Study Notes
Definition
- Endometriosis is a condition where endometrial tissue (typically found in the lining of the uterus) grows outside of the uterus.
- This condition is benign, meaning it is not cancerous.
Occurrence
- Endometriosis affects approximately one-third or more women experiencing chronic pelvic pain.
- Most commonly diagnosed in women in their 30s, who have not given birth, and are infertile.
- However, it can affect women throughout their reproductive years.
Theories of Pathogenesis
- Retrograde menstruation is a leading theory for endometriosis.
- During menstruation, endometrial fragments are transported through the fallopian tubes and implant at various locations within the abdomen.
Sites of Occurrence
- Ovaries
- Cul-de-sac
- Uterosacral ligaments
- Broad ligament
- Fallopian tubes
- Round ligaments
- Vagina
- Rectosigmoid and bowel, appendix
- Urinary bladder and ureters
Symptoms
- Dysmenorrhea (painful menstruation)
- Dyspareunia (painful intercourse)
- Dyschezia (pain with bowel movements)
- Cyclic and non-cyclic pelvic pain
- Infertility
- Secondary dysmenorrhea
- Premenstrual and postmenstrual spotting (approximately 20% of cases)
Physical Exam
- No specific sign can definitively confirm endometriosis.
- Common findings include:
- Recto-vaginal exam findings
- Cul-de-sac nodularity and tenderness
- Uterosacral nodularity
- Tender, fixed adnexal mass
- Uterus fixed and retroverted
Diagnosis
- Ruling out other causes is crucial.
- Ultrasound: An adnexal mass with complex echogenicity and internal echoes consistent with blood can be observed.
- Definitive Diagnosis: Visual examination with laparotomy or laparoscopy, and histological confirmation of endometrial tissue.
- Other tests, including Ca125, are not reliable indicators of endometriosis.
Pathology
- "Chocolate cysts" in the ovaries are a common characteristic of endometriosis.
- These cysts are filled with old endometrial shedding and blood, giving them a thick, tarry consistency.
- Ruptured cysts can cause chemical peritonitis.
- Adhesions are a common consequence of endometriosis.
Staging
- A staging system exists for endometriosis, but there is no clear correlation between the stage and the severity or frequency of pain symptoms.
Management Considerations
- Severity of Symptoms
- Extent of the disease
- Desire for future fertility
- Age of the patient
- Threat to the Gastrointestinal or Urinary tract
Treatment Options
- Excision or ablation surgery
- Pelvic physical therapy
- Medications for pain, birth control, and GnRH agonists
- Treatments for co-occurring conditions
- Self-care
Medical Management
- First-line treatment (minimum of three to six months):
- Oral contraceptive pills (OCP’s), cyclic or continuous
- Progestins
- Aromatase inhibitors
- Referral for laparoscopy for diagnosis and treatment if these fail.
- Second-line medical treatments (usually after laparoscopy):
- Mirena IUD (levonorgestrel)
- GnRH agonists (Lupron)
- GnRH agonists should not be administered without prior diagnostic laparoscopy.
- Pain relief alone does not confirm an endometriosis diagnosis.
Surgical Management
- Fertility-preserving:
- Laparoscopy (or rarely, laparotomy) with ablation or excision of endometrial implants and adhesions.
- Endometriomas larger than 3 centimeters in diameter should be surgically removed.
- Most definitive:
- Hysterectomy (often laparoscopic) with ablation or excision of all endometrial implants and adhesions.
- Removal of ovaries was previously a traditional option, but recent studies suggest that preserving ovaries is reasonable in many cases.
- Recurrence is always a risk.
Related Disorder: Adenomyosis
- Ectopic endometrial tissue within the myometrium.
- Typically affects parous women between 35 and 50 years old.
- Symptoms:
- Often asymptomatic
- Secondary dysmenorrhea, abdominal pressure, bloating
- Menorrhagia
- Dyspareunia, sometimes chronic pelvic pain
- Examination findings:
- Diffusely enlarged, globular, tender uterus
- Diagnosis:
- Strong clinical suspicion based on history findings and exam findings
- Characteristic findings on ultrasound and MRI
- Definitive diagnosis confirmed through pathology report.
Bottom Line Concepts
- Endometriosis is most prevalent among women in their reproductive years who are subfertile.
- The exact cause of endometriosis remains uncertain and is likely attributed to a combination of factors.
- Dysmenorrhea, dyspareunia, and dyschezia are the classic symptoms associated with endometriosis.
- The stage of endometriosis does not reliably correlate with the frequency or severity of pain.
- Treatment approaches vary and should consider the severity of symptoms, disease extent, future fertility aspirations, and patient age.
- Endometriosis can reoccur throughout a woman's life.
- Minimizing menstrual flow and suppressing ovarian cycling can reduce the risk and symptoms of endometriosis.
Endometriosis Definition
- Endometrial glands and stroma are found outside the uterine cavity and walls.
- This condition is benign.
Endometriosis Occurrence
- Affects more than one third of women with chronic pelvic pain.
