- Abstract
Introduction: Large congenital neck tumors can cause neonatal death due to airway obstruction. The aim of this study was to report outcomes of the first cohort of fetuses with neck masses and suspected airway obstruction managed with fetal laryngoscopy (FL) and fetal endoscopic tracheal intubation (FETI) to secure fetal airways and avoid ex utero intrapartum treatment (EXIT) procedure., Methods: A prospective observational cohort of consecutive fetuses with neck masses that were candidates for an EXIT procedure due to suspicion of laryngeal and/or tracheal occlusion on ultrasonographic (US) or magnetic resonance imaging (MRI) examination were recruited for FL in a tertiary referral center in Queretaro, Mexico. FETI was performed if the obstruction was confirmed by FL. Maternal and perinatal outcomes were evaluated., Results: Between January 2012 and March 2023, 35 cases with neck masses were evaluated. Airway obstruction was suspected in 12/35 (34.3%), either by US in 10/35 (28.6%) or by fetal MRI in 2/35 (5.7%). In all cases, FL was successfully performed at the first attempt at a median gestational age (GA) of 36+5 (range, 33+5-39+6) weeks+days, with a median surgical time of 22.5 (12-35) min. In 4 cases, airway patency was confirmed during FL and an EXIT procedure was avoided. In 8/12 cases (66.7%), airway obstruction was confirmed during fetoscopy and FETI was successfully performed at a median GA of 36+3 (33+2-38+5) weeks+days, with a median surgical time of 25.0 (range, 12-45) min. No case required an EXIT procedure. All patients underwent conventional cesarean delivery with no maternal complications and all neonates were admitted to the neonatal intensive care unit with a correctly positioned endotracheal tube (ETT) immediately after delivery. Three neonatal deaths (37.5%) were reported due to postnatal unplanned extubation, failed ETT replacement, and tumoral bleeding., Conclusion: In fetuses with neck masses and suspected airway obstruction, FL and FETI are feasible and could replace EXIT procedures with good maternal and perinatal outcomes., (© 2023 S.

- Abstract
Introduction: A proportion of monochorionic diamniotic (MCDA) twin pregnancies complicated by twin-to-twin transfusion syndrome (TTTS) can present after 26 weeks of gestation. The aim of this study was to compare perinatal outcomes of late TTTS treated by fetoscopic laser coagulation versus traditional management with amniodrainage and/or emergency preterm cesarean delivery (CD)., Methods: Retrospective cohort from January 2012 to January 2023 of consecutive MCDA twin pregnancies complicated by TTTS after 26 weeks and evaluated in our referring centers. We analyzed perinatal outcomes of cases treated with fetoscopic laser surgery at our national referral fetal surgery center in Queretaro, Mexico, and compared them with those managed with traditional management (amniodrainage and/or emergency preterm CD). The primary outcome was survival at discharge and the secondary outcome was gestational age (GA) at birth., Results: Among the study population, 46 TTTS cases were treated by fetoscopy at 27+6 (26+0-31+0) weeks+days and were compared with a group of 39 cases who underwent emergency preterm CD. In comparison to the group who underwent traditional management, the group treated by laser fetoscopy showed a significantly higher GA at birth (32+3 vs. 29+1 weeks+days, p < 0.001), lower frequency of preterm delivery below 37 weeks (91.3% vs. 100%, p = 0.06), 34 weeks (63.0% vs. 100%, p < 0.001), 32 weeks (50% vs. 74.4%, p = 0.02), or 30 weeks (28.3% vs. 53.8%, p = 0.01), and significantly higher perinatal survival (89.1% vs. 71.8%, p < 0.05 of at least one twin; and 65.2% vs. 38.5%, p = 0.01 of both twins, respectively)., Conclusion: MCDA twins complicated with TTTS can be treated with fetoscopic laser surgery between 26 and 31 weeks of gestation, which is a feasible and safe option, and such cases are associated with a higher GA at birth and better perinatal survival than those managed with amniodrainage and/or emergency preterm CD., (© 2023 S.

- Abstract
Congenital oral and neck masses are associated with a high perinatal mortality and morbidity secondary to airway obstruction due to a mass effect of the tumor with subsequent neonatal asphyxia and/or neonatal death. In 1997, the Ex Utero Intrapartum Treatment (EXIT) technique was designed to establish a secure neonatal airway. This procedure allows neonatal tracheal intubation while the uteroplacental circulation maintains fetal oxygenation in a partial fetal delivery during cesarean section. However, it must be emphasized that this technique requires a multidisciplinary team, maternal general anesthesia, high surgery times and potential maternal risks such as placental abruption and increased maternal blood loss due to uterine atony. In addition, the clinical algorithm to obtain a neonatal airway can be quite challenging and neonatal mortality has been reported due to the inability in obtaining an airway at birth. Recently, our Mexican group described a novel minimally invasive fetoscopical technique before cesarean delivery that allows prenatal airway control by means of a fetal endoscopic tracheal intubation (FETI) under maternal peridural anesthesia. This procedure attempted to avoid the need for an EXIT procedure and its potential risks. In this review we described the indications, risks and potential benefits of the EXIT technique and its possible replacement by the fetal endoscopic tracheal intubation technique.
