Hysteroscopy
Hysteroscopy is the exam of the inside of the cervix and uterus using a thin, lighted, flexible tube called a hysteroscope. Your healthcare provider inserts the device through the vagina.
Your provider may use hysteroscopy to:
- Take a tissue sample (biopsy)
- Remove polyps or fibroid tumors
- Prevent bleeding by destroying tissue using electric current, freezing, heat, or chemicals
Your provider may do a hysteroscopy in his or her office or in an outpatient center. You may have local or no anesthesia. Procedures that are more complex may be done in the operating room under local, regional, or general anesthesia.
Diagnostic hysteroscopy identifies structural irregularities in your uterus that may be causing abnormal bleeding. Hysteroscopy may also be used to confirm the results of other tests, such as an ultrasound or hysterosalpingography (HSG). HSG is an X-ray dye test used to check whether your fallopian tubes are blocked. Blocked fallopian tubes may make it difficult to become pregnant.
Operative hysteroscopy treats an abnormality detected during a diagnostic hysteroscopy. Your provider may perform a diagnostic and operative hysteroscopy at the same time, avoiding the need for a second surgery. During operative hysteroscopy, your surgeon uses a device to remove abnormalities that may be causing abnormal uterine bleeding.
Endometrial ablation is a procedure that treats abnormal uterine bleeding. Your surgeon uses the hysteroscope to look inside your uterus before using a device to destroy your uterine lining.
Hysteroscopy is primarily used to identify and treat conditions that cause abnormal uterine bleeding, heavy menstrual bleeding, irregular spotting between periods and bleeding after menopause.
Your doctor may perform hysteroscopy to diagnose and correct the following uterine conditions:
- Polyps and fibroids: Hysteroscopy is used to find and remove these uterine structural abnormalities. Surgical removal of a polyp is called a hysteroscopy polypectomy. Surgical removal of a fibroid is called a hysteroscopy myomectomy.
- Adhesions: Also known as Asherman’s syndrome, uterine adhesions are bands of scar tissue that can form in your uterus and may lead to changes in menstrual flow and cause infertility. Hysteroscopy can help your doctor locate and remove the adhesions.
- Septums: Hysteroscopy can help determine whether you have a uterine septum, a malformation (defect) of the uterus that’s present from birth.
Hysteroscopy may also be used to:
- Diagnose the cause of repeated miscarriages or fertility problems.
- Locate an intrauterine device (IUD).
- Diagnose and remove placental tissue after birth.
Your surgeon will review your medical history and evaluate your current health to determine whether a hysteroscopy is appropriate. Although there are many benefits associated with hysteroscopy, it’s not right for everyone. For example, you shouldn’t have a hysteroscopy if:
- You’re pregnant.
- You have a pelvic infection.
If your periods are regular, your surgeon will likely recommend scheduling your hysteroscopy for the first week after you stop bleeding. This timing will allow the best view of the inside of your uterus. If you have irregular menstrual cycles, you may need to work with your surgeon to find the best time for your hysteroscopy. The procedure can take place at any time if you’ve gone through menopause.
Your surgeon will ensure you’re a good candidate for a hysteroscopy, talk you through the procedure and answer any questions you may have. You’ll receive instructions so you’re prepared for your procedure.
Your provider may:
- Take a medical history and ask what medicines you’re taking, including vitamins and supplements. Before the procedure, you may need to stop taking medications that prevent blood clotting (anticoagulants), including aspirin.
- Perform a physical exam, pelvic exam and pregnancy test. You may need to take a blood test or complete other diagnostic tests depending on the specifics of your procedure.
- Explain how to prepare, including the clothes you should wear for the procedure, whether you’ll need to fast beforehand and whether you’ll need someone to drive you home after your hysteroscopy.
On the day of the procedure, you’ll be asked to empty your bladder and change into a hospital gown. You may receive anesthesia or a sedative to help you relax. The type of anesthesia you receive depends on whether the hysteroscopy will take place in a hospital or your surgeon’s office and whether other procedures will occur simultaneously.
You’ll be positioned on the exam table with your legs in stirrups. Once you’re in position, your surgeon will:
- Perform a pelvic exam.
- Dilate (open) your cervix so the hysteroscope can be inserted.
- Insert the hysteroscope through your vagina and cervix into your uterus.
- Send a liquid solution through the hysteroscope and into your uterus, gently expanding it and clearing any blood or mucus. This step allows your surgeon to view your uterus, uterine lining and fallopian tubes.
- Inspect your uterine cavity and the openings of your fallopian tubes. The light from the hysteroscope makes it easier for your surgeon to get a clear view.
- Insert surgical instruments through the hysteroscope that can be used to remove any irregular abnormalities (if surgery is needed).
A hysteroscopy can last anywhere from five minutes to more than an hour. The length of the procedure depends on whether it’s diagnostic or operative and whether an additional procedure, such as laparoscopy, is done simultaneously. Diagnostic hysteroscopy usually takes less time than operative.
If you received anesthesia during your hysteroscopy, you might be observed for several hours in the recovery room. You may have some cramping or light bleeding that lasts for a few days. It’s also not unusual to feel somewhat faint or sick immediately following your procedure.
Will I have to stay in the hospital overnight after a hysteroscopy?
Hysteroscopy is considered minor surgery and usually doesn’t require an overnight hospital stay. If your provider is concerned about your reaction to anesthesia, you may need to stay overnight.
