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.

Influence of birthplace on gastroschisis outcomes in a state in the southeastern region of Brazil

Abstract Objective: To characterize the influence of birthplace on outcomes of patients with gastroschisis admitted to three hospitals in a state in Brazil's southeastern region, according to condition inborn (born in a reference center) or outborn (born outside the reference center). Methods: Retrospective multicenter cohort study of patients with gastroschisis. The sample size utilized was of patients admitted in three hospitals with a diagnosis of gastroschisis ICD 10 Q79.3 between January 2000 to December 2018. Patients were divided into two groups, inborn and outborn. Characteristics of prenatal, perinatal and postoperative were compared using statistical tests. The level of significance adopted was P-value < 0.05. Results: In total, 144 cases of gastroschisis were investigated. The outborn patients group had higher rates of absence of antenatal diagnosis (p = 0.001), vaginal delivery (p = 0.001), longer time between birth and abdominal wall closure surgery (p = 0.001), to silo removal (p = 0.001), to first enteral feeding (p = 0.008), for weaning from mechanical ventilation (p = 0.034), used less peripherally inserted central catheter (PICC) and required more venous dissections (p = 0.001), and lower mean of serum sodium (p = 0.015). There were no differences in mortality rates and length of hospital stay between the inborn and outborn groups. Conclusion: Although outborn patients with gastroschisis were less likely to have an antenatal diagnosis and were more prone to a longer time to undergo surgical and feeding procedures, and to spend more time in mechanical ventilation, these disadvantages seemed not to reflect on the death rate and the length of hospital stay of patients from this group.

Eventos adversos associados às doses de fentanil utilizadas nos primeiros dez de vida em neonatos submetidos à correção de gastrosquise / Adverse events associated with doses of fentanyl used in the first ten days of life in neonates undergoing gastroschisis repair

Objetivo: Avaliar a associação entre as doses de fentanil utilizadas nos primeiros dez dias de vida de neonatos submetidos à correção cirúrgica de gastrosquise e as complicações respiratórias e gastrointestinais comumente associadas à essa faixa etária e defeito congênito. Métodos: O presente estudo avaliou de forma retrospectiva a coorte de recém-nascidos portadores de gastrosquise operados no IFF no período de janeiro de 2016 até junho de 2021. Dados demográficos dos neonatos e gestantes, das intervenções cirúrgicas, dos procedimentos anestésicos e dos cuidados perioperatórios em unidade de terapia intensiva neonatal foram coletados de prontuários. Os principais desfechos avaliados foram o tempo de intubação orotraqueal e de ventilação mecânica (IOT/VM), tempo de uso de NPT e data de início de dieta enteral. Foram descritos, tempo para dieta oral plena, tempo de internação em unidade de cuidados intensivos neonatais, diagnóstico de sepse, diagnóstico de apnéia, estridor, pneumonia e taxa de mortalidade. Nos primeiros dez dias de vida dos bebês, as doses de fentanil utilizadas no intraoperatório e periopratório, em bolus ou infusão contínua, foram quantificadas. Assim como, fez-se uma análise descritiva das abordagens cirúrgicas, das técnicas anestésicas e das complicações clínico-cirúrgicas apresentadas durante o período de internação na UTI. Por meio de modelagem estatística, o impacto do aumento das dose de fentanil sobre as complicações respiratórias e gastrointestinais foi avaliado. Resultados: No período do estudo 184 crianças receberam correção cirúrgica do defeito de parede no IFF e a taxa de mortalidade foi de 8,69%. Os dados de 176 neonatos foram coletados e 94% desses pacientes foram indentificadas como gastrosquise simples. Nossa coorte de 144 pacientes foi avaliada e os eventos mais frequentemente relacionados ao uso de maiores doses de fentanil foram aumento do tempo de ventilação mecânica, aumento do tempo total de uso de NPT e retardo para início da dieta enteral. Conclusão: O estudo mostrou piores desfechos respiratórios e gastrointestinais nos pacientes que receberam doses maiores de fentanil.

