What should I pay attention to after the fluid is passed?

After the fallopian tube cannulation, you must emphasize care and keep your private parts clean. Sexual intercourse is strictly prohibited within two weeks after the operation. In addition, you cannot take a sitz bath within two weeks after the operation. Pay attention to the cleanliness of your private parts. This is the only way to ensure the success of the operation. Fallopian tube insufflation is a common method for treating fallopian tube obstruction. When women suffer from infertility, this method can be considered for treatment.

What should I pay attention to after the fluid is passed?

If acute abdominal pain occurs during the operation, attention should be paid to whether the fallopian tube is ruptured. Generally, if the fallopian tube is blocked, there will be a feeling of distension and pain in the lower abdomen when more than 10 ml of liquid is injected. However, when the pressure is relaxed and the liquid flows back into the syringe, the pain disappears, which is different from a fallopian tube rupture. If the operation is performed close to the menstrual period, the endometrium is easily exfoliated and injected into the abdominal cavity. Long-term follow-up is required after the operation to check whether endometriosis is present. No sexual intercourse or bathing for 2 weeks after surgery.

The surgical steps of fallopian tube insufflation

Time selection for fallopian tube insufflation: Generally it is performed within one week after the menstruation ends. If it is too early, the endometrium has not been completely repaired or there is residual menstrual blood, which can easily be injected into the abdominal cavity. If it is done too late, such as during the luteal phase, the endometrium will be thicker. If a metal head is used, it will easily damage the endometrium and bring the endometrium into the abdominal cavity.

Perform routine disinfection, wear sterile gloves, spread a drape, place the speculum, insert the liquid-clearing tip into the cervical tube, connect the tail with a syringe, and slowly inject the liquid. Pay attention to the resistance, whether there is backflow, and whether there is leakage. If all the liquid can be injected without resistance or reflux, it means the fallopian tube is unobstructed; if the resistance is large, the needle pressure is relaxed and 10ml flows back into the syringe, then the fallopian tube is blocked; if the resistance to liquid injection is large and there is a small amount of reflux, it means the fallopian tube is unobstructed. Do not force injection if you encounter resistance.

Disadvantages of surgery

Although hysterosalpingography has been widely used in clinic for a long time due to its advantages such as simple equipment, convenient operation and low price, it has also exposed the following disadvantages in long-term use:

1. Hysterosalpingography is a procedure that uses a catheter to inject liquid into the uterine cavity. The volume and surface area of ​​the uterine cavity are much larger than the cross-sectional area of ​​the catheter and fallopian tube. According to the principles of fluid dynamics, the pressure is equal to the pressure divided by the force-bearing area, so the pressure of the liquid injected into the fallopian tube is very limited.

2. In actual clinical work, we have also found that the misdiagnosis rate of hysterosalpingography is as high as over 50%. It is impossible to determine the site of tubal obstruction, nor the severity and nature of tubal obstruction, and there is a risk of causing heavy bleeding like ectopic pregnancy.

3. Because the basic principle of hysterosalpingography is basically the same as that of hysterosalpingography, if the adhesion of the fallopian tube is mild, it will be restored to patency during hysterosalpingography. If hysterosalpingography cannot restore the patency of the fallopian tube, then hysterosalpingography will not have any effect.

4. Hysterosalpingography is a blind procedure. During the procedure, the specific progress of the injected fluid in the patient's body cannot be seen, so the location and nature of the fallopian tube obstruction cannot be determined. This is of no help in determining the treatment method and efficacy of fallopian tube obstruction.
