Types of Hysterectomy

By Extent of Removal

By Surgical Route

"Vaginal hysterectomy is the procedure of choice unless this route is contraindicated. LH offers no advantage for women in whom VH is possible... The ideal place for LH is as a replacement for laparotomy."

Surgical Steps (Abdominal Approach)

1. Divide round ligaments (bilaterally) with electrocautery or ligature
2. Incise anterior leaf of broad ligament, develop bladder flap
3. If salpingo-oophorectomy is planned: identify ureters, doubly clamp and divide infundibulopelvic ligaments (ovarian vessels)
4. If ovaries are to be preserved: clamp utero-ovarian vessels
5. Dissect bladder off the cervix inferiorly
6. Clamp, divide, and suture-ligate uterine vessels at the internal cervical os
7. Serially clamp and divide cardinal and uterosacral ligaments
8. Perform colpotomy (circumferential incision around cervix at vaginal junction)
9. Close vaginal cuff with interrupted or running absorbable sutures, incorporating uterosacral ligaments for apical support

Indications

Benign Indications

• Intractable dysmenorrhea
• Cervical intraepithelial neoplasia (CIN) - as treatment of last resort for recurrent high-grade CIN
• Obstetric emergencies (e.g., uterine rupture, intractable postpartum hemorrhage)
• Benign ovarian/pelvic masses

• Berek & Novak's Gynecology, p. 605

Malignant/Premalignant Indications

• Endometrial carcinoma
• Cervical carcinoma (radical hysterectomy)
• Recurrent/refractory CIN
• Uterine sarcoma

Concomitant Procedures

• Bilateral salpingo-oophorectomy (BSO): Optional. In premenopausal women with average ovarian cancer risk, oophorectomy at hysterectomy is associated with increased long-term mortality from cardiovascular disease - ovarian conservation should be strongly considered.
• Opportunistic salpingectomy: Bilateral salpingectomy is increasingly performed at the time of hysterectomy to reduce ovarian cancer risk (the fallopian tube is implicated in the pathogenesis of high-grade serous carcinoma).
• Sentinel lymph node (SLN) mapping: For endometrial cancer, indocyanine green (ICG) injected into the cervix at 3 and 9 o'clock positions, traced to pelvic nodes; preferred over full lymphadenectomy to reduce morbidity.
• McCall culdoplasty: Performed at vaginal hysterectomy for apical support.

Preoperative Considerations

• Health assessment including cardiopulmonary fitness
• Total vs. supracervical: No routine advantage to supracervical; avoid if cervical/uterine pathology present
• Route decision: Based on anatomy, uterine size/disease, patient wishes, surgeon training
• Concurrent procedures: Pelvic floor repair, appendectomy, cholecystectomy, abdominoplasty
• Tissue morcellation: Avoid if malignancy is known or suspected (risk of disseminating occult malignancy)

Postoperative Complications

Intraoperative

• Hemorrhage (1.4-2.6% in vaginal hysterectomy)
• Urinary tract injury (ureter, bladder)
• Bowel injury
• Conversion to open approach (laparoscopic cases)

Postoperative

Route Comparison Summary

Key Points (Evidence-Based)

1. Hysterectomy is one of the most commonly performed surgeries in the US.
2. Vaginal hysterectomy is the preferred route unless contraindicated.
3. Randomized clinical trials do not show any advantage of robotic or single-port hysterectomy over conventional laparoscopic hysterectomy.
4. There is no routine advantage to supracervical over total hysterectomy.
5. Bilateral salpingo-oophorectomy at hysterectomy in premenopausal women at average risk increases long-term mortality from cardiovascular disease - ovarian conservation is strongly recommended.
6. Opportunistic salpingectomy at time of hysterectomy is encouraged to reduce ovarian cancer risk.

Recent Evidence (2023-2024)

• A 2023 Cochrane systematic review on surgical approaches to hysterectomy for benign disease confirms the minimally invasive advantage over laparotomy (PMID 37642285).
• A 2024 meta-analysis on long-term outcomes of hysterectomy with bilateral salpingo-oophorectomy found significant associations with cardiovascular and metabolic morbidity when performed in premenopausal women (PMID 37364803).
• A 2023 JAMA Surgery systematic review supports opportunistic salpingectomy at time of hysterectomy for primary prevention of ovarian cancer (PMID 37672283).