Objective: To evaluate the association between doses of fentanyl used in the first ten days of life in neonates undergoing surgical correction of gastroschisis and the respiratory and gastrointestinal complications commonly associated with this age group and congenital defect. Methods: This study evaluated retrospectively the cohort of newborns with gastroschisis operated at IFF between January 2016 and June 2021. Demographic data of newborns and pregnant women, surgical interventions, anesthetic procedures and perioperative care in the neonatal intensive care unit were collected from medical records. The main outcomes evaluated were time of orotracheal intubation and time on mechanical ventilation (TI/MV), time of use of PN, time to start enteral nutrition, time to full oral diet, length of stay in the neonatal intensive care unit, sepsis diagnosis, diagnosis of apnea,stridor, pneumonia and mortality rate. In the first ten days of the babies' lives, the doses of fentanyl used in the intraoperative and perioperative, in bolus or continuous infusion, were quantified. As well, a descriptive analysis of surgical approaches, anesthetic techniques and the clinical-surgical complications presented during the ICU stay was made. Through statistical modeling, the impact of increasing fentanyl doses on respiratory and gastrointestinal complications was evaluated. Results: During the study period, 184 children received surgical correction of the wall defect at IFF and the mortality rate was 8.69%. The data from 176 neonates were collected and 94% of these patients were identified as simple gastroschisis. Our cohort of 144 patients was evaluated and the most frequently related events to the use of fentanyl in higher doses were increased time on mechanical ventilation, increased total time of PN use, and delay in starting enteral feeding. Conclusion: The study demontrated worse respiratory and gastrointestinal outcomes in the neonates that received higher doses of fentanyl.

Gastrosquisis: análisis de situación entre los años 2011 y 2016 en el Hospital Pediátrico Pereira Rosell / Gastroschisis: study of the situation in the period between 2011-2016 at the Pereira Rossell Pediatric Hospital / Gastrosquise: análise da situação entre 2011 e 2016 no Hospital Pediátrico Pereira Rosell

La gastrosquisis es el defecto congénito más frecuente de la pared abdominal anterior. Se clasifican en simple o complicadas según si presentan o no anomalías a nivel intestinal. El diagnóstico prenatal se realiza en un 75%-95% de los pacientes. El tratamiento es quirúrgico, lográndose un cierre primario en el 80% de los casos. La mortalidad global reportada a nivel internacional es de un 10%. Se realizó un estudio observacional descriptivo retrospectivo transversal en el que se analizaron los pacientes con gastrosquisis operados en el Hospital Pediátrico del Centro Hospitalario Pereira Rossell entre el primero de enero de 2011 y el 30 de mayo de 2016. Se estudiaron las siguientes variables: incidencia de la patología, edad materna, edad gestacional al diagnóstico y al nacimiento, vía de nacimiento, anomalías asociadas, técnica quirúrgica, incidencia de complicaciones y mortalidad. En el período estudiado se intervinieron 62 pacientes con diagnóstico de gastrosquisis, de los cuales 48 fetos (77,4%) tenían diagnóstico prenatal. El 53,2% nacieron por parto vaginal y 53 % nacieron pretérmino. En el 85,5% se logró realizar un cierre primario. El 69,4% de los neonatos presentaron complicaciones, siendo las infecciosas las más frecuentes. La mortalidad fue de 12,9%, siendo la sepsis la causa más frecuente. Si bien hemos mejorado en el índice de diagnóstico prenatal y en la vía de nacimiento, y las cifras de tratamiento y mortalidad se encuentran dentro de las cifras publicadas a nivel internacional, existe un elevado número de complicaciones infecciosas, que condicionan la evolución y pronóstico de estos pacientes.

Gastroschisis is the most frequent congenital defect of the anterior abdominal wall. They are classified as simple or complicated according to whether or not they present abnormalities at the intestinal level. Prenatal diagnosis is made in 75%-95% of the patients. The treatment is surgical, achieving a primary closure in 80% of cases. The global mortality reported at an international level is 10%. A cross-sectional retrospective observational study was performed in which gastroschisis patients operated at the Pediatric Hospital of the Pereira Rossell Hospital Center between January 1, 2011 and May 30, 2016 were analyzed. The following variables were studied: the pathology, maternal age, gestational age at diagnosis and at birth, birth route, associated anomalies, surgical technique, incidence of complications and mortality. In the period under study, 62 patients diagnosed with gastroschisis were operated on, of which 48 fetuses (77.4%) had a prenatal diagnosis. 53.2% were born by vaginal delivery and 53% were born preterm. In 85.5% a primary closure was achieved. 69.4% of the neonates presented complications, infectious being the most frequent. Mortality was 12.9%, with sepsis being the most frequent cause. Although we have improved in the prenatal diagnosis index and in the route of birth, and the figures of treatment and mortality are among the figures published internationally, there is a high number of infectious complications, which condition the evolution and prognosis of these patients.

