ENDOMETRIOSIS, ADENOMYOSIS, DYSMENORRHEAGYNE ENDOMETRIOSIS, ADENOMYOSIS, DYSMENORRHEAMedical management: GnRH Agonist
- Specific suppression of gonadotrophin secretion down regulation & desensitization of the pituitary to produce extremely low levels of circulating estrogen
- Secondary diminution of ovarian steroidogenesis- Since endometrial tissue requires estrogen to grow,
endometriosis is temporarily halted- Induce temporary menopause by blocking estrogen production- Mainstay of endometriosis treatment today
GnRH agonist (Examples)- Leuprolide acetate (Lupron, injectable)o 3.75 – 7.5 mg IM per month
- Nafarelin acetate (Synarel, intranasal)o One spray (200 ug) in one nostril - AM, the other nostril – PM
- Goserelin acetate (Zoladex, subcutaneous implant)o 3.6 mg every 28 days
- Chronic use produces “medical oophorectomy” o (pseudomenopause or medical castration)
- Side effects: primarily associated with estrogen deprivation similar to menopauseo Hot flushes, vaginal dryness, insomnia
Reversible after discontinuing therapy – ovarian function will return to normal 6 – 2 weeks after 6 months of therapy
o No effect on sex hormone – binding globulins- No androgenic side effects- No significant changes in serum cholesterol, HDL or LDL- Currently, clinicians “add – back” therapyo Very low doses of estrogen (30 pg/ml of estradiol)o Low doses of progestins
- Both E & Po Begun after 2 – 3 months of GnRH agonist therapyo Makes side effects less bothersome without compromising the
agonist’s therapeutic effect o Diminish demineralization of bone (osteoporosis)
Medical management: Oral contraceptives- Monophasic oral contraceptive taken CONTINUOUSLY & not
intermittently- Amenorrhea is the desired end point in the therapy- Prolonged therapy causes endometrial gland & marked decidual
reaction of the stroma
Medical management: Other hormonal treatment- Progestins
Prolonged amenorrhea (endometrial atrophy)o Medroxyprogesterone acetate (MPA)
30 mg orally per dayo Depomedroxyprogesterone acetate (DMPA)
150 mg IM every 3 monthso Gestrinone
2.5 – 7.5 mg per week taken orally- RU 486
o Antiprogestin agent used to produce amenorrhea
Surgical therapy: ENDOMETRIOSIS- The foundation of treatment for MODERATE TO SEVERE
Endometriosis- Mandatory for:o Acute rupture of large endometriomaso Ureteral obstructiono Intestinal obstructiono Ovarian endometriomas > 2 cm.o Adnexal enlargements > 8 cm.
- Surgical management o Diagnosiso Therapeutic
- LAPAROSCOPYo Preferred surgery; shorter recovery period and reduction in
the extent of subsequent adhesions- LAPAROTOMY
Surgical therapy – ConservativeGOAL: restore the anatomy & physiology
- Removal of all macroscopic, visible areas of endometriosis with preservation of ovarian function
- Removal or destruction of implants- Removal of endometrioas- Lysis of adhesions- Resection of the utero – sacral ligaments- Presacral neurectomyo Relieves midline pain (dysmenorrheal & dyspareunia) onlyo Does not diminish pain in other areas of the pelvic
Surgical therapy: ENDOMETRIOSIS- Definitive surgery- TAH, BSO & removal of all visible endometriosis reserved foro Far – advanced diseaseo For whom fertility is NOT a considerationo Patients with pain that continues after medical & conservative
surgery
ADENOMYOSIS- ENDOMETROSIS INTERNAo Derived from aberrant glands of the basalis layer of the
endometriumo Usually diagnosed incidentally by the pathologist on histologyo Histogenesis of adenomyosis is DIRECT EXTENSION from the
endometrial lining
Pathology: ADENOMYOSIS- 2 distinct pathologic presentationo Diffuse involvement of both anterior & posterior walls of the
uterus Posterior wall is more involved The individual areas are not encapsulated
o Focal area or adenomyoma Results in asymmetric uterus May have a pseudocapsule
- Diagnostic criterion:o Endometrial glands & stromas more than one low- powered
field from the basal year of the edometrium- Hyperplasia & Hypertrophy of the myometriumo Produces the globular enlargement of the uterus
Clinical Diagnosis: ADENOMYOSIS- CLASSIC SYMPTOMS:o Secondary dysmenorrheal
Dyspareuniao Menorrhagiao Infertility
- Secondary dysmenorrhealo Become increasingly severe
When the gland tissue grows during the menstrual cycle and then at menses tries to slough, the old tissue and blood cannot escape the uterine muscle and flow out of the cervix as part of normal menses.
