Laparoscopic cervical cerclage

Summary

A laparoscopic cervical cerclage is a keyhole operation to place a permanent supporting stitch at the very top of the cervix, where it joins the womb. It is for women at high risk of late miscarriage or very early birth in whom a vaginal stitch has failed or cannot be placed — for example when the cervix is very short, deeply scarred, or partly removed by previous surgery.

• Ideally placed before pregnancy (an "interval" cerclage); it can also be placed in early pregnancy.
• Done through 3–4 small keyhole cuts under general anaesthetic; usually home the same or next day.
• The stitch sits higher than any vaginal stitch can reach — which is why it can succeed where a vaginal stitch has failed.
• The stitch is permanent: birth must be by planned caesarean, and the stitch can stay in place for future pregnancies.
• For the standard vaginal stitch, see our cervical cerclage guide.

This information supports discussion with your healthcare team. Reading, saving or printing it does not constitute consent to surgery.

About the operation

A vaginal cerclage is placed around the lower part of the cervix. When that part is too short, torn or scarred to hold a stitch, the support must go higher — at the cervico-isthmic junction, where the cervix meets the body of the womb. That level can only be reached from above, through the abdomen, and today this is done by keyhole (laparoscopic) surgery rather than a large open cut.

Through the small cuts, the surgeon opens the tissue over the junction, gently moves the bladder clear, and passes a strong tape around the cervix at its highest point, tying it to hold the cervix closed. The tape is permanent and does not need removal.

Two important consequences follow from where the stitch sits:

• Birth is by planned caesarean — the cervix cannot open for labour with the tape in place.
• The tape can stay for future pregnancies — one operation can protect more than one pregnancy.

In a randomised trial in women with previous failed vaginal stitches (the MAVRIC trial), the abdominal stitch clearly outperformed a repeat vaginal stitch in preventing early birth.

Why it is performed

• A previous vaginal cerclage that failed — a late miscarriage or very early birth despite the stitch
• A cervix that is too short, scarred or torn for a vaginal stitch — after cone biopsy, repeated LLETZ, trachelectomy or birth injury
• Selected women with a strong history of cervical weakness, after specialist assessment

This is specialist surgery for a small group of women; the decision is made with you after reviewing your full obstetric and surgical history.

Benefits

• The best available protection against late miscarriage and very early birth for women in whom vaginal stitches have failed — supported by randomised trial evidence.
• Placed once, protects future pregnancies — the permanent tape does not need repeating.
• Keyhole placement — small cuts, little pain, usually home the next day, and a quick recovery, especially when placed before pregnancy.

Alternatives

• Vaginal cerclage — the standard first-line stitch where the cervix can hold one — see our guide.
• Vaginal progesterone and scan surveillance — for women whose risk profile does not require an abdominal stitch.
• Open (abdominal) cerclage — the same stitch placed through a larger abdominal cut; now uncommon where laparoscopic surgery is available. Not recommended by the author unless it is performed at the same time as another open abdominal surgery.

Preparing for surgery

Timing is the first decision: where possible the stitch is placed before pregnancy, when the womb is small, the view is best and the risks are lowest. When placed during pregnancy, this is usually done late in the first trimester after a scan confirming a normal ongoing pregnancy.

You will have a review of your obstetric history and previous surgery, an ultrasound assessment, blood tests, blood pressure checks and a review of your medicines and general health. Tell the team about all medicines you take — blood thinners may need adjusting — and any previous surgery or anaesthetic problems.

• Smoking: stopping even a few weeks before surgery reduces chest and wound complications.
• Fasting: exact instructions are given; typically no food from 6 hours before, water up to 2 hours before.
• At home: arrange for someone to take you home; plan a quiet week afterwards.

The day of surgery

You are usually admitted on the day of surgery. The team confirms your identity and the planned operation, and you meet the anaesthetist and the surgeon. This is the time for last questions — including how future pregnancies and the caesarean birth will be planned.

You will be asked to sign the consent form, which records the operation, its intended benefits and its risks as they apply to you. You can still change your mind at this point. Compression stockings are usually fitted.

During the operation

The operation is done under general anaesthetic — you are fully asleep and feel nothing. The abdomen is gently inflated with carbon dioxide gas to create working space, and the laparoscope and instruments are introduced through the small cuts.

Working on a magnified view, the surgeon opens the tissue at the top of the cervix, protects the bladder and the blood vessels on each side of the cervix, and passes a strong tape around the cervico-isthmic junction, tying it snugly. In pregnancy the same steps are taken with extra care around the enlarged womb, and the baby is checked before and after. The operation commonly takes about an hour.

After the operation

You will wake in the recovery room. Some shoulder-tip pain is common for a day or two — it comes from the gas used during surgery and settles on its own.

• Pain relief: regular simple painkillers control most discomfort (pregnancy-safe options are used when placed in pregnancy).
• Eating and drinking: usually the same day, starting with fluids.
• Moving: up and about the same day; early walking speeds recovery and protects against clots.
• Going home: usually the same or the following day.

Recovery at home

• Week 1: rest with gentle activity — short walks, light lifting only. Tiredness is normal.
• Week 2 onwards: most women are back to normal activity and routine work.
• Trying to conceive (interval cerclage): usually possible from the next cycle or soon after — confirm the advice in your case.
• In pregnancy: antenatal care continues normally; tell every team who cares for you that an abdominal cerclage is in place.
• Birth: by planned caesarean, usually around 37–39 weeks. The tape is left in place at the caesarean unless you have decided otherwise.

These are typical arrangements; your own advice may differ and comes first.

Risks and complications

The risks below are discussed with you and weighed against the risk the stitch is protecting against. Risks are lowest when the stitch is placed before pregnancy.

Expected, temporary effects

• Pain and tiredness in the first days; shoulder-tip pain from the gas for a day or two
• Bruising around the small cuts; light spotting

Complications

• Bleeding — the tape passes close to the womb's main vessels; significant bleeding is uncommon in experienced hands.
• Injury to the bladder, bowel or ureters — recognised injuries are repaired (rare).
• Infection — of the urine, chest or wounds (uncommon).
• Blood clots in the leg or lung (VTE) — preventive measures are routine (uncommon).
• Conversion to open surgery for safety (uncommon).
• In pregnancy: miscarriage after the procedure — uncommon, and weighed against the risk without the stitch.
• Pregnancy loss with the tape in place — if a pregnancy is lost after the first trimester, the womb cannot empty through the cervix; a surgical procedure (sometimes dividing the tape, or an operation through the womb) is needed. This is discussed fully before consent.
• Ectopic or tape-related problems later — erosion or displacement of the tape over the years (rare).
• Anaesthetic risks — serious anaesthetic complications are rare in otherwise healthy women.

When to seek help

After the operation, seek medical advice the same day if you notice:

• Fever (38 °C or higher) or feeling increasingly unwell
• Worsening abdominal pain not controlled by your painkillers
• A wound that becomes red, swollen, hot or leaks fluid
• Burning on passing urine, or being unable to pass urine
• A painful, swollen or red leg

In pregnancy with the tape in place, come to the hospital without delay if you have contractions or regular tightenings, leaking of fluid, vaginal bleeding, or reduced movements of the baby.

Preparing for your consent discussion

Consent is a conversation, not a signature. Before agreeing you should feel you understand why the abdominal route is recommended for you, its permanence, and what it means for how your babies will be born. The checklist below is a starting point — print it and bring it to your consultation.