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.

Gastroschisis repair under caudal anesthesia: a series of three cases / Correção de gastrosquise sob anestesia caudal: uma série de três casos

Abstract Gastroschisis is a congenital anomaly characterized by a defect in the anterior abdominal wall with protrusion of abdominal viscera. Perioperative mortality is very high in these patients. Traditionally gastroschisis repair has been performed under general anesthesia with endotracheal intubation, requiring postoperative intensive care admission and mechanical ventilation. Caudalblock is an attractive alternative to general anesthesia. We present a series of three neonates with gastroschisis, repaired solely under caudal anesthesia.

Resumo Gastrosquise é uma anomalia congênita caracterizada por um defeito da parede abdominal anterior com protrusão de vísceras abdominais. A mortalidade no período perioperatório é muito elevada nesses pacientes. Tradicionalmente, a correc¸ão de gastrosquise tem sido feita sob anestesia geral com intubac¸ão orotraqueal, o que requer internac¸ão em unidade de terapia intensiva e ventilac¸ão mecânica no pós-operatório. O bloqueio caudal é uma opc¸ão atraente à anestesia geral. Apresentamos uma série de três casos de recém-nascidos com gastrosquise corrigida unicamente sob anestesia caudal.

Nutritional management and postoperative prognosis of newborns submitted to primary surgical repair of gastroschisis / Manejo nutricional e prognóstico pós-operatório do recém-nascido submetido à correção cirúrgica primária de gastrosquise

Abstract Objective Gastroschisis is a defect of the abdominal wall, resulting in congenital evisceration and requiring neonatal intensive care, early surgical correction, and parenteral nutrition. This study evaluated newborns with gastroschisis, seeking to associate nutritional characteristics with time of hospital stay. Methods This was a retrospective cohort study of 49 newborns undergoing primary repair of gastroschisis between January 1995 and December 2010. The newborns’ characteristics were described with emphasis on nutritional aspects, correlating them with length of hospital stay. Results The characteristics that influenced length of hospital stay were: (1) newborn small for gestational age (SGA); (2) use of antibiotics; (3) day of life when enteral feeding was started; (4) day of life when full diet was reached. SGA infants had longer length of hospital stay (24.2%) than other newborns. The length of hospital stay was increased by 2.1% for each additional day taken to introduce enteral feeding. However, slower onset of full enteral feeding acted as a protective factor, decreasing length of stay by 3.6%. The volume of waste drained by the stomach catheter in the 24 h prior the start of enteral feeding was not associated with the timing of diet introduction or length of hospital stay. Conclusion Early start of enteral feeding and small, gradual increase of volume can shorten the use of parenteral nutrition. This management strategy contributes to reduce the incidence of infection and length of hospital stay of newborns with gastroschisis.

Resumo Objetivo A gastrosquise é uma malformação da parede abdominal que resulta em evisceração congênita e requer tratamento intensivo neonatal, correção cirúrgica precoce e nutrição parenteral. Investigaram-se neste estudo os recém-nascidos com gastrosquise e procurou-se correlacionar as suas características nutricionais com o tempo da internação hospitalar. Métodos Estudo de coorte retrospectivo de 49 recém-nascidos submetidos à correção primária de gastrosquise de janeiro de 1995 a dezembro de 2010. As características dos neonatos foram descritas com ênfase nos aspectos nutricionais e relacionadas com o tempo de internação hospitalar. Resultados As características que influenciaram a duração da internação foram: 1) recém-nascidos pequenos para a idade gestacional (PIG); 2) uso de antibióticos; 3) dia de vida ao iniciar a dieta enteral; 4) dia de vida ao atingir a dieta plena. Recém-nascidos PIG tiveram maior tempo de internação (24,2%) do que demais neonatos. O tempo de internação foi aumentado em 2,1% para cada dia a mais que se demorou a introduzir a dieta enteral. Entretanto, atingir mais lentamente o aporte pleno da dieta enteral agiu como fator protetor, diminuiu 3,6% no tempo de internação. O volume de resíduo drenado pelo cateter gástrico, nas últimas 24 horas antes do início da dieta enteral, não apresentou correlação com o momento da introdução da dieta nem com a duração da hospitalização. Conclusão Iniciar a dieta enteral precocemente, com aumento gradativo em pequenos volumes, pode abreviar a duração da nutrição parenteral. Esse manejo contribui para a diminuição da incidência de infecções e do tempo de hospitalização de recém-nascidos com gastrosquise.

