Asherman's syndrome; Ectropion; Prolapse Flashcards
Define Asherman’s syndrome [1]
Asherman’s syndrome is where adhesions (sometimes called synechiae) form within the uterus, following damage to the uterus.
Explain when Asherman’s syndrome occurs and the pathophysiology? [3]
After a pregnancy-related dilatation and curettage procedure, for example in the treatment of retained products of conception (removing placental tissue left behind after birth).
It can also occur after uterine surgery (e.g. myomectomy) or several pelvic infection (e.g. endometritis).
Endometrial curettage (scraping) can damage the basal layer of the endometrium. This damaged tissue may heal abnormally, creating scar tissue (adhesions) connecting areas of the uterus that are generally not connected
- There may be adhesions binding the uterine walls together, or within the endocervix, sealing it shut.
Describe the typical presentation of Asherman’s syndrome [4]
Asherman’s syndrome typically presents following recent dilatation and curettage, uterine surgery or endometritis with:
* Secondary amenorrhoea (absent periods)
* Significantly lighter periods
* Dysmenorrhoea (painful periods)
What are the options for dx Asherman’s? [4]
Which is the gold standard? [1]
- Hysteroscopy is the gold standard investigation, and can involve dissection and treatment of the adhesions
- Hysterosalpingography, where contrast is injected into the uterus and imaged with xrays
- Sonohysterography, where the uterus is filled with fluid and a pelvic ultrasound is performed
- MRI scan
Describe what is meant by a Nabathian cysts
Nabothian cysts are fluid-filled cysts often seen on the surface of the cervix.
- They are usually up to 1cm in size, but rarely can be more extensive.
- They are harmless and unrelated to cervical cancer.
NB: They are also called nabothian follicles or mucinous retention cysts.
Describe how Nabothian Cysts occur
The columnar epithelium of the endocervix (the canal) produces cervical mucus.
When the squamous epithelium of the ectocervix slightly covers the mucus-secreting columnar epithelium, the mucus becomes trapped and forms a cyst
. This can happen after childbirth, minor trauma to the cervix or cervicitis secondary to infection.
Describe the presentation of nabothian cysts [2]
Nabothian cysts appear as smooth rounded bumps on the cervix, usually near to os (opening). They can range in size from 2mm to 30mm, and have a whitish or yellow appearance.
TOM TIP: It is worth becoming familiar with photographs of nabothian cysts. They are relatively common. They can have a raised and discoloured appearance, creating concern when you first see them. With practice, you will be able to identify them correctly, and the woman can be reassured. Getting a senior opinion if there is any doubt creates a feedback loop that helps you confirm your impression and build your confidence in making the correct diagnosis.
Describe what a cervical ectropian is [2]
On the ectocervix there is a transformation zone where the stratified squamous epithelium meets the columnar epithelium of the cervical canal
- Elevated oestrogen levels (ovulatory phase, pregnancy, combined oral contraceptive pill use) result in larger area of columnar epithelium being present on the ectocervix
How might a cervical ectoprion present? [3]
This may result in the following features
* vaginal discharge
* post-coital bleeding
* spotting
Describe the link between cervical ectropian and cervical cancers [1]
Ectropion is not associated with cervical cancer in any way.
- It is worth getting familiar with distinguishing them from the appearance of cervical cancer. Always ask about smears, and if in doubt, get a senior opinion and consider referring for colposcopy.
How do you treat cervical ectropian? [1]
Treatment involves cauterisation of the ectropion using silver nitrate or cold coagulation during colposcopy.
NB: asymptomatic ectropion do not require treatment
Pelvic organ prolapse can be classified according to the affected compartments.
What are they? [3]
Anterior compartment:
- cystocele (bladder herniation) and urethrocele (urethral herniation)
Middle compartment:
- uterine prolapse (uterus descent) and vaginal vault prolapse (post-hysterectomy)
Posterior compartment:
- rectocele (rectal herniation) and enterocele (small bowel herniation)
Describe what is meant by a vault prolapse [1]
When does it occur? [1]
Vault prolapse occurs in women that have had a hysterectomy, and no longer have a uterus.
The top of the vagina (the vault) descends into the vagina.
Define rectocele [1]
Rectoceles are caused by a defect in the posterior vaginal wall, allowing the rectum to prolapse forwards into the vagina.
