25
What is the most likely locations of endometriosis?
Usually ovary, pouch of Douglas, pelvic peritoneum
26
Theories of pathogenesis of endometriosis?
> Retrograde menstruation > Coelomic metaplasia > Haematogenous spread > Direct transplantation
27
Symptoms of endometriosis?
``` > Can be asymptomatic > Premenstrual pelvic pain, > Dysmenorrhoea, > Deep dyspareunia, > Sub-fertility ```
28
Signs of endometriosis?
> May be none > Tender nodules in rectovaginal septum > Limited uterine mobility > Adnexal mass
29
Diagnosis of endometriosis?
> Gold standard - laparoscopy - clear, red (Red-flame), bluish black or white lesions, powder burn nodule > MRI for deep endometriosis > Ultrasound can diagnose endometriosis (chocolate cyst)
30
What commonly happens in ovarian endometriosis and helps with diagnosis?
"Chocolate cysts" which can be seen laparoscopically and on US
31
How do we treat endometriosis?
> Medical (hormonal treatment and analgesics) > Surgical Disease may reoccur after treatment
32
How do we treat endometriosis - medically?
Medical (hormonal treatment and analgesics): 1) Progestogen - oral/injection/ Levonorgesterel Intrauterine system (LNG-IUS) 2) Combined oral contraceptive pill 3) GnRH analogues (eg leuprorelin) 4) (danazol/gestrinone no longer used) Disease may recur after treatment
33
How do we treat endometriosis - Surgically?
Surgical: 1) Excision of deposits from peritoneum/ovary 2) Diathermy / laser ablation of deposits 3) Removal of ovaries with or without hysterectomy Disease may recur after treatment
34
What is adenomyosis?
Characterised by the presence of endometrial tissue in the myometrium
35
Symptoms and signs of adenomyosis?
1) Heavy painful periods 2) Bulky tender uterus 3) Usually in parous women 4) May co-exist with endometriosis
36
Diagnosis of adenomyosis?
Diagnosis: > MRI may suggest diagnosis but limited availability > Histology of uterine muscle – generally post hysterectomy
37
Treatment of adenomyosis?
1) Treat symptoms of heavy and painful periods with hormonal contraception: > LNG IUS (Mirena) > Progestogens > Combined oral contraceptive pill 2) Often failed medical treatment/ endometrial ablation and diagnosed on pathology at hysterectomy
38
What are fibroids?
Smooth muscle growths also known as leiomyoma
39
How common are fibroids?
> Very common and usually asymptomatic > Up to 60% of 40 year olds have fibroids of varying size > Higher incidence in Afro-caribbean women
40
How are fibroids diagnosed?
Diagnosis: > Clinical exam – irregularly enlarged uterus > Ultrasound > Hysteroscopy (if inside uterine cavity)
41
Types of fibroids?
1) Sub mucous = Protrude into uterine cavity 2) Intramural = Within uterine wall 3) Sub serous = Project out of uterus into peritoneal cavity
42
Types of fibroids - Sub-mucous?
Sub-mucous = Protrude into uterine cavity
43
Types of fibroids - ?
Intramural = Within uterine wall
44
Types of fibroids - Sub-serous?
Sub-serous = Project out of uterus into peritoneal cavity
45
Diagnosis of fibroids?
> Ultrasound > Hysteroscopy > Laproscopy
46
Symptoms of fibroids?
> May be asymptomatic > Large fibroids may cause pressure symptoms (depends on location) > Menorrhagia: enlarge the uterine cavity surface area > Submucous or fibroid polyps may cause intermenstrual bleeding > Can rapidly increase in size in pregnancy causing pain, malpresentation or obstruction in labour (cervical fibroid)
47
Treatment of fibroids?
1) Standard menorrhagia treatment if cavity not too distorted 2) GnRH analogues or Ulipristal acetate may be used temporarily to shrink the fibroids – usually preoperatively 3) Submucous fibroids: Transcervical resection 4) Hysteroscopically 5) Myomectomy 6) Uterine artery embolisation 7) Hysterectomy
48
Treatments for Dysfunctional Uterine Bleeding?
Medical treatment: 1) Non hormonal: > Tranexamic acid > Mefanamic acid 2) Hormonal: > Progestogen only tablets, injections (Depo Provera) > Levonorgesterel Intrauterine System > Combined pill ``` Surgical treatment (if family complete): > Endometrial ablation > Hysterectomy ```
49
Treatments for Dysfunctional Uterine Bleeding - Medical treatment?