Programa de diagnóstico y tratamiento fetal. Estudio de cohorte sobre su efectividad en la evolución de neonatos con patologías quirúrgicas / Program for prenatal diagnosis and treatment: A cohort study on effectivity on the outcome of newborns with surgical pathologies

Introducción. El diagnóstico prenatal de las malformaciones congénitas (MC) permite optimizar el cuidado perinatal. Al Hospital Garrahan (HG) ingresan recién nacidos (RN) con MC para tratamiento quirúrgico. Desde el año 2008 funciona el programa de diagnostico y tratamiento fetal (PDTF) para optimizar el cuidado prenatal y perinatal de RN con MC. El objetivo del estudio es evaluar el impacto de la derivación prenatal en RN que ingresan a la unidad de cuidados intensivos neonatales (UCIN) del HG por MC seleccionadas. Población y Métodos: estudio observacional analítico y comparativo entre grupos, sobre condición de ingreso y evolución de RN con gastrosquisis (GTQ), mielomeningocele (MMC) y hernia diafragmática (HD) y grado de stress parental, según ingreso a UCIN por derivación prenatal o postnatal. Se realizó análisis bivariado, descriptivo y comparativo de indicadores generales y especiales de cuidado. Resultados: Se incluyeron 164 RN (44 con derivación prenatal a través del PDTF). Este grupo presentó: mejor control del embarazo (93% vs 66%, p: 0.04), menor edad gestacional al diagnóstico (24s vs 33s p=0.0006) y mayor tasa de cesárea electiva (95 vs 47%, p=0.0001). Los RN tuvieron menor necesidad de reanimación e ingresaron más tempranamente a la Unidad (mediana 4hs vs 10hs, p=0,004). Hubo menor stress parental en relación al hijo (17 vs 40%). Los RN con GTQ ingresaron mejor curados y se alimentaron por vía enteral más rápidamente. Conclusión: Los RN con MC derivados prenatalmente a través del PDTF, ingresan precozmente y presentaron mejores estrategias de cuidado que los ingresados por derivación habitual (AU)

Introduction. Prenatal diagnosis of congenital malformations (CM) improve perinatal care. At the Garrahan Hospital (GH) newborns (NB) with CM are admitted for surgical treatment. Since 2008 a program for prenatal diagnosis and treatment (PDT) has been in place to optimize prenatal and perinatal care of NB with CM. The aim of this study was to assess the impact of prenatal referral of NB that are admitted to the GH for selected CM. Population and Methods: An observational, analytical, and between-group comparative study was conducted on the status on admission and outcome in NB with gastroschisis (GS), myelomeningocele (MMC), and diaphragmatic hernia (DH) and degree of parental stress, according to NICU admission after prenatal or postnatal referral. Bivariate, descriptive and comparative analysis of general and specific markers of care was performed. Results: 164 NB were included (44 were prenatally referred through the PDT program). The latter group presented with better pregnancy control (93% vs 66%, p: 0.04), younger gestational age at diagnosis (24w vs 33w p=0.0006), and higher rate of elective cesarean section (95 vs 47%, p=0.0001). This group of NB needed less reanimation and were admitted to the NICU earlier (∑4hs vs 10hs, p=0.004). Parental child-related stress was less (17 vs 40%). NB with GS had a better surgical outcome and were started on enteral feeding earlier. Conclusion: NB with CM that were prenatally referred through the PDT program, were admitted earlier and could be managed with better strategies than those who were conventionally referred (AU)

