Uterine fibroid

This document discusses uterine fibroids, including their definition, incidence, risk factors, clinical manifestations, complications, and management. Some key points: - Uterine fibroids are benign muscle tumors that develop in the uterus and are the most common pelvic tumor in women. - They affect 20-25% of women by age 30 and 50% of women by age 50. Symptoms include heavy bleeding, pain, and infertility. - Risk factors include age, ethnicity, family history, and obesity. Fibroids can be intramural, subserous, or submucous depending on their location. - Treatment depends on symptoms and desire for future fertility. It may include medication,

UTERINE FIBROID What is a UTERINE FIBROID? It is a commonest benign solid tumor of the muscular wall of the uterus composed primarily of smooth muscle and fibrous connective tissue. Also called as uterine leiomyoma, myoma or fibromyoma. Although they can grow to huge size their malignant potential is minimal. Incidence: • They are the most common pelvic tumors. • It has been estimated 20% women at the age of 30 years have got fibroid in their uterus, out of them 50% remain asymptomatic. • In Black women the incidence rate is higher that of White women.
ETIOLOGY ⚫ The aetiology still remains unclear. The prevailing hypothesis are – ⚫ Chromosomal abnormality ⚫ Polypeptide growth factors stimulate growth of leiomyoma either directly or via oestrogen. ⚫ Predominantly an oestrogen – dependent tumor ⚫ They are not detectable before puberty ⚫ Progestrone increase mitotic activity & reduce apoptosis in size ⚫ There may be genetic predisposition
RISK FACTORS ⚫Nultiparity and infertility. ⚫Increasing age . ⚫Ethinicity(two fold in african american compared with white women. ⚫Increased BMI. ⚫Family history. ⚫Hyperoestrogenic state
CLASSIFICATION UTERINE FIBROIDS BODY (CORPOREAL) Interstitial (75%) (Intramural) Subserous (15%) Subserous Broad Ligament (Pseudo) Wandering (Parasitic) Submucous (5%) Sessile Pedunculated (Polyp) CERVICAL Anterior Posterior Central Lateral
CLASSIFICATION
TYPES - Body The fibroid are mostly located in the body of the uterus and are usually multiple.
TYPES – Interstitial or intramural • Initially the fibroid are intramural in position but subsequently, some are pushed outwards or inwards. • Eventually, in about 70% they persist in that position.
TYPES – Subperitoneal or subserous • The intramural fibroid is pushed outwards towards the peritoneal cavity. • The fibroid is either partially or completely covered by peritoneum. • PEDUNCULATED SUBSEROUS FIBROID – The fibroid when completely covered by peritoneum. • WANDERING/PARASITIC FIBROID – When the pedicle is torn the fibroid gets its nourishment from omental or mesenteric adhesions. • BROAD LIGAMENT FIBROID/PSEUDO or FALSE FIBROID – Intramural fibroid may be pushed out in between the layers of broad ligament.
TYPES – Submucous • The intramural fibroid when pushed towards the uterine cavity, and is lying underneath the endometrium, it is called as submucous fibroid. • This variety is least common but produces maximum number of symptoms.
TYPES – Cervical • Cervical fibroid is rare. • In the supravaginal part of the cervix, it may be interstitial or sub-peritoneal variety and rarely polypoidal. • Depending on the position it may be – • Anterior • Posterior • Lateral • Central
PATHOLOGY ⚫ Frequently multiple ⚫ May reach 15 cm in size or larger ⚫ Firm ⚫ Spherical or irregularly lobulated ⚫ Have a false capsule ⚫ Can be easily enucleated from surrounding myometrium
MICROSCOPIC STRUCTURE ⚫Consists of smooth muscles and fibrous connective tissue of varying proportion. ⚫Individual cells are spindle shaped uniform ⚫Varying amount of connective tissue are interlaced between muscle fibers ⚫Pseudocapsule of areolar tissue & compressed myometrium ⚫Arteries are less dense than myometrium & do not have a regular pattern of distribution ⚫1-2 major vesseles are found at the base or pedicle
SECONDARY CHANGES
DEGENERATION - Hyaline • Hyaline degeneration is the most common (65%) type of degeneration affecting all sizes of fibroids except the tiny one. • The feel becomes soft elastic in contrast to firm feel of the tumour. • Naked eye examination on the cut surface shows irregular homogenous areas with loss of whorl-like appearance.
DEGENERATION - Cystic • Usually occurs following menopause and is common in interstitial fibroids. • It is formed by liquefaction of the areas with hyaline changes. • The cystic changes of an isolated big fibroid may be confused with an ovarian cyst or pregnancy.
DEGENERATION - Fatty • Usually found at or after menopause. • Fat globules are deposited mainly in the muscle cells.
