Definition A hysteroscope is a small metal tube connected to a light source and camera. It magnifies the cervical opening, uterine cavity, and the openings of the fallopian tubes during a procedure called hysteroscopy.
Hysteroscopy may be:
diagnostic, in which case it is only used to view the organs and observe any obvious abnormalities
therapeutic, in which case surgery is done through the scope
Who is a candidate for the procedure? A hysteroscopy may be recommended:
if the source of bleeding is not found through a D & C
to aid in taking a biopsy, or tissue sample, from the lining of a woman's uterus after precancerous changes have been noted
to check the upper part of the cervix to see if a cancer stems from the cervix or the uterus
if a woman's medical history or a test suggests she has a uterine polyp or fibroid that might be removed by hysteroscopy
How is the procedure performed? A hysteroscopy is usually done in the first 2 weeks of a woman's menstrual cycle. This ensures she is not pregnant. It takes about 20 to 45 minutes and can be done:
First, the cervix and vagina are cleansed. The cervix is opened so that the scope can be inserted into the uterus. The uterus is inflated with fluid or a harmless gas to make it easier to view. Any suspicious lesions (polyps, fibroids, ulcers, or growths) may be biopsied or removed using small tools placed in the scope. This tissue is sent for microscopic analysis. Pictures may be taken, too, before and after any surgery is done.
What happens right after the procedure? Recovery usually takes less than 2 hours. Results will vary according to the findings.
If a uterine polyp or fibroid was removed, symptoms of abnormal bleeding generally improve. They may recur if the base of the polyp or fibroid was not completely removed.
If precancerous changes in the uterine lining were diagnosed, further treatment with high-dose progesterones or hysterectomy may be needed.
The results and findings will be discussed during a follow-up visit in the doctor's office.
a puncture of the uterus, which may injure the bowel or bladder
infection of the cervix, uterine lining, or fallopian tubes
vaginal bleeding from blood vessels in the uterus or a torn cervix
too much fluid, which can cause salt imbalance, fluid in the lungs known as pulmonary oedema, or kidney shutdown, known as acute renal failure. This is more common when the procedure takes a long time and large amounts of fluid are used in the uterus.
