Loop Diathermy

Loop diathermy is a treatment designed to remove abnormal cells from the cervix. The 'loop' treatment involves removing the abnormal cells but keeping them intact for laboratory testing. The Loop diathermy procedure takes less than 30 minutes and is performed as an outpatient, under local anaesthetic.

Using a speculum different solutions are applied to the cervix to spotlight the treatment area, the cervix is then desensitised using local anaesthetic. The loop is used to remove the abnormal area for testing in the laboratory and it simultaneously “seals” the area on the cervix to prevent bleeding. Loop diathermy is painless, and after the procedure medicated cream may be offered to prevent loop diathermy infection.
