Ovarian Cyst Surgery

What is Ovarian Cyst Surgery?

Ovarian cyst surgery is a procedure performed to remove a cyst (a fluid-filled sac) from the ovary. While many ovarian cysts are harmless and resolve on their own, some require surgical treatment due to persistent symptoms, large size, risk of rupture or torsion, or concern for malignancy.

The ovaries are two small, almond-shaped organs located on either side of the uterus. They produce eggs and important hormones such as oestrogen and progesterone. A cyst can develop on or within the ovary during the menstrual cycle or as a result of other conditions such as endometriosis, hormonal imbalance, or benign tumours.

In most cases, ovarian cyst surgery is performed using minimally invasive (laparoscopic) techniques. In more complex cases, an open procedure (laparotomy) may be required.

Who is Suitable for Ovarian Cyst Surgery?

Not all ovarian cysts require surgery. Many functional cysts resolve naturally within one or two menstrual cycles. Surgery is usually recommended in specific circumstances.

You may be suitable for ovarian cyst surgery if you:

• Have persistent cysts: That do not resolve after monitoring over several months. 
• Experience significant pelvic pain: Ongoing discomfort, pressure, or pain during intercourse.
• Have a large cyst: Generally larger than 5–7 cm, depending on age and ultrasound features.
• Show suspicious features on ultrasound: Such as solid areas, irregular borders, or increased blood flow.
• Have elevated tumour markers: Such as CA-125 in certain clinical contexts.
• Experience ovarian torsion: A surgical emergency where the ovary twists and cuts off its blood supply.
• Have a ruptured cyst causing internal bleeding: Especially if symptoms are severe.
• Are post-menopausal with an ovarian cyst: As the threshold for surgical management is lower in this group.

Women planning pregnancy may also consider surgery if the cyst interferes with ovulation or fertility treatments.

Benefits of Ovarian Cysts Surgery

Ovarian cyst surgery offers several important benefits when appropriately indicated.

• Pain relief: Removal of the cyst often resolves chronic pelvic pain and pressure symptoms.
• Reduced risk of emergency complications: Surgery can prevent torsion or rupture.
• Improved fertility potential: Particularly if the cyst interferes with ovulation or is associated with endometriosis.
• Definitive diagnosis: The removed tissue is sent to pathology to confirm whether it is benign or malignant.
• Improved quality of life: Relief from bloating, urinary pressure, or discomfort during daily activities.
• Peace of mind: Especially when imaging raises concern about cancer risk.

In most cases, minimally invasive surgery allows for:

• Short hospital stay: Often same-day discharge.
• Faster recovery: Usually 1–2 weeks for laparoscopy.
• Smaller scars: Compared to open surgery.
• Lower risk of complications: Including infection and blood loss.

When performed by an experienced gynaecological surgeon, outcomes are generally very good.

Types of Ovarian Cyst Surgery

The type of surgery depends on the cyst's size, type, and complexity.

Laparoscopic Ovarian Cystectomy

This is the most common approach.

• Minimally invasive procedure: Small incisions in the abdomen.
• Camera-guided removal: The cyst is carefully separated from healthy ovarian tissue.
• Ovary preserved: In most cases, only the cyst is removed.

This approach is ideal for benign-appearing cysts and women wishing to maintain fertility.

Laparoscopic Oophorectomy

In some cases, the entire ovary may need to be removed.

• Used when a cyst replaces most of the ovary: Or if malignancy is suspected.
• Recommended in certain post-menopausal women: Where preserving ovarian function is less critical.

The other ovary typically continues to produce hormones in premenopausal women.

Laparotomy (Open Surgery)

This is a traditional open procedure with a larger abdominal incision. Dr Wong would refer you to a laparotomy specialist for this if required.

• Used for very large cysts: That cannot be safely removed laparoscopically.
• Recommended if cancer is strongly suspected: To allow proper staging and treatment.
• Longer recovery time: Usually 4–6 weeks.

Emergency Surgery

Performed urgently in cases of:

• Ovarian torsion
• Ruptured cyst with heavy internal bleeding

Prompt treatment is critical to prevent loss of ovarian function or life-threatening complications.

Alternative Options to Ovarian Cyst Surgery

Surgery is not always the first step. In many cases, conservative management is appropriate.

Watchful Waiting

• Repeat ultrasounds: To monitor cyst size and appearance.
• Common for functional cysts: Especially in younger women.
• Many resolve naturally: Within 6–12 weeks.

Hormonal Contraception

• Prevents new cyst formation: By suppressing ovulation.
• May help regulate menstrual cycles: In women with recurrent cysts.
• Does not shrink existing large cysts: But can reduce recurrence risk.

Pain Management

• Anti-inflammatory medications: For mild to moderate pain.
• Lifestyle adjustments: Heat packs and activity modification.

Management of Underlying Conditions

• Endometriosis treatment: If cysts are endometriomas.
• Polycystic Ovary Syndrome (PCOS) management: Through hormonal and metabolic treatment.

What to Do Before an Ovarian Cyst Surgery?

Preparation is an important part of ensuring a safe procedure and smooth recovery. Your gynaecologist will provide specific instructions tailored to your individual health needs.

