Key Considerations for Medical Students Scrubbing into Hysterectomy and Bilateral Salpingectomy

Medical students should understand that hysterectomy with bilateral salpingectomy is a standard procedure for gynecologic conditions, with total abdominal hysterectomy and bilateral salpingo-oophorectomy being the mainstay of management for conditions like endometrial and ovarian cancer. 1

Surgical Procedure Components

• Standard surgery involves total hysterectomy with bilateral salpingo-oophorectomy (removal of uterus, fallopian tubes, and ovaries) 1
• For benign conditions, the procedure may be a total hysterectomy with bilateral salpingectomy (preserving the ovaries) 1
• The surgical approach may be abdominal, laparoscopic, or vaginal, with each having specific indications and considerations 1, 2
• Bilateral salpingectomy takes approximately 11 minutes of additional operating time with minimal additional blood loss (about 6 mL) 3

Anatomical Considerations

• During the procedure, you should be familiar with key pelvic anatomy including:
  • Uterine blood supply (uterine arteries and veins) 1
  • Ureter location and course (particularly at the pelvic brim and as it passes under the uterine artery) 1
  • Fallopian tubes and their blood supply 1
  • Ovarian ligaments and blood supply if ovaries are being preserved 1

Indications for the Procedure

• Hysterectomy with bilateral salpingectomy may be performed for:
  • Gynecologic malignancies (endometrial, ovarian, or cervical cancer) 1
  • Benign conditions (fibroids, endometriosis, abnormal uterine bleeding) 1
  • Risk-reducing surgery (particularly salpingectomy to reduce ovarian cancer risk) 4, 5

Surgical Approaches

• Abdominal approach: Used for large uteri, suspected malignancy, or when extensive adhesions are expected 1
• Laparoscopic approach: Associated with fewer moderate-to-severe postoperative adverse events and shorter hospital stays compared to open procedures 1
• Vaginal approach: Considered the gold standard for benign pathologies when feasible, with the shortest recovery time 2
• Bilateral salpingectomy is successfully completed in approximately 81% of vaginal hysterectomies, with difficulty more common in patients with prior adnexal surgery or uterine fibroids 3

Perioperative Considerations

• On entering the abdomen, aspiration of ascites or peritoneal lavage may be performed for cytologic examination in cases of suspected malignancy 1
• A maximal effort should be made to remove all gross disease in cancer cases 1
• In benign cases, care should be taken to identify and preserve the ureters and major blood vessels 1
• Prophylactic bilateral salpingectomy does not increase complication rates and may reduce the incidence of adnexal pathologies requiring surgical re-intervention 5

Potential Complications

• Major complications to be aware of include:
  • Bleeding requiring transfusion 4
  • Urinary tract injuries (bladder, ureter) 2
  • Bowel injury 1
  • Infection 4
• Laparoscopic hysterectomy has been associated with a higher rate of bladder and ureteral injuries compared to vaginal hysterectomy in some studies 2

Special Considerations

• In premenopausal women, ovarian preservation may be considered to prevent premature menopause 1, 6
• Women with unilateral oophorectomy should be monitored for signs of premature ovarian failure 6
• Bilateral salpingectomy at the time of hysterectomy has been associated with an increased risk of menopausal symptoms in some studies, even when ovaries are preserved 7
• Hormone replacement therapy should be considered for women experiencing premature menopause due to hysterectomy with oophorectomy 6

Recent Trends

• There has been a significant increase (371%) in the uptake of hysterectomy with bilateral salpingectomy in recent years 4
• This trend is driven by evidence suggesting that many ovarian cancers originate in the fallopian tubes 4
• Prophylactic salpingectomy during hysterectomy is now recommended by professional organizations for ovarian cancer risk reduction 3

Understanding these key aspects will help you participate meaningfully in the procedure and provide optimal care to patients undergoing hysterectomy and bilateral salpingectomy.
