(abbreviated as "4DHS" in this article) first. Cases which were diagnosed as bilaterally tubal obstruction would be excluded. 2DFS+ SIPS was performed in 230 patients. Among them, 21 underwent laparoscopy and dye test(LDT) within 6 months and the results were regarded as golden standard.Results:①Tubes which were diagnosed as complete obstruction would be excluded. The total display rate of remaining fimbrial parts by using 2DFS+ SIPS and 4DHS were 77.4% and 24.0% respectively, which had statistically difference( P<0.001). ②According to 2DFS+ SIPS, fimbrial parts were classified into 3 types: normal, suspected abnormal and abnormal.Normal fimbrial parts accounted for 86.4% while suspected abnormal ones accounted for 13.6% under the condition of patency; abnormal fimbrial parts accounted for 81.2% while suspected abnormal ones accounted for 18.8% under the condition of partial obstruction. The difference in the proportion of normal and abnormal fimbrial parts according to different tubal patency was statistically significant( P<0.001). ③Fimbrial parts were classified into normal (normal fimbrial parts) and abnormal (suspected abnormal and abnormal fimbrial parts) further according to 2DFS+ SIPS, the results were compared with LDT. Accuracy, sensitivity, specificity, positive predictive value, negative predictive value and Youden′s index were 92.0%, 100%, 88.2%, 80.0%, 100%, 0.88, respectively. The consistency analysis showed the results of 2DFS+ SIPS and LDT were highly consistent (Kappa=0.828). ④All the side effects occured during the procedure or within 30 minutes after the procedure were self-limited.No serious complications were observed. Conclusions:2DFS+ SIPS is a preferred method for assessment of fimbrial part′s morphology and function, with its advantages of non-invasiveness, intuition, and accuracy. This combination could provide objective imaging basis for choosing clinical treatment strategies and predicting prognosis.
