Dr Ong Xiaohui

Minimally invasive gynaecological surgery

When surgery is recommended, minimally invasive techniques often allow the same procedure to be performed through small incisions or, in some cases, with no abdominal scars at all, as they can be done through the vagina. Dr Ong is experienced in both laparoscopic (keyhole) and hysteroscopic surgery, and will recommend the approach that best fits the condition and your circumstances.

The information here is provided for general knowledge only, and you should arrange a consultation for advice tailored specifically for your condition.

Laparoscopic (keyhole) surgery

Laparoscopy uses small incisions (typically 5–10mm) and a camera to perform surgery inside the abdomen and pelvis. Compared with traditional open surgery, benefits generally include:

  • Smaller incisions — usually 3–4 small cuts instead of one long incision
  • Less post-operative pain
  • Shorter hospital stay — often 1–2 days
  • Faster return to normal activities — typically 1–2 weeks instead of 4–6
  • Smaller scars and a lower risk of wound complications

Laparoscopic procedures

For fibroids

  • Laparoscopic myomectomy (removal of fibroids while preserving the uterus)
  • Laparoscopic hysterectomy where appropriate

For ovarian cysts

  • Laparoscopic cystectomy (removal of the cyst while preserving the ovary)
  • Oophorectomy where indicated, with careful assessment to rule out malignancy first

For endometriosis

  • Laparoscopic excision of endometriotic tissue
  • Endometrioma (endometriotic cyst) removal
  • Adhesion removal

Other procedures

  • Diagnostic laparoscopy for unexplained pelvic pain, infertility, or suspected pelvic conditions
  • Treatment of ectopic pregnancy
  • Tubal procedures

Hysteroscopic surgery

Hysteroscopy uses a thin camera passed through the cervix to look inside the uterus. Because there are no abdominal incisions at all, recovery is usually quicker than with keyhole surgery. It is used both to diagnose and to treat conditions inside the uterine cavity.

Hysteroscopic procedures

  • Removal of endometrial polyps
  • Removal of submucosal fibroids (fibroids within the uterine cavity)
  • Investigation and management of abnormal uterine bleeding
  • Evaluation of recurrent miscarriage or fertility concerns
  • Removal of intrauterine adhesions (Asherman's syndrome)
  • Removal of retained products of conception

What to expect

  • Before surgery — pre-operative assessment, fasting from midnight where required
  • The procedure — performed under general anaesthesia; duration depends on the procedure, from around 20 minutes for a straightforward hysteroscopy to 1–2 hours for more complex laparoscopic work
  • After surgery — recovery in the ward, with most patients discharged within 1–2 days (hysteroscopy may be same-day)
  • At home — light activities for 1–2 weeks, with a follow-up appointment to review your recovery

Is minimally invasive surgery suitable for me?

Most gynaecological conditions can be managed with a minimally invasive approach, but suitability depends on the size and nature of the condition, previous surgeries, and your overall health. In some situations, open surgery remains the safer or more effective option. Dr Ong will explain the pros and cons clearly and recommend what is genuinely best for your treatment and recovery.

Frequently asked questions

Laparoscopic (keyhole) surgery uses small abdominal incisions and a camera to operate inside the abdomen and pelvis. Hysteroscopic surgery passes a thin camera through the cervix to operate inside the uterine cavity, with no abdominal incisions at all. The right approach depends on where the problem is and what needs to be done.
Most patients are discharged within 1 to 2 days. Light activities are usually possible within a few days, with a return to normal activities over 1 to 2 weeks. Heavier lifting and strenuous exercise are typically held back for around 4 weeks. Hysteroscopic procedures often allow same-day discharge and a quicker return to routine.
Laparoscopic surgery uses small incisions, typically 5 to 10mm each, with usually 3 to 4 cuts in total. The scars are small and usually fade significantly over time. They are placed where they are less visible where possible, such as within the umbilicus.
Many large fibroids and advanced endometriosis cases can still be managed laparoscopically, but suitability depends on the size, location, and your individual anatomy. In some situations, open surgery is the safer or more effective choice. Dr Ong will assess your scans and history and discuss the trade-offs honestly.
Most laparoscopic and hysteroscopic procedures are done under general anaesthesia. Anaesthesia is administered by an anaesthetist who reviews your medical history beforehand. Modern anaesthetic techniques are well established for gynaecological procedures, and risks will be discussed with you in the pre-operative consultation.
All surgery carries some risk, including bleeding, infection, injury to nearby organs (such as the bowel, bladder, or blood vessels), reactions to anaesthesia, and the small possibility that a laparoscopic procedure has to be converted to open surgery for safety. The specific risks for your operation will be explained as part of the consent process.
Most laparoscopic procedures involve an overnight stay of 1 to 2 nights. Hysteroscopic procedures are often done as day surgery, with discharge the same day. The exact length of stay depends on the procedure and how you recover.
Many laparoscopic and hysteroscopic procedures are claimable under Medisave, and most major insurers in Singapore cover them. Coverage depends on the procedure code, hospital ward, and your individual policy. The clinic can provide a fee estimate and help with pre-authorisation.
