Cystectomy
In singapore

If you’ve been diagnosed with an ovarian cyst requiring surgical removal, you may be feeling anxious about the procedure ahead. Cystectomy is an operation to remove a cyst from the ovary while keeping as much normal ovarian tissue as possible. It may be recommended for cysts that persist, cause symptoms, look complex on imaging, or raise concerns about complications. Our Gynaecologist in Singapore performs cystectomy using established surgical techniques, focusing on removing the cyst while maintaining ovarian function and fertility potential whenever possible.

What is Cystectomy?

A cystectomy removes cysts from one or both ovaries while preserving the ovary itself. Unlike oophorectomy, which removes the entire ovary, cystectomy removes only the cyst and its capsule, leaving healthy ovarian tissue intact. Preserving the ovary may help maintain hormone production and fertility potential, where clinically appropriate.

Cystectomy may be considered for different benign cyst types, such as:

Functional/physiological cysts that persist,
Dermoid cysts (mature teratomas),
Endometriomas (associated with endometriosis),
Cystadenomas.

Today, many cystectomies are performed laparoscopically (keyhole surgery) through small incisions. Open surgery (laparotomy) may still be needed in some situations.

*Individual results and outcomes may vary. This treatment is administered as part of a comprehensive plan supervised by a healthcare professional.*

May be considered:

Persistent or enlarging ovarian cysts after observation
Cysts causing pain, pressure, bloating, or affecting daily activities
Complex features on ultrasound (e.g., septations or solid areas)
Endometriomas are associated with pain and/or subfertility
Dermoid cysts or other benign tumours requiring removal
Cysts with risk of torsion (twisting)
Cysts that may interfere with fertility plans
Recurrent cysts despite conservative management

May not be suitable (or may require a different approach):

Active pelvic infection not yet treated
Significant medical comorbidities that increase surgical risk
Uncorrected bleeding disorders
Pregnancy (except when surgery is necessary for complications; timing and approach require specialist input)
Imaging or blood test findings suspicious for cancer (these are typically managed by a gynaecologic oncologist with appropriate staging)
Dense adhesions where laparoscopy is unsafe (surgeon may advise open approach)

Our Gynaecologist typically considers imaging findings, blood tests (e.g., tumour markers where indicated), your symptoms, age, fertility goals and overall health before recommending surgery or observation.

*Individual suitability and treatment outcomes may vary. This information is provided for educational purposes and should not replace professional medical consultation.*

Treatment Techniques & Approaches

Laparoscopic (Keyhole) Cystectomy

3–4 small incisions are used to introduce a camera and instruments.
Carbon dioxide gas gently inflates the abdomen for working space.
The cyst wall is carefully separated from healthy ovarian tissue and removed, often in a retrieval bag to reduce spillage.
Many patients mobilise on the same day and go home the same day or after one night, depending on recovery and hospital protocol.

Open Cystectomy (Laparotomy)

A larger incision is used.
Considered for very large/complex cysts, extensive adhesions, or when malignancy is suspected.
Hospital stay and recovery are usually longer than with laparoscopy. *Recovery timelines vary by individual patient factors.*

Robotic-Assisted Cystectomy

Similar to laparoscopy, robotic instruments can aid precision in complex cases.
Our Surgeon can advise if this approach is suitable.

Technology & Equipment Used

Modern cystectomy utilises various technologies. Harmonic scalpels or bipolar energy devices provide tissue dissection with controlled thermal effects to the surrounding ovarian tissue. Specialised retrieval bags aim to prevent cyst spillage during removal, particularly for dermoid cysts or suspected endometriomas. Anti-adhesion barriers may be applied to help reduce post-operative adhesion formation. *The effectiveness of these technologies may vary based on individual patient factors.*

The Treatment Process

Before surgery

Pre-operative assessment: history, examination, ultrasound and relevant blood tests (selected tumour markers may be ordered when indicated).
Pre-op instructions (e.g., fasting) and certain medicines (e.g., blood thinners) may be adjusted.
Anaesthesia review and consent discussion.

During the Procedure

On the day of surgery, you may receive general anaesthesia before the procedure begins. For laparoscopic cystectomy, the abdomen is insufflated with carbon dioxide gas to create working space. The surgeon systematically inspects the pelvis, evaluating both ovaries, fallopian tubes, and surrounding structures.

The affected ovary is mobilised, and the cyst is carefully identified. Using precise dissection techniques, the surgeon separates the cyst capsule from healthy ovarian tissue. The cyst is placed in a retrieval bag before removal to prevent spillage. Meticulous haemostasis aims to minimise blood loss, and the ovary is reconstructed if necessary. The procedure may take varying amounts of time depending on complexity.

After Surgery

Pain and nausea control are provided.
Shoulder tip discomfort from residual gas can occur after laparoscopy and usually improves within 1–2 days.
Early walking is encouraged.
Discharge: the same day or next day for uncomplicated laparoscopy; longer for open surgery or complex cases.