Tratamiento intraparto para la gastrosquisis / Intrapartum treatment for gastroschisis

El tratamiento intraparto de la gastrosquisis es una técnica quirúrgica llevada a cabo durante el nacimiento, bajo el principio de la preservación de la circulación fetoplacentaria, que permite reducir las vísceras herniadas antes de la primera respiración, evita la deglución del aire durante el llanto y minimiza la demora entre el nacimiento y la resolución quirúrgica de esta compleja afección. Se presenta la utilización de esta técnica, por primera vez, en el Centro Territorial de Cirugía Neonatal de Holguín, en un neonato femenino, procedente de la provincia de Santiago de Cuba, nacido por cesárea a las 36 semanas de gestación, e intervenido por un equipo multidisciplinario en la maternidad provincial de Holguín. La corrección del defecto se realizó en los primeros 15 minutos después del nacimiento, antes de cortar el cordón umbilical. La necesidad de apoyo ventilatorio fue menor de 24 horas, y se inició la vía oral en los primeros 3 días después del procedimiento. Al quinto día se observó el cierre total del defecto sin necesidad de suturas. Con la práctica del procedimiento Simil EXIT (similar al extra utero intrapartum treatment de sus siglas en inglés) para gastrosquisis, se logró la corrección inmediata de un defecto complejo de la pared abdominal, que es de alta morbilidad y mortalidad, y permitió la incorporación temprana de la paciente a una vida normal, sin huella quirúrgica y sin complicaciones.

Intrapartum treatment of gastroschisis is a surgical technique applied during birth under the principle of preservation of fetal-placental circulation. It allows reducing herniated viscera before first breathing, prevents air swallowing during crying and minimizes delay between birth and surgical resolution of this complex condition. This report presented the use of this technique for the first time in the territorial center of neonatal surgery in Holguin province. The patient was a female neonate from Santiago de Cuba province, she was born from cesarean section at 36 weeks of gestation and was operated on by a multidisciplinary team in the provincial maternal hospital of the province. The defect was corrected during the first 15 minutes after birth and before cutting the umbilical cord. The ventilation support was necessary for less than 24 hours, and three days after the procedure, the oral route started functioning. On the fifth day, there was observed the total closure of the defect without any suture. With the application of the Simil EXIT procedure (similar to extrauterine intrapartum treatment) for gastroschisis, it was possible to correct immediately the complex defect of the abdominal wall, which is of high mortality and morbidity, and to early incorporate the patient to her normal life with no trace of surgery and no complication.

Fatores associados à mortalidade em recém-nascidos com gastrosquise / Associated factors for perinatal mortality in gastroschisis

OBJETIVO: Analisar a taxa de mortalidade perinatal dos casos de gastrosquise e os possíveis fatores associados. MÉTODOS: Foi realizado estudo de coorte retrospectivo entre 1992 e 2012. Foram incluídos todos os casos de gastrosquise nascidos no Hospital de Clínicas de Porto Alegre (HCPA) naquele período. O diagnóstico de gastrosquise foi obtido por meio do exame ultrassonográfico morfológico ou pelo exame clínico ao nascimento nos casos desconhecidos no pré-natal. As variáveis de nascimento (peso ao nascer, idade gestacional e escore de Apgar, modo de parto, tipo de gastrosquise e anomalias associadas) e cirúrgicas (tipo de fechamento cirúrgico, reintervenção e sepse) foram comparadas entre os casos sobreviventes e os óbitos. Os resultados desta comparação foram analisados de acordo com o tipo de variável por meio de testes paramétricos e não paramétricos (Mann-Whitney ou teste t de Student, χ² ou teste exato de Fisher) sendo considerado o nível de significância de 5% (p=0,05). RESULTADOS: Foram incluídos 64 recém-nascidos com gastrosquise, 59 deles (92,2%) diagnosticados durante o pré-natal. Vinte e seis casos (40,6%) tinham somente intestino exposto, classificados como gastrosquise simples, 22 tinham intestino e estômago (34,4%) e 16 tinham intestino e outros órgãos (25%), totalizando 38 casos de gastrosquise complexa. O reparo cirúrgico primário foi realizado em 44 casos (68,8%). A mortalidade foi de 23,4% (15 mortes). Os casos de óbito tinham peso ao nascer (p=0,001), escore de Apgar (p=0,03) e idade gestacional (p=0,03) significativamente menores que os sobreviventes. Não houve diferença no modo de parto (p=0,8) e, com relação ao conteúdo eviscerado, não houve diferença entre os casos de gastrosquise simples e complexa (p=0,06). A mortalidade foi significativamente mais elevada entre os casos que necessitaram de reintervenção (p=0,001) e com sepse (p=0,008). CONCLUSÃO: A mortalidade perinatal da gastrosquise parece depender principalmente da prematuridade, baixo peso e complicações cirúrgicas.

