Management of endometriosis

This document discusses the management of endometriosis. It defines endometriosis as tissue similar to the endometrium found outside the uterus, causing inflammation. Common symptoms include severe menstrual pain, pain during or after sex, chronic pelvic pain, and infertility. Diagnosis is typically via laparoscopy, which allows visualization and staging of lesions. Treatment involves surgery to remove lesions and adhesions or drain endometriomas, along with medical therapy using hormones to suppress the endometrial tissue. Goals of treatment are pain relief and improving fertility.

Management of endometriosis Associate Professor Dr. Anisah Jalaluddin
Endometriosis is defined as the presence of endometrial-like tissue outside the uterus, which induces a chronic, inflammatory reaction.
Which symptoms are typically associated with endometriosis? • severe dysmenorrhoea • deep dyspareunia • chronic pelvic pain • ovulation pain • cyclical or perimenstrual symptoms, such as bowel or bladder, with or without abnormal bleeding or pain • infertility • chronic fatigue • dyschezia (pain on defaecation).
Sign • Deeply infiltrating nodules are most reliably detected when clinical examination is performed during menstruation. • Pelvic tenderness • Fixed, retroverted uterus • Tender uterosacral ligaments or • Enlarged ovaries
Physical sign
What is the ‘gold standard’ diagnostic test? Visual inspection of the pelvis at laparoscopy • diagnostic laparoscopy is associated with an approximately 3% risk of minor complications, such as nausea or shoulder tip pain, and • a risk of major complications, such as bowel perforation, vascular damage, of between 0.6/1000 and 1.8/1000 • should not be performed during or within 3 months of hormonal treatment, to avoid under-diagnosis • Appearance: blackened spot, red implants, vesicles. Peritoneal defects and endometriomas.

Surgically, endometriosis can be staged I–IV (Revised Classification of the American Society of Reproductive Medicine).[42] but it is important to note staging assesses physical disease only, not the level of pain or infertility. A patient with Stage I endometriosis may have little disease and severe pain, while a patient with Stage IV endometriosis may have severe disease and no pain or vice versa. In principle the various stages show these findings: Stage I (Minimal) Findings restricted to only superficial lesions and possibly a few filmy adhesions Stage II (Mild) In addition, some deep lesions are present in the cul-de-sac Stage III (Moderate) As above, plus presence of endometriomas on the ovary and more adhesions. Stage IV (Severe) As above, plus large endometriomas, extensive adhesions. Endometrioma on the ovary of any significant size (Approx. 2 cm +) must be removed surgically because hormonal treatment alone will not remove the full endometrioma cyst, which can progress to acute pain from the rupturing of the cyst and internal bleeding.
How reliable is imaging for diagnostic purposes? • transvaginal ultrasound (TVS) has limited value in diagnosing peritoneal endometriosis but it is a useful tool both to make and to exclude the diagnosis of an ovarian • there is insufficient evidence to indicate that magnetic resonance imaging (MRI) is a useful test to diagnose or exclude endometriosis compared to laparoscopy.
MRI Ultrasound
How reliable is serum CA125 measurement for diagnostic purposes? • Serum CA125 levels may be elevated in endometriosis. However, compared with laparoscopy, measuring serum CA125 levels has no value as a diagnostic tool. • The estimated sensitivity was only 28% for a specificity of 90%.
Treatment of Endometriosis Management of pain • Surgery • Medical therapy Treatment of infertility • Surgery • Ovulation induction • Assisted reproductive technology
Medical treatment of endometriosis- associated pain
Treatment of Pain • Medical management • Oral contraceptives, progesterone, danazol • GnRH agonist with add-back • Alternating GnRH agonist and OCs • Aromatase inhibitors - letrozole • NSAID
CHOICES OF MEDICAL THERAPY Drug group Example Side effects 1 Progestogens Medroxyprogesterone Duphaston Norculot Mood swing Nausea bloatedness 2 Danazol (synthetic androgen) Danocrine Hoarseness Hirsuitism, acne 3 Oral contraceptives Any OCPs Weight gain, bloatedness 4 GnRH analogue Zoladex (Goserelin) Lucrin Vasomotor symptoms/ osteoporosis
• COCPs act by ovarian suppression. Initially, a trial of continuous or cyclic COCPs should be administered for 3 months. • All progestational agents act by decidualization and atrophy of the endometrium. • Duphaston - 10mg bd or tds - from day 5 to day 25 cycle Or Continuously for 6 – 9 months • GnRH analogues produce a hypogonadotrophic-hypogonadic state by downregulation of the pituitary gland. • Goserelin and leuprolide acetate are the commonly used agonists. • Danazol acts by inhibiting the midcycle follicle-stimulating hormone (FSH) and luteinizing hormone (LH) surges and preventing steroidogenesis in the corpus luteum. It is the most extensively studied agent for endometriosis. • The recommended dose is 600-800 mg/d
Empirical treatment of pain symptoms without a definitive diagnosis • Therapeutic trial of a hormonal drug to reduce menstrual flow is appropriate. • It include counselling, adequate analgesia, progestogens or the combined oral contraceptive. It is unclear whether the combined oral contraceptives should be taken conventionally, continuously or in a tricycle regimen. • A gonadotrophin-releasing hormone (GnRH) agonist may be taken but this class of drug is more expensive and associated with more adverse effects and concerns about bone density.
How effectively do nonsteroidal anti-inflammatory drugs (NSAIDs) treat endometriosis-associated pain? • There is inconclusive evidence to show whether NSAIDs (specifically naproxen) are effective in managing the pain. Is there a role for the levonorgestrel intrauterine system (LNG-IUS)? • The LNG-IUS appears to reduce endometriosis-associated pain.
Surgical treatment of endometriosis- associated pain
Management of Pain • Surgical treatment • Ablation of endometrial implants • Lysis of adhesions • Ablation of uterosacral nerves • Resection of endometriomas • Combined surgical and medical treatment
Surgical care can be broadly classified as • conservative when reproductive potential is retained • semiconservative when reproductive ability is eliminated but ovarian function is retained • radical when the uterus and ovaries are removed.Age, desire for future childbearing, and deterioration of quality of life are the main considerations when deciding on the extent of surgery.
How should ovarian endometriomas be managed? • Laparoscopic cystectomy for ovarian endometriomas is better than drainage and coagulation. • The recurrence of endometriomas and symptoms are reduced by excisional surgery more so than drainage and ablation. • Is there a role for hormonal treatment after surgery? • Postoperative hormonal treatment has no beneficial effect on pregnancy rates after surgery. • Compared with surgery alone or surgery plus placebo, postoperative hormonal treatment has no effect on pregnancy rates.

