Making a small opening in the uterus (hysterotomy) to repair the spina bifida defect in the fetus (Pruthi et al., 2021).

Benefits: 

• It provides direct access to the fetus, enabling precise closure of the spinal defect, which can reduce the risk of spinal cord damage and associated complications. 

• Additionally, research suggests that this approach may lead to better long-term neurological outcomes compared to repair after birth. 

• Furthermore, by addressing the spinal defect prenatally, there is a potential reduction in the need for ventricular shunting to manage hydrocephalus, a common complication of spina bifida.

Disadvantages: 

• Invasive and carries risks for both the mother and fetus, including premature labor, uterine rupture, and maternal complications such as bleeding and infection.

• The procedure requires specialized expertise and infrastructure, limiting its availability to select medical centers.

• There is a risk of fetal complications such as fetal membrane leakage or injury during the procedure.

Eliminates the necessity for a significant uterine incision, potentially decreasing the overall risks associated with fetal surgery by minimizing uterine trauma and, consequently, lowering the likelihood of preterm labor (VanderWall et al., 1996).

Benefits: 

• Minimally invasive techniques typically result in smaller incisions and less maternal trauma compared to open surgery, potentially reducing the risk of maternal complications such as preterm labor.

• They may offer a shorter recovery time for the mother compared to open fetal surgery.

• Some studies suggest that minimally invasive techniques may still achieve effective closure of the spinal defect while minimizing fetal and maternal risks.

Disadvantages:

• Minimally invasive procedures may be technically challenging and require specialized equipment and expertise.

• They may not be suitable for all cases of spina bifida, particularly those with more severe defects or anatomical complexities.

• The effectiveness and long-term outcomes of minimally invasive techniques compared to open fetal surgery are still being studied, and their benefits may vary depending on individual cases.

These procedures involve accessing the fetus through the mother's abdomen using a needle or catheter. While not as common for spina bifida repair, some minimally invasive techniques for fetal intervention, such as fetal blood or stem cell transfusions, could potentially play a role in treating associated complications or improving outcomes (Kohl, 2014).

Benefits: 

• Less invasive option for fetal intervention, potentially reducing maternal risks such as uterine trauma and preterm labor.

• They may be suitable for certain complications associated with spina bifida, such as fetal blood transfusions to manage anemia.

• These procedures can often be performed under local anesthesia, reducing the need for general anesthesia and its associated risks.

Disadvantages:

• They may have limited applicability to spina bifida repair itself, focusing more on managing associated complications.

• Some percutaneous procedures may still carry risks of fetal injury or complications, particularly if not performed by experienced practitioners.

• Long-term outcomes and effectiveness may vary depending on the specific procedure and indication.