PURPOSE: To analyze the perinatal mortality rate in cases of gastroschisis and possible associated factors. METHODS: A retrospective cohort study was conducted between 1992 and 2012. All cases of gastroschisis born in Hospital de Clínicas de Porto Alegre (HCPA) during that period were included. The diagnosis of gastroschisis was obtained by morphological ultrasound examination or clinical examination at birth in prenatally unknown cases. The variables of birth (birthweight, gestational age and Apgar score, mode of delivery, type of gastroschisis and associated anomalies) and the surgical ones (type of surgical closure, reintervention and sepsis) were compared between surviving cases and deaths. The results of this comparison were analyzed according to the type of variable using parametric and non-parametric tests (Mann-Whitney or Student's t-test, χ² or Fisher's exact test), with the level of significance set at 5% (p=0.05). RESULTS: Sixty-four newborns with gastroschisis were included, 59 of them (92.2%) diagnosed during the prenatal period. Twenty-six patients (40.6%) had only exposed intestines, classified as simple gastroschisis, 22 had exposure of the intestines and stomach (34.4%) and 16 had exposure of the intestine and other organs (25%), for a total of 38 cases of complex gastroschisis. Primary surgical repair was performed in 44 cases (68.8%). The mortality rate was 23.4% (15 deaths). Babies who died had significantly lower birth weight (p=0.001), gestational age (p=0.03) and Apgar score (p=0.03) than survivors. There was no difference in mode of delivery (p=0.8) and, with respect to gut contents, there was no difference between the cases of simple and complex gastroschisis (p=0.06). Mortality was significantly higher in patients with sepsis (p=0.008) and reintervention (p=0.001). CONCLUSION: in the present study, perinatal mortality due to gastroschisis seemed to depend mainly on prematurity, low birth weight, and surgical complications.

Gastroschisis

We report a case of gastroschisis which was not diagnosed antenatally and was delivered through lower segment caesarean section due to non-reassuring cardiotocograph and small for gestational age fetus in a 21-year old mother. It was associated with oligohydramnios and partial extension of wrist joint in the neonate. After delivery, baby was referred to tertiary care for specialized care by paediatric surgeon and neonatologist where he had silo reduction and surgical repair. Postnatally, the baby is in healthy condition till now

Does administering albumin to postoperative gastroschisis patients improve outcome?

OBJECTIVES: Newborns who undergo surgery for gastroschisis correction may present with oliguria, anasarca, prolonged postoperative ileus, and infection. New postoperative therapeutic procedures were tested with the objective of improving postoperative outcome. PATIENTS AND METHODS: One hundred thirty-six newborns participated in one of two phases. Newborns in the first phase received infusions of large volumes of crystalloid solution and integral enteral formula, and newborns in the second phase received crystalloid solutions in smaller volumes, with albumin solution infusion when necessary and the late introduction of a semi-elemental diet. The studied variables were serum sodium and albumin levels, the need for albumin solution expansion, the occurrence of anasarca, the length of time on parenteral nutrition, the length of time before initiating an enteral diet and reaching a full enteral diet, orotracheal intubation time, length of hospitalization, and survival rates. RESULTS: Serum sodium levels were higher in newborns in the second phase. There was a correlation between low serum sodium levels and orotracheal intubation time; additionally, low serum albumin levels correlated with the length of time before the initiation of an oral diet and the time until a full enteral diet was reached. However, the discharge weights of newborns in the second phase were higher than in the first phase. The other studied variables, including survival rates (83.4 percent and 92.0 percent, respectively), were similar for both phases. CONCLUSIONS: The administration of an albumin solution to newborns in the early postoperative period following gastroschisis repair increased their low serum sodium levels but did not improve the final outcome. The introduction of a semi-elemental diet promoted an increase in body weight at the time of discharge.

