What is an important complication of chronic endometritis? What happens?

A

Asherman’s syndrome-

Intrauterine adhesions occur due to the inflammations of the endometrium. The basal layer is unable to regenerate the functional layer and leads to fibrosis and adhesions.

Q

What symptoms might a menopausal woman present with if she has developed endometrial cancer?

A

IMB

Heavier periods than normal

32
Q

What symptoms might a post menopausal woman present with if she has developed endometrial cancer?

A

PMB- any post menopausal bleeding requires further investigation as to the cause

33
Q

What is the most common cause of PMB?

A

Atrophic vaginitis- due to low oestrogen stats and small bleeds that occur. PMB always requires further assessment as to the cause as it may be due to malignancy

34
Q

What initial investigation should be done for PMB?

A

Transabdominal or transvaginal USS

35
Q

What endometrial thickness on USS in a post-menopausal woman indicates that endometrial sampling is needed?

A

> 4mm

<4mm has a 96% negative predictive value with no requirement for biopsy

36
Q

What are the two ways a biopsy sample may be obtained of the endometrium?

A

Endometrial sampling using a pipelle

Via hysteroscopy

37
Q

What information is required to stage a cancer?

A

Staging is done in order to assess the extent of spread of a cancer- therefore imaging is required either CT or MRI

38
Q

What is seen in stage 1 endometrial cancer?

A

Confined to the body of the uterus only

39
Q

What is seen in stage 2 endometrial cancer?

A

Spread to the cervix

40
Q

What is seen in stage 3 endometrial cancer?

A

Advancing beyond the uterus into surrounding structures but still within the lesser/true pelvis

41
Q

What is seen in stage 4 endometrial cancer?

A

Extending outside the pelvis with distant metastases

42
Q

What treatment options exist for the treatment of endometrial cancer?

A

Surgery- hysterectomy, bilateral salpingo-oophorectomy (BSO), pelvic lymphadenectomy
Radiotherapy
Chemotherapy- e.g. paclitaxel, doxorubicin, cisplatin

Treatment is carried out within specialist cancer centres according to stage and grade of the cancer

43
Q

Why does PMB always require further assessment?

A

May be due to endometrial carcinoma

44
Q

Lecture on endometrial cancer

A

https://www.youtube.com/watch?v=3BuVJCtds4g

45
Q

Why should oestrogen only HRT not be given to women with a uterus?

A

The exposure to unopposed oestrogen increase the risk of endometrial cancer developing

46
Q

What cancer syndrome is endometrial cancer associated with?

A

Lynch Syndrome of HNPCC

Others- Ovarian, colon, other GI cancers

47
Q

What might be done to manage endometrial hyperplasia?

A

Remove the excess oestrogen source that is stimulating the hyperplasia- weight loss, HRT, PCOS
Progestogens- Mirena coil but this is a contraceptive and so oral progesterone may be taken for a short period of time instead (medroxyprogresterone acetate)

Re-biopsy in 6-12 months to check for response/investigate for cancerous change

48
Q

What are endometrial polyps?

A

Benign growth of the endometrium that protrude into the endometrial cavity

49
Q

What breast cancer medication is associated with an increased risk of endometrial polyps?

A

Tamoxifen- whilst it blocks oestrogen receptors at the breast it stimulates that endometrium

50
Q

What is pyometra? What is important to remember about it?

A

Pyometra is pus in the uterus

It is important to remember that 50% have underlying outflow obstruction due to cancer

51
Q

What is endometriosis?

A

Presence of endometrial tissue outside of the uterus

52
Q

What is adenomyosis?

A

Endometrial tissue within the myometrium

53
Q

What are some of the theories about the cause of endometriosis?

A

1) Retrograde Menstruation- leading to adherence, invasion and growth of tissue elsewhere
2) Impaired immunity following retrograde mensuration meaning the cells aren’t cleared by the immune response
3) Metaplasia of mesothelial cells that line the peritoneum
4) Metastasis of endometrial cells- travel to distant organs
5) Extrauterine stem cell theory- differentiate to endometrial cells within the bone marrow and travel to distal site

Exact cause isn’t known

54
Q

What is the mesothelium?

A

The epithelial lining of the pleura, peritoneum and pericardium

55
Q

What are some risk factors for endometriosis?

A

Family history
No pregnancy
Early menarche/Late menopause

(think more oestrogen and menstrual cycles)

56
Q

What causes the pain in endometriosis?