DEGENERATION - Calcific • Seen in 10% of the cases. • Usually involves the subserous fibroids with small pedicle or myomas of postmenopausal women. • Usually preceded by fatty degeneration. • There is precipitation of calcium carbonate or phosphate within the tumor. • When the whole of the tumor is converted into a calcified mass it is called as ‘WOMB STONE.’
DEGENERATION - Red • Also known as carneous degeneration occurs in a large fibroid mainly during second half of pregnancy and puerperium. • Naked eye appearance of the tumor shows dark areas with cut section revealing raw-beef appearance often containing cystic spaces. • Odor is fishy due to fatty acids and the color is due to presence of haemolysed red cells and haemoglobin. • Microscopically, evidence of necrosis are present.
DEGENERATION - Red
DEGENERATION - Atrophy • Atrophic changes occur following menopause dur to loss of support from oestrogen. • There is reduction in the size of the tumor. • Reduction also occurs following pregnancy enlargement.
DEGENERATION - Necrosis • Circulatory inadequacy may lead to central necrosis of the tumor. • This is present in submucous polyp or pedunculated subserous fibroid.
DEGENERATION - Infection • The infection gains access to the tumour through the thinned and sloughed surface epithelium of the submucous fibroid. • This usually happens following delivery or abortion. • Intramural fibroid may also be infected following delivery.
DEGENERATION – Vascular changes • Dilatation of the vessels or dilatation of the lymphatic channels inside the myoma may occur. • The cause is unknown.
CHANGES IN PELVIC ORGANS • UTERUS – • Shape – distorted • Myohyperplasia is a constant finding • Endometrium normal • Anovulation • Dilatation and congestion of myometrial and endometrial venous plexuses. • Uterine cavity may be elongated and distorted in intramural and submucous varieties. OVARIES – • Enlarged, congested and studded with multiple cysts.
CHANGES IN PELVIC ORGANS • URETER – • Displacemment of the anatomy of the ureter in broad ligament fibroid. • ENDOMETRIOSIS – • Increased association of pelvic endometriosis and adenomyosis. • ENDOMETRIAL CARCINOMA.
CLINICAL FINDINGS
SYMPTOMS ⚫ Symptomatic in only 30% of Patient. ⚫ Symptoms depend on location, size, changes & pregnancy status ⚫ Menstrual abnormality – Menorrhagia, metrorrhagia. ⚫ Dysmenorrhea ⚫ Dyspareunia ⚫ Infertility ⚫ Recurrent abortion ⚫ Lower abdominal or pelvic pain ⚫ Abdominal enlargement
SYMPTOMS ⚫ MENSTRUAL ABNORMALITIES – ⚫ Submucous myoma produce the most pronounced symptoms of menorrhagia, pre & post-menstrual spotting ⚫ Bleeding is due to interruption of blood supply to the endometrium, distortion & congestion of surrounding vessels or ulceration of the overlying endometrium ⚫ Pedunculated submucous areas of venous thrombosis & necrosis on the surface inter- menstrtual bleeding
SYMPTOMS ⚫ DYSMENORRHOEA – ⚫ The congestive variety may be due to associated pelvic congestion or endometriosis. ⚫ Spasmodic type is associated with extrusion of polyp and is expulsion from the uterine cavity. ⚫ INFERTILITY – ⚫ Infertility may be a major complaint. ⚫ The cause may be uterine, tubal, ovarian, peritioneal.
SYMPTOMS ⚫ PREGNANCY RELATED PROBLEMS – ⚫ Abortion, preterm labour, IUGR. ⚫ PAIN – ⚫ Fibroids are usually painless, but it may be due to some complications of the tumor or due to associated pelvic pathology. ⚫ Due to tumour – ⚫ Degeneration ⚫ Torsion of subserous pedunculated fibroid ⚫ Extrusion of polyp ⚫ Assosiated pathology – ⚫ Endometriosis ⚫ PID
⚫ PRESSURE SYMPTOMS ⚫ If large may distort or obstruct other organs like ureters, bladder or rectum urinary symptoms, hydroureter, constipation, pelvic venous congestion & LL edema ⚫ Rarely a posterior fundal tumor extreme retroflexion of the uterus distorting the bladder base urinary retention ⚫ Parasitic tumor may cause bowel obstruction ⚫ Cervical tumors causes vaginal discharge, bleeding, dyspareunia or infertility SYMPTOMS
COMPLICATIONS
COMPLICATIONS IN PREGNANCY ⚫ 2/3of women with fibroids & unexplained infertility conceive after myomectomy ⚫ Red degeneration ⚫ In the 2nd or 3rd trimester of pregnancy rapid in size vascular deprivation degeneration ⚫ Causes pain & tenderness ⚫ May initiate preterm labor ⚫ After the acute phase pregnancy will continue to term
COMPLICATIONS IN PREGNANCY DURING LABOR ⚫Uterine inertia ⚫Malpresentation ⚫Obstruction of the birth canal ⚫Cervical or isthmeic myoma necessitate CS ⚫PPH
COMPLICATIONS IN NONPREGNANT WOMEN ⚫Heavy bleeding with anemia is the most common ⚫Urinary or bowel obstruction from large parasitic myoma is much less common ⚫Malignant transformation is rare ⚫Ureteral injury or ligation is a recognized complication of surgery for myoma ⚫Postmenopausal women on hormonal therapy must be followed up with pelvic exam or USG every 6 months.