• Attend Pre-operative Consultation: You will review your ultrasound findings, blood tests, and medical history. Tumour markers such as CA-125 may be discussed if relevant. The type of surgery (laparoscopy or open surgery) will be confirmed.
• Discuss Fertility Plans: If you wish to have children in the future, your surgeon will aim to preserve as much healthy ovarian tissue as possible.
• Medication Review: Inform your doctor about all medications and supplements. Blood thinners, aspirin, and certain herbal products may need to be stopped before surgery.
• Fasting Instructions: You will usually need to fast (no food or drink) for 6–8 hours before surgery.
• Smoking and Alcohol: Stopping smoking several weeks before surgery improves healing and reduces complications.
• Arrange Support: Organise transport home and home help for the first few days after surgery.
• Consent and Risk Discussion: Your surgeon will explain the benefits, risks, and alternatives so you can make an informed decision.

Mental preparation is equally important. Most ovarian cyst surgeries are straightforward and performed safely every day. Asking questions beforehand can provide reassurance.

Ovarian Cyst Surgery Procedure

The procedure depends on the cyst's size, type, and complexity.

Anaesthesia

• General Anaesthesia: You will be asleep and pain-free throughout the procedure.

Laparoscopic Ovarian Cystectomy (Most Common)

• Small Incisions: Usually 3–4 small cuts in the abdomen.
• Camera Guidance: A thin camera (laparoscope) is inserted to visualise the ovaries.
• Cyst Removal: The cyst is carefully separated (“shelled out”) from healthy ovarian tissue.
• Preservation of Ovary: In most cases, the ovary remains intact.
• Duration: Typically 45–90 minutes, depending on complexity.

Carbon dioxide is used to gently inflate the abdomen for improved visualisation. This may cause temporary shoulder tip pain after surgery.

Oophorectomy (If Required)

If the cyst has replaced most of the ovary or malignancy is suspected, removal of the ovary may be necessary. The remaining ovary usually continues to produce hormones in premenopausal women.

Laparotomy (Open Surgery)

• Larger Incision: Usually along the lower abdomen.
• Used for Large or Suspicious Cysts: Particularly if cancer is suspected.
• Longer Operating Time and Recovery.

Emergency Surgery

In cases of ovarian torsion or ruptured cyst with internal bleeding, urgent surgery is required to preserve ovarian function and prevent serious complications.

All removed tissue is sent to pathology for examination.

What to Expect After an Ovarian Cyst Surgery?

Recovery varies depending on the surgical approach.

Immediately After Surgery

• Recovery Room Monitoring: Blood pressure, heart rate, and oxygen levels are monitored.
• Mild Nausea or Drowsiness: Common after anaesthesia.
• Pain Management: Pain is usually mild to moderate and controlled with medication.

Most laparoscopic procedures allow same-day discharge or overnight stay.

First Few Days at Home

• Abdominal Discomfort: Mild cramping or bloating is common.
• Shoulder Pain: Due to residual gas from laparoscopy; usually settles within 1–3 days.
• Light Vaginal Spotting: May occur for a few days.
• Fatigue: Rest is important.

Recovery Timeline

• Laparoscopy: Return to light activities within 3–7 days. Full recovery usually within 2 weeks.
• Open Surgery: Recovery may take 4–6 weeks.

You should avoid heavy lifting, strenuous exercise, and intercourse for a few weeks as advised.

Follow-Up Appointment

A follow-up visit is usually scheduled within 1–2 weeks to:

• Review pathology results
• Assess wound healing
• Discuss future fertility or hormonal considerations

Contact your doctor urgently if you experience:

• Fever above 38°C
• Increasing abdominal pain
• Heavy bleeding
• Redness or discharge from the wound
• Persistent nausea or vomiting

Ovarian Cyst Surgery Prognosis

The outlook after ovarian cyst surgery is generally excellent, especially when cysts are benign.

• High Success Rate: Most cysts are completely removed with symptom relief.
• Fertility Preservation: Ovarian function is often maintained when cystectomy is performed.
• Low Recurrence Rate: Though some women may develop new cysts in the future.
• Improved Quality of Life: Relief from pain, bloating, and pressure symptoms.

In cases of endometriosis-related cysts (endometriomas), the risk of recurrence may be slightly higher, and ongoing management may be recommended.

If malignancy is detected (which is uncommon), early diagnosis significantly improves treatment outcomes.

Ovarian Cyst Surgery Risks

While generally safe, all surgery carries some risks.

• Bleeding
• Infection
• Adhesion Formation: Scar tissue may form inside the pelvis.
• Reduced Ovarian Reserve: Particularly if large cysts are removed.

Rare but possible complications:

• Damage to Nearby Organs: Such as bladder, bowel, or blood vessels.
• Removal of ovary
• Anaesthetic Complications
• Conversion to Open Surgery: Occasionally required when laparoscopy is unsafe.

What if Ovarian Cysts Surgery is Delayed?

In selected cases, short-term monitoring is safe. However, delaying necessary surgery may lead to complications.

• Increased Pain: Persistent or worsening symptoms.
• Ovarian Torsion: A surgical emergency that can result in loss of the ovary.
• Cyst Rupture: Causing internal bleeding and acute pain.
• Growth of the Cyst: Making surgery more complex later.
• Missed Early Cancer Diagnosis: Particularly important in post-menopausal women.

Not all cysts require urgent intervention. Many are safely monitored. The decision to proceed with surgery is individualised and based on risk assessment.