A

Like the endometrium the endometrial deposits bleed during the menstrual cycle. Bleeding into the abdomen generates an immune response and there is resulting pain that is cyclical in nature- prolonged inflammation leads to adhesions which can cause chronic pain

57
Q

What is an endometrioma?

A

This is also called a chocolate cyst- due to endometrial tissue within the ovaries causing dark collections of blood

58
Q

How might someone with endometriosis present?

A

Pelvic/lower abdominal pain
Cyclical pain that is worse with periods
Chronic pain if adhesions have formed
Severe dysmenorrhoea
Deep Dyspareunia- due to inflammation of uterosacral ligaments
Pain on defecation (dychezia)
May experience cyclical rectal bleeding if endometrial deposits present there
Sub-fertility due to prolonged inflammation

Symptoms depend upon the location of the endometrial cells

59
Q

Why might endometriosis cause cyclical rectal bleeding?

A

Due to endometrial deposits in the rectum

60
Q

What area of the pelvic may be involved to cause dyschezia in patients with endometriosis?

A

Pouch of Douglas- recto-vaginal pouch

61
Q

What is the gold-standard investigation for endometriosis?

A

Laparoscopy- with biopsy for histological confirmation

The extent of disease should be documented with photographs.

62
Q

What are the treatment options for endometriosis?

A

Medical- Stopping periods prevents the inflammatory process. COCP, Mirena Coil, GnRH Analogues (e.g. Gosrhelin with Tibolone HRT), NSAIDs for analgesia (e.g. Mefanamic acid)
Surgical Treatment- only if medical treatment has failed. Laparoscopy using ablation, excision of coagulation to destroy to deposits. Excision of endometriomas. Hysterectomy may be considered if completed family.

63
Q

What medical options are used to treat endometriosis?

A

Combined oral contraceptive
Mirema coil
GnRH analogues- Gosrhelin
NSAIDs for pain relief-

64
Q

What surgical options are available for the treatment of endometriosis?

A

Surgery is only considered for patients with endometriosis that has not responded to medical therapy

Excision, ablation or coagulation of the endometrial deposits

If completed family- hysterectomy may be considered

65
Q

What is a leiomyoma?

A

Also called a uterine fibroid- it is a benign tumour of the smooth muscle of the uterus

Their the most common type of intra-mural fibroids

66
Q

How can uterine fibroids be classified?

A

According to their location in the uterus

Subserosal- smooth muscle cells at the perimetrium
Submucosal- just below the endometrium
Intramural- within the myometrium
Pedunculated- submucosal fibroids that grow into the uterine cavity or extend into the abdominal cavity. They’re connected to the myometrium via a stalk.

67
Q

What ethnicity is most commonly affected by fibroids?

A

Afro-Caribean

68
Q

What is the relationship between fibroids and oestrogen levels?

A

Fibroids are oestrogen dependent and their growth rate increases when there is increased oestrogen levels, especially during pregnancy. Additionally the atrophy after menopause.

69
Q

What triggers large increases in fibroid size?

A

Pregnancy due to the increased levels of oestrogen

70
Q

What are some risk factors for fibroid development?

A

Afro-Caribbean
No pregnancies
Early menarche
Late menopause

(Similar risk factors for endometrial hyperplasia)

71
Q

How might fibroids present?

A

Menorrhagia- heavy periods due to increased SA of endometrium. Especially submucosal and pedunculated.
Fertility issues- due to difficulty with implantation and distortion of uterine cavity with submucosal fibroids.
Pain- torsion and red degeneration
Sx due to mass effect- varicose veins, DVT, urinary frequency

72
Q

What syndrome are fibroids associated with?

A

Reed’s syndrome

Skin and uterine fibroids
Aggressive papillary renal cell cancer

73
Q

What investigations might be done to investigate for fibroids?

A

Trans vaginal scan
Trans abdominal scan
Rarely biopsy if suspicious features

74
Q

What are the treatment options for fibroids?

A

Conservative- if small and asymptomatic the can be left alone
Medical- Mainly to shrink fibroids prior to surgery, GnRH Analogues (e.g. Gosrhelin), Ullipristal Acetate (progesterone receptor modulator)
Surgical- Myomectomy, Hysterectomy, Uterine artery embolisation by interventional radiologist

75
Q

What is the macro and microscopic appearance of fibroids?

A

Macro- round, firm and grayish white

Micro- whorled pattern of smooth muscle bundles with well defined borders

76
Q

What are some concerning features that might suggest leiomyosarcoma over leiomyoa?

A

Haemorrhage or necrosis
A single lesion- fibroids are typically multiple
Biopsy would show atypical cells with a high mitotic index