MANAGEMENT OF FIBROID
EXAMINATION ⚫ Most myoma are discovered on routine bimanual pelvic exam or abdominal examination ⚫ Retroflexed retroverted uterus obscure the palpation of myomas LABORATORY FINDINGS ⚫ Anemia ⚫ Depletion of iron reserve ⚫ Rarely erythrocytosis pressure on the ureters back pressure on the kidneys erythropoietin ⚫ Acute degeneration & infection ESR, leucocytosis, & fever
IMAGING ⚫ Pelvic USG is very helpful in confirming the Dx & excluding pregnancy / Particularly in obese . ⚫ Saline hysterosonography can identify submucous myoma that may be missed on USG ⚫ HSG will show intrauterine leiomyoma ⚫ MRI highly accurate in delineating the size, location & no. of myomas , but not always necessary ⚫ IVP will show ureteral dilatation or deviation & urinary Anomalies. HYSTROSCOPY for identification & removal of submucous myomas
DIFFERENTIAL DIAGNOSIS ⚫ Usually easily diagnosed ⚫ Exclude pregnancy ⚫ Exclude other pelvic masses -Ovarian Ca -Tubo-ovarian abscess -Endometriosis -Adenexa, omentum or bowel adherent to the uterus Exclude other causes of uterine enlargement: -Adenomyosis -Myometrial hypertrophy -Congenital anomalies -Endometrial Ca
DIFFERENTIAL DIAGNOSIS Exclude other causes of abnormal bleeding ⚫ Endometrial hyperplasia ⚫ Endometrial or tubal Ca ⚫ Uterine sarcoma ⚫ Ovarian Ca ⚫ Polyps ⚫ Adenomyosis ⚫ DUB ⚫ Endometriosis ⚫ Exogenouse estrogens Endometrial biopsy or D&C is essential in the evaluation of abnormal bleeding to exclude endometrial Ca
TREATMENT
TREATMENT DEPENDS ON: ⚫Age ⚫Parity ⚫Pregnancy status ⚫Desire for future pregnancy ⚫General health ⚫Symptoms ⚫Size ⚫Location

CERVIX SUPRAVAGINAL VAGINAL Myomectomy Hysterectomy Polypectomy Myomectomy
MANAGEMENT OF UTERINE FIBROID ⚫No treatment is required for asymptomatic small fibroid, unless if cause 12 week uterine enlargement or is the cause of infertility. ⚫For excessive heavy cycle. ⚫Progesterone only therapy: ⚫Oral ⚫Progesterone only pills. ⚫LNG releasing IUD.
⚫Combined oral contraceptive pills: used cyclically to reduce menstrual blood loss or continueously to eliminate the cycle. ⚫Dysmenorrhoea is also improved. MANAGEMENT OF UTERINE FIBROID
EMERGENCY MEASURES ⚫Blood transfusion/ PRBC to correct anemia. ⚫Emergrncy surgery indicatd for: - infected myoma -acute torsion -intestinal obstruction ⚫Myomectomy is contraindicated during pregnancy.
SPECIFIC MEASURES ⚫ Most cases asymptomatic no treatment ⚫ Postmenopausal no treatment ⚫ Other causes of pelvic mass must be excluded ⚫ Initial follow up every 6 months to determine the rate of growth of the myoma ⚫ Surgery is contraindicated in pregnancy ⚫ The only indication for myomectomy in pregnancy is torsion of a pedunculated fibroid ⚫ Myomectomy is not recommended during CS ⚫ Pregnant women with previous multiple myomectomy / especially if the cavity was entered 🡆 should be delivered by CS to risk of scar rupture in labor
SUPPORTIVE MEASURES ⚫PAP smear & endometrial sampling for all Pt with irregular bleeding ⚫Before surgery -Correct Hb -Prophylactic antibiotics -Mechanical & antibiotic bowel preparation if difficult surgery is anticipated ⚫Prophylactic heparin postoperative
