Intrauterine surgery--choices and limitations

Area of Science:

• Fetal Medicine
• Surgical Innovation
• Prenatal Diagnosis

Background:

• Significant advancements in intrauterine surgery have occurred over the last decade.
• Randomized trials confirm the benefits of specific intrauterine procedures for fetal well-being.

Purpose of the Study:

• To review the current state and evidence supporting intrauterine surgical interventions.
• To differentiate between established procedures and experimental fetal therapies.

Main Methods:

• A selective literature review was conducted.
• Focus on randomized trials and established outcomes in fetal surgery.

Main Results:

• Fetoscopic laser coagulation for twin-to-twin transfusion syndrome (TTTS) and hysterotomy for spina bifida repair are supported by randomized trials.
• Other fetoscopic procedures show initial promise but lack robust trial data.
• Intrauterine surgery is generally reserved for conditions causing intrauterine death or irreversible damage.

Conclusions:

• Prenatal laser coagulation is indicated for severe TTTS based on strong evidence.
• Evidence for intrauterine surgery for myelomeningocele and congenital diaphragmatic hernia is still insufficient.
• Many intrauterine surgical indications remain experimental, requiring further research and parental counseling.