- Most common in women in their 30s.
- Often presents in nulliparous women (women who have never given birth).
- Commonly associated with infertility.
- Can present throughout the reproductive years.
Pathogenesis of Endometriosis
- Endometrial fragments transported through fallopian tubes at time of menstruation and implant at intraabdominal sites.
Endometriosis Sites of Occurrence
- Ovary (most common)
- Cul-de-sac
- Uterosacral ligaments
- Broad ligament
- Fallopian tubes
- Round ligaments
- Vagina
- Rectosigmoid and bowel, appendix
- Urinary bladder and ureters
Endometriosis Symptoms
- Classic Triad: dysmenorrhea (painful menstruation), dyspareunia (painful intercourse), and dyschezia (painful defecation).
- Pain (cyclic and non-cyclic).
- Infertility.
- Secondary dysmenorrhea.
- Premenstrual and postmenstrual spotting.
Physical Exam
- No pathognomonic finding (no “telltale sign”).
-
Potential findings:
- Recto-vaginal exam findings.
- Cul-de-sac nodularity and tenderness.
- Uterosacral nodularity.
- Tender, fixed adnexal mass.
- Uterus fixed and retroverted.
Diagnosis
- Rule out other causes.
- Ultrasound – adnexal mass of complex echogenicity, internal echoes consistent with blood.
-
Definitive diagnosis:
- Direct visualization (via laparotomy or laparoscopy).
- Histologic and gross findings consistent with endometrial tissue.
- Other tests.
- Ca125 - not specific nor sensitive; not a reliable indicator of endometriosis.
Pathology of Endometriosis
-
“Chocolate cysts” of the Ovary:
- Endometrial cysts filled with old endometrial sheddings and blood.
- Typically very tarry and sticky.
- Can cause chemical peritonitis if ruptured .
- These cysts are characteristic of endometriosis.
- Adhesions.
Staging
- A system of staging exists so that caregivers can communicate with each other re: locations of disease.
- There is no clear relationship between stage and frequency and severity of pain symptoms.
Management
-
Key considerations:
- Severity of the symptoms.
- Extent of the disease.
- Desire for future fertility.
- Age of the patient.
- Threat to GI or urinary tract.
Endometriosis Treatment Options
- Excision or ablation surgery.
- Pelvic physical therapy.
- Medication for pain, birth control and GnRH agonists.
- Treatments for co-occurring conditions.
- Self-care.
Medical Management
-
1st line treatment (adequate trial of 3-6 months).
- OCP’s , cyclic or continuous.
- Progestins (i.e.MPA or DMPA).
- Aromatase Inhibitors.
- If these are failing, strongly consider laparoscopy to both diagnose and treat the disease.
-
2nd line medical treatments (usually tried after diagnosis confirmed by laparoscopy).
- Mirena IUD (levonorgestrel).
- GnRH agonists (Lupron).
- Should not be done without laparoscopy first.
- Relief of pain does not make the diagnosis of endometriosis.
-
GnRH Agonists.
- Monthly or q3 months x 6 months; no more than 2 courses unless patient is on add back therapy.
Surgical Management
-
Fertility preserving:
- Laparoscopy (or rarely, laparotomy) with ablation or excision of endometrial implants and adhesions.
- Endometriomas >3 cm in diameter should be removed surgically.
-
Most definitive:
- Hysterectomy (most often laparoscopic) with ablation or excision of all endometrial implants and adhesions.
- Removal of ovaries has been traditional, but newer studies suggest retention of ovaries is reasonable in many cases.
-
Risk of recurrence:
- Always a risk of recurrence!
Adenomyosis
- This is a related disorder characterized by the presence of ectopic endometrial tissue within the myometrium.
-
Who gets this?
- Usually parous women (women who have given birth).
- Predominantly between the ages of 35-50 years old.
-
Symptoms:
- Often asymptomatic.
- Secondary dysmenorrhea.
- Abdominal pressure.
- Bloating.
- Menorrhagia.
- Dysparenuia, sometimes chronic pelvic pain.
-
Signs on examination:
- Diffusely enlarged, globular, tender uterus.
-
Diagnosis:
- High index of suspicion based on clinical history and exam findings.
- Characteristic findings on ultrasound and MRI.
- Definitive dx = Pathology report.
Bottom Line Concepts
- The typical patient with endometriosis is in her reproductive years and sub-fertile.
- Pathogenesis of endometriosis is not completely understood and is probably a combination of factors.
- The characteristic triad of symptoms associated with endometriosis is dysmenorrhea, dyspareunia, and dyschezia.
- Stage of endometriosis is not clearly associated with the frequency and severity of pain symptoms.
- Appropriate treatment varies widely and should take into consideration severity of symptoms, extent of disease, and desire for future fertility.
- There is a risk of recurrence of endometriosis throughout a woman’s life.
- Minimizing menstrual flow and suppressing ovarian cycling can reduce the risk for/symptoms of endometriosis.