Medical treatment: 1) Non hormonal: > Tranexamic acid > Mefanamic acid 2) Hormonal: > Progestogen only tablets, injections (Depo Provera) > Levonorgesterel Intrauterine System > Combined pill
50
Treatments for Dysfunctional Uterine Bleeding - Surgical treatment?
``` Surgical treatment (if family complete): > Endometrial ablation > Hysterectomy ```
51
Treatments for Dysfunctional Uterine Bleeding - Medical treatment - Non-hormonal?
1) Tranexamic acid (antifibrinolytic) reduces blood loss 60% 2) Mefenamic acid (prostaglandin inhibitor) reduces blood loss 30% and pain > Both of them are taken at the time of periods > Suitable for those trying to conceive > Do not regulate cycles
52
Treatments for Dysfunctional Uterine Bleeding - Medical treatment -Tranexamic acid?
Tranexamic acid (antifibrinolytic) reduces blood loss 60%
53
Treatments for Dysfunctional Uterine Bleeding - Medical treatment - Mefenamic acid?
Mefenamic acid (prostaglandin inhibitor) reduces blood loss 30% and pain
54
Treatments for Dysfunctional Uterine Bleeding - Medical treatment - Hormonal?
1) Combined contraceptive pill makes periods lighter, regular and less painful 2) LNG IUS and Depo-Provera reduces bleeding – may cause irregular bleeding, some women will be amenorrhoeic 3) Oral progestogens eg Provera10mg od: - Day 5-25 cycle reduce bleeding +regulate - Day 15-25 may regulate cycle but does not reduce amount of bleeding
55
Treatments for Dysfunctional Uterine Bleeding - Medical treatment - Combined contraceptive pill?
Combined contraceptive pill makes periods lighter, regular and less painful
56
Treatments for Dysfunctional Uterine Bleeding - Medical treatment - LNG IUS and Depo-Provera?
LNG IUS and Depo-Provera reduces bleeding – may cause irregular bleeding, some women will be amenorrhoeic
57
Treatments for Dysfunctional Uterine Bleeding - Medical treatment - Oral progestogens eg Provera10mg od?
- Day 5-25 cycle reduce bleeding +regulate | - Day 15-25 may regulate cycle but does not reduce amount of bleeding
58
Treatments for Dysfunctional Uterine Bleeding - Surgical treatment - Endometrial ablation?
Permanent destruction of endometrium using different energy sources 60% will have no periods, 85% are satisfied, 15% will have subsequent hysterectomy
59
Treatments for Dysfunctional Uterine Bleeding - Surgical treatment - Endometrial ablation - first generation?
First generation ablation: under hysteroscopic vision – uses diathermy
60
Treatments for Dysfunctional Uterine Bleeding - Surgical treatment - Endometrial ablation - second generation?
Second generation ablation: thermal balloon, radiofrequency
61
Pre-requisites for endometrial ablation?
> Uterine cavity length <11 cm > Submucous fibroids < 3cm > Previous normal endometrial biopsy
62
What is a hysterectomy?
Surgical removal of uterus
63
Types of hysterectomy approach?
1) Abdominal 2) Vaginal 3) Laparoscopic: > Laporoscopically assisted vaginal hysterectomy (LAVH) > Laparoscopic hysterectomy > Total laparoscopic hysterectomy TLH > Laparoscopically assisted subtotal hysterectomy
64
What is a total hysterectomy?
Total hysterectomy: cervix and uterus removed
65
What is a subtotal hysterectomy?
Subtotal hysterectomy: uterus removed, cervix left
66
Types of hysterectomy?
1) Subtotal 2) Total 3) Total with bilateral sapling-oophorectomy 4) Wartheim's hysterectomy
67
How many days in hospital are required for hysterectomy?
> 3-5 days in hospital > 1-2 days laparoscopic approach > 2-3 months recovery
68
What are the risk of a hysterectomy?
1) Infection 2) DVT 3) Bladder, bowel, vessel injury 4) Altered bowel functions 5) Adhesion Guarantees amenorrhoea
69
What is the removal of the ovaries with uterus called?
Salpingo-oophorectomy
70
When may sapling-oophprectomy be performed?
