Fetoscopy facts for kids
Fetoscopy is a special medical procedure. It lets doctors look at and even help a baby while it is still inside its mother's womb. This procedure is only done in special hospitals by expert doctors.
Because fetoscopy is a very tricky procedure, it is usually only done when a baby has serious health problems that need urgent attention before birth.
The biggest risks are that the baby might be born too early (a premature birth) or, in rare cases, a miscarriage might happen. This happens in a small number of cases, about 5 out of 100. In many situations, fetoscopy is used along with, or sometimes replaced by, ultrasound scans.

What is Fetoscopy?
Fetoscopy is a type of surgery that uses a very thin, flexible tube called an endoscope. This tube has a tiny camera and a light at its end. Doctors gently insert this tube through a small cut in the mother's belly and into the womb. This allows them to see the baby and the inside of the womb.
Why Do Doctors Use Fetoscopy?
Doctors use fetoscopy to diagnose and treat certain health problems in unborn babies. It's like having a tiny window into the womb to check on the baby's health.
Diagnosing Problems
Sometimes, doctors need more information than what a regular ultrasound can show. Fetoscopy can help them see things up close, like:
- Checking for problems with the baby's development.
- Looking at the baby's organs, such as the heart or spine.
- Taking tiny samples of tissue or blood from the baby for tests.
Treating Conditions
In some serious cases, fetoscopy can be used to treat conditions before the baby is born. This is called fetal surgery. For example, doctors might use it to:
- Treat problems with blood vessels that connect twins.
- Fix certain birth defects, like spina bifida, while the baby is still in the womb.
- Remove blockages in the baby's urinary system.
How is Fetoscopy Performed?
The procedure usually involves several steps to make sure both the mother and baby are safe.
Before the Procedure
Before fetoscopy, doctors will do many tests, including detailed ultrasound scans. They will explain the procedure to the parents and answer all their questions. The mother might be given medicine to help her relax.
During the Procedure
The mother will usually receive a local anesthetic to numb the area where the tube will be inserted. Sometimes, a general anesthetic is used, meaning the mother will be asleep.
- A very small cut is made in the mother's abdomen.
- The thin endoscope is carefully guided through this cut and into the womb.
- Doctors watch a screen connected to the camera to see inside.
- Tiny instruments can be passed through the endoscope to perform treatments or take samples.
After the Procedure
After the fetoscopy, the mother will be monitored closely. She might need to rest for a few days. Doctors will continue to check on the baby's health with ultrasound scans.
Risks and Safety
Like any medical procedure, fetoscopy has some risks. Doctors only recommend it when the benefits of helping the baby outweigh these risks.
Potential Risks
The main risks include:
- Premature birth: The baby might be born earlier than expected.
- Miscarriage: In a very small number of cases, the pregnancy might end.
- Infection: There's a small chance of infection in the womb.
- Bleeding: Some bleeding can occur at the site of the procedure.
Doctors take every precaution to make the procedure as safe as possible. They use advanced imaging to guide them and work in highly specialized centers.
Alternatives to Fetoscopy
For many conditions, doctors can use less invasive methods to check on a baby's health.
Medical Ultrasound
Ultrasound scans are very common during pregnancy. They use sound waves to create images of the baby. Ultrasounds are safe and can detect many problems. In many cases, a detailed ultrasound can provide enough information, making fetoscopy unnecessary.
Other Tests
Other tests, like Amniocentesis (taking a sample of amniotic fluid) or Chorionic villus sampling (taking a sample from the placenta), can also help diagnose problems. These are often done before considering fetoscopy.
