Introduction

Ovarian torsion is a serious gynecological emergency that occurs when an ovary twists around its supporting ligaments, cutting off its own blood supply. This condition can lead to rapid ovarian ischemia, tissue necrosis, severe pain, and potential loss of ovarian function if not treated promptly. While ovarian preservation is preferred whenever possible, some cases present too late, resulting in irreversible ovarian damage that necessitates oophorectomy.

Laparoscopic oophorectomy has become the preferred surgical approach for managing non-viable ovaries affected by torsion. The minimally invasive technique offers excellent visualization, reduced postoperative pain, faster recovery, and shorter hospital stays compared to traditional open surgery.

Understanding Ovarian Torsion

Ovarian torsion occurs when the ovary rotates around the infundibulopelvic ligament and utero-ovarian ligament, causing obstruction of venous and lymphatic drainage. As swelling progresses, arterial blood flow becomes compromised, resulting in ischemia and eventual necrosis.

Common Risk Factors

• Ovarian cysts or masses larger than 5 cm
• Benign ovarian tumors
• Pregnancy
• Ovulation induction treatments
• Polycystic ovaries
• Previous episodes of torsion
• Elongated ovarian ligaments

The condition can occur at any age but is most commonly seen in women of reproductive age.

Clinical Presentation

Patients with ovarian torsion often present with:

• Sudden onset severe lower abdominal or pelvic pain
• Nausea and vomiting
• Pelvic tenderness
• Adnexal mass on examination
• Intermittent pain episodes due to partial torsion
• Low-grade fever in advanced cases

The symptoms frequently mimic appendicitis, ectopic pregnancy, or renal colic, making prompt diagnosis challenging.

Diagnostic Evaluation

Ultrasound Examination

Transvaginal ultrasonography with Doppler flow studies is the primary imaging modality.

Typical findings include:

• Enlarged edematous ovary
• Peripheral displacement of follicles
• Reduced or absent blood flow
• Twisted vascular pedicle ("whirlpool sign")
• Associated ovarian cyst or mass

Additional Investigations

• Complete blood count
• Pregnancy testing
• Pelvic MRI in selected cases
• CT scan when diagnosis remains uncertain

Despite advanced imaging, definitive diagnosis is often established during surgery.

Indications for Laparoscopic Oophorectomy

Although detorsion and ovarian conservation are attempted whenever feasible, laparoscopic oophorectomy becomes necessary when:

• The ovary is gangrenous or necrotic
• No viable ovarian tissue remains
• Suspicion of malignancy exists
• Severe hemorrhagic infarction is present
• Recurrent torsion occurs in a non-functional ovary
• Extensive tissue destruction prevents preservation

The decision is made intraoperatively based on ovarian appearance and viability assessment.

Preoperative Preparation

Patients undergo:

• Detailed history and physical examination
• Laboratory investigations
• Imaging studies
• Informed consent explaining possible ovarian removal
• Intravenous fluid resuscitation
• Pain management
• Prophylactic antibiotics

Given the emergency nature of ovarian torsion, surgery should not be unnecessarily delayed.

Surgical Technique of Laparoscopic Oophorectomy

Patient Positioning

The patient is placed in the dorsal lithotomy position under general anesthesia.

Port Placement

Typically, three or four laparoscopic ports are inserted:

• Umbilical camera port
• Two lateral working ports
• Additional accessory port if required

Initial Exploration

A systematic inspection of the pelvis identifies:

• Twisted adnexa
• Ovarian enlargement
• Degree of ischemia
• Associated cysts or masses
• Contralateral ovary status

Assessment of Viability

The surgeon carefully evaluates ovarian color, perfusion, and tissue integrity.

Signs of non-viability include:

• Black or dark blue discoloration
• Absence of reperfusion after detorsion
• Tissue necrosis
• Structural collapse

Oophorectomy Procedure

The procedure involves:

1. Identification of the infundibulopelvic ligament.
2. Sealing and division of ovarian blood vessels using advanced energy devices.
3. Transection of the utero-ovarian ligament.
4. Complete removal of the affected ovary.
5. Placement of the specimen into an endoscopic retrieval bag.
6. Extraction through a trocar site.

Final Inspection

The surgical field is inspected for:

• Hemostasis
• Injury to adjacent structures
• Pelvic contamination
• Adequate removal of diseased tissue

Ports are removed and incisions closed.

Advantages of the Laparoscopic Approach

Compared with laparotomy, laparoscopic oophorectomy offers numerous benefits:

Minimal Surgical Trauma

Small incisions reduce tissue damage and postoperative discomfort.

Faster Recovery

Most patients resume normal activities within one to two weeks.

Reduced Hospital Stay

Many patients are discharged within 24 hours.

Superior Visualization

Magnified imaging allows precise identification of anatomical structures.

Lower Risk of Adhesions

Reduced tissue handling minimizes postoperative pelvic adhesions.

Better Cosmetic Results

Small scars provide excellent aesthetic outcomes.

Postoperative Care

Following surgery, patients receive:

• Pain control medications
• Early mobilization
• Dietary advancement as tolerated
• Monitoring for complications
• Follow-up evaluation

Patients are encouraged to gradually resume routine activities according to recovery progress.

Potential Complications

Although uncommon, complications may include:

• Bleeding
• Infection
• Injury to bowel, bladder, or ureter
• Port-site hernia
• Venous thromboembolism
• Adhesion formation

Experienced laparoscopic surgeons significantly reduce these risks.

Fertility Considerations

Removal of one ovary generally does not prevent future pregnancy. The remaining ovary continues to:

• Produce eggs
• Maintain hormonal function
• Support natural conception

Counseling regarding fertility and reproductive planning remains an important component of postoperative care, particularly in younger women.

Outcomes and Prognosis

When performed promptly, laparoscopic management of ovarian torsion provides excellent outcomes. Patients benefit from:

• Rapid symptom relief
• Minimal postoperative pain
• Early return to normal activities
• Low complication rates
• Preservation of overall reproductive potential when the opposite ovary is healthy

The key determinant of ovarian preservation remains early diagnosis and immediate surgical intervention.

Conclusion

Laparoscopic oophorectomy represents a safe, effective, and minimally invasive treatment for ovarian torsion when the ovary has become non-viable. The procedure combines the advantages of advanced laparoscopic surgery with excellent clinical outcomes, enabling rapid recovery and reduced surgical morbidity. Early recognition of ovarian torsion and timely intervention remain critical for optimizing patient outcomes and preserving reproductive health whenever possible.
