Abdominal hysterectomy involves the surgical removal of the uterus, with various types including total, subtotal, and radical hysterectomy depending on the extent of removal. The procedure allows for thorough examination and intervention on pelvic organs and can include simultaneous surgeries, though it carries higher risks and postoperative complications compared to vaginal hysterectomy. Advantages include broader exploratory capabilities and effectiveness in addressing tubo-ovarian issues, while disadvantages encompass increased pain, longer recovery, and higher morbidity rates.
