HYSTEROSCOPIC TUBAL CANNULATION
What is Hysteroscopic Tubal Cannulation ?
Hysteroscopic Tubal Cannulation is a medical procedure that allows for the viewing of the entire uterine cavity. This will be useful for diagnosing and treating other medical issues that occur while performing cannulation.
Tubal cannulation is the procedure that involves opening up the tubal corneal blocks at the origin of the fallopian tubes near the uterus. This is normally performed under hysteroscopic guidance. This procedure also helps restore fertility in some women.
In this procedure, a fine wire is passed through the hysteroscope into the opening of the fallopian tubes. The portion of the fallopian tubes at the junction of the uterus and tubes as thin as hair. This procedure will remove the Fallopian Tube Blockage caused by mucous plugs or debris, restoring the tubal patency.
The surgeon might opt for a Laparoscopy for visualizing the distal end of the fallopian tubes and to confirm their normal status. Laparoscopy is used to pass the guide wire through the tube and a blue dye is pushed to check whether the tube has opened.
The doctor inserts a tube guided over a wire to the affected area under hysteroscopy guidance. After that, the blocked area in the fallopian tube is opened using a balloon on the catheter. Tubal cannulation is performed. During this procedure, the dye is flushed through the catheter to confirm patency of tubes. A sedative may or may not be used during this procedure.
The patient is recommended to follow the doctor’s instructions after the procedure to maintain the best results. In some selected cases, tubal cannulation has found to have good success rates similar to IVF. However, it also avoids the risk of ovarian hyperstimulation and multiple pregnancies. It is also possible that the woman will have subsequent spontaneous pregnancies following the procedure. Pregnancy rates depend on the:
- Location of the blockage.
- Specific procedure performed.
- Cause of the blockage.
- Persisting infertility
- Perforation in the wall of the Fallopian tube
- Inflammation of the abdominal cavity called peritonitis
- Haemorrhage (bleeding into the abdominal cavity)
In rare cases, some patients have faced the following:
- Blockage in the Fallopian tube is normally found in the distal part (closest to the ovary) or in the isthmus (the narrowest part)
- Heavy scarring of the fallopian tubes
- Fallopian tubes active inflammation
- Tubal tuberculosis
