Introduction: Giant omphalocele (GO) is a complex condition for which many surgical treatments have been developed; however, no consensus on its treatment has been reached. The benefits and efficacy of botulinum toxin A (BTA) in the repair of large abdominal wall defects in adults has been proven, and its reported use in children has recently grown. The goal of this study is to describe a novel technique for primary repair of GO using BTA during the neonatal period and report our initial experience., Methods: patients were followed from August 2020 to July 2022. BTA was applied to the lateral abdominal wall in the first days of life followed by surgical repair of the abdominal defect., Results: while awaiting surgery, patients had minimal manipulation, without requiring mechanical ventilation, were on full enteral feeding, and in contact with their parents. The midline was approximated without tension and without the need for additional techniques or the use of a prosthesis. Patients were discharged with repaired defects., Conclusion: this approach represents a middle ground between staged and the nonoperative delayed repairs. It does not require aggressive interventions early in life, allowing maintenance of mother-child bonding and discharge of the patient with a repaired defect without the need for additional techniques or the use of a prosthesis. We believe that this technique should be considered as a new possible asset when managing this complex condition.

Purpose: To analyze the impact of vaginal delivery after a previous cesarean section on perinatal outcomes., Methods: Case-control study with selection of incident cases and consecutive controls. Maternal and perinatal variables were analyzed. We compared secundiparas who had a vaginal delivery after a previous cesarean delivery (VBAC) (n=375) with secundiparas who had a second cesarean section (CS) (n=375). Inclusion criteria were: secundiparas who underwent a cesarean section in the previous pregnancy; singleton and term pregnancy; fetus in vertex presentation, with no congenital malformation; absence of placenta previa or any kind of bleeding in the third quarter of pregnancy., Results: The rate of vaginal delivery was 45.6%, and 20 (5.3%) women had forceps deliveries. We found a significant association between VBAC and mothers younger than 19 years (p<0.01), Caucasian ethnicity (p<0.05), mean number of prenatal care visits (p<0.001), time of premature rupture of membranes (p<0.01), labor duration shorter than 12 hours (p<0.04), Apgar score lower than seven at 5th minute (p<0.05), fetal birth trauma (p<0.01), and anoxia (p<0.006). In the group of newborns delivered by cesarean section, we found a higher frequency of transient tachypnea (p<0.014), respiratory disorders (p<0.048), and longer time of stay in the neonatal intensive care unit (p<0.016). There was only one case of uterine rupture in the VBAC group. The rate of neonatal mortality was similar in both groups., Conclusions: Vaginal delivery in secundiparas who had previous cesarean sections was associated with a significant increase in neonatal morbidity. Further studies are needed to develop strategies aimed at improving perinatal results and professional guidelines, so that health care professionals will be able to provide their patients with better counseling regarding the choice of the most appropriate route of delivery.
