Application of pressure-controlled ventilation-volume guaranteed ventilation mode in neonatal thora-coscopic esophageal atresia surgery / 临床麻醉学杂志

Objective To investigate the ventilation effect and application safety of pressure-con-trolled ventilation-volume guaranteed(PCV-VG)mode in neonatal thoracoscopic esophageal atresia surgery.Methods Thirty-six newborns who underwent thoracoscopic esophageal atresia surgery under general anes-thesia,22 males and 14 females,aged 1-4 days,weighing 1.4-4.5 kg,ASA physical status Ⅲ or Ⅳ,were divided into two groups using a random number table method:the PCV-VG mode group(group P)and the volume-controlled ventilation(VCV)mode group(group V),18 newborns in each group.After anes-thesia,PCV-VG and VCV ventilation modes were employed for mechanical ventilation in groups P and V,respectively.The MAP,HR,and SpO2 were recorded prior to tracheal intubation,10 minutes before one-lung ventilation(OLV),30 minutes after OLV,and 10 minutes after completion of OLV.Additionally,the Pmean,Ppeak,Pplat,Cdyn,PETCO2,PaCO2,PaO2,and pH were monitored 10 minutes before OLV,30 minutes after OLV,and 10 minutes after completion of OLV.The time of tracheal tube removal after surgery and the duration of ICU retention were also observed.Results Compared with group V,the SpO2,Cdyn,PaO2,and pH levels showed a significant increase,while significant decrease were noted in Pmean,Ppeak,and Pplat in group P 30 minutes after OLV(P＜0.05).Compared with group V,the PETCO2 and PaCO2 in group P decreased significantly 30 minutes after OLV and 10 minutes after completion of OLV.Be-sides,compared with group V,the time of tracheal tube removal after surgery and the duration of ICU reten-tion were also significantly shortened in group P(P＜0.05).Conclusion The utilization of PCV-VG ven-tilation mode in neonatal thoracoscopic esophageal atresia surgery,as compared to VCV ventilation mode,can effectively reduce airway pressure,enhance lung compliance,optimize intraoperative lung gas exchange,and facilitate postoperative recovery of the neonates.

Congenital esophageal atresia:clinical report of 553 cases / 中国新生儿科杂志

Objective:To study the clinical characteristics of congenital esophageal atresia (CEA) and risk factors of mortality associated with esophageal repair (ER) surgery.Methods:From January 2010 to December 2022, patients diagnosed of CEA using chest and abdomen X-ray and esophagography in our hospital were retrospectively reviewed. The patients were assigned into ER group and non-ER group according to the treatments. The ER group was subgrouped into survival group and death group according to the prognosis. Clinical data and outcomes were collected and compared between the groups.Results:A total of 553 cases were enrolled. According to Gross classification, 29 patients (5.2%) were type A, 2 patients (0.4%) were type B, 504 patients (91.1%) were type C, 6 patients (1.1%) were type D and 11 patients (2.0%) were type E. One patient had simple transluminal septal atresia of the esophagus. 406 patients were in ER group and 147 in non-ER group. Compared with ER group, non-ER group had significantly higher incidences of preterm birth, low birth weight and overall malformations (all P<0.05). In ER group, 152 patients (37.4%) received open thoracic surgery (OTS), 243 (59.9%) had video-assisted thoracoscopic surgery (VATS) and 11 (2.7%) were VATS converted to OTS. Postoperative anastomotic leakage (PAL) occurred in 92 patients (22.7%) and 15 patients (3.7%) died after surgery. The median length of hospital stay was 23 (17, 36) d. Compared with the survival group, the death group had higher incidences of preterm birth, low birth weight, VATS converted to OTS, mechanical ventilation after ER, and shorter length of hospital stay (all P<0.05). After adjusted for birth weight, VATS converted to OTS ( OR=9.585, 95% CI 1.899-48.374) and mechanical ventilation after ER ( OR=7.821, 95% CI 1.002-61.057) were risk factors of mortality in ER patients. Conclusions:Non-ER patients have higher incidences of preterm birth, low birth weight and overall malformations than ER patients. VATS is the method of choice for CEA. Preterm birth, low birth weight, VATS converted to OTS and mechanical ventilation after ER are risk factors of mortality in ER patients.

