A new hysterotomy closure technique for fetal myelomeningocele repair significantly reduced complications. This modified approach improved hysterotomy healing and decreased obstetric morbidity in cesarean deliveries following prenatal surgery.

Area of Science:

  • Fetal Surgery
  • Maternal-Fetal Medicine
  • Surgical Innovation

Background:

  • Open fetal surgical repair of myelomeningocele is an evolving procedure.
  • Hysterotomy closure is critical for preventing maternal complications during subsequent cesarean deliveries.
  • Standard closure techniques may have associated risks of hysterotomy complications.

Purpose of the Study:

  • To evaluate the efficacy of a modified hysterotomy closure technique in open fetal surgical myelomeningocele repair.
  • To assess the impact of this modification on hysterotomy complication rates at the time of cesarean delivery.

Main Methods:

  • A modified hysterotomy closure technique involving an imbricating serosal-to-serosal layer was applied to all patients undergoing prenatal myelomeningocele repair.

  • Closure utilized interrupted and running #0 polydioxanone (PDS) sutures.
  • Data were collected from operative reports and obstetrician descriptions of hysterotomy healing.

    • Main Results:

    • Of 43 evaluated patients, 95.4% had intact hysterotomy closures.
    • Only one case of partial dehiscence (2.3%) and one thinned scar (2.3%) were observed.
    • No instances of uterine rupture occurred.

    Conclusions:

    • The modified hysterotomy closure technique demonstrated a significantly lower complication rate than anticipated.
    • This simple modification appears to enhance hysterotomy healing.
    • The technique holds potential for reducing obstetric morbidity following fetal surgery for myelomeningocele.
