Q

What are the investigations done to diagnose endometriosis?

A

Laparoscopy
MRI
USS endometrioma

24
Q

What is the medical treatment of endometriosis?

A

Progestogen - oral, injection or Mirena IUS, coil will have fewer general side-effects
Combined pill or patch for 3 months (9 weeks) at a time
GnRH analogues e.g. leuprorelin

25
Q

What is the surgical treatment of endometriosis?

A

Laparoscopic excision of deposits from peritoneum/ovary
Diathermy/laser ablation of deposits
Hysterectomy alone won’t treat endometriosis as ovaries are still there producing hormones, so combined hysterectomy and oophorectomy

26
Q

What is adenomyosis?

A

Endometrial tissue found deep in the myometrium
Heavy painful periods
Bulky tender uterus

27
Q

How is adenomyosis diagnoses?

A

USS - probably normal
Laparoscopy - normal
Hysteroscopy - normal
MRI may suggest diagnosis but limited availability
Histology of uterine muscle - not endometrial biopsy

28
Q

What is the treatment of adenomyosis?

A

Mirena may help

Often failed medical treatment/ablation and diagnosed on pathology at hysterectomy

29
Q

What are fibroids?

A

Smooth muscle benign tumours - leiomyoma
Benign
Common, usually asymptomatic

30
Q

What percentage of fibroids are leiomyosarcoma?

A

0.01%

31
Q

What percentage of 40 year olds have fibroids?

A

60%

32
Q

In what ethnic group is there a higher incidence/younger age of fibroids?

A

Afro-Caribbean women

33
Q

How are fibroids diagnosed?

A

Clinical exam
Ultrasound
Hysterectomy

34
Q

What are the types of fibroid?

A

Submucous - protrude into uterine cavity
Intramural - within uterine wall
Subserous - project out of uterus into peritoneal cavity

35
Q

What are the symptoms of fibroids?

A

May cause pressure symptoms if large
May cause menorrhagia if they cause enlargement of uterine cavity surface area
Intermenstrual bleeding if submucous or polyp
Asymptomatic
May grow fast in pregnancy and cause pain, malpresentation and obstruction

36
Q

What is the treatment of fibroids?

A

No treatment if incidental finding and asymptomatic
Standard menorrhagia treatment if cavity is not too distorted
GnRH analogues for temporary shrinkage/preparation
Ulipristal oral treatment (antiprogestogen)
Transcervical resection of submucous fibroids
Myomectomy
Uterine artery embolisation
Hysterectomy

37
Q

What are the disadvantages of myomectomy?

A

Risk of haemorrhage and hysterectomy

Need Caesarean section if pregnancy occurs after due to risk of uterine rupture

38
Q

What is the treatment for dysfunctional uterine bleeding?

A

Reassure patients that there is no sinister pathology
Fertility-conserving treatment - non-hormonal or hormonal tablets, progestogen, IUD, Mirena
Endometrial ablation or hysterectomy if family is complete

39
Q

What are the fertility conserving treatments?

A

Tranexamic acid - reduces blood loss by 60% but does not regulate cycle (anti-fibrinolytic)
Mefenamic acid - reduces blood loss by 30% and pain but does not regulate cycle (prostaglandin inhibitor)
Combined contraception reduces bleeding, pain and regulates cycle
Mirena progestogen IUD reduces bleeding (initial 3-4 months irregular bleeding)
Oral progestogens e.g. Provera 10mg od, day 5-25 of cycle, reduces bleeding and regulates, day 15-25 may regulate cycle but does not reduce amount of bleeding

40
Q

What is endometrial ablation?

A

One-off removal of endometrium to below the basal layer
Can use diathermy/thermal balloon
Not possible if grossly distorted cavity or thin myometrium at CS scar
Treatment done through cervix

41
Q

What is the recovery time from endometrial ablation?

A

approx 1 week

42
Q

What is the effect of endometrial ablation on ovarian hormones and bladder?

A

No effect

43
Q

What percentage of women following endometrial ablation;

  • have no periods
  • are satisfied with treatment
  • go on to have hysterectomy?
A

60% have no periods
85% satisfied
15% go on to have hysterectomy

44
Q

What is hysterectomy?

A

Surgical removal of uterus

45
Q

What are the routes for hysterectomy?

A

Vaginal or abdominal

46
Q

What are the types of surgical procedures that can be done when performing hysterectomy?

A

Laparoscopically assisted vaginal hysterectomy
Total laparoscopic hysterectomy
Laparoscopically assisted subtotal hysterectomy

47
Q

What is a total hysterectomy?

A

Cervix and uterus removed

48
Q

What is a subtotal hysterectomy?

A

Uterus removed, cervix left

49
Q

What is a salpingo-oophorectomy?

A

Removal of Fallopian tubes and ovaries

50
Q

What do you need to do if ovaries are removed?

A

Immediate menopause - need to give HRT until age 50 to minimise risk of subsequent cancer

51
Q

What symptoms will persist if the ovaries are not removed?

A

Pre-menstrual symptoms and ovarian pain

52
Q

How many days are spent in hospital after open or vaginal hysterectomy?

A

3-5

53
Q

How many days are spent in hospital after laparoscopic hysterectomy?

A

2-3

54
Q

What is the recovery time from hysterectomy?

A

2-3 months full recovery

55
Q

What are the risks of hysterectomy?

A

Infection
DVT
Bladder/bowel/vessel injury
Altered bladder function and adhesions
