Myomectomy is a surgical procedure to remove uterine fibroids, benign or non-cancerous growths appearing in your uterus. Many women with uterine fibroids do not experience any symptoms. However, some women may experience symptoms that are mild and they include heavy and prolonged menstrual bleeding, bleeding between periods, pelvic pain, lower back pain, pain during intercourse and urinary problems. Rarely may you have difficulty emptying your bladder, difficulty moving your bowels, anemia due to heavy menstrual bleeding and reproductive problems such as infertility.
Myomectomy is the treatment of choice in women with fibroids who are willing to have children in the future. Myomectomy removes only the fibroids and leaves your uterus intact and increases your chances of pregnancy.
Before your surgery, gonadotropin-releasing hormone analogue (GnRH-a) therapy which lowers estrogen levels may be used to shrink the uterine fibroids thus reducing the risk of excessive bleeding during the surgery.
Depending on the size, location and number of fibroids, your surgeon may choose one of three surgical approaches to remove the fibroids:
Hysteroscopy: This is an outpatient surgical procedure and is performed under general anesthesia or spinal anesthesia. Your doctor uses a tiny viewing tool called a hysteroscope which is passed through your vagina and cervix into your uterus to look inside the uterus. Your doctor can see the inside of the uterus to examine the lining of the uterus (endometrium) and remove the fibroids. Your doctor may also take tissue samples for biopsy. Fibroids located on the inner wall of the uterus that have not gone deep within the wall of the uterus can be removed using this technique.
Laparoscopy: A laparoscopic myomectomy procedure is a minimally invasive surgery during which a laparoscope, a long thin instrument attached with a camera is used. A small incision is usually made below the navel and a laparoscope is inserted through this incision. Carbon dioxide gas is injected into the abdominal cavity using a special needle to create more space to work. Your surgeon identifies and removes the fibroids. During the procedure tissue samples, can also be taken for biopsy. This procedure is preferred option to remove one or two fibroids up to 5.1 cm across that are grow on the outside of the uterus.
Laparotomy: A laparotomy is the surgical removal of fibroids through a large incision in the lower abdomen. If the fibroids are large and many in number or grown deep into the uterine wall your doctor may opt for laparotomy. Urinary or bladder problems can be corrected using laparotomy.
Myomectomy is a treatment option if you have anemia and pain or pressure not relieved with medications. Myomectomy is also done if the fibroids have changed the uterus to cause infertility or repeated miscarriages as this method improves your chances of becoming pregnant even after the procedure. After myomectomy, your pelvic pain and bleeding from fibroids is reduced and your chances of having a baby is improved. If the fibroids are large and are in more numbers they can re-grow after surgery.
The possible complications of myomectomy include infection, scar tissue formation, damage to the bladder or bowel, and rupture of the uterine scars in late pregnancy or during labor. Rarely a myomectomy causes uterine scarring that can lead to infertility.
Because fibroids can grow back, women those who are planning to become pregnant in the future must try to conceive as early as possible after the myomectomy procedure. However, following surgery your doctor will advise you to wait for 4 to 6 months until the uterus heals. Before undergoing any treatment for infertility your doctor may recommend a hysterosalpingogram, an X-ray test to check the uterus and fallopian tubes.
The incisions made in the wall of the uterus to remove fibroids may cause placental problems and improper functioning of the uterus during labor may need a caesarean delivery. Rarely, a hysterectomy may be needed if the uterus is grown too large with fibroids.