When should surgical treatment be considered? • Ideal practice is to diagnose and remove endometriosis surgically. Does surgical treatment relieve pain? • Ablation of endometriotic lesions reduces endometriosis- associated pain compared with diagnostic laparoscopy. Does nerve ablation provide pain relief? • itself does not reduce endometriosis-associated pain. • presacral neurectomy,especially in severe dysmenorrhoea, although the evidence is inconclusive.44
What is the role of more radical surgery? • Endometriosis associated pain can be reduced by removing the entire lesions in severe and deeply infiltrating disease. • If a hysterectomy is performed, all visible endometriotic tissue should be removed at the same time. • Bilateral salpingo-oophorectomy may result in improved pain relief and a reduced chance of future surgery.
Is there a role for surgical treatment of endometriomas before IVF? • Laparoscopic ovarian cystectomy is recommended for endometriomas ≥ 4 cm in diameter. • to confirm the diagnosis histologically; reduce the risk of infection; improve access to follicles, and possibly improve ovarian response and prevent endometriosis progression The woman should be counselled regarding the risks of reduced ovarian function after surgery and the loss of the ovary.The decision should be reconsidered if she has had previous ovarian surgery.
The role of complementary therapies in relieving endometriosis-associated pain is unclear. • Many women with endometriosis report that nutritional and complementary therapies such as homeopathy, reflexology, traditional Chinese medicine or herbal treatments, do improve pain symptoms. • While there is no evidence from randomised controlled trials in endometriosis to support these treatments, they should not be ruled out if the woman feels that they could be beneficial to her overall pain management and/or quality of life, or work in conjunction with more traditional therapies.
Long term management • Endometriosis is progressive and can result in chronic pain and infertility. Gynecologic follow-up is advised.

Case • A 37 year-old nulliparous lady, married for the last 7 years, complains of severe dysmenorrhoea of 10 years. She is also very anxious to conceive. Examination revealed a tender left iliac fossa with a tender mass which has restricted mobility. Pelvic examination confirms a retroverted uterus with mobility and a tender mass in the left iliac fossa.
Key points • Endometriosis is a common disease affecting women of the reproductive age group (10%). It may begin in late adolescence. Symptom – dysmenorrhoea and infertility. • Pelvic endometriosis causes scarring, fibrosis and adhesions. • There is a role of medical management in mild stage of endometriosis • The surgical intervention is indicated in moderate to severe endometriosis