Esophageal replacement in children - 27 years of experience in a University Hospital / Substituição esofágica em crianças - 27 anos de experiência em um Hospital Universitário

ABSTRACT Introduction: esophageal replacement in children is indicated when it is impossible to maintain the native esophagus, which in the pediatric population includes patients with esophageal atresia and esophageal caustic stenosis. The objective of this communication is to report the experience of a university service with two techniques of esophageal replacement. Methods: this is a retrospective study based on the revision of hospital files. The study population consisted of patients who underwent esophageal replacement from 1995 to 2022, at the Hospital de Clínicas of the State University of Campinas. The analyzed data were age, sex, underlying disease, technical aspects, complications, and long-term results. Results: during the study period, 30 patients underwent esophageal replacement. The most common underlying diseases were esophageal atresia (73.33%) and caustic stenosis (26.67%). Twenty-one patients underwent gastric transposition (70%), and nine underwent esophagocoloplasty (30%). The most frequent postoperative complication was fistula of the proximal anastomosis, which occurred in 14 patients. Most of the patients with fistulas had a spontaneous recovery. There were three deaths. Of the 27 survivors, 24 can feed exclusively by mouth. Conclusion: esophageal replacement in children is a procedure with high morbidity and mortality. Esophagocoloplasty and gastric transposition have similar results and complications, with the exception of proximal anastomotic fistulas, which are generally self-resolving and are more common in esophagocoloplasty. The choice of the best surgical technique must be individualized according to the patients characteristics and the surgeons experience, as both techniques offer the ability to feed orally in the short or medium term.

RESUMO Introdução: a substituição esofágica em crianças está indicada quando não é possível manter o esôfago nativo, o que inclui principalmente pacientes com atresia esofágica e estenose cáustica esofágica. O objetivo deste trabalho é relatar a experiência de um serviço universitário com duas técnicas de substituição esofágica, a transposição gástrica e a esofagocoloplastia. Métodos: Estudo retrospectivo baseado na revisão de arquivos hospitalares. A população do estudo foi de 30 pacientes com idade entre 6 meses e quatorze anos, submetidos à substituição esofágica, no período de 1995 a 2022, no Hospital de Clínicas da Universidade Estadual de Campinas. Os dados analisados foram idade, sexo, doença de base, aspectos técnicos, complicações e resultados a longo prazo. Resultados: As doenças de base mais comuns foram atresia de esôfago (73,33%) e estenose cáustica (26,67%). Vinte e um pacientes foram submetidos à transposição gástrica (70%) e nove à esofagocoloplastia (30%). A complicação pós-operatória mais frequente foi fístula da anastomose proximal, que ocorreu em 14 pacientes. A maioria dos pacientes com fístula teve recuperação espontânea. Houve três mortes no total. Dos 27 sobreviventes, 24 conseguem se alimentar exclusivamente por via oral. Conclusão: A substituição esofágica em crianças é um procedimento com alta morbimortalidade. Esofagocoloplastia e transposição gástrica têm resultados e complicações semelhantes, com exceção de fístulas da anastomose proximal, que são em geral auto-resolutivas e mais comuns na esofagocoloplastia. A escolha da melhor técnica cirúrgica deve ser individualizada, sendo que ambas as técnicas oferecem a capacidade de alimentação via oral a curto ou médio prazo.

Clinical features of five cases of congenital esophageal atresia complicated with gastric perforation / 中国小儿急救医学

Objective:To investigate the clinical characteristics of congenital esophageal atresia with gastric perforation, and to improve pediatricians′ understanding of this disease.Methods:The clinical data of five neonates with congenital esophageal atresia and gastric perforation treated in the neonatal intensive care unit of the Affiliated Hospital of Qingdao University from 2012 to 2022 were analyzed retrospectively.Results:Among the five neonates, four were boys and one was girl.The gestational age was 28 + 5 to 37 + 6 weeks, the birth weight was 1 100~2 350 g. All of them had dyspnea and feeding difficulties after birth.Gastric perforation occurred in three cases during invasive mechanical ventilation, one case during non-invasive ventilation, and one case during nasal catheter oxygen inhalation.Emergency primary gastric repair was performed, followed by secondary esophageal anastomosis.All the patients were cured and discharged from hospital. Conclusion:Gastric perforation is a rare complication of congenital esophageal atresia, which is more common in premature infants and low birth weight infants.Mechanical ventilation may promote the occurrence of gastric perforation.If gastric perforation is complicated, repair should be performed as soon as possible, and esophageal anastomosis surgery should be performed early after stability to improve the final outcome.