This trapping of the blood and tissue causes uterine pain in the form of monthly menstrual cramps
o Dyspareunia Midline in location, deep pain in the pelvis
o Menorrhagia Produces abnormal uterine bleeding when some of the
blood finally escapes the muscle resulting in prolonged menstrual flow
Definitive diagnosis: ADENOMYOSIS- Diagnosis is confirmed following histologic examination of a
hysterectomized uteruso Retrospective diagnosis
Pelvic Exam: ADENOMYOSISRarely causes uterine enlargement greater than 14 weeks size
ENDOMETRIOSIS, ADENOMYOSIS, DYSMENORRHEA- Enlargement uterus is soft or squishy to the feel- A sonogram (ultrasound)and laparoscopic evaluation may also be
helpful in making the diagnosis- MRI’s can often identify adenomyosis- Examination of the surgical specimen under a microscope is the
only method to make an absolute diagnosis of adenomyosis
Management: ADENOMYOSISThe treatment options for adenomyosis are similar to those of endometriosis:
1. Observation – If the symptoms are not severe2. Medical treatment:
- Birth control pills- GnRH agonists – will temporarily alleviate the symptoms and
reduce the size of the adenomyosiso Will not eliminate the adenomyosis nor prevent continued
growth once the GnRH is discontinued
Conservative surgical treatment- Indications:o A woman who is trying to get pregnanto A single well defined adenomyosiso A woman who does not want a hysterectomy and does not
mind undergoing repeated surgeries- Removal of the adenomyosis and preserve the uterus –
impossible- Adenomyomectomyo Removal of the adenomyosis with recontraction of the uterus
will reduced the amount of adenomyosis present
DysmenorrheaDefinition:
- A severe, painful cramping sensation in the lower abdomen often accompanied by other biologic symptoms, all occurring just before or during the menses such as:o Sweating, tachycardia, headaches, nausea, vomiting, diarrhea,
and tremulousnessPrimary dysmenorrhea
The term refers to pain with no obvious pathologic pelvic disease Primary dysmenorrheal almost always first occurs in women
younger than 20 Indeed, the patient will report pain as soon as she establishes
ovulatory cycles These patients are suffering from the effects of endogenous
prostaglandins
Secondary dysmenorrhea Is associated with pelvic conditions or pathology that causes
pelvic pain in conjunction with the menses May occur in women younger than 20, but it is most often seen in
women older than 20
Incidence of Dysmenorrhea Wide range (16-90%) average 75% Mildo No systemic symptoms, medication rarely required, work rarely
affected Moderateo Few systemic symptoms, medication required, work
moderately affected Severeo Multiple symptoms, poor medication response, work inhibited
Less likely to have dysmenorrhea are: Women who had vaginally delivered a childo Pregnancy itself without actual birth did not seem to alleviate
dysmenorrhea As women who had ectopic pregnancies or spontaneous or
voluntary terminations of pregnancy were not relieved of their symptoms
Smokers were less likely to have dymenorrhea Users of oral contraceptive (OC)
Family historyo Increased among mothers and sisters of women with
dysmenorrhea
Pathogenesis of Primary dysmenorrhea Associated between elevated prostaglandin F2a (PG F2a) levels in
the secretory endometrium and the symptoms of dysmenorrhea, including:o Uterine hypercontractilityo Complaints of severe crampingo Other prostaglandin – induced symptoms
Arachidonic acid:o Increased amounts in the uterus during ovulatory cycleso The precursor to prostaglandin productiono Converted to PG F2a, PGE2, and leukotrienes
Which are involved in increasing myometrial contractions During menses contractions decrease uterine blood flow and
cause ischemia and sensitization of pain fiberso Ultrasound & MRI have correlated dysmenorrheal with
myometrial changes and decreased blood flowo PG F2a and PGE2 affect other organs such as the bowel and
result in nausea, vomiting and diarrhea During menses these contractions decrease uterine blood flow
and cause ischemia and sensitization of pain fibers Mechanisms contributing to generation of pain in primary
dysmenorrheal
Diagnosis of primary dysmenorrheaThe diagnosis is made by the history & PE
Midline, cramping lower abdominal paino Begins with the onset of menstruation
