Dilation and Curettage (D and C) (2024)

What is a dilation and curettage (D&C)?

(Dilatation and Curettage, D&C)

A dilation and curettage procedure, also called a D&C, is a surgicalprocedure in which the cervix (lower, narrow part of the uterus) is dilated(expanded) so that the uterine lining (endometrium) can be scraped with acurette (spoon-shaped instrument) to remove abnormal tissues.

Other related procedures used for diagnosing and treating the endometriuminclude endometrial ablation, hysteroscopy, and hysterectomy. Please seethese procedures for additional information.

What are female pelvic organs?

The organs and structures of the female pelvis are:

• Endometrium . This is the lining of the uterus.

• Uterus (also called the womb). The uterus is a hollow, pear-shaped organ located in a woman's lower abdomen, between the bladder and the rectum. The uterus sheds its lining each month during menstruation, unless a fertilized egg (ovum) becomes implanted and pregnancy follows.

• Ovaries. Two female reproductive organs located in the pelvis in which egg cells (ova) develop and are stored and where the female sex hormones estrogen and progesterone are produced.

• Cervix. The lower, narrow part of the uterus located between the bladder and the rectum, forming a canal that opens into the vagin*, which leads to the outside of the body.

• vagin* (also called the birth canal). The passageway through which fluid passes out of the body during menstrual periods. The vagin* connects the cervix and the vulva (the external genitalia).

• Vulva. The external portion of the female genital organs.

• Fallopian tube. Two thin tubes that extend from each side of the uterus, toward the ovaries, as a passageway for eggs and sperm.

The menstrual cycle

With each menstrual cycle, the endometrium prepares itself to nourish afetus, as increased levels of estrogen and progesterone help to thicken itswalls. If implantation of the fertilized egg does not occur, the lining ofthe endometrium, coupled with blood and mucus from the vagin* and cervix(the lower, narrow part of the uterus located between the bladder and therectum), make up the menstrual flow (also called menses) that leaves thebody through the vagin*. After menopause, menstruation stops and a womanshould not have any bleeding.

Reasons for the procedure

A D&C may be used as a diagnostic or therapeutic procedure for abnormalbleeding. A D&C may be performed to determine the cause of abnormal orexcessive uterine bleeding, to detect cancer, or as part of infertility(inability to become pregnant) investigation.

Causes of abnormal bleeding include the presence of abnormal tissues, suchas fibroid tumors (benign tumors that develop in the uterus, also calledmyomas) polyps, or cancer of the endometrium or uterus. Tissues obtainedfrom the D&C can be examined under a microscope. Abnormal uterinebleeding may also be due a hormone imbalance or disorder (particularlyestrogen and progesterone) especially in women approaching menopause orafter menopause.

A suction D&C uses suction to remove uterine contents. A suctionD&C may be used following a miscarriage to remove the fetus and othertissues if they have not all been naturally passed. Infection or heavybleeding can occur if these tissues are not completely removed.

Occasionally following childbirth, small pieces of the placenta(afterbirth) remain adhered to the endometrium and are not passed. This cancause bleeding or infection. A D&C may be used to remove thesefragments so that the endometrium can heal properly.

There may be other reasons for your doctor to recommend a D&C.

Risks of the procedure

As with any surgical procedure, complications may occur. Some possiblecomplications of a D&C may include, but are not limited to, thefollowing:

• Heavy bleeding

• Infection

• Perforation of the uterine wall or bowel

• Adhesions (scar tissue) may develop inside the uterus

Patients who are allergic to or sensitive to medications, iodine, or latexshould notify their doctor.

If you are pregnant or suspect that you may be pregnant, you should notifyyour health care provider.

There may be other risks depending on your specific medical condition. Besure to discuss any concerns with your doctor prior to the procedure.

A vagin*l, cervical, or pelvic infection may interfere with a D&C.

Before the procedure

• Your doctor will explain the procedure to you and offer you the opportunity to ask any questions that you might have about the procedure.

• You will be asked to sign a consent form that gives your permission to do the procedure. Read the form carefully and ask questions if something is not clear.

• In addition to a complete medical history, your doctor may perform a complete physical examination to ensure you are in good health before undergoing the procedure. You may undergo blood tests or other diagnostic tests.

• If your procedure requires general, spinal, or epidural anesthesia, you will be asked to fast for eight hours before the procedure, generally after midnight. If your procedure is to be done under local anesthesia, your doctor will give you instructions about fasting.

• If you are pregnant or suspect that you are pregnant, you should notify your health care provider. He or she may recommend a pregnancy test prior to the procedure.

• Notify your doctor if you are sensitive to or are allergic to any medications, iodine, latex, tape, and anesthetic agents (local and general).

• Notify your doctor of all medications (prescribed and over-the-counter) and herbal supplements that you are taking.

• Notify your doctor if you have a history of bleeding disorders or if you are taking any anticoagulant (blood-thinning) medications, aspirin, or other medications that affect blood clotting. It may be necessary for you to stop these medications prior to the procedure.

• If a sedative is given before the procedure, you will need someone to drive you home afterwards.

• You may want to bring a sanitary napkin to wear home after the procedure.

• Based on your medical condition, your doctor may request other specific preparation.
