Evidence - Supracervical hysterectomy, bilateral salpingectomy, laparoscopic

Benign Conditions: Uterine fibroids (~50%), abnormal uterine bleeding (~40%), pain (e.g., in endometriosis/adenomyosis (~30%) or pelvic inflammatory diseases), uterine prolapse (~18%), 

Malignant Conditions: Cervical, endometrial, ovarian cancer, and pre-invasive diseases.

There are conservative and surgical alternatives to hysterectomy, depending on the underlying condition. For example, uterine fibroids can be treated with uterine artery embolization and myomectomy. Pelvic organ prolapse can be managed with conservative therapies such as pelvic floor exercises or pessaries. Chronic pelvic pain can be managed through pain control interventions, including hormonal therapy. Heavy menstrual bleeding can be treated with medical therapies, endometrial ablation, or intrauterine devices. Endometriosis and endometrial hyperplasia can often be treated medically, while cervical intraepithelial neoplasia may be adequately treated by conization.

The choice of surgical approach depends on several factors, including the size and location of the uterus, the need for simultaneous exploration of surrounding pelvic organs, and the patient's medical history.

Before the operation, several questions should be considered: 

1. Can the uterus be retrieved vaginally?
2. Is the indication for surgery (disease) limited to the uterus? Or are other intra-abdominal changes suspected, such as endometriosis, adhesions, changes in the ovaries?
3. Are many intra-abdominal adhesions suspected? 
4. Is a supracervical hysterectomy or a total hysterectomy planned?
5. Are there contraindications for Trendelenburg position or increased intraperitoneal pressure?
6. What is the surgeon's training and experience?

Conditions outside the uterus such as adnexal pathology, severe endometriosis, adhesions, or an enlarged uterus could be contraindications for a vaginal hysterectomy. In these cases, however, another minimally invasive approach may be possible instead of an open abdominal approach. At the beginning of the procedure, a laparoscopic assessment of the pelvis can be performed to evaluate the feasibility of a minimally invasive approach.

The obstetrician-gynecologist should discuss the options with the patients and provide clear recommendations on which type of hysterectomy offers the greatest benefit and minimizes risks given the specific clinical situation.

Between 2008 and 2018, the rates for vaginal hysterectomies decreased from 51 to 13 percent, while the rates for total laparoscopic hysterectomies increased from 12 to 68 percent. Contrary to this trend, evidence supports the view that (when feasible) vaginal hysterectomy is associated with better outcomes and is the most cost-effective method to remove the uterus.

The vaginal hysterectomy: is considered the method with the fastest recovery time and the least postoperative complications.

Laparoscopic (minimally invasive): 

• In a total laparoscopic hysterectomy, the uterus and cervix are removed. 
• In a laparoscopic subtotal (supracervical) hysterectomy, only the uterus is removed. 
• Laparoscopically-assisted vaginal hysterectomy. In laparoscopically-assisted vaginal hysterectomy, a total hysterectomy is performed, with the remainder of the procedure carried out vaginally.
• The robot-assisted surgery offers enhanced precision and flexibility but is costly and requires specialized training.
• V-NOTES combines vaginal access with minimally invasive surgery.

Minimally invasive procedures are less invasive and generally lead to faster recovery and less postoperative pain, shortening hospital stays and postoperative recovery times compared to open abdominal hysterectomy. 

The abdominal hysterectomy is preferred for extensive cases or when the uterus is significantly enlarged, but it results in a longer recovery time and increased postoperative pain.

Minimally invasive approaches to hysterectomy (vaginal or laparoscopic, including robot-assisted laparoscopy) should be performed whenever possible due to their well-documented advantages over abdominal hysterectomy.

Vaginal hysterectomy compared to abdominal hysterectomy:

• Shorter hospital stay, quicker return to normal activity, less pain, no difference in satisfaction, intraoperative injury, or complications.

Vaginal hysterectomy compared to laparoscopic hysterectomy:

• Shorter operation time, lower overall costs, higher patient satisfaction, less frequent vaginal cuff dehiscence, lower risk of urinary tract injury, no differences in return to normal activities or complications, 

Laparoscopic hysterectomy compared to abdominal hysterectomy:

• Faster return to normal activity, shorter hospital stay, fewer wound or abdominal wall infections, longer operation time, higher rate of lower urinary tract injuries, improved postoperative quality of life, no differences in satisfaction or major long-term complications, no differences in overall costs.

Laparoscopic hysterectomy compared to robot-assisted laparoscopic hysterectomy:

• Few differences in measured outcomes

Laparoscopic hysterectomy compared to V-Notes

• less postoperative pain, faster recovery, and improved cosmetic results

Opportunistic salpingectomy, also an oncological prophylactic salpingectomy for ovarian cancer reduction. Approximately 7,000 women are diagnosed with ovarian cancer annually in Germany. In most cases, the cancer is detected at an advanced stage (FIGO III-IV, about 70%), resulting in a poor prognosis. Additionally, there is no good early detection method.

In 2010, the British Columbia Ovarian Cancer Research (OVCARE) team proposed prophylactic salpingectomy as a strategy for primary prevention of ovarian cancer, based on the following observations:

• Carcinogenesis: Most ovarian carcinomas, especially high-grade serous carcinoma, originate from the epithelium of the distal fallopian tube rather than the ovary itself.
• In patients at high risk for ovarian cancer (e.g., patients with BRCA1 and BRCA2 mutations), risk-reducing bilateral salpingo-oophorectomy was performed, where occult tubal carcinomas and/or premalignant lesions were found in the fallopian tube, which were not found in the ovary.
• Premalignant lesions were also found in the fallopian tubes of patients with average risk. Here, salpingectomy was performed for benign reasons, such as sterilization or hysterectomy.
• It was shown that the involvement of the fallopian tubes was present in up to 75 percent of patients diagnosed with ovarian or primary peritoneal serous carcinoma (with and without BRCA mutations), including the presence of fimbrial precancers up to 60 percent.
• Tubal ligation can also reduce the risk of ovarian cancer, with large retrospective studies showing a greater risk reduction for non-serous histologies (particularly endometrioid and clear cell carcinomas).

Mechanisms of risk reduction:

• Removing the initial site of carcinogenesis (high-grade serous carcinomas)
• Removing the tube for the passage of endometriotic or endosalpingiotic cells (clear cell and endometrioid carcinomas)
• Removing the tube for the passage of carcinogens (e.g., talc) or inflammation (e.g., pelvic infection) before reaching the ovary.

The indication for bilateral opportunistic salpingectomy should only be made for patients undergoing pelvic surgery for another reason (e.g., hysterectomy for benign disease, permanent sterilization) and who have completed family planning. In patients at high risk for cancers of the fallopian tube, ovary, and peritoneum (e.g., BRCA gene mutation, Lynch syndrome), a risk-reducing bilateral salpingo-oophorectomy should be performed after a benefit-risk assessment.

Many studies have examined the perioperative course after an opportunistic salpingectomy:

• Extension of surgery time by approximately 10-16 minutes
• Blood loss: no difference
• Hospital stay: no difference
• Perioperative complications (infections, blood draws, rounds, further diagnostics): no difference
• Menopause: Onset of menopause was the same in both groups. However, one study showed that the Anti-Müllerian hormone was slightly lower in the salpingectomy group.

Risk reduction of developing ovarian cancer:

A meta-analysis showed that with a follow-up period of 18-36 years, prophylactic bilateral salpingectomy versus no salpingectomy reduced the risk by almost 50 percent, adjusted for the study population. Overall, the risk of developing ovarian cancer was very low in both groups (0.8 and 0.7 percent, respectively).
