Resultados materno y perinatal de pacientes con diagnóstico prenatal de gastrosquisis en un centro de Medellín / Maternal and perinatal outcomes of patients with prenatal diagnosis of gastroschisis in a center in Medellin

Objetivo: Describir los resultados maternos y perinatales de pacientes con diagnóstico prenatal de gastrosquisis atendidos en un centro de referencia obstétrica de Medellín. Método: Estudio observacional, descriptivo y retrospectivo, llevado a cabo en la Clínica Universitaria Bolivariana en fetos con diagnóstico prenatal de gastrosquisis desde el 1 de enero de 2010 hasta el 31 de julio de 2021. Resultados: Se identificaron 54 gestantes con diagnóstico prenatal de gastrosquisis. En el 63% era su primer embarazo y el 27,8% eran adolescentes. La duración promedio de la gestación fue de 35 semanas y 6 días. La cesárea fue la vía más común (98,1%) y la indicación más frecuente fue sufrimiento de asa 66,7%. El 55,6% de los neonatos requirieron más de una intervención quirúrgica para el cierre de la pared abdominal. Las complicaciones más frecuentes fueron anemia (66,7%) e íleo posoperatorio (72,2%). La mortalidad fue del 13%. Conclusiones: Se evidencian algunas características similares a las reportadas en otras series. La mayor presentación fue en primer embarazo, la causa de finalización de la gestación fue sufrimiento de asas (demostrando la importancia del seguimiento ecográfico), y las complicaciones más frecuentes fueron anemia e íleo posoperatorio presentados por la prematuridad. La mortalidad comparada con la de otras instituciones locales fue menor.

Objective: To describe the outcomes of maternal and perinatal in patients diagnosed with prenatal gastroschisis that received medical care at an obstetric reference center in Medellin. Method: Observational, descriptive and retrospective study in fetuses with a prenatal diagnosis of gastroschisis performed in the Clínica Universitaria Bolivariana between January 1st 2010 and July 31st 2021. Results: Were included 54 pregnant women with prenatal diagnosis of gastroschisis. The 63% were their first pregnancy and 27,8% were adolescents. The average duration of gestation was 35 weeks and 6 days. Cesarean section was the most common way of delivery (98,1%) and the most frequent indication was suffering from loop (66,7%). The 55,6% of neonates required more than one surgical intervention for closure of the abdominal wall. The most frequent complications were anemia (66,7%) and postoperative ileus (72,2%). A mortality of 13% was presented. Conclusions: Some characteristics like reported in other series are evident. The greatest presentation was in the first pregnancy, the cause of termination of pregnancy was suffering from loops (demonstrating the importance of ultrasound monitoring) and the most frequent complications were anemia and postoperative ileus presented by prematurity. Mortality, compared to other local institutions, was lower.

Novel multidisciplinary approach to monitor and treat fetuses with gastroschisis using the Svetliza Reducibility Index and the EXIT-like procedure / Nova abordagem multidisciplinar para monitorizar e tratar fetos com gastrosquise utilizando o Svetliza Reducibility Index e o procedimento EXIT-like

ABSTRACT Objective: To describe our initial experience with a novel approach to follow-up and treat gastroschisis in "zero minute" using the EXITlike procedure. Methods: Eleven fetuses with prenatal diagnosis of gastroschisis were evaluated. The Svetliza Reductibility Index was used to prospectively evaluate five cases, and six cases were used as historical controls. The Svetliza Reductibility Index consisted in dividing the real abdominal wall defect diameter by the larger intestinal loop to be fitted in such space. The EXIT-like procedure consists in planned cesarean section, fetal analgesia and return of the herniated viscera to the abdominal cavity before the baby can fill the intestines with air. No general anesthesia or uterine relaxation is needed. Exteriorized viscera reduction is performed while umbilical cord circulation is maintained. Results: Four of the five cases were performed with the EXIT-like procedure. Successful complete closure was achieved in three infants. The other cases were planned deliveries at term and treated by construction of a Silo. The average time to return the viscera in EXIT-like Group was 5.0 minutes, and, in all cases, oximetry was maintained within normal ranges. In the perinatal period, there were significant statistical differences in ventilation days required (p = 0.0169), duration of parenteral nutrition (p=0.0104) and duration of enteral feed (p=0.0294). Conclusion: The Svetliza Reductibility Index and EXIT-like procedure could be new options to follow and treat gastroschisis, with significantly improved neonatal outcome in our unit. Further randomized studies are needed to evaluate this novel approach.

RESUMO Objetivo: Descrever a experiência inicial com a nova técnica cirúrgica EXIT-like para acompanhamento e correção de gastrosquise no "minuto zero". Métodos: Foram avaliados onze fetos com diagnóstico pré-natal de gastrosquise. O Svetliza Reducibility Index foi usado prospectivamente para avaliar cinco casos, e seis foram utilizados como controles. O índice foi calculado dividindo-se o diâmetro do defeito da parede abdominal pela maior alça intestinal que coubesse neste espaço. O procedimento EXIT-like compreendeu cesárea programada, analgesia fetal e redução da víscera herniada para a cavidade abdominal, antes da deglutição de ar pelo recém- nascido. Não são necessários anestesia geral e nem relaxamento uterino. A redução da víscera exteriorizada é realizada enquanto se mantém a circulação do cordão umbilical. Resultados: Quatro casos, dos cinco, foram submetidos ao EXIT-like. A correção foi completa em três casos. Os demais casos foram partos a termo planejados, e a correção do defeito foi feita com Silo. O tempo médio de redução da víscera foi de 5,0 minutos no grupo submetido ao procedimento EXITlike, e a oximetria foi mantida dentro dos valores de variação normal em todos os casos. No período perinatal, foram observadas diferenças estatisticamente significativas no tempo de ventilação mecânica (p=0,0169), duração da nutrição parenteral (p = 0,0104) e da nutrição enteral (p=0,0294). Conclusão: O Svetliza Reducibility Index e o procedimento EXIT-like podem ser novas opções para acompanhar e tratar gastroquise, com desfecho neonatal significativamente melhor em nossa unidade. Novos estudos randomizados são necessários para avaliar esta nova abordagem.
