Leio-myoma Uterus

Fibro-myoma
❑Synonyms:Myoma,Leiomyoma,Fibromyoma
❑It is most common benign neoplasm in the female.
❑Common benign solid tumorin females
❑Average age is 35-45 years.
❑Incidence : 20 to 40% of reproductiveage women.

Fibromyoma
Etiology:
It arises from smooth muscle cell ofmyometrium.
❑Exact etiology notknown.
❑Monoclonal origin ( arising from singlecell)
❑Various growth factors like TGFβ , EGF, IGF-1, IGF-2, BFGF
(Oestrogen dependent Tumor)

Fibromyoma-Etiology
Multiple chromosomal abnormalities-detected in 50% of fibroid patients
❑Translocation between Chromo. 12 &14,
❑Trisomy12,
❑Rearrangement of short arm of Chromo6
❑Rearrangement of long arm of Ch.10,
❑Deletion of Ch.3 orCh.7or long arm of Y chromosome.

Fibromyoma-Etiology
Increase state of Estrogen in the body-
Hyper-oestrogenismhas been proved for causing myoma
❑Not detected before puberty
❑Theyregresses after menopause
❑Never arise in menopause.
❑May increase duringpregnancy
❑Estrogen receptors are in higherconcentration
❑Commonin Obesity, PCOS, DUB,Endometrialcarcinoma
❑Less in smokers
❑Regresses with OCPs.

❑LAVH,TLH

Hystrectomy—
Routes=abdominal, vaginal (open/laproscopic)
Sub-total hysterectomy= uterus minus cervix is removed
Total hysterectomy= uterus + cervix
Total abdominal hysterectomy with Bilateral salpino-oophorectomy=Pan-
hysterectomy
Werthiem’shysterectomy-
1. Modified Radical = TAH+ B/L S.O + Medial part of parametrium+ Upper vaginal
cuff+ pelvic lymphadenectomy
2. Radical=TAH+ B/L S.O + parametrium up to lateral pelvic wall + Upper vaginal
cuff+ pelvic lymphadenectomy

SurgicalManagement
Myomectomy is done in following:-
Indications for surgery→
Infertility caused by cornualfibroidblocking
tube.
Habitualabortionduetosubmucousfibroid.
Pedunculatedfibroid likely to undergotorsion.
Fibroid > 12weeks.
Broad ligament fibroid pressing onureter.
Fibroidpressingoverbladdercausingretentionofurine/
infection.
Rapidly growing uterine fibroid in postmenopausal
women.

Myomectomy-Routes
❑Abdominal
❑Vaginal
❑Method
❑Laproscopic
❑Hysteroscopic
❑Open
Myomectomy is enucleationof myoma
from the uterus leaving behind
potentially funtionaluterus capable of
future reproduction.

Indications of Myomectomy
❑Persistent uterine bleeding despite medical treatment.
❑Excessive pain or pressure symptoms
❑Size> 12 weeks, woman desriousof having pregnancy
❑Unexplained infertility with distortion of uterine cavity.
❑Recurrent pregnancy loss.
❑Rapidly growing fibro-myoma during follow up
❑Pedunculated Sub-serosal fibromyoma

Contra-indications of Myomectomy
❑Infected fibroid
❑Growth of fibroid after menopause
❑Suspected malignant change
❑Parous woman where hysterectomy is a safe choice.
❑Pelvic or endometrial Tuberculosis
❑During prernancy
❑During c. section.

Time of myomectomy
❑Immediate Post-menstrual period to reduce blood loss
❑Should not be performed during pregnancy
❑Should not be performed during c.section.
❑Results
❑Pregnancy rate after myomectomy=40-60%
❑Recurrence rate=30-50%
❑20-25% ultimately come for Hystrectomyin later life.

Pre-operative management Protocol
❑Anemiashould be corrected.
❑(parentralirontherapyalong withfolicacid,vitaminC,proteinsuplementation.)
❑Arrange for Blood transfusion.( atleast2 units) (Auto transfusion / donor blood
transfusion)
❑Control of bleeding→GnRHagonisttherapy( atleastone month prior to surgery)
❑Control of associated medical problems like hypertension, CHF, Asthma, UTI,
kidney or liverillness.
❑D& C must prior to myomectomy
❑Patient should be investigated prior to myomectomy for complete infertility
investigations including Husband’ seminologyto rule out other causes of infertility.
❑Written consent for hysterectomy has to be taken prior to myomectomy because of
risk of heavy bleeding during surgery.

