Ethical Issues in Intrauterine Myelomeningocele Surgery.

Intrauterine surgery shows that the prognosis of neonates with myelomeningocele (MMC) has improved, both in survival and in quality of life. In order to study the current efficacy of intrauterine surgery for MMC and to make an ethical analysis of its proportionality, we conducted a PubMed search using the keywords "myelomeningocele", "intrauterine surgery", "MOMS", and "trial". Thirty-eight articles were found. The literature investigated the risks and benefits of intrauterine surgery based on the physiological parameters of MMC. Intrauterine surgery produces clear benefits. However, it also has disadvantages, such as premature birth, fetal or neonatal death, and uterine complications. The option of surgery is positive. However, since the intervention is risky, the final decision must be prudential, and thus should involve an ethical analysis of therapeutic proportionality. This requires a specific clinical evaluation of the fetus ensuring fetal survival in all cases and minimizing the risks arising from extremely premature birth.
