Under what circumstances should the fallopian tube be removed? How to rule out whether the fallopian tube is unobstructed?

There are two fallopian tubes in the female body, which transport eggs to the uterus to achieve pregnancy. If the fallopian tubes are blocked, the uterus will not have eggs and sperm to combine, and fertilized eggs cannot be formed, and pregnancy cannot be achieved. If the fallopian tubes are severely blocked, they need to be removed. Let's learn more about it.

When should I remove the fallopian tube?

1. One side of the fallopian tube is damaged and the other side is normal

Fallopian tube torsion can cause fallopian tube necrosis, fallopian tube lesions, and tubal pregnancy rupture. Sometimes we will consider having women have their fallopian tubes removed, but the chances of women becoming pregnant will be greatly reduced.

2. Congenital malformation of fallopian tube

For this reason, we will also consider removing the fallopian tube. We have two fallopian tubes in total. If one is removed, women still have a 50% chance of pregnancy, and the other fallopian tube can also be used to pick up eggs.

3. Abnormal fallopian tube

The fallopian tube is one of the appendages of the uterus. If there is a large mass, tumor, tuberculosis infection, or severe hydrops in the appendage, it is necessary to consider resection. Among them, the well-known "ectopic pregnancy" is one.

How to rule out blockage of fallopian tubes

To determine whether the fallopian tube is unobstructed, these tests are usually performed:

Hysterosalpingography

It is usually done 2-7 days after the menstrual period. Try not to have sex before and two weeks after the fallopian tube examination. Our fertility doctors can clearly see the shape of the fallopian tubes and the size, shape and position of the uterus from the fluorescent screen and X-ray photos through hysterosalpingography via X-ray.

Hysteroscopy and laparoscopy

By using endoscopy to directly enter the patient's abdominal cavity, the condition of the fallopian tubes can be observed in the most intuitive way, and it has a therapeutic effect on fallopian tube obstruction, fallopian tube adhesions, and hydrosalpinx.

Ultrasonography

It is divided into general ultrasound and ultrasound-assisted fluid flow.

Conventional ultrasound can detect hydrosalpinx, which is manifested by thickened liquid dark areas on both sides of the uterus; fluid flow cannot confirm whether it is hydrosalpinx or ovarian cyst, we can only say "it indicates the possibility of hydrosalpinx".

Common causes of blocked fallopian tubes

Chronic pelvic inflammatory disease Pelvic adhesions

It causes adhesions in the inner mucosa of the fallopian tube, narrowing or blocking the lumen. In severe cases, the fallopian tube may become stiff and twisted, and women may completely lose their fertility.

Perforated appendix

The appendix and fallopian tube are neighbors, so it is easy for them to adhere to each other.

abortion

Women with a history of miscarriage are prone to infection, and inflammation can leave scar tissue in the fallopian tubes and damage them.
