Q

What is a Uterus unicornis?

Q

What is a Uterus didelphys?

A

the uterus is present as a paired organ as the embryogenetic fusion of the mullerian ducts failed to occur. As a result there is a double uterus with two separate cervices, and often a double vagina as well. Each uterus has a single horn linked to the ipsilateral fallopian tube that faces its ovary

Leiomyoscarcoma: Cancer

93

94
Q

95
Q

Adenomyoma

A

Adenomyoma

96
Q

What is a Adenomyoma?

A

Uterrine thickening due to the endometrial tissue moving into the outer muscular walls of the uterus – cells grow directly into the uterine walls

97
Q

What happened to Adenomyoma during menstration?

A

Since it is made out of endometrial tissue, the Adenomyoma will bleed just like the endometrial tissue does. This bleeding will be directly into the muscle and cause pain

98
Q

As the Adenomyoma bleeds into the muscle and the blood begins to accumulate what happened?

A

The surrounding muscles will swell and forms fibrous tissue in response to the irritation.

99
Q

How do mild to servere Adenomyoma presen like?

A

May be asymptomatic

100
Q

More severe forms:

A

may lead to heavy bleeding and severe cramps during menstrual period

101
Q

Adenomyoma are found in what percent of women?

A

10%

102
Q

How do you diagnose Adenomyoma?

A

Suspected in uterine enlargment and tenderness to palpation, may be suggested by the apperance of the uterus on sonoram (MRI is better at detecting adenomyosis, but the test is $$), Also Surgical excision: onced removed the tissue can be examined under the microscope and the uterine lining cells can be seen within the muscle wall.

103
Q

How do you treat Adenomyomas?

A

Lupron or synarel: can cause cessation of periods and associated menstral crampine, lead to shrinkage of the swelling associated with adenomyomas. The only true cure is surgery (small sxr or hysterectomy depending on the size)

104
Q

What is Lupron or Synarel?

A

Modifications of the natural GnRH.

105
Q

Endometriosis

A

Endometriosis

106
Q

What is Endometriosis?

A

Presence of abnormal growth of tissue, histologically resembling the endometrium present in locations other than the uterine lining

107
Q

Who is common to have Endometriosis?

A

6-10% of females, almost exclusive to women of reproductive age, most common in nulliparous women

108
Q

What is the Etiology of Endometriosis?

A

Pathogenesis and natural cause is not fully understood, may be from retrograde menstruation( most accepted cause) can also be from vascular and lumphatic dissemination, coelomic metaplasia of multipotential cells in the peritoneal cavity may develop into functional endometrium.

109
Q

What will decrease the risk for Endometriosis?

A

Multiple births, extended intervals of lactation and late menarche (after 14)

110
Q

What will increase the risk of Endometriosis?

A

Nulliparity, early menarche/late menopause, short menstrual cycles, prolonged menses, mullerian anomalies, associated with taller and thinner habitus and lower body mass index

111
Q

What are the clinical manifestations of Endometriosis?

A

Variable and unpredictable in presentation and course, severity of pain may be inversely related to anatomic extent of the disease. Symptoms may include dysmenorrheal, chronic pelvic pain, dyspareunia and possibly asymptomatic.

112
Q

What will the pelvic findings in a patient with Endometriosis?

A

Tender nodules in cul-de-sac or retrovaginal septum

Urerine retroversion with decreased uterine mobility

Cervical motion tenderness

Adnexal mass or tenderness

Most will have normal pelvic examinations

113
Q

How do you diagnose Endometriosis?

A

Imaging: limited value : useful only in the presence of pelvic or adenxal mass, use transvaginal ultrasound 9used to detect deeply penetrating endometriosis of rectum or rectovaginal septum) MRI (reserved for equivocal cases of retrovaginal or bladder endometriosis

Definite diagnosis: Histology of lesions excised by surgical interventions

114
Q

What is the treatment of Endometriosis?

A

NSAIDs- just for pain relief

Hormonal Treatment- effective in alleviation of pain- designed to inhibit ovulation over 4-9 mo and lower hormone levels.

Surgery

115
Q

What hormone treatment is available for Endometriosis?

A

OC, contraceptive patch or vaginal rings- prolongs suppression of ovulation inhibiting further simulation of residual endometriosis.

Progestins- specifically norethindrone acetate and subcutaneous DMPA) approved by the FDA for treatment of Endometriosis.

GnRH agonists- Nafarelin nasal spray or long acting injectable leurolide acetate- suppresses ovulation, its highly effetive in reducing pain associated with endometriosis. Not superiour to other methods as first line therapy, side effects include vasomotor symptoms and bone demineralization

Danazol- androgenic drug- use it for 4-6 mo in lowest dose necessary to suppress menstruation, s/e of androgenic side effect

Intrauterine progestin with levonorgesttrel intrauterine system

Aromatase Inhibitors- Anastrozole or Letrozole- Promising but insufficient data

116
Q

What is the surgical treatment of Endometriosis:

A

Effective in both reducing pain and in promoting fertility.
Laproscopic ablation of endometrial implants along with uterine nerve

Ablation of implands (+/- removal of ovarian endometriomas) enhance fertility.

Total abdominal hysterectomy and bilateral salpingoopherectomy (TAH-BSO)- definitate treatment, will need hormone replacement.

117
Q

What is the prognosis of endometriosis?

A

Reproductive function in early or moderately advanced Endometriosis appears to be good with conventional therapy.

A

Hyperplastic overgrowth of the endometrial glands and troma that foams a projection (sessile or pedunculated) from the surface of the endometrium.

120
Q

Where do the majority of Endometrial Polyps?

A

Most originate from endocervix

121
Q
