Retained products of conception: management

A
  • Remove them surgically
  • ERCP: the cervix is gradually widened using dilators and the products are manually removed using vacuum aspiration and curettage (scraping).
  • The two complications are Endometritis and Asherman’s syndrome

Q

When to start investigations for infertility

A

Investigations and referral for infertility should be started when the couple has been trying to conceive for 12 months. This can be reduced to 6 months if the women is older than 35 as her ovarian stores are likely to be already reduced

Q

Female hormone testing involves

A
  • Serum LH and FSH on day 2 to 5 of the cycle
  • Serum progesterone on day 21 of the cycle (or 7 days before the end of the cycle if not a 28-day cycle).
  • Anti-Mullerian hormone
  • Thyroid function tests when symptoms are suggestive

Q

Female hormone testing results

A
  • High FSH suggests poor ovarian reserve
  • High LH suggests PCOS
  • A rise in progesterone on day 21 indicates that ovulation has occurred
  • Anti-Mullerian hormone, high levels suggest good ovarian reserve. Can be measured any time in the cycle

Q

Types of prolapse

A
  • Uterine: when the uterus descends into the vagina
  • Vault: in women that have a hysterectomy and no longer have a uterus, the top of the vagina (the vault) descends into the vagina
  • Rectocele: defects in the posterior vaginal wall which cause the rectum to prolapse forwards into the vagina, associated with constipation
  • Cystocele: defects in the anterior vaginal wall, causing the bladder to prolapse backwards into the vagina. Prolapse of the urethra is also possible (urethrocele). Prolapse of both bladder and urethra I called cystourethrocele

Grading using the pelvic organ prolapse quantification

A

Q

Surgery for uterine prolapse

A
  • Vaginal hysterectomy: traditional treatment, not often effective
  • Hysteropexy, open or laproscopic: the uterus and cervix are attached to the sacrum using a bifurcated non-absorbable mesh

Q

Vaginal vault prolapse treatment

A

1) Sacrocolpexy, which can be laproscopic or open, fixes the vault to the sacrum using a mesh. Complications include mesh erosion and haemorrhage.
2) Sacrospinous fixation is performed vaginally and suspends the vault to the sacrospinous ligament. Complications include nerve or vessel injury, infection and buttock pain. It is less effective but recovery is faster.

Q

Vaginal wall prolapse

A

Anterior and posterior ‘repairs’ are used for the relevant prolapse but, as several prolapses may occur in one patient, these operations are often combined.

Q

Surgery for urodynamic stress incontinence

A

If this is present, the tension-free vaginal tape (TVT), transobturator tape (TOT) procedures, or Burch colposuspension may be performed at the same time as prolapse repair.

22
Q

Prolapse investigation

A

Speculum

23
Q

What does cervical cancer screening involve

A
  • HPV primary screening and if this is positive then LBC is analysed
  • Liquid based cytology (LBC) to detect early abnormalities of the cervix which if untreated can lead to cancer of the cervix
  • Cervical screening is not a test for cancer
  • Colposcopy to diagnose cervical intraepithelial neoplasia (CIN) and to differentiate high grade lesions from low grade abnormalities in women with abnormal cytology
24
Q

Management of results: negative hrHPV

A

Return to normal recall unless:
* the test of cure (TOC) pathway: individuals who have been treated for CIN1, CIN2, or CIN3 should be invited 6 months after treatment for a test of cure repeat cervical sample in the community
* the untreated CIN1 pathway
* follow-up for incompletely excised cervical glandular intraepithelial neoplasia (CGIN) / stratified mucin producing intraepithelial lesion (SMILE) or cervical cancer
* follow-up for borderline changes in endocervical cells

25
Q

Management of results: positive hrHPV

A
  • Samples are examined cytologically
  • If the cytology is abnormal -> colposcopy
26
Q

Abnormal cytology results

A
  • borderline changes in squamous or endocervical cells.
  • low-grade dyskaryosis.
  • high-grade dyskaryosis (moderate).
  • high-grade dyskaryosis (severe).
  • invasive squamous cell carcinoma.
  • glandular neoplasia
27
Q

If the cytology is normal (i.e. hrHPV +ve but cytologically normal) the test is repeated at 12 months

A
  • if the repeat test is now hrHPV -ve → return to normal recall
  • if the repeat test is still hrHPV +ve and cytology still normal → further repeat test 12 months later:
  • If hrHPV -ve at 24 months → return to normal recall
  • if hrHPV +ve at 24 months → colposcopy
28
Q

Smear test: If the sample is inadequate

A
  • repeat the sample within 3 months
  • if two consecutive inadequate samples then → colposcopy

Individuals who’ve been treated for CIN1, CIN2 or CIN3 should be invited 6 months after treatment for a test of cure. Repeat cervical sample in the community.

29
Q

Treatment of CIN

A
  • Large loop excision of transformation zone (LLETZ) is the most common treatment for cervical intraepithelial neoplasia. LLETZ may sometimes be done during the initial colposcopy visit or at a later date depending on the individual clinic.
  • Cryotherapy- in low grade CIN
  • Hysterectomy- persistent disease in women nearing/after menopause or after LETZ
30
Q

Colposcopy

A

Done if cervical screening finds HPV. A speculum is inserted into the vagina to open it. A microscope is used to look at the cervix in greater detail, the microscope stays outside the body. An endocervical brush is used to take a sample of further testing. Grades of CIN have characteristic appearances when stained with 5% acetic acid, the diagnosis is only confirmed histologically and therefore biopsy is useful,

31
Q

Exceptions for routine cervical screening

A
  • 25 to 64 with renal failure requiring dialysis must haver cervical cytology after diagnosis
    -All women with HIV should have cervical surveillance, annual cytology should be performed with an initial colposcopy
  • In organ transplant recipients
32
Q

HPV

A

Cervical cancer is mostly caused by HPV 16,18 which causes 70% of cervical cancer

33
Q

Malignant disease of the cervix investigations

A
  • To confirm the diagnosis, the tumour is biopsied.
  • To stage the disease, vaginal and rectal examination is used to asses the size of the lesion and parametrial or rectal invasion.
  • Unless it is clearly small, examination under anaesthetic is performed. Cystoscopy detects bladder involvement and MRI detects tumour size, spread and LN involvement.
  • To assess the patient’s fitness for surgery, a CXR, FBC, U&Es are checked. These may be abnormal with advanced disease. Blood is cross-matched before surgery
34
Q

Cervical intraepithelial neoplasia (CIN) staging

A
  • CIN 1 – changes only in lower 1/3rd of squamous epithelium, low grade, but changes can be difficult to differentiate from reactive changes only. spontaneous regression rates are over 50% in about 22 months.
  • CIN 2 and 3 – changes in lower 2/3 rd and whole of the squamous epithelium respectively. Higher grade abnormality, regression rates are lower.
  • CIN 2 – regression rate is 50% to 60%, therefore in nulliparous women conservative management can be offered with more regular surveillance.
  • CIN 3 – treatment options offered as further progression leads to cancer.
35
Q

HPV vaccine

A
  • Offered to all 12-13 year old, cut cervical cancer by 90%
  • Current brand: Gardasil 9 covers HPV 6, 11, 16, 18, 31, 33. 45, 52
36
Q

Oligohydramosis
