Tubal Cannulation

Tubal Cannulation

Tubal cannulation is a minimally invasive surgery that aims to treat a blocked fallopian tube. It specifically works to restore the blockage at the proximal portion of the tube, that is, the part closest to the uterus. This blockage is called proximal tubal occlusion and is a cause of subfertility.

Unlike fallopian tube surgery, an invasive surgery requiring cuts, tubal cannulation uses a catheter inserted into the body through the vagina and the cervix, requiring no incisions or hospitalisation. 

When is a Tubal Cannulation Needed?

A normal unblocked fallopian tube lets the sperm travel up and meet the egg, allowing the fertilised egg to move down to the uterus. Tubal cannulation may be suggested by the doctor when an imaging test (hysterosalpingogram or a laparoscopy and dye test) shows complete or partial blocking of either or both fallopian tubes. This blockage obstructs the fertilisation process, leading to subfertility. 
 
The blockage can occur due to several reasons, such as scar tissue, previous infection, or endometriosis. Tubal cannulation is highly recommended and successful in cases where the blockage is at the part of the fallopian tube which is closest to the uterus, called proximal tubal obstruction. 
 

How Does a Tubal Cannulation Work?

A hysteroscopy or laparoscopy guides the catheter into the uterine cavity to find the fallopian tube opening. The doctor uses a hysterosalpingogram to flush dye through the catheter and identify the area of blockage.

Following this, tubal cannulation is conducted where an inflatable balloon is attached to the tip of the catheter, which passes the proximal portion of the Fallopian tube and is used to open the blockage. 

The patient is not under anaesthesia; instead, is given a mild sedative to relax. They can also return home after surgery on the same day. Complete recovery can take anywhere from one week to two weeks.

Tubal Cannulation is Not Suitable For?

Doctors do not recommend tubal cannulation for patients who have:

  • Extensively scarred fallopian tubes
  • Undergone previous fallopian tube surgery
  • Intense damage to fallopian tubes
  • Distal blockage – a blockage in the area of the tube farthest from the uterus.
  • Genital TB or other infection
  • Severe blockage
  • Blockage isthmus – the narrowest part of the tube
  • Inflamed fallopian tubes

 

Chances of Success in Tubal Cannulation

Tubal cannulation is highly successful for patients who have proximal tubal blockage, where the success rate is above 80%. Since tubal cannulation is a non-invasive and widely available procedure, it is often the first line of treatment suggested to patients. They can even avoid expensive treatment options like in vitro fertilisation (IVF) or embryo transfer. Patients can even avoid the risk of ovarian hyperstimulation and multiple pregnancies due to the release of multiple eggs simultaneously with tubal cannulation. 

It is also important to note that tubal cannulation may not be successful for all patients and is not recommended in case of distal tubal occlusion.

Risks Associated with Tubal Cannulation

Surgical complications can occur if a well-trained doctor does not conduct the procedure. The risks and complications associated with tubal cannulation include:

  • Perforation (tearing) of the fallopian tube wall
  • Peritonitis – a serious infection of the organ tissue leading to an inflamed abdominal cavity.
  • Abdominal haemorrhage 
  • Persisting infertility
