Hysteroscopic - Tubal Cannulation

Tubal cannulation is a technique that allows doctors to open a tubal cornua block if there are blockages in the fallopian tubes. This procedure allows gynaecologists to see inside the womb using a fine telescope called a Hysteroscope.

What is Hysteroscopic - Tubal Cannulation

Tubal cannulation is a medical procedure for women that helps them address pregnancy issues due to blockages in fallopian tubes. Women with a cornual block need to undergo this treatment after diagnosis and if their doctor recommends and allows this procedure. 

The treatment of such blockages depends on three factors. They are: 

  • Cause of the blockage
  • Location of the blockage in the tube
  • Procedure route

The hysteroscope used in the procedure is inserted into the fallopian tube from the neck of the womb. A thin wire is also passed through the hysteroscope and into the entrance of the fallopian tube. The image is visible on a monitor through which the whole process is conducted. 

The doctor diagnoses and conducts the procedure only after a proper examination of a patient’s condition. 

Hysteroscopy is done to see the distal end of the fallopian tubes and ensure their normal condition, followed by a laparoscopy. A blue-coloured dye will be injected to check whether the blockage has opened. 

When is Hysteroscopic - Tubal Cannulation done?

When a cornual block is identified in a woman’s fallopian tube during diagnostic laparoscopy, this procedure is suggested by surgeons. In cases of distal tubal disease, this operation should be avoided. Talk to your doctor to understand if you are fit to undergo hysteroscopic tubal cannulation. 

Who Should Get Hysteroscopic - Tubal Cannulation Done?

  • You can get it done if you are experiencing trouble getting pregnant due to issues in your womb.
  • If your imaging test shows a blockage in your fallopian tubes, you can get it done. 
  • If you cannot afford expensive fertility treatments, you can consider hysteroscopic tubal cannulation. 
  • You can get it done if you do not have any other reproductive system-related pathologies.

What Happens Before the Surgery?

Before the procedure, you are asked to stop eating or drinking after midnight on the day of your procedure. You should consult your doctor about the medicines you are allowed to take before the operation. Get yourself checked at the radiology department before the surgery. If the results indicate you are fit to undergo the procedure, only then can you undergo surgery.

 Your surgeon will check your medical reports, medical history, and vitals before setting up an appointment with you. Before the surgery, a nurse will inject an intravenous (IV) line containing pain medicine in your arm or hand to prevent you from feeling the pain during surgery.

What Happens During the Surgery?

The process begins similarly to the Hysterosalpingogram (HSG), a diagnostic procedure to examine your condition. You will be positioned on a flat x-ray table under a fluoroscope. The bottom portion of your body is then draped with sterile drapes. A speculum is then placed in your vagina by the radiologist or gynecologist.

A catheter is inserted into the opening of the cervix after the cervix has been cleansed. To confirm the tubal obstruction, the clinician softly fills the uterus with a liquid contrast through the catheter.

What Happens After the Surgery?

You will not be able to drive for a few hours because of the medicines you have been given. Hence, make sure you have transportation home. You will be asked to stay at the hospital for approximately 3 hours, and after that, you can go home. Abstaining from sexual intercourse for 48 hours post-surgery is recommended by doctors. After this period, you should continue your normal attempts to conceive.

Take all your medicines as directed by your doctor to avoid the possibility of infection. If you have any questions or concerns about how and when to take the medicines, contact your doctor immediately.

What are the Risk Factors of Hysteroscopic - Tubal Cannulation?

The risks include: 

  • Infection 
  • Tubal perforation
  • Ectopic pregnancy 
  • Radiation exposure 
  • Iodine allergy
  • Rash, itching, or swelling after the procedure
  • Previous fallopian tube surgery

  • Severe blockage causing problems to the catheter entering the tube 
  • Major damage to your fallopian tubes
  • Distal blockage
  • Severe tubal disease

What are the Complications of Hysteroscopic - Tubal Cannulation?

The complications include: 

  • Failure to navigate the tube and open the obstruction 
  • Failure to make sure your fallopian tube is working
  • Spotting or bleeding 
  • A tear in the fallopian tube wall
  • Pinhole tubal perforation or tubal dissection can occur in some cases. 
  • Blockages in the narrowest part of the fallopian tube 
  • Inflamed fallopian tubes
  • Severe tubal disease
  • Extensive scarring in your fallopian tubes
  • Genital tuberculosis and certain other infections


Hysteroscopic -Tubal cannulation is a medical procedure conducted on women when they experience issues with getting pregnant. The procedure is done when the fallopian tube of a woman’s reproductive system is blocked, or there are issues with the fallopian tube. A patient with a distal tube pathology cannot undergo this operation. Consultation before the procedure is key for a successful surgery. A hysteroscope is a thin instrument attached to a telescope used to conduct the procedure. It is inserted through the neck of the womb to see the condition of the blockage. A blue dye is also used to check the blockage of the tube. Common complications include the failure to navigate the tube and ensuring it works, infections, bleeding, a tear in the fallopian tube wall, pinhole tubal perforation or tubal dissection, blockages in the narrowest part of the fallopian tube, inflamed fallopian tubes, tubal diseases, scarring in your fallopian tubes, and genital tuberculosis.

This procedure is a choice for many women because it is one of the least expensive procedures and can substitute for other expensive fertility treatments. It can easily be conducted within hours after a diagnostic procedure under the guidance of skilled surgeons. You do not even need to be admitted to the hospital for a long time, and the healing is also very quick.

The insertion of the catheter during the procedure generally causes pressure and slight cramps, but the majority of women are not bothered by such pain.

IV medicine can relieve any cramping or discomfort you might experience post-surgery. Taking 600mg of ibuprofen half an hour before treatment will help prevent the pain. 

Additionally, ask your doctors if you can take pain killers for the pain after surgery.

You can bear a child if your health conditions are normal post-surgery. The success rate among women is 90%. However, it also depends on the location, severity, and procedure type in the case of obstruction in the fallopian tube.
