Hysterectomy

Definition

Types by Extent

A total hysterectomy is preferred over subtotal because persistence of symptoms (e.g., bleeding, pain) may occur from the cervical stump. - Bailey and Love's Short Practice of Surgery, 28th Ed.

Surgical Routes

1. Abdominal Hysterectomy (AH)

• Performed via laparotomy (open incision)
• Highest morbidity, longest hospital stay
• Reserved for very large uteri, extensive adhesions, or when minimally invasive access is not safe
• Also indicated when morcellation is required and malignancy is known/suspected

2. Vaginal Hysterectomy (VH)

• Performed entirely through the vagina; no abdominal incision
• Lower complication rates and shorter hospital stays than abdominal approach
• Preferred when anatomy is suitable; no advantage gained from laparoscopy if VH is feasible

3. Laparoscopic Hysterectomy (LH)

• Introduced in 1989; grew to ~15.5% of hysterectomies by 2006
• Includes: Laparoscopically-Assisted Vaginal Hysterectomy (LAVH), Total Laparoscopic Hysterectomy (TLH), and Laparoscopic Supracervical Hysterectomy (LSH)
• Complication rates now similar to VH, with both being lower than AH
• Benefits: less postoperative pain, faster recovery, better quality of life at 6 weeks and 12 months
• Hospital readmission rates may be even lower than other techniques
• Costs are higher than VH or AH, but early discharge reduces the overall cost

4. Robotic-Assisted Hysterectomy

• FDA approved in 2005; accounted for 8.2% of hysterectomies by 2010
• Compared to standard laparoscopic hysterectomy: reduced estimated blood loss, shorter hospital stay, similar operative time (~117 min vs. ~118 min)
• Conversion rates are 4x lower than standard laparoscopic approach
• Higher procedural cost

The ideal role for laparoscopic hysterectomy is as a replacement for laparotomy; it offers no advantage over vaginal hysterectomy when VH is feasible. - Berek & Novak's Gynecology

Indications

Benign Indications

• Uterine fibroids (leiomyomata) - heavy menstrual bleeding, mass effects, pain
• Adenomyosis - diffuse infiltration of endometrial glands into myometrium; causes heavy and painful periods
• Endometriosis - especially when fertility is no longer desired
• Abnormal/Heavy Uterine Bleeding (HUB/HMB) - refractory to medical treatment or endometrial ablation
• Uterovaginal prolapse
• Chronic Pelvic Pain (CPP) - only after at least 6 months of pain with no otherwise correctable pathology (ACOG criteria); 77% of women with central pelvic pain report relief
• Pelvic Inflammatory Disease (PID) - severe or recurrent

Gynecological Oncology Indications

• Endometrial (uterine) cancer - primary treatment
• Cervical cancer - radical hysterectomy
• Ovarian cancer - as part of surgical staging/debulking
• Recurrent high-grade CIN (Cervical Intraepithelial Neoplasia) - treatment of last resort; also appropriate when co-occurring pathology (fibroids, prolapse) requires hysterectomy
• Uterine sarcoma (e.g., leiomyosarcoma)
• Gestational trophoblastic neoplasia

Obstetric Indications (Emergency)

• Postpartum hemorrhage unresponsive to conservative measures
• Placenta accreta spectrum (PAS) - may require primary or delayed hysterectomy
• Uterine rupture

Contraindications / When to Consider Alternatives

• Women who desire future fertility (myomectomy, endometrial ablation, or UAE preferred)
• Hysterectomy is generally not indicated for uncomplicated chronic pelvic pain without structural pathology
• Before surgery for pelvic pain, the PREPARE mnemonic should be applied: Procedure, Reason/indication, Expectations, nonsurgical options as Alternatives, and Risks/Expense

Complications

Intraoperative

• Hemorrhage / blood transfusion
• Bladder injury (vesicovaginal fistula risk: 1 in 1,250 after all hysterectomies; 1 in 455 after laparoscopic; 1 in 1,000 after abdominal; 1 in 5,000 after vaginal)
• Ureteral injury
• Bowel injury
• Vascular injury

Postoperative

• Wound infection / pelvic abscess
• Urinary tract infection
• Vault hematoma or dehiscence
• Venous thromboembolism (DVT / PE)
• Bladder or bowel dysfunction
• Premature menopause (if ovaries also removed - surgical menopause)
• Sexual dysfunction (changes in vaginal length/sensation)
• Psychological effects

Long-term

• Pelvic organ prolapse (post-hysterectomy vaginal vault prolapse)
• Persistent pain (25% of women operated for CPP may have pain persistence or worsening at 1 year)
• Ovarian failure (even if ovaries retained, blood supply may be impaired)

Outcomes

• Prospective studies show that different routes (abdominal vs. vaginal vs. laparoscopic) do NOT significantly differ in long-term urinary or sexual function outcomes at 6 months
• Pain scores and quality-of-life measures are significantly better after laparoscopic vs. open hysterectomy, at 6 weeks and 12 months
• The Maine Women's Health Study found that only 11% of women with frequent pelvic pain reported persistent symptoms after hysterectomy

Preoperative Preparation (Key Considerations)

• Route selection based on anatomy, disease, patient wishes, and surgeon expertise
• Prefer vaginal or laparoscopic over abdominal when feasible (ACOG recommendation)
• Surgeons who cannot perform minimally invasive hysterectomy for benign indications should consider referral
