For the symptomaticfibroid, hysterectomyoffers a definitive solution.
However, it is not thepreferred solution for

INTRODUCTION
Uterine leiomyomas are themost common gynaecological
tumours andare present in 30% of
women of reproductive age.
8/8/2019 Lei Om Yo Mas

Treatment of women withuterine leiomyomas must be
individualized, based on:1. Symptoms,2. Size and
3. Rate of growth of the uterus,and4. The womans desire for fertility.

The majority of uterineleiomyomas are asymptomaticand will not require therapy.
However,75% of
hysterectomies are performedfor menorrhagia with fibroids.

CLINICAL FEATURES
The vast majority of leiomyomasare asymptomatic.
The most common symptom of
uterine leiomyoma isabnormal uterine bleeding.
In published series ofmyomectomies , 30% of womensuffered from menorrhagia.
8/8/2019 Lei Om Yo Mas
14/158
The mechanism of fibroid-associatedmenorrhagia is unknown.
1. Vascular defects,
2. Submucous tumours, and
3. Impaired endometrial hemostasis have been offered as possible
explanations.
CLINICAL FEATURES
8/8/2019 Lei Om Yo Mas
15/158
Pelvic pain is rare with fibroids andit usually signifies degeneration,torsion, or, possibly, associatedadenomyosis.
Pelvic pressure,
bowel dysfunction, and
bladder symptoms such as urinaryfrequency and urgency
may be present.
CLINICAL FEATURES
8/8/2019 Lei Om Yo Mas
16/158
Urinary symptoms should
be investigated prior tosurgical management offibroids to exclude other
possible causes.
CLINICAL FEATURES
8/8/2019 Lei Om Yo Mas

In the postmenopausal
woman presenting withpain and fibroids,
leiomyosarcoma shouldbe considered.

Clinical examination is
accurate with a uterine size of12 weeks(correlating with a uterine
weight of approximately300 g) or larger.
8/8/2019 Lei Om Yo Mas

Ultrasonography
is helpful to assess theadnexa if these cannot
be palpated separatelywith confidence.

Although reliable inmeasuring growth,routine ultrasound
is not recommended
as it rarely affectsclinical management.
EVALUATION
8/8/2019 Lei Om Yo Mas

In women with large fibroids,diagnostic imaging will
occasionally demonstratehydronephrosis, the clinicalsignificance of which is unknown.
Complete ureteric obstructionis extremely rare.
EVALUATION
8/8/2019 Lei Om Yo Mas

In women who present with
abnormal uterine bleeding,it is important to excludeunderlying endometrial
pathology.

MEDICALMANAGEMENT
Treatment should be
tailored to the needs of thewoman presenting with
uterine fibroids and gearedto alleviating the symptoms.
8/8/2019 Lei Om Yo Mas

There is no evidence that
low-dose oral contraceptivescause benign fibroids togrow, thus uterine fibroids
are not a contraindicationto their use.

Fibroids may be expected to shrinkby up to 50% of their initial volumewithin 3 months of therapy.
GnRH agonist treatment should berestricted to a 3- to 6-monthinterval, following which regrowthof fibroids usually occurs within12 weeks.
(GnRH) agonists
8/8/2019 Lei Om Yo Mas

GnRH agonists are
indicated preoperativelyto shrink fibroids and to
reduce menstrual relatedanemia.

Tranexamic acid may reducemenorrhagia associated withfibroids.
Progestins may be associatedwith fibroid growth.

Danazol has been associated witha reduction in volume of the
fibroid in the order of20% to25%.
Although the long-term responseto danazol is poor, it may offer anadvantage in reducing
menorrhagia.

The only indications forhysterectomy in a woman with
completely asymptomatic fibroidsare:
1. Rapidly enlarging fibroids or,
2. When enlarging fibroids raiseconcerns ofleiomyosarcoma(after menopause).

LAPAROSCOPICMYOMECTOMY
For several pelvic disorders,gynaecologists have
resorted to minimal accesssurgery in an effort to:
1. Reduce hospital stay and2. Improve recovery time.
8/8/2019 Lei Om Yo Mas
43/158
Myomas may be removed bya laparoscopic approach.
The challenges of this surgeryrest with the surgeons ability to
1. Remove the mass through a
small abdominal incision and to2. Reconstruct the uterus.

8/8/2019 Lei Om Yo Mas
44/158
A few case series have beenpublished including more than500 women with fibroids ranging
from 1 cm to 17 cm.When compared to a laparotomy,
the laparoscopic approach appears totake longer but is associated with aquicker recovery.

Concerns have been raisedregarding the ability to

In one case-control series there werefewer postoperative adhesions in

In a review of availablerecommendations, most suggest
a laparotomy for:1. Fibroids exceeding 5 cm to 8 cm,
2. Multiple myomas, or3. When deep intramural
leiomyomas are present.

Laparoscopic-assisted myomectomypresents an opportunity to enucleate themyoma partially by laparoscopy, deliver
the tumour through a small abdominalincision, then close the uterine defect
through this laparotomy.

Pretreatment with a GnRH analogue for3 months prior to myomectomy :
1. May increase the preoperative

FIBROIDS AND INFERTILITY
The impact of fibroids onfertility is controversial.

FIBROIDS AND INFERTILITY
FIBROIDS AND INFERTILITY
8/8/2019 Lei Om Yo Mas
109/158
Various theories have been advanced toexplain the potential subfertility effect of
fibroids:1. Dysfunctional uterine contractility,
2. Focal endometrial vascular disturbance,3. Endometrial inflammation,4. Secretion of vasoactive substances, or5. Enhanced endometrial androgen environment.
The published evidence suggeststhat submucous fibroids are more
likely to cause subfertility.
FIBROIDS AND INFERTILITY
8/8/2019 Lei Om Yo Mas
110/158
Fibroids larger than 5 cm, and thoseclose to the cervix or tubal ostia, arealso thought to be more problematic.
In women undergoing IVF cycles ,submucous or intramural myomas,which distort the uterine cavity, havea negative impacton implantationand pregnancy rates.
FIBROIDS AND PREGNANCY
