Dilatation and Curettage
Dilatation and curettage (D & C) is a gynecological procedure in which the lining of the uterus (endometrium) is scraped away.
D & C is commonly used to obtain tissue for microscopic evaluation to rule out cancer. D & C may also be used to diagnose and treat heavy menstrual bleeding, and to diagnose endometrial polyps and uterine fibroids. A D & C can be used as a treatment as well, to remove pregnancy tissue after a miscarriage, incomplete abortion, or childbirth. Endometrial polyps may be removed, and sometimes benign uterine tumors (fibroids) may be scraped away. D & C can also be used as an early abortion technique up to 16 weeks.
D & C is usually performed under general anesthesia, although local or epidural anesthesia can also be used. A local lessens risk and costs, but the woman will feel cramping during the procedure. The type of anesthesia used often depends upon the reason for the D & C.
In the procedure (which takes only minutes to perform), the doctor inserts an instrument to hold open the vaginal walls, and then stretches the opening of the uterus to the vagina (the cervix) by inserting a series of tapering rods, each thicker than the previous one, or by using other specialized instruments. This process of opening the cervix is called dilation.
Once the cervix is dilated, the physician inserts a spoon-shaped surgical device called a curette into the uterus. The curette is used to scrape away the uterine lining. One or more small tissue samples from the lining of the uterus or the cervical canal are sent for analysis by microscope to check for abnormal cells.
Although simpler, less expensive techniques such as a vacuum aspiration are quickly replacing the D & C as a diagnostic method, it is still often used to diagnose and treat a number of conditions.
Because opening the cervix can be painful, sedatives may be given before the procedure begins. Deep breathing and other relaxation techniques may help ease cramping during cervical dilation.
A woman who has had a D & C performed in a hospital can usually go home the same day or the next day. Many women experience backache and mild cramps after the procedure, and may pass small blood clots for a day or so. Vaginal staining or bleeding may continue for several weeks.
Most women can resume normal activities almost immediately. Patients should avoid sexual intercourse, douching, and tampon use for at least two weeks to prevent infection while the cervix is closing and to allow the endometrium to heal completely.
The primary risk after the procedure is infection. Signs of infection include:
- heavy bleeding
- severe cramps
- foul-smelling vaginal discharge
A woman should report any of these symptoms to her doctor, who can treat the infection with antibiotics before it becomes serious.
D & C is a surgical operation, which carries certain risks associated with general anesthesia. Rare complications include puncture of the uterus (which usually heals on its own) or puncture of the bowel or bladder (which require further surgery to repair).
Removal of the uterine lining causes no side effects, and may be beneficial if the lining has thickened so much that it causes heavy periods. The uterine lining soon grows again normally, as part of the menstrual cycle.
Endometrial polyps — A growth in the lining of the uterus (endometrium) that may cause bleeding and can develop into cancer.
Epidural anesthesia — A type of anesthesia that is injected into the epidural space of the spinal cord to numb the nerves leading to the lower half of the body.
Uterine fibroid — A noncancerous tumor of the uterus that can range from the size of a pea to the size of a grapefruit. Small fibroids require no treatment, but those causing serious symptoms may need to be removed.

dilatation and curettageA common gynaecological operation that has not been entirely replaced by more recent methods such as low pressure suction curettage (see PIPELLE) or endoscopy. The opening into the womb is temporarily widened and a long, spoon-shaped instrument (a curette) is used to scrape the inside. This is done to treat abnormal bleeding, to remove unwanted tissue or to obtain a specimen for examination. Commonly referred to as D and C.
