Bartholin's Cyst and Abscess

What are Bartholin's glands and what do they do?


Bartholin's glands are a pair of small glands that are just next to the lower part of the entrance to the vagina. Each gland is about the size of a pea. Unless diseased or infected, you cannot normally see or feel these glands, as they are within the soft tissues (labia) next to the entrance to the vagina.

Female genitals


Each gland makes a small amount of mucus-like fluid. The fluid from each gland drains down a short tube (duct) called the Bartholin's gland duct. Each duct is about 2 cm long and comes out towards the lower part of the entrance to the vagina. The fluid helps to keep the entrance to the vagina moist.

Bartholin's glands are named after Thomas Bartholin, the doctor who first described them in the 18th century. Bartholin's glands are sometimes called vestibular glands.

What problems can arise from Bartholin's glands?


Bartholin's cyst


If the tube (duct) that drains the fluid becomes blocked then a fluid-filled swelling (cyst) develops. The size of a cyst can vary from small and pea-like to the size of a golf ball, or even bigger in some cases. The cyst may remain the same size or may slowly become bigger. The reason why a Bartholin's duct may become blocked and lead to a cyst is not clear.

Bartholin's abscess


An abscess is a collection of pus that can occur with an infection.  An abscess can occur in any part of the body, and sometimes occurs in a Bartholin's gland. Sometimes an abscess develops from a Bartholin's cyst that becomes infected. Sometimes the gland itself becomes infected which gets worse and forms into an abscess. Within a few days, the abscess can become the size of a hen's egg, sometimes larger, and is usually very painful.

Many types of germs (bacteria) can infect a Bartholin's cyst or gland to cause an abscess. Most are the common germs that cause skin or urine infections, such as Staphylococcus spp. and Escherichia coli. So, any woman can develop a Bartholin's abscess. Some cases are due to sexually transmitted germs such as gonorrhoea or chlamydia.

Bartholin's gland cancer


This is a very rare cancer (about 1 in a million chance of a woman having it) and is very unlikely in women aged under 40. However, if there is any doubt about the cause of the swelling, a small sample of tissue (biopsy) can be checked.

Who gets Bartholin's cysts and abscesses?


About 3 in 100 women will develop a fluid-filled swelling (Bartholin's cyst) or a collection of pus (Bartholin's abscess) at some point in their life. So, they are a common problem. Most cases occur 'out of the blue' in women aged between 20 and 30. However, they can also occur in older or younger women.

What are the symptoms of Bartholin's cysts and abscesses?


As mentioned earlier, a fluid-filled swelling is a cyst. A collection of pus is an abscess. A Bartholin's cyst or abscess typically only develops on one of the two glands. If a cyst remains small and does not become infected then you may have no symptoms. You may just feel a small lump to one side at the lower end of the entrance to the vagina, which may cause no problems. However, a larger cyst may cause some discomfort - in particular, when walking, sitting, or having sex. Very large cysts can become quite painful.

With an abscess, a lump develops and quickly gets bigger, typically over a few hours or days. It is likely to become very painful. You may feel unwell and have a high temperature, and the skin over the abscess tends to become red, hot and very tender.

Some women may also have some vaginal discharge also.

How is it diagnosed?


An examination by a doctor can usually diagnose the problem. A Bartholin's fluid-filled swelling (cyst) and collection of pus (abscess) have a typical appearance. No test is usually needed to make the diagnosis.

What is the treatment for Bartholin's cysts and abscesses?

 

Treatment is not always neededIf you have a small fluid-filled swelling (cyst) that causes no symptoms, and does not become infected, then it may be best simply to leave it alone. However, you should always report a 'lump' in the area around your vagina (your vulva) to your doctor. Do not just assume a small lump is a Bartholin's cyst. It is best for a doctor to examine you to confirm the diagnosis and to rule out other causes of lumps in the vulva. If a cyst causes symptoms, then it can be treated.

A collection of pus, confirmed as a Bartholin's abscess, will almost always need treatment, as it can be very painful. However, if an abscess is left long enough it is likely to burst and then may resolve without treatment. This is not recommended though, as it will be very painful and you could become quite ill.

Antibiotic medicines for an infection or abscess


A course of antibiotics may cure an infected gland or abscess. However, as a rule, the more pus that forms, the larger the abscess, and the less chance that antibiotics alone will be sufficient to clear the abscess without also needing to drain the pus.

A small operation is needed in many cases
The main aim of the operation is to drain any fluid or pus. This relieves symptoms. In addition, another aim is to minimise the chance of the problem happening again (recurring).

Marsupialisation


A small operation called marsupialisation is the traditional treatment used to treat a Bartholin's cyst or abscess. It may be done under general anaesthetic. However, it can also be done under local anaesthetic when the overlying skin is numbed with an injection of local anaesthetic. A small cut (incision) is made into the cyst or abscess just inside the entrance to the vagina. Any fluid or pus drains out. The cut is widened to about 1 cm. A few stitches are then used to stitch the inside lining of the cyst to the overlying skin. This then creates a small new permanent opening for fluid to drain out of the gland.

Initially, the opening that is left is like a pouch - hence the name of the operation. However, the opening gradually becomes smaller and soon the opening becomes tiny and not noticeable. But this new opening is, in effect, like a new tube (duct) which allows any fluid that is made by the gland to drain.

A course of antibiotics may be prescribed if pus is drained from an abscess. However, antibiotics are not always needed once the pus has been drained.

Marsupialisation is usually successful. In only a few cases does the problem recur if this procedure is done. If a simple cut is made to drain the fluid or pus without then doing a marsupialisation, there is a higher chance that the problem will recur at some point.

As with all operations there is a small chance of problems. For example, infection of the wound occurs in a small number of cases following marsupialisation.

Other techniques


Some people recommend that sitting in a warm bath for 10-20 minutes, three or four times a day, may encourage a Bartholin's cyst to burst naturally. It is not clear how well this may work. However, it is always best to see a doctor if you think an abscess is developing.

Other less commonly used procedures include application of silver nitrate to an abscess cavity, and use of a carbon dioxide laser.

Sometimes the entire gland is removed by a surgical operation. This is considered a 'last resort' but may be advised if you have several recurrences of a Bartholin's cyst or abscess.

Will it happen again?


In most cases, a Bartholin's fluid-filled swelling (cyst) or collection of pus (abscess) does not happen again (recur) after treatment with one of the operations described above, or if antibiotics alone cured the problem. However, they do recur in some cases when treatment needs to be repeated.

Cases due to sexually transmitted infections


If you have a Bartholin's gland infection or abscess, a swab - a small ball of cotton wool on the end of a thin stick, used to take a sample - of the area or a sample of pus is usually sent to the laboratory to identify which germ (bacterium) caused the infection. If a sexually transmitted germ is the cause of the infection then further screening for other sexually transmitted infections for yourself and your partner will usually be advised.

Can Bartholin's cysts or abscesses be prevented?
Not usually.  Most occur 'out of the blue' for no apparent reason. Some Bartholin's abscesses are due to sexually transmitted infections, and so using a condom when having sex may prevent some cases.

I had the pleasure of attending this practice on both my pregnancies an the level of service was outstanding, from the warm welcome we received when we arrived an the level of care provided to us on all visits. Nicola W (via facebook)
