The Use of a New Gel Foam for the Evaluation of Tubal Patency

Abstract

Aims: To evaluate the feasibility and the reliability of hysterosalpingo-foam sonography (HyFoSy) using gel foam in the assessment of tubal patency. Methods: Nonrandomized, observational, academic and single-center study of 20 women being investigated because of subfertility and scheduled for a laparoscopy with chromopertubation. A detailed description of HyFoSy with a newly developed gel foam is given in the way it proved to be most efficient in our hands. The results of HyFoSy are compared to the data regarding tubal patency testing during laparoscopy by chromopertubation. Results: All 20 HyFoSy were technically successful. Four of the 40 tubes, 1 right tube and 3 left tubes, were not patent at HyFoSy (3 tubes with proximal block and 1 tube with distal block). There was a 100% agreement between tubal patency data according to HyFoSy testing and laparoscopic chromopertubation testing. Conclusion: HyFoSy is both feasible and accurate in the diagnosis of tubal patency.

Pelvic Inflammatory Disease: A Retrospective Clinical Analysis of 1,922 Cases in North China

“…If a little fluid spills out of the ends with some resistance when 15-20 ml fluid is injected, they are incompletely occluded. If the fluid does not spill out of the ends with greater pressure, the tubes are occluded [5]. Significance was assessed using the χ 2 test, and p < 0.05 was considered statistically significant.…”

Effectiveness and feasibility of hysteroscopic sterilization techniques: a systematic review and meta-analysis

“…Other new nonradiation techniques such as contrast infusion sonography, hysterosalpingocontrast sonography (43), or hysterosalpingofoaminfusion sonography also have potential as confirmation tests for tubal occlusion (44,45). Above all, appropriate RCTs and observational studies with sufficient power and followup are needed for relevant and complementary information in addition to the body of evidence on the effectiveness of hysteroscopic sterilization techniques.…”

Endoscopic Explanation of Unexplained Infertility

“…Despite its wide spread usage in many clinics, the main drawbacks of SIS are failure to localize the side of tubal patency and failure to properly visualize the tubes. Trials to improve results of SIS included the use of gel foam instead of saline [33], use of B-flow ultraspnography [34], 3D ultrasonography [35] or even sophisticated automated ultrasonography [36]. In the era of evidence-based medicine, Rubin pertubation tubal patency test is no longer implemented in modern practice [37] because it is very subjective and non-specific.…”
