What’S A Dilation And Curettage?

A dilation and curettage is a procedure in which the cervix is gently opened and the lining of the uterus is removed with a thin instrument. It is most often done to diagnose or treat abnormal uterine bleeding, to remove tissue left after a miscarriage, or to clear the uterus after certain pregnancy-related events. Doctors sometimes shorten the name to D&C.

It is a common procedure. It is also one that carries real questions about pain, recovery, and what the tissue findings actually mean. Here is what the evidence supports and where the honest limits are.

What Is a Dilation and Curettage and How Does It Work?

The two words in the name describe the two steps. Dilation means opening the cervix, the narrow passage at the bottom of the uterus. Curettage means scraping or suctioning away tissue from the inner lining of the uterus, called the endometrium.

The cervix is normally closed and firm. To pass an instrument into the uterus, it has to be widened. This can be done with thin rods that are gradually increased in size, or with medication that softens and opens the cervix. Once the cervix is open, the doctor uses a small spoon-shaped tool called a curette, or a suction device, to remove tissue.

The procedure is usually short. In many cases it takes only a few minutes once the cervix is open. It may be done in an operating room, a clinic, or an emergency setting, depending on why it is needed.

One clarification worth knowing: a D&C is not the same as a dilation and evacuation, sometimes called a D&E. A D&E is typically used later in pregnancy and involves different instruments and techniques. The two terms are often confused.

Why Would Someone Need a Dilation and Curettage?

There are two broad reasons: to diagnose a problem or to treat one. Sometimes a single procedure does both.

Diagnostic reasons include abnormal uterine bleeding, especially bleeding after menopause, or bleeding that does not have a clear cause on imaging. A D&C lets a pathologist examine the tissue under a microscope to look for abnormal cells or other changes.

Treatment reasons include removing tissue that remains in the uterus after a miscarriage or after delivery. Retained tissue can cause ongoing bleeding, cramping, or infection, so clearing it can resolve those problems.

A D&C may also be used to remove a small growth such as a polyp, or to sample the lining when a biopsy done in the office does not give enough information.

In many situations today, other options come first. An office endometrial biopsy can often sample the lining without anesthesia or an operating room. A procedure called hysteroscopy, which uses a small camera to look inside the uterus, allows a doctor to see and target specific areas. Whether a D&C is the best choice depends on the reason, the amount of tissue involved, and the setting.

What Happens During the Procedure?

Most people receive some form of anesthesia or pain control. This ranges from local numbing to sedation to general anesthesia, depending on the situation and the setting.

The general sequence looks like this:

• The cervix is opened, either with instruments or with medication given beforehand.
• A speculum holds the vagina open so the cervix can be reached.
• The doctor passes a thin instrument through the cervix into the uterus.
• Tissue is removed with a curette or suction.
• The tissue is sent to a lab for examination if a diagnosis is needed.

The procedure itself is usually brief. Most of the time in the room is spent on preparation and anesthesia rather than the tissue removal.

You should not feel the scraping itself if anesthesia is working. Cramping afterward is common and often described as similar to strong menstrual cramps.

What Does Recovery Look Like?

Recovery is typically short. Many people go home the same day and return to normal activities within a day or two. Some need more time, especially if the procedure was done for a pregnancy-related reason.

Common after-effects include:

• Cramping, often like period cramps, for a day or so
• Light bleeding or spotting for several days
• Feeling tired for a short time from the anesthesia

Most clinicians advise avoiding inserting anything into the vagina, including tampons and intercourse, for a period afterward to lower infection risk. The exact length varies by clinician and situation. Ask your own doctor what they recommend for you rather than relying on a general rule.

Call your doctor if you have heavy bleeding that soaks pads quickly, fever, worsening pain, or foul-smelling discharge. These can be signs of infection or other problems that need attention.

What Are the Risks and Complications?

A D&C is generally considered a low-risk procedure, but no procedure is risk-free. The evidence on complication rates comes largely from clinical experience and observational data rather than large randomized trials, which is worth being honest about.

Possible complications include:

• Infection of the uterus
• Bleeding that is heavier than expected
• Injury to the cervix or uterus, including a rare puncture of the uterine wall
• Scarring inside the uterus, which can affect future fertility in uncommon cases
• Reactions to anesthesia

The risk of scarring, called intrauterine adhesions, is a real concern but uncommon after a single uncomplicated procedure. It becomes more of a concern after repeated procedures or after a procedure done in the setting of infection.

If you are planning future pregnancies, it is reasonable to ask your doctor whether a D&C is necessary or whether another approach might achieve the same goal with less impact on the uterus. That conversation is worth having before the procedure, not after.

How Does a D&C Compare to Other Procedures?

Several procedures sample or clear the uterus. They are not interchangeable, and which one fits depends on the goal.

An office biopsy is often tried first when the goal is to check the lining for abnormal cells, because it avoids anesthesia and an operating room. A D&C removes more tissue and may be chosen when a larger sample is needed or when there is tissue to clear rather than just sample.

Hysteroscopy is often combined with a D&C. The camera helps the doctor see the inside of the uterus while the tissue is removed, which can make the procedure more precise.

What Do the Results Mean?

When tissue is sent to a lab, a pathologist examines it under a microscope. Results usually come back within days to a couple of weeks, depending on the lab.

Findings can include normal lining, benign growths such as polyps, inflammation, hormonal changes, or abnormal cells. Some results are clear and some require follow-up testing or monitoring.

If the result is normal, that is reassuring but does not always explain the original symptom. Bleeding can have many causes, and a normal tissue sample does not rule out every possibility. If bleeding continues, further evaluation may be needed.

If the result shows abnormal cells, your doctor will explain what type and what the next steps are. This is a situation where asking specific questions about what the finding means for you is important.

Is a D&C Painful?

With anesthesia, the procedure itself is not painful. Afterward, cramping is common and usually manageable with over-the-counter pain relief, though you should follow your doctor’s guidance on which medications are appropriate for you.

The level of discomfort varies. People who have had a D&C for a miscarriage often describe a mix of physical and emotional recovery. The procedure addresses the physical side; the emotional side may need separate support.