Does staged closure have a worse prognosis in gastroschisis?

INTRODUCTION: Correction of gastroschisis can be accomplished by primary or staged closure. There is, however, no consensus regarding the best approach or criteria to favor one method over the other has been established. OBJECTIVE: To compare the outcome of primary and staged closure in newborns with gastroschisis using intravesical pressure (IVP) as the decision criterion. PATIENTS & METHODS: We prospectively analyzed 45 newborns with gastroschisis. An IVP with a threshold of 20 cm H2O was used to indicate primary or staged closure, and the outcomes between the two methods were compared. RESULTS AND DISCUSSION: Newborns in whom primary closure was feasible were born at a lower gestational age. There was no significant difference in the frequency of complications, time to begin oral feeding, length of parenteral nutrition or length of hospital stay. Compared with previous reports, our data showed higher rates of prenatal diagnosis and cesarean delivery, a lower average birth weight, a higher rate of small gestational age babies and a more frequent association with intestinal atresia. Conversely, our data showed a lower rate of postoperative necrotizing enterocolitis and a lower average length of hospital stay. CONCLUSION: No significant difference was observed in the outcome of newborns who underwent primary closure or staged closure of gastroschisis when using an IVP below 20 cm H2O as the criterion for primary closure.

Evolution of critically ill patients with gastroschisis from three tertiary centers

OBJECTIVES AND INTRODUCTION: Gastroschisis is a congenital abdominal wall defect with increasing occurrence worldwide over the past 20-30 years. Our aim was to analyze the morbidity of newborns after gastroschisis closure, with emphasis on metabolic and hydroelectrolyte disturbances in patients at three tertiary university centers. METHODS: From January 2003 to June 2009, the following patient data were collected retrospectively: (A) Background maternal and neonatal data: maternal age, prenatal diagnosis, type of delivery, Apgar scores, birth weight, gestational age and sex; (B) Surgical modalities: primary or staged closure; and (C) Hospital course: levels of serum sodium and levels of serum albumin in the two first postoperative days, number of ventilation days, other postoperative variables and survival. Statistical analyses were used to examine the associations between some variables. RESULTS: 163 newborns were included in the study. Primary closure of the abdominal defect was performed in 111 cases (68.1 percent). The mean serum sodium level was 127.4¡6.7 mEq/L, and the mean serum albumin level was 2.35¡0.5 g/dL. Among the correlations between variables, it was verified that hyponatremia and hypoalbuminemia correlated with the number of days on the ventilator but not with the number of days on total parenteral nutrition (TPN); mortality rate correlated with infection. The final survival rate was 85.9 percent. CONCLUSION: In newborns with gastroschisis, more aggressive attention to hyponatremia and hypoalbuminemia would improve the outcome.

Gastrosquisis: presentación de un caso / Gastroschisis: a case presentation

La gastrosquisis se caracteriza por un defecto de la pared abdominal en el cual los intestinos y otras vísceras se desarrollan fuera del abdomen. Se presenta un caso de un recién nacido de una paciente de 25 años producto de un embarazo de 38.5 semanas, con diagnóstico prenatal tardío de gastrosquisis que se comprueba al nacimiento, se constata salida al exterior de gran parte del intestino delgado, estómago y parte del hígado; a consecuencia de la exposición a que fueron sometidos estos órganos, el estómago presentaba múltiples perforaciones; se interviene quirúrgicamente y se realiza resección amplia de estómago que incluía las perforaciones y se cierra el abdomen, colocándose los órganos expuestos en su interior; evoluciona desfavorablemente y fallece horas después de la intervención.

