Hysterectomy with "adnexectomy" rather than a straightforward removal of the Fallopian tubes and ovaries, usually implies a more extensive operation for a non benign indication. Most often, this is performed for ovarian masses. Also may involve taking the omentum (pad of fat in the upper abdomen) and lymph glands in the pelvis and sometimes around the aorta. Yes, this can be done by keyhole in which case recovery is usually quicker (4-6 wks) with an average hospital stay of 48hrs. However, if this was done via a midline laparotomy, the average hospital stay is usually 4 days and full recovery could take up to 3 months.
