Q

Describe the progressive pathology of endometriosis to a frozen pelvis

A

Endometriosis causes inflammation, with progressive fibrosis, adhesions. In it’s most severe form, the entire pelvis is ‘frozen’, the pelvic organs rendered immobile by adhesions.

Q

How does endometriosis spread?

A

Most in the pelvis through retrograde menstruation. More distant foci may result from mechanism, lymphatic or blood-borne spread.

Q

What is retrograde menstruation?

A

Endometrium flows backwards through the fallopian tubes and into the abdomen, instead of leaving the body as a period The tissue then embeds itself on the organs of the pelvis and grows

Q

Why does retrograde menstruation not cause endometriosis in everyone?

A

happens in many women - not all have endometriosis. Thought to be a genetic predisposition. An unpopular theory is that endometriosis is the result of metaplasia of coelomic cells

A

If adenomysosis is suspected, to visualise peritoneal endometriosis, if there is clinical evidence of deeply infilitrating endometriosis, urteric, bladder and bowel involvement

Q

Does asymptomatic endometriosis require treatment?

A

Not usually - but could consider removing endometriomas in low risk of misdiagnosing ovarian cancer

24
Q

What are the broad treatment options of endometriosis?

A

Analgesia - NSAIDs, paracetamol, opiate
Hormonal treatments - COC 3-6 month trial in those not wanting to concieve
Progesterons for those not wanting to take hormonal contraceptive
HRT in woman taking GnRH
IUS
Surgery

25
How does GnRH and HRT help in endometriosis?
Gonadotrophin-releasing hormone analogues + HRT induce temporary menopausal state Overstimulation of the pituitary = down regulation of its GnRH receptors Pituitary gonadotrophin and therefore ovarian hormone production are inhibited
26
What are the side effects of GnRH and HRT in endometriosis?
Mimic menopause: reversible bone demineralisation limits therapy to 6 month, but can be extended up to 2 years with add-back HRT (prevents bone loss and menopausal SE)
27
What are the surgical options for the treatment of endometriosis?
Laparoscopic laser ablation diathermy/ scissors/ adhesiolysis Hysterectomy and bilateral salpinoophorectomy
28
Discuss laparoscopic laser ablation of endometriotic lesions
Can be used to destroy endometriotic lesions Surgery can improve conception rates therefore preferable to medical treatment in whose with endometriosis-related infertility More radical includes diseection of adhesions and removal of ovarian endometriomas
29
Discuss hysterectomy treatment of endometriosis
Last resort HRT is required if ovaries are removed and can occasionally cause reactivation if endometriosis returns HRT containing both oestrogen and progresterone is given to avoid prolonged unopposed oestrogen stimulation, linked with development of malignancy change in ectopic endometrium
30
Why can surgery be difficult in endometriosis?
Severity of adhesions, anatomic distortion - risk of damaging bowel, bladder, blood vessels and ureters
31
Why can surgical options sometimes be preferable to medical in endometriosis?
Symptomatic improvement in 70% - longer term than medical therapy, medical treatment in 80-90% of patients, however symptoms come back when treatment is stopped
32
In how many women does endometriosis regress or not progress?
>50%
33
Is fertility affected in endometrosis?
Yes - 25% of cases are found incidentally on laparoscopy for infertility
34
What is the prognosis like in endometrisos?
In 5 years after surgery/ medicine 20-25% of women will have a recurrence
35
Who is more likely to get PID?
Younger, poorer, sexually active (no condoms), nulliparous women
36
What is the pathology of PID?
Ascending infection from the vagina/ cervix causing an infection in the upper female genital tract
37
Which contraceptives are protective of PID?
COP and Mirena IUS are partly protective
38
How can treatments contribute to PiD?
Uterine instrumentation can spread previously asymptomatic STIs Complications of childbirth and miscarriage
39
What pathogens commonly cause PID?
Frequently polymicrobial | Chlamydia in up to 60%, gonnorrhea
40
Discuss fits-hugh-curtis syndrome in PID?
Periheptatis in 10% and causes RUQ pain due to adhesions, early visible at laparoscopy, between the liver and anterior abdominal wall
41
Describe some symptoms of PID
- Commonly asymptomatoc - Bilateral lower abdomen pain and deep dyspareunia - abnormal bleeding or discharge - can feel feverish and malaise in acute infective phase - Late presentation: fertility problems or menstrual problems
42
Describe some examination findings of PID
``` In severe cases - tachycardia, high fever, signs of lower abdominal peritonism and bilateral adnexal tenderness and cervical excitation (pain on moving the cervix) A mass (pelvic abscess) may be palpable vaginally ```
43
think of some differential diagnosis for PID (aka causes of bilateral abdo pain)
- appendicitis (unilateral pain) - ovarian cyst accidents (unilateral pain) - ectopic pregnancy (+ve PT, unilateral pain)
44
Discuss how you would investigate a patient for PID
- pregnancy test (to exclude ectopic pregnancy) - endocervical swaps to culture for chalamdyia and gonococcus (and their antibiotic sensitivity) - blood cultures if fever is present - bloods - WBC and CRP may be raised in acute infection - Pelvic USS - may exclude an abscess or ovarian cyst - Gold Standard: Laparoscopy with fimbiral biopsy and culture = not commonly done because invasive
45
Discuss management for PID
Mild disease can be managed in community, severe infection and fever needs hospital admission and IV therapy Analgesics Antibiotics Possible referal to GUM and partner notification
46
Describe the antibiotic treatment for PID
Ceftriaxone 500mg IM | followed by doxycycline 100 mg orally twice daily and metronidazole 400 mg twice daily for 14 days
47
What's the alternative antibiotic regime for PID
An alternative regime is oral ofloxacin 400 mg twice daily and oral metronidazole 400 mg twice daily for 14 days
48
In febrile PID patients, Iv therapy is recommended, what is this antibiotic regime?
Initial treatment is with doxycycline, single-dose IV ceftriaxone and IV metronidazole, then change to oral doxycycline and metronidazole to complete 14 days of treatment.
49
Describe some of the complications of PID
- formation of an abscess - tubal obstruction, subfertility - chronic infection and pelvic pain - ectopic pregnancy 6 x more common after PID - tubal damage (12% after 1 episode of PID)
50
Describe the pathology of chronic pelvic inflammatory disease
Chronic PID describes a persisting infection due to inadequate treatment of acute PID There are normally dense pelvic adhesions, fallopian tubes are obstructed and dilated with fluid (hydrosalpinx) or pus (pyosalpinx)
51
Describe the symptoms of chronic PID
- chronic pelvic pain - dysmenorrhoea - deep dyspareunia - heavy and irregular menstruation - chronic vaginal discharge - subfertility
52
What might you find on examination in someone with chronic PID
- abdo and adnexal tenderness and a fixed retroverted uterus
53
Does transvaginal ultrasound have a place in chronic PID?
Yes - transvaginal USS may show fluid collections within the fallopian tubes or surrounding adhesions
54
What is the best diagnostic tool for chronic PID?
Laparoscopy
55
Will a culture grow from chronic PID?
Culture is often negative
56
What is the treatment of chronic PID?
- analgesics - antibiotics if there is evidence of active infection - severe cases: cutting of adhesions (adhesioloysis) or removal of affected tubes may be required