Gastroschisis is characterized by abdominal wall defect in which intestines and other organs develop outside the abdomen. We report a case of a newborn of a 25 years patient as a result of a 38.5 weeks pregnancy,with delayed prenatal diagnosis of gastroschisis that is checked at birth,there has been found outside most of the small intestine, stomach and part of the liver as a result of the exposure these organs were subjected, the stomach had multiple piercings, and surgical interventions are performed wide resection of the stomach and the abdomen is closed, placing the exposed organs inside; this patient evolves unfavorably and dies hours after surgery.

Tratamiento de los defectos de la pared abdominal (gastrosquisis y onfalocele) en el Hospital Universitario San Vicente de Paúl, Medellín, 1998-2006 / Management of abdominal wall defects (gastroschisis and omphalocele) at Hospital Universitario San Vicente de Paúl, in Medellín, Colombia, 1998-2006

Introducción: la gastrosquisis y el onfalocele son malformaciones de la pared abdominal en neonatos que, a pesar de sus grandes diferencias, tienen en común el hecho de ser enfermedades graves caracterizadas por la herniación de las vísceras intrabdominales a través de un defecto de la pared abdominal. Los niños con estas enfermedades se presentan como emergencias quirúrgicas que plantean un reto difícil para el cirujano tratante. Tienen una tasa de mortalidad que oscila entre 20- 40%, aun con el tratamiento apropiado y se asocian a un amplio rango de malformaciones, principalmente en los niños con onfalocele. Objetivo: el objetivo de la presente revisión retrospectiva es describir el tratamiento de los pacientes con gastrosquisis y onfalocele, y los resultados con él obtenidos, entre 1998 y 2006, en la Sección de Cirugía Pediátrica del Hospital Universitario San Vicente de Paúl (HUSVP), de Medellín. Pacientes y métodos: se evaluaron todos los pacientes que ingresaron al Servicio de Cirugía Pediátrica del HUSVP con diagnóstico de gastrosquisis u onfalocele, entre el 1 de enero de 1998 y el 31 de diciembre de 2006. Se definió el tipo de tratamiento llevado a cabo y, de acuerdo con este, se revisaron los resultados: las complicaciones posquirúrgicas, tales como infección del sitio operatorio, evisceración, sepsis, íleo e hipertensión intrabdominal; el tiempo de inicio de la vía oral y de la nutrición parenteral total (NPT); la permanencia en la unidad de cuidados intensivos (UCI) y la duración de la estancia hospitalaria Resultados: se identificaron 55 pacientes, 32 con gastrosquisis y 23 con onfalocele; en todos se hizo tratamiento quirúrgico. En 31 pacientes (56,4%) se hizo cierre primario y en 24 (43,6%), cierre por etapas; en esta última modalidad el procedimiento más utilizado fue el silo (12 niños; 50%). En 42 pacientes (76,4%) se presentaron complicaciones la más frecuente de las cuales fue la sepsis. La frecuencia de complicaciones asociadas...

Introduction: Gastroschisis and omphalocele are neonatal malformations of the abdominal wall. Despite thei r great di f ferences , both are severe di seases characterized by herniation of viscera through the defect in the abdominal wall. Children with these defects present as surgical emergencies that pose a difficult challenge to the attending surgeon. Even with appropriate management, the mortality rate is between 20-40%.Omphalocele and, to a lesser degree gastroschisis, are associated with a wide range of malformations. Objective: The aim of this retrospective review was to describe the management of children with gastroschisis or omphalocele, and the results obtained with it, at the Pediatric Surgery Section, Hospital Universitario San Vicente de Paúl, in Medellin, Colombia.Patients and methods: We evaluated the charts of all patients admitted to the Pediatric Surgery Section, between January 1, 1998 and December 31, 2006, with a diagnosis of gastroschisis or omphalocele. The type of treatment was defined as either primary closure or closure by stages; accordingly, we reviewed the results of the operation, the surgical complications (surgical site infection, evisceration, sepsis, ileus and intraabdominal hypertension), the time of onset of oral and total parenteral nutrition (TPN), and the duration of hospital and UCI stay Results: 55 patients were identified, 32 with gastroschisis and 23 with omphalocele, all of whom were surgically treated. In 31 patients (56.4%) primary closure was carried out, while in 24 (43.6%) the closure was done by stages; in the latter modality silo was most frequently used (12 cases). Complications, mostly sepsis, occurred in 42 patients (76.4%). The frequency of complications associated...