Abdominalmyomectomy
Pre-requisites
❑Other factors for infertility should be ruledout
❑Take written consentwith risk ofhysterectomy
❑Cross matched Blood should be ready.
❑Pap smear & endometrial sampling to rule out malignancy.
❑Medical or mechanical means to control blood loss -available
❑Bonney’sMyomectomy clamp, rubber tourniquet, manual ( finger
compression) pressure at isthmic region
❑or use of vasopressin 10 –20 units diluted in 100ml saline infiltrated
before putting the incision.

•For submucous myoma causing infertility, Recurrent pregnancy
loss, AUB orpain
•Criteria:-< 5 cm insize
< 50 % intramuralcomponent
< 12 cm

uterinesize

Laparoscopicmyomectomy
❑In 3 phases
❑excision of myoma, repair ofmyometrium &extraction
❑Suitable for subserous & intramural fibroids upto 10 cm size
❑Complications are those of operative laparoscopy + myomectomy

Myomectomy Instruments

Abdominalmyomectomy
❑Minimum incisions are kept –preferably single midline
vertical, lower, anterior wall.
❑Removal of as many fibroids as possible through one incision
& secondary tunnellingincisions.
❑Meticulous closure of all deadspace.
❑Properhaemostasis
❑Multiple small fibroids can be removed enbloc by wedge
resection.
❑Measures for adhesion prevention should betaken.

OpenMyomectomy

Vaginalmyomectomy
❑Submucous pedunculated or small sessile cervical
fibroids are removedvaginally.
❑Ligation of pedicle ifaccessible
❑Twisting off the fibroids if pedicle not accessible in case
of small & medium sizefibroids
❑To gain access to pedicle of higher & big fibroid incision
on the cervix can bemade.

Important considerations-Myomectomy
❑It should be done to preserve the reproductive function.
❑It is more risky operation than hysterectomy when fibroids are too many or too big.
❑Risk of recurrence is about 30-50%
❑Risk of persistence of menorrhagia is 1-5%
❑Risk of re-laparotomy is about 20-25%
❑Pregnancy rate after myomectomy is 40-60%
❑Pregnancy after myomectomy should be done in hospital to avoid chances of scar rupture during labour.
❑Complications-hemorrhage during operation, within 24 hrs( reactionary),>24hrs-secondary Hge
❑Trauma to bladder, ureter, Gut, Rectum
❑Infection-wound sepsis,
❑Complications of anaesthesiainclude aspiration Pneumonia, Paralytic ileus etc.

Radical SurgicalManagement
❑Abdominal or Vaginal hysterectomy
❑Vaginal hystrectomyis favoured in following;
❑If Uterus< 14wks
❑With no associated pathology like endometriosis , PID, adhesions
❑Uterus mobile & adequatelateralspaceinpelvis
❑Experienced vaginal surgeon

Uterine arteryembolization

Uterine arteryembolization
❑By interventionalradiologist
❑Catheter is passed retrograde thro. Right femoral artery to bifurcation of
aorta & then negotiated down to opposite uterine arteryfirst.
❑Polyvinyl alcohol ( PVA ) particles ( 500-700 um) or gelfoamareused
forembolization.
❑60 –65 % reduction in size offibroid
❑80 –90 % have improvements in menorrhagia & pressuresymptoms

.

Uterine artery
embolization

AdvantagesOf UAE
❑No majorsurgery.
❑No intra-operativebleeding.
❑Short hospitalstay.
❑No abdominaladhesions.
❑75-80% women suffering from menorrhagia aresatisfied.

Uterine arteryembolization
•High vascularity & solitary fibroid are associated with greater chance of
long termsuccess.
•Pregnancy, active infection & suspicion of malignancy are absolute C I.
•Desire for fertility is also acontraindication
•The risk of ovarian failure must becounselled
•Post embolization syndrome ( fever, vomiting, pain) canoccur

Latest SurgicalManagement
❑Laparoscopic myolysis:
❑By ND-YAG laser or long bipolar needle electrode through laparoscope,
blood supply of myoma iscoagulated.
❑Without blood supply, myomaatrophies.
❑Applicable to 3 -10 cm size & myomas < 4 in number
❑Cryomyolysisis underinvestigation

Leio-myosarcoma
❑Incidence=0.2-0.5%
❑Age= usually Post-menopausal.
❑When fibroid starts growing rapidly with acute pain in Post-menopausal woman
with tenderness. Always suspect leio-myosarcoma.
❑Most common in sub-mucous, followed by intra-mural fibroid.
