Hysterectomy

Hysterectomy is the surgical removal of the uterus. It is one of the most common major gynecologic operations and is performed for both benign conditions — such as fibroids, abnormal uterine bleeding, endometriosis, and prolapse — and gynecologic cancers. The uterus may be removed with or without the cervix, and the operation can be carried out by abdominal, vaginal, or laparoscopic routes.

Definition

Hysterectomy is the surgical removal of the uterus; in a total hysterectomy the cervix is also removed, while in a subtotal (supracervical) hysterectomy the cervix is preserved.

Scope

This topic covers the definitions and types of hysterectomy (total versus subtotal, and the surgical routes), the principal indications, and the comparative evidence on approach. It treats hysterectomy as a reference subject within gynecologic surgical procedures and does not provide perioperative or individualized advice.

Core questions

• When is removal of the uterus indicated rather than a uterus-conserving or medical treatment?
• How do total and subtotal hysterectomy differ, and what is removed in each?
• Which surgical route — abdominal, vaginal, or laparoscopic — best suits a given case?

Key concepts

• Total versus subtotal (supracervical) hysterectomy
• Abdominal, vaginal, and laparoscopic routes
• Radical hysterectomy for malignancy
• Benign indications (fibroids, bleeding, prolapse)
• Recovery and route-specific complications
• Loss of fertility as a consequence

Mechanisms

Hysterectomy detaches the uterus from its vascular pedicles and supporting ligaments and removes it, with or without the cervix. The route determines exposure and recovery: the abdominal route gives wide access for large uteri or complex disease, the vaginal route avoids an abdominal incision, and the laparoscopic route uses small ports and a camera. Randomized comparison shows vaginal and laparoscopic approaches generally permit faster return to normal activity than abdominal surgery, while each route carries a distinct complication profile, so route selection weighs uterine size, pathology, prior surgery, and surgeon experience (Garry et al., 2004; Aarts et al., 2015).

Clinical relevance

Hysterectomy resolves uterine-source bleeding and is definitive for many benign conditions, but it ends fertility and is a major operation, so it is one option among several for benign disease. This entry describes how the operation is classified and studied; treatment decisions belong to a clinician and patient assessing the specific situation.

Epidemiology

Hysterectomy is among the most frequently performed major operations in women. Nationwide United States data document both a gradual decline in inpatient volume and a marked shift from abdominal to minimally invasive (laparoscopic and robotic-assisted) routes for benign indications over recent decades (Wright et al., 2013).

History

Hysterectomy evolved from high-risk nineteenth-century abdominal and vaginal operations into a routine procedure as anaesthesia, asepsis, and haemostatic technique matured. The late twentieth century added laparoscopic hysterectomy, and large practice-pattern studies have since charted the migration of benign hysterectomy toward minimally invasive routes (Wright et al., 2013).

Debates

Should the cervix be removed (total) or preserved (subtotal)?

Subtotal hysterectomy was promoted as potentially preserving sexual and pelvic-floor function, but comparative evidence has not shown clear functional advantages and leaves a cervix that still requires screening, so total hysterectomy remains the more common choice for benign disease.

Which route should be preferred for benign hysterectomy?

Trial and pooled evidence favour vaginal or laparoscopic over abdominal hysterectomy for faster recovery when feasible, but uterine size, pathology, and surgeon skill constrain the choice, so no single route is universally preferred.

Frequently asked questions

What is the difference between a total and a subtotal hysterectomy?

In a total hysterectomy both the uterus and the cervix are removed; in a subtotal (supracervical) hysterectomy the body of the uterus is removed but the cervix is left in place. A retained cervix still requires routine cervical screening.

Does a hysterectomy always remove the ovaries?

No. Hysterectomy removes the uterus; the ovaries and fallopian tubes are removed only if a separate oophorectomy or salpingectomy is also performed. The decision about the ovaries is made independently of the decision to remove the uterus.
