Endometrial ablation is a procedure that destroys (ablates) the uterine lining, or endometrium. This procedure is used to treat dysfunctional or abnormal uterine bleeding. Sometimes a lighted viewing instrument (hysteroscope) is used to see inside the uterus. Endometrial ablation can be done by:
- Laser beam (laser thermal ablation).
- Heat (thermal ablation), using:
- A balloon filled with saline solution that has been heated to 85°C (185°F) (thermal balloon ablation).
- Normal saline (heated free fluid).
- Electricity, using a resectoscope with a loop or rolling ball electrode.
The endometrium heals by scarring, which usually reduces or prevents uterine bleeding.
Endometrial ablation may be done in an outpatient facility or your doctor’s office. The procedure can take up to about 45 minutes. The procedure may be done using a local or spinal anesthesia. And general anesthesia is sometimes used.