Comparación de vía mediastinal posterior versus vía retroesternal para el reemplazo de esófago con ascenso gástrico parcial. Motivo de un cambio de estrategia / Comparison of posterior mediastinal versus retrosternal route for esophageal replacement with partial gastric pull-up. Rationale for a change in strategy

Introducción: existen dos rutas para realizar el reemplazo de esófago (RE), la retroesternal (RRE) y la mediastinal posterior (RMP). El objetivo del estudio es comparar los pacientes que recibieron un ascenso gástrico parcial empleando estas dos rutas. Material y métodos: Se revisaron las historias clínicas de 51 pacientes con ascenso gástrico parcial, en 27 años en el Hospital Garrahan. Se utilizó la vía RRE en 25 casos y la RMP en 26. Fueron comparados los datos epidemiológicos de los grupos y las variables para valorar la dificultad del acto quirúrgico, evolución inmediata y alejada. El estudio es comparativo, retro-prospectivo y longitudinal. Resultados: las características generales de los pacientes fueron similares. Los que recibieron el ascenso gástrico por vía RMP presentaron una menor incidencia de dehiscencia (p=0,017), de enfermedad por reflujo gastroesofágico (ERGE) (p=0,001) y de dumping (p=0,0001). No hubo diferencias estadísticamente significativas entre los dos grupos al comparar la duración del procedimiento, días de internación total y en Unidad de Cuidados Intensivos (UCI), días de permanencia en asistencia respiratoria mecánica (ARM), inicio de alimentación oral y estenosis de la anastomosis. Se observó una tendencia clínicamente relevante, que no alcanzó significancia estadística en las complicaciones intraquirúrgicas y número de dilataciones postoperatorias. No hubo necrosis del ascenso. Fallecieron 2 pacientes. Conclusiones: considerando la menor incidencia de dehiscencia, ERGE y dumping reemplazados por RMP, elegimos a ésta como nuestra primera opción para el reemplazo esofágico en la infancia (AU)

Introduction: The two routes for esophageal replacement (ER) are retrosternal (RRE) and posterior mediastinal (PMR). The aim of the study was to compare patients who received a partial gastric pull-up using either of these two routes. Material and methods: The clinical records of 51 patients who underwent partial gastric pull-up over 27 years at the Garrahan Hospital were reviewed. The RRE route was used in 25 and the RMP in 26 cases. The epidemiological data of the groups and the variables to evaluate the complexity of the surgical procedure, and shortand long-term outcome were compared. A comparative, retroprospective, and longitudinal study was conducted. Results: the general characteristics of the patients were similar. Those who underwent gastric pull-up via PMR had a lower incidence of dehiscence (p=0.017), gastroesophageal reflux disease (GERD) (p=0.001), and dumping (p=0.0001). No statistically significant differences were found between the two groups when comparing the duration of the procedure, days of total hospital and intensive care unit (ICU) stay, days on mechanical ventilation (MV), initiation of oral feeding and stenosis of the anastomosis. A clinically relevant trend, which did not reach statistical significance, was observed in intraoperative complications and number of postoperative dilatations. There was no necrosis of the pull-up. Two patients died. Conclusions: considering the lower incidence of dehiscence, GERD, and dumping associated with PMR, this was our first choice for esophageal replacement in infancy (AU)

Advances in diagnosis and treatment of H-type tracheoesophageal fistula / 中华实用儿科临床杂志

Congenital H-type tracheoesophageal fistula (H-TEF) is a rare type of esophageal atresia.With the continuous development of ultrasound and magnetic resonance imaging (MRI) in the field of prenatal diagnosis in recent years, thoracoscopic surgery and endoscopic treatment, which are more minimally invasive than traditional open surgery, have also been carried out.Based on previous research reports, the diagnosis and treatment of congenital H-TEF was reviewed in this paper.