May be severe pain and also involve the low back and thighs Gradually resolves over 12 to 72 hours Pain does not occur at times other than menses
Physical exam With primary dysmenorrheal have a normal pelvic exam
Treatment of primary dysmenorrheal Nonsteroidal anti-inflammatory drugs (NSAIDs)o Prostaglandin synthetase inhibitors (PGSI)o Demonstrated to alleviate these symptoms of primary
dysmenorrhealo These substances are nonsteroidal and anti- inflammatory
Two chemical groups of PG inhibitors: Arylcarboxylic acids:o Acetylsalicylic acid (aspirin) o Fenamates (mefenamic acid)
Arylalkanoic acids:o Arylpropinoic acids (ibuprofen, naproxen)o Indoleacetic acids (indomethacin)
Treatment of primary dysmenorrheal Cyclooxygenase (COX-2) inhibitorso Ex. Celecoxibo COX-2 expression in the uterine glandular epithelium was
maximal during menstruation Suggesting a possible association with the cause The increased expression of COX-2 was eliminated with
continuous use of OCs which are also an effective treatment The specific effect of COX-2 inhibitors on the uterine musculature
is:o Reduction of the contractility as measured by reduction of
intrauterine pressure
Side effects of NSAIDs & COX-2 inhibitors Minimal NSAIDs –associated side effects involving theo Central nervous system (CNS)o Gastrointestinal tracto Allergy to ASA & NSAIDs
COX-2 inhibitors
ENDOMETRIOSIS, ADENOMYOSIS, DYSMENORRHEAo Serious adverse cardiovascular events
Other treatment modalities Oral contraceptives o OCs will relieve the symptoms of primary dysmenorrheal in
about 90% of patientso OCs suppress ovulation and endometrial proliferationo OCs progestin component blocks the production of
prostaglandin formationOther therapy
Progestaserto Reduce menstrual pain in women
Microwave endometrial ablation with transcervical resection of the endometrium for menorrhagia o Showed both techniques reduced menstrual pain
Transcutaneous electrical nerve stimulation (TENS)o More effective than placebo in relieving dysmenorrheal
although this was not as effective as analgesicso Relieved menstrual pain without reducing intrauterine pressure
Presacral neurectomyo Surgical managemento Last resort in the management if all treatment modalities fail
Secondary Dysmenorrhea Pelvic disease should be considered in case that do not respond to
NSAIDs and OCs for presumed primary dysmenorrheal Group of pelvic problems that includeo Cervical stenosiso Ectopic endometrial tissueo Pelvic inflammationo Pelvic congestion o Conditioned behavior
Cervical stenosis Severe narrowing of the cervical canalo At the level of the internal oso Impede menstrual flow causing an increase in intrauterine
pressure at the time of menses Retrograde menstrual flow through the fallopian tubes into the
peritoneal cavity may take place Thus severe cervical stenosis may eventually be associated with
pelvic d as well
Etiology: cervical stenosis Congenital Secondary to cervical injuryo Electrocautery, cryocautery or operative trauma(l.e. conization)o From an inflammatory process caused by infectiono The application of caustic substances
Hypoestrogenismo After any of these conditions the cervical canal may narrow
because of contraction of scar tissueHistory
Cervical stenosis should be consideredo History of scant menstrual flow o If severe cramping continues throughout the menstrual periodo A hematometria or pyometria may occur
DiagnosisPelvic exam
- Scarring of the external os- Impossible to pass a pap smear brush or uterine sound through
the internal os during the proliferative stage of the menstrual cycle
Diagnosis is generally documented- By the inability to pass a thin probe of a few millimeter diameter
through the internal os- By hysterosalpingogram ( thin stringy appearing canal if
hysteroscopy end )- D&C – difficult to pass a thin probe into the internal os
Treatment: cervical stenosis Dilating the cervix by D&C
- Progressive dilator- Progressive use of Laminaria japonica tent
: Unfortunately, cervical stenosis often recurs after therapy, necessitating repeat procedures
Pregnancy and vaginal delivery often afford a more lasting cure
Pelvic inflammation Gonorrhea, Chlamydia, or other infections
- May cause pelvic inflammation or pelvic abscess.- Healing may be associated with pelvic adhesions and tubal
damage that may cause pelvic pain
Pelvic inflammatory disease (PID) can lead to chronic pelvic pain in up to 30% of women.
