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.
