Abstract

OBJECTIVES: The purpose of this study was to evaluate the diagnostic efficacy of transvaginal two-dimensional fundamental sonosalpingography (2D-FS) combined with saline infusion pelvic sonosalpingography (SIPS) for assessing fimbrial part's morphology and function of the fallopian tubes. METHODS: One hundred and sixty-nine cases underwent 2D-FS combined with SIPS. Among them, 18 cases received laparoscopy and dye test (LDT) within 3 months after the examination and the results were regarded as reference standard. RESULTS: Excluding proximal or middle segment obstructed tubes, the remaining fimbrial parts' display rate by using 2D-FS combined with SIPS was 75.1%. According to the ultrasonic appearance, the fimbrial parts were classified into 4 types: normal, abnormal, suspected abnormal, and unclassifiable. Normal fimbrial parts accounted for 73.8% when the tubes were patent; abnormal fimbrial parts accounted for 74.1% when the tubes were partial obstructed; all became abnormal when the tubes were distal complete obstructed. The fimbrial parts which had been classified by 2D-FS combined with SIPS were compared with LDT further. This combination's accuracy (ACC), sensitivity (SEN), specificity (SPE), positive predictive value (PPV), negative predictive value (NPV), and Youden's index (YI) were 86.4, 87.5, 85.7, 77.8, 92.3, and 0.73%, respectively. The result of consistency analysis showed the combination was essentially consistent with LDT result (Kappa = 0.713). CONCLUSION: 2D-FS combined with SIPS can be a preferred method for assessment of the fimbrial part's morphology and function, with its advantages of non-invasive, intuition, and accuracy. This combination could provide an objective imaging basis for choosing clinical treatment strategies and predicting prognosis.