*Timelines vary person-to-person.*

Recovery & Aftercare

First 24-48 Hours	Expect mild–moderate soreness at small incisions (laparoscopy) or more discomfort after open surgery. Take prescribed pain relief; move gently; avoid driving while on strong pain medication. Small amounts of vaginal spotting can occur. Seek urgent care for fever, severe pain, heavy bleeding, persistent vomiting, or redness/pus at wounds.
First Week	Gradually increase walking; avoid strenuous activity and heavy lifting. Keep wounds clean and dry; showering is usually fine unless advised otherwise. Return to desk work may be possible within 1–2 weeks after straightforward laparoscopy (our Gynaecologist may advise based on your role and recovery).
Long-term Recovery	Full recovery after laparoscopy often occurs over several weeks, whereas recovery after open surgery is longer. Resume exercise and sexual activity only after our gynaecologist confirms it is safe. Menstrual changes can occur temporarily. Follow-up to review the histology report and plan ongoing care (e.g., monitoring or medical therapy for endometriosis).

Benefits of Cystectomy

Cystectomy may offer benefits for women with symptomatic or concerning ovarian cysts. Patients may experience reduction of pelvic pain, bloating, and pressure symptoms following cyst removal. The procedure aims to eliminate the risk of cyst-related complications such as rupture, torsion, or haemorrhage, which can cause severe pain and require emergency intervention.

For women concerned about fertility, cystectomy aims to preserve ovarian function by removing only the cyst while maintaining healthy ovarian tissue. This approach can help protect hormone production and egg reserve, particularly important for younger women. Carefully performed cystectomy may help improve fertility outcomes in women attempting conception.

The procedure provides tissue diagnosis through histopathological examination, offering clarity when benign pathology is confirmed. For functional cysts or endometriomas, surgical removal may help reduce the likelihood of recurrent cyst formation when combined with appropriate medical management. The minimally invasive laparoscopic approach may mean faster recovery, less scarring, and quicker return to normal activities compared to open surgery.

Risks & Potential Complications

Most patients recover well, but risks include:

Pain, bruising, or small amount of vaginal bleeding
Infection, bleeding, or blood clots
Injury to nearby organs (e.g., bowel, bladder, blood vessels)
Adhesion formation (may contribute to pain or subfertility)
Reduced ovarian reserve (especially with bilateral surgery or endometrioma excision)
Recurrence of cysts (more likely with certain types, e.g., endometriomas)

Our gynaecologist can discuss how these risks apply to you and the measures taken to reduce them.

Frequently Asked Questions (FAQ)

How long does cystectomy surgery take?

This varies with cyst size, location, adhesions, and whether one or both ovaries are involved. Our Gynaecologist can advise after reviewing your imaging.

Will this affect fertility or hormones?

Cystectomy is to remove the cyst and preserve ovarian tissue where possible. However, surgery, especially for endometriomas or when both ovaries are operated on, can affect ovarian reserve. Our Gynaecologist can discuss fertility considerations and alternatives (including observation or assisted reproduction referrals where relevant).

How soon can I return to work after a laparoscopic cystectomy?

Return to work timing varies following uncomplicated laparoscopic cystectomy. Those with desk-based work may be able to return sooner than those with physically demanding jobs. Recovery varies from person to person, depending on factors such as overall health, cyst complexity, and postoperative healing. Our Gynaecologist can provide personalised return-to-work guidance based on your specific job requirements and recovery progress.

What is the likelihood of cyst recurrence after surgery?

Recurrence risk depends on cyst type. Dermoid cysts rarely recur if completely removed. Endometriomas can recur; medical therapy (e.g., hormonal suppression) may be discussed after surgery to reduce this risk.

Can cystectomy be performed during pregnancy if necessary?

If necessary (e.g., torsion, rupture, or huge cysts), surgery may be considered—often in the second trimester—after specialist assessment and multidisciplinary planning. Laparoscopic surgery can be performed with appropriate modifications.

How do I know if I need a cystectomy versus conservative management?

The decision between surgery and conservative management depends on multiple factors, including cyst size, characteristics on imaging, symptoms, and patient preferences. Larger cysts, those with complex features, symptomatic cysts, or those persisting beyond multiple menstrual cycles may warrant surgical consideration. Our Gynaecologist typically reviews the imaging findings, examines you, and discusses whether watchful waiting or surgical intervention is appropriate for your situation.

Do all cysts need surgery?

No. Many simple cysts resolve with time. Management depends on cyst size/appearance, symptoms, age, and preferences. Your doctor may recommend observation with repeat scans if it is safe to do so.

Conclusion

Cystectomy is one of the options for managing ovarian cysts. Using modern laparoscopic techniques where appropriate, the cyst can be removed while aiming to preserve healthy ovarian tissue and hormonal function. Minimally invasive surgery is generally associated with smaller incisions and may be linked to less discomfort and a quicker return to daily activities than open surgery. Recovery differs for each person; many resume light routines within weeks, depending on the operation and individual factors. Understanding the procedure, recovery, and possible outcomes can help you make an informed decision about your care.
