Generally, a laparoscopy is carried out under general anaesthetic and carbon dioxide is introduced into the lesser pelvis to create space. The method we use, however, is much gentler: we have easy access to the abdominal cavity at its lowest point using a needle puncture technique behind the uterus, known as the pouch of Douglas.
In addition, we do not fill the lesser pelvis with carbon dioxide, but with approx. 200 ml of sterile saline. This means that we can precisely evaluate both tubal patency (whether the fallopian tubes are clear) and the whole lesser pelvis without the need for additional incisions.
In previous years, this means of access has become more widely used, particularly thanks to the development of smaller cameras and a special spring mechanism for the puncture. In combination with uterine endoscopy, which is logically carried out beforehand, this procedure is called transvaginal endoscopy (TVE).
In addition, tubal patency can also be investigated with Hystero Contrast Sonography (HyCoSy). For this, a small, flexible catheter is inserted into the uterus before ovulation, and up to 10 ml of contract medium is carefully injected. This method can also be carried out as an out-patient procedure.
Of course, at the Frankfurt Fertility Centre, we carry out examinations with the most modern ultrasound machines, which guarantee the highest levels of precision. Get in touch with us to arrange an appointment - we would be happy to explain everything to you in detail.