- May be aggravated at menses, causing dysmenorrheal.
Other Pelvic InflammationInfections secondary
- Appendicitis- IUD use, may also create a similar response.o The pain may be secondary to the congestion and edema that
occur normally at menses, which may subsequently be aggravated by the healed inflammatory areas and adhesions.
pelvic pain – usually burning or throbbing in nature, worse at night and worse after standing.
Pelvic congestion syndrome- results from engorgement of pelvic vasculature.
Physical examination of the vagina and cervix usually reveals vasocongestion with evidence of some uterine enlargement and tenderness..
Diagnosis: Pelvic Congestion syndromeMade by:
- Observation of the features noted - Laparoscopyo Rules out other cause of pelvic paino Demonstrates congestion of the uterus and engorgement or
variscosities of the broad ligament and pelvic side wall veins.
Diagnostic Laparoscopy: Pelvic Congestion syndrome- Observe the broad ligament vasculature as the pressure of the
carbon dioxide or nitrous oxide is releasedo At full pressure during the procedure these vessel may be
obliterated but will reappear as pressure is reduced
Treatment: Pelvic Congestion syndrome- No standard therapeutic approach is availableo Ovarian hormone suppressiono Local sclerotherapy (for vulvar varices)o Embolization of the hypogastric veino Resection of the gonadal veino Hysterectomy
Other causes – secondary dysmenorrheal- Leiomyomas or polyps at the junction of the internal os and lower
uterine segmento May produce a valve-like effect at the os at the time of menseso Become engorged or edematous at the time of menses,
accentuating the problemOther causes
- Diagnosis of leiomyomas or polyps by:o Historyo Hysterosalpingographyo Hysteroscopyo D&C
- Therapy consists of:o Excising the pathologic tissueo Myomectomy or hysterectomy may be necessary
ENDOMETRIOSIS, ADENOMYOSIS, DYSMENORRHEAPremenstrual syndrome (PMS)
- A group of mild to moderate symptoms, both physical and behavioralo Occur in the second half of the menstrual cycle ando May interfere with work and person relationships.o Followed by a period entirely free of symptoms.
Premenstrual Dysphoric Disorder (PMDD)- Represents a more severe disorder with marked behavioral
emotional symptoms.- PMS differs from PMDD in severity of symptoms, and women with
PMDD must have one sever e affective symptoms.Symptoms:
o Markedly depressed mood hopelessnesso Anxiety or tensiono Affective lability, oro Persistent angero Multiple physical symptoms may also be present.
- PMDD also differs from PMS as there is substantial impairment in personal functioning.
- PMS and PMDD are similar in that the symptoms manifest in the luteal phase of the menstrual cycle and resolve during menses.
Symptoms- Somatic symptomso Related to abdominal bloating, breast tenderness, and various
pain constellations such as headache.- Psychological symptoms varyo From fatigue, irritability, and tension to anxiety, labile mood
and depression- Consistency of symptoms was found over two consecutive cycles,
especially for emotional symptoms.
PMS/PMDD etiology- Ovulationo Seems to cause alterations in neurohormones and
neurotransmitters that lead to reduction of serotonergic function during the luteal phase.
- The most effective evidence-based treatment for moderate to severe PMS and PMDD symptoms are SSRIs and agents that block ovulation.
Drug Management PMS/PMDD- Therapy with psychoactive drugso The selective Serotonin Reuptake Inhibitors (SSRIs)o Extremely effective for treating PMS o First-line treatment for PMDD.
