Some issues Dr. Quan M. Dau, MD can help you with:

Cryotherapy

Cryotherapy is the targeted use of extreme cold to destroy unhealthy or unwanted tissue. The doctor applies the cold on the skin or injects it through a needle to reach the inside of the body, where it freezes away the problem tissue. Cryotherapy is often used to remove minor skin problems such as warts or skin tags, and it is also used to treat some small tumors.

To achieve the cold temperatures needed for cryotherapy, liquid nitrogen or argon gas is passed through a tube, which becomes cold enough to freeze cells on contact. Alternatively, liquid nitrogen can be swabbed directly onto the skin or via a spray, which applies only a specific, small amount to the skin at a time.

Because the area treated is typically very small, cryotherapy is not usually painful. There may be a sensation of cold and possibly some slight discomfort. Cryotherapy is very fast and can easily be performed in a doctor's office. It also doesn't require stitches, because there is no cutting involved. These benefits make cryotherapy a good choice for many issues, including:

  • Common warts
  • Genital warts
  • Skin tags
  • Age spots
  • Some skin cancers
  • Cervical cancer
  • Prostate cancer
  • Retinoblastoma, cancer that occurs in the eye

Depending on the procedure, it usually takes three to four weeks to heal after cryotherapy. If it was done internally, patients may feel sore or have a small amount of swelling the first day afterwards. If cryotherapy was performed on the skin, patients will have a scab where their tissue was removed. Keep it clean and dry so it can heal.

Hysterectomy (Uterus Removal)

A hysterectomy is an extremely common surgery performed to remove the uterus. Sometimes the fallopian tubes, ovaries, or cervix will be removed as well. A woman who has had a hysterectomy will no longer have periods and cannot get pregnant.

There are a variety of reasons that women have hysterectomies, including:

  • Heavy bleeding or pain, such as that due to fibroids, endometriosis, or adenomyosis
  • Cancer
  • Prolapsed uterus, where the pelvic muscles can no longer completely hold the uterus in place

It is important to note that having any of these conditions does not necessarily mean that a hysterectomy is necessary. There are other available treatment options in most cases.

Although the uterus is responsible for a period, it is the ovaries that control the hormonal changes that women go through every month. So if a woman has a hysterectomy but keeps her ovaries, she might still experience hormonal swings every month even if she no longer has a period. Alternately, if a younger woman has a hysterectomy where her ovaries as removed, she will essentially be in immediate menopause.

A hysterectomy can be performed traditionally through one large cut in the abdomen, laparoscopically using tiny incisions and small tools, or through the vagina. Full recovery may take four to six weeks. After a hysterectomy, patients might experience sexual changes such as vaginal dryness or a change in libido. It is common to experience strong emotions after a hysterectomy, including both grief and relief. If a patient's ovaries were removed, they may be at higher risk for certain diseases, such as heart disease and osteoporosis. Taking hormonal birth control might reduce this risk.

Hysteroscopy

A hysteroscopy is a diagnostic procedure performed to examine the inside of the uterus. A thin tube with a camera and light at the end, called a hysteroscope, is inserted through the vagina. It allows the physician to view the cervix and uterine walls. Sometimes, gas or liquid is used to expand the uterus and allow a better view. If necessary, tiny instruments can also be passed through the tube and used for certain procedures, such as taking a biopsy or removing a polyp.

Hysteroscopy is often done to figure out the cause of abnormal menstrual bleeding. However, it can also be used to:

  • Identify the cause of recurrent miscarriage
  • Remove polyps or fibroids, non-cancerous growths in the uterus
  • Remove adhesions, scar tissue within the uterus
  • Identify uterine septums, a wall of tissue dividing the uterus
  • Perform ablation, the removal of excess uterine lining

If surgery is necessary, hysteroscopy is often used along with laparoscopy, a kind of surgery performed through small incisions in the abdomen. Tiny tools are passed through the incisions, and the hysteroscope guides the doctors while surgery is performed.
