What is an external fetoscopy?

External fetoscopy is a minimally invasive surgical technique used to visualize and potentially treat a fetus in utero. It involves inserting a fetoscope, a small endoscope with a fiber-optic camera and illumination, through the mother's abdomen and uterine wall to directly observe the fetus and surrounding environment.

Here's an overview of an external fetoscopy procedure:

1. Preparation: The expecting mother is given a local or general anesthetic to ensure comfort and reduce any discomfort during the procedure.

2. Insertion of the fetoscope: A small incision is made in the mother's abdomen, typically near the belly button, to create an entry point. Guided by ultrasound imaging, the fetoscope is inserted through this incision and directed towards the uterus.

3. Observation: Once inside the uterus, the fetoscope provides a clear view of the fetus and its surroundings. The surgeon can examine the fetal anatomy, identify any potential anomalies or conditions, and assess the overall health and well-being of the fetus.

4. Intervention (if necessary): If needed, the surgeon may perform therapeutic interventions during the external fetoscopy. This could involve procedures such as laser surgery to correct certain fetal conditions or administering medications to treat specific health issues.

5. Closure: After the necessary observations and interventions have been made, the fetoscope is carefully withdrawn, and the incision in the mother's abdomen is closed with sutures or surgical glue.

External fetoscopy is typically performed in specialized fetal centers or hospitals equipped with advanced medical technology and experienced medical teams, including maternal-fetal medicine specialists, neonatologists, and pediatric surgeons. It is considered a relatively safe procedure, but like any medical intervention, it does carry some risks and may not be suitable for all pregnancies.
