How to check whether the fallopian tubes are obstructed?

The main cause of infertility is fallopian tube obstruction, which can be congenital or acquired. For example, abortion and abnormal sexual intercourse can lead to fallopian tube obstruction. When conducting an examination, it is necessary to make a diagnosis based on the patient's physical condition and personal situation. How to check for blocked fallopian tubes? The specific steps are quite complicated.

1. X-ray hysterosalpingography

Laparoscopic fallopian tube fimbrial end ostomy and fallopian tube adhesion separation can only be performed when it is determined after X-ray hysterosalpingography that the site of fallopian tube blockage is incomplete obstruction of the fallopian tube fimbria and there is suspected adhesion around the fallopian tube. Therefore, it is not recommended as a routine examination method. Usually, only when the cause of infertility in patients cannot be determined by various conventional examination methods, a routine fallopian tube perfusion examination (with methylene blue dye) is performed during endoscopic examination.

2. Hysteroscopy

It is mainly used to understand the internal situation of the uterine cavity. It can clearly understand the tiny lesions in the uterine cavity under direct vision through the combination of cold light source and endoscope. It is a microscopic examination, but it has no way of understanding the situation of the fallopian tubes outside the uterine cavity. Because the fallopian tubes are a tubular structure extending from the edge of the uterus, they are located outside the uterus. Therefore, using hysteroscopy to check whether the fallopian tubes are unobstructed is the wrong place.

3. Hysteroscopic and laparoscopic examination

There are also great limitations in checking whether the fallopian tubes are unobstructed, because hysteroscopy can only understand the situation inside the uterus, and laparoscopy can only understand the specific situation in the abdominal cavity and the tissue structure around the fallopian tubes and the presence or absence of adhesions, that is, the adhesion blockage at the fimbria of the fallopian tubes and the impact of adhesions around the fallopian tubes on the peristaltic function of the fallopian tubes. In other words, these two methods can only understand the situation at both ends and around the fallopian tubes, but there is no way to understand the specific blockage site and nature in the fallopian tube cavity. Understanding the patency of the fallopian tube cavity is the key to diagnosing and treating fallopian tube problems.

4. Check the water permeability of the fallopian tube

The correct diagnosis rate for whether the fallopian tube is patency is very poor, and the misdiagnosis rate is as high as over 50%, because this method is just a blind diagnosis.
