Q

When should salpingostomy be considered over salpingectomy for removing an ectopic and why

A

Salpingostomy should be considered for women with contralateral tube damage, as this is a risk factor for infertility

Q

Describe a missed miscarriage (presentation, cervical Os, USS findings)

A
  • asymptomatic
  • Os: closed
  • USS: nonviable pregnancy, retained products with no fetal heartbeat or empty gestational sac
20
Q

Describe an inevitable miscarriage (presentation, cervical Os, USS findings)

A
  • Pv bleeding and abdo pain +/- intact membranes
  • Os: open
  • USS: gestational sac in the uterus without fetal HB or other signs of a non-viable pregnancy.
21
Q

How is a miscarriage managed conservatively

A
  • allow miscarriage to occur spontaneously
  • bHCG - decrease of >50% in 48h indicates early pregnancy loss
  • repeat UPT in 3 weeks to confirm miscarriage is complete
  • follow up USS (1w) for threatened/ inevitable miscarriages
22
Q

Describe the medical management of a miscarriage

A
  • Mifepristone followed by misoprostol 48h later for missed miscarriage
  • single dose vagina misoprostol for others
  • analgesia
  • anti-emetics
  • UPT after 3w to confirm
23
Q

What are the two types of surgical management for a miscarriage

A
  • Manual vacuum aspiration under local anaesthetic
  • Electric vacuum aspiration under general anaesthetic
24
Q

Why is infection more common in an incomplete miscarriage

A

retained products of conception create a risk of infection
treat with abx

25
Q

What are molar pregnancies

A
  • chromosomally abnormal pregnancies that have the potential to become malignant (gestational trophoblastic neoplasia)
26
Q

What is a complete mole

A

occurs when a single sperm (90%) or two sperm cells fertilise an egg that has lost its DNA (“empty ovum”)

27
Q

What is a partial mole

A
  • occurs when two sperm cells fertilise a normal ovum (has DNA) at the same time
  • new cell now has three sets of chromosomes
28
Q

How is a molar pregnancy diagnosed, give findings

A
  • Pelvic ultrasound - irregular echobright area containing multiple cysts (snowstorm appearance)
  • serum hCG - significantly elevated for gestational age
  • large uterus for gestational age
29
Q

How does a molar pregnancy typically present

A
  • vaginal bleeding
  • first trimester with missed period
30
Q

How is a molar pregnancy managed

A
  • send POC for histology urgently to confirm
  • surgery - suction evacuation of uterus to remove mole
31
Q

Molar pregnancies are at an increased risk of developing into which cancer

A

choriocarcinoma - part of the gestational trophoblastic tumours

32
Q

What is ovarian torsion

A

Twisting of the ovary and/ or fallopian tube on its vascular and ligamentous supports

33
Q

Why is ovarian torsion an issue

A

It can block adequate blood flow to the ovary

34
Q

Give 3 ways ovarian torsion may present

A
  • severe pelvic/ abdo pain
  • N+V
  • diarrhoea
    (non- specific)
35
Q

What imaging should be done for a suspected ovarian torsion

A
  • urgent transvaginal ultrasound - enlarged ovary, free fluid, whirlpool sign
  • abdo/ transrectal USS for children/ pt who haven’t been sexually active
36
Q

How is ovarian torsion managed

A

laproscopic surgery
* immediate surgical detorsion
* salpingo-oophrectomy if ovary is non-viable

37
Q

What is the definitive diagnostic tool for ovarian torsion

A

Surgical visualisation

38
Q

What is pelvic inflammatory disease

A

Infection within the female reproductive system
* inc: endometrium, fallopian tubes, ovaries, uterus

39
Q

How might PID present

A
  • abnormal cervical/ vaginal discharge
  • lower abdo pain
  • dyspareunia
40
Q

PID can be diagnosed by clinical exam. Give 3 findings on pelvic examination.

A
  • uterine tenderness
  • cervical motion tenderness
  • adnexal tenderness (endometritis)
41
Q

Give 4 RFs of PID

A
  • unprotected sex
  • previous chlamydia, gonorrhoea or PID
  • Multiple sexual partners
  • IUD use
41
Q

How is PID investigated

A
  • STI screen
  • pregnancy test - exclude ectopic
  • CRP/ ESR - raised = support diagnosis
42
Q

What typically causes PID

A

Bacterial infection - mc STI
* Gonorrhoea
* chlamydia (mc)

43
Q

How is PID managed

A
  • Swabs to confirm causative agent
  • single dose IM ceftriaxone + PO doxycycline and metronidazole for 14 days
  • contact tracing
  • advice: avoid sex until patient and partner complete treatment
44
Q

What bacteria does each antibiotic cover in the treatment of PID

A
  • Ceftriaxone - gonorrhoea
  • doxycycline - chlamydia and mycoplasma genitalium
  • metronidazole - anaerobes eg. gardnerella vaginalis (bv)
