What other imaging is useful in endometriosis?

Q

Treatment for endometriosis

A

Initial treatment: 3/12 trial (suitable in primary care) of simple analgesia + hormonal contraception (any method). (Recommended for 3-6m before laparoscopy by RCOG)

If this has failed:

  • Consider need surgical treatment
  • GnRH agonists with add back HRT
  • Aromatase inhibitors (letrozole - for rectovaginal endometriosis only if all other therapies fail)

Q

Role of pre-surgical hormone treatment in endometriosis

A

Doesn’t improve surgical outcomes but can be used as interim pain control

(But NICE recommend GnRH for 3/12 pre-surgery for deep endo)

Q

Treatments on fertility in endometriosis

A
  • Hormonal treatment does not improve fertility
  • Offer operative laparoscopy with CO2 laser vaporisation for stage 1/2 endometrial
  • Excision of endometriomas
  • Can consider surgery in stage 3/4 disease if it is thought it will improve pregnancy outcomes

Q

ART in women with endometriosis

A

Stage 1/2: IUI with controlled ovarian stimulation increases birth rate.

GnRH agonists for 3-6m prior to ART can improve clinical pregnancy rates in infertile women with endometriosis.

Management of IBS
- Avoid foods e.g. insoluble fibres, beans, fatty food, caffeine, chocolate and sugar substitutes and alcohol - Moderate exercise - 1st line: Antispasmodics - 2nd line: TCAs/SSRIs - Laxatives/antidiarrhoeals (ondansetron can control diarrhoea in pt with IBS) - CBT, Hypnotherapy - Pregabalin

Retained ovary becomes buried in dense adhesions?
35
Rome III criteria for IBS
- COntinuous/recurrent abdo pain - At least 3 days per month in last 3 months - Onset at least 6 months previously Associated with two of: - Improvement with defaecation - Onset associated with change in frequency of stool - Onset associated with change in form of stool
36
Number of negative laparoscopies in patients with chronic pelvic pain
1/3-1/2
37
Incidence of bladder pain syndrome
2.5-6.5%
38
Definition of bladder pain syndrome
Pelvic pain, pressure or discomfort perceived to be related to the bladder, lasting for at least 6 months (new definition: 6 weeks) and accompanied by at least one other urinary symptom in the absence of other identifiable cause.
39
What makes bladder pain syndrome worse/better?
Worsens with certain food/drink Worsens with bladder filling Improves with urination
40
Diagnosis of bladder pain syndrome
- Diagnosis of exclusion. - Bladder diary, food diary. - Urine dipstick (consider testing ureaplasma/chlamydia if symptomatic sterile pyuria) - Urine cytology and cystoscopy if suspect malignancy - Bladder biopsy and hydrodistension NOT recommended to make diagnosis
41
Management of bladder pain syndrome
1st line: Analgesia, stress relief, diet, physical therapy 2nd line: Amitryptiline, Cimetidine (if fails refer MDT/pain team/psychologist) 3rd line: Intravesical DMSO, heparin, botox A, lidocaine chondroitin sulfate, hyaluronic acid. 4th line: Neuromodulation (posterior tibial N, sacral N), oral ciclosporin A 5th line: Cystoscopy and hydrodistension
42
Effect of pregnancy of BPS
Unkown
43
BPS treatments which are safe in pregnancy
Oral amitryptiline\ Intravesical heparin One course of intravesical DMSO pre-pregnancy
44
Classification of BPS
Cystoscopy with hydrodistension: - Not done: X - Normal: 1 - Glomerulations: 2 - Hunner Lesions: 3 Biopsy: - Not done: X - Normal: A - Inconclusive: B - +ve: C
45
Incidence of pelvic congestion syndrome
3.8%
46
Who gets pelvic congestion syndrome?
Premenopausal multiparous women
47
What happens in pelvic congestion syndrome?
Ovarian plexus varicosities secondary to: - Absence of ovarian vein valves allowing reflux - Venous dilatation in pregnancy leading to valvular incompetence - Compression of left renal vein (into which ovarian vein drains) between SMA and aorta ("nutcracker syndrome")
48
Characteristic features of pelvic congestion syndrome
Pelvic pain which is worse premenstrually, in pregnancy and when standing. Throbbing ache after intercourse.
49
Investigations for pelvic congestion syndrome
Gold standard is venography. | Can use USS/CT/MRI.
50
Management of pelvic congestion syndrome
``` Analgesia Responds to ovarian suppression Daflon is a vasoconstrictive drug with benefit Surgical Embolisation Psychotherapy ```