Congenital esophageal atresia with or without tracheoesophageal fistula is a relatively common and serious congenital gastrointestinal anomaly, which can be surgically repaired to achieve long-term survival in the majority of patients.However, various consequent long-term complications would affect the physical and mental health of patients, thus inducing a decline in their quality of life.In this study, the present status and advances of diagnosis and treatment of these complications were reviewed, in an attempt to further explore the long-term complications after congenital esophageal atresia.

CHARGE syndrome in a neonate with esophageal atresia / 中华围产医学杂志

This article reported a case of neonatal CHARGE syndrome complicated by congenital esophageal atresia. A prenatal ultrasound examination at 30 weeks of gestation revealed polyhydramnios and a small magenblase of the fetus, then fetal MRI suggested congenital esophageal atresia. The infant was born with severe asphyxia at 37 +5 gestational weeks by cesarean section due to placental abruption with a birth weight of 2 310 g. Gastric tube could not be placed after resuscitation. Congenital esophageal atresia complicated by tracheoesophageal fistula was diagnosed by esophageal imaging. Bilateral choanal atresia was detected by electronic nasopharyngoscopy and MRI. Moreover, skull defect, suspected meningocele were also observed. CHARGE syndrome was confirmed by whole exome sequencing, revealing a frameshift deletion of c.2155delA (p.Thr719GlnfsTer9) in the CHD7 gene. The infant died after withdrawing treatment.

Introdução: As malformações congênitas são defeitos que ocorrem durante o desenvolvimento embrio-fetal, principalmente entre a terceira e oitava semana de gestação, podendo ser suspeitado no período pré-natal. A atresia de esôfago com ou sem fístula traqueoesofágica pode estar associada a outras anomalias congênitas, como o ânus imperfurado, o qual faz parte uma síndrome denominada malformação anorretal. Objetivo: discutir o caso de um recém-nascido (RN) portador de atresia de esôfago tipo III e ânus imperfurado, bem como associar suas ocorrências simultâneas. Relato de caso: paciente do sexo masculino, advindo de uma gestação gemelar complicada por pré-eclâmpsia, apresentava ao nascimento ausência do reflexo de busca e sucção, bradicardia e cianose central. Foi diagnosticado com ânus imperfurado e atresia esofágica. Foram realizados cirurgia de Colostomia em Duas Bocas e tratamento cirúrgico da atresia de esôfago. O paciente ficou 48 dias em incubadora com intubação orotraqueal e ventilação mecânica por 26 dias. Resultado: a programação pós- alta indicada foi o acompanhamento com cirurgião pediátrico e neurocirurgião, tendo evoluído bem e aguardando anorretoplastia. Conclusão: o rápido diagnóstico é tão necessário, nesses casos, quanto as abordagens cirúrgicas. O apoio psicológico aos familiares é de extrema importância, pois visa a melhor aceitação da família frente ao caso, propiciando dessa forma, melhores prognóstico e tratamento do paciente.

Introduction: Congenital malformations are defects that occur during embryo-fetal development, especially between the third and eighth week of pregnancy, and may be suspected in the prenatal period. Esophageal atresia with or without tracheoesophageal fistula may be associated with other congenital anomalies, such as the imperforate anus, which is part of a syndrome called anorectal malformation. Objective: to discuss the case of a newborn (NB) with type III esophageal atresia and imperforate anus, as well as to associate its simultaneous occurrences. Case report: male patient, resulting from a twin pregnancy complicated by pre-eclampsia, had at birth the absence of the search and suction reflex, bradycardia and central cyanosis. He was diagnosed with imperforate anus and esophageal atresia. Double-barrel colostomy surgery and esophageal atresia surgery were performed. The patient spent 48 days in an incubator with orotracheal intubation and mechanical ventilation for 26 days. Results: the post-discharge schedule indicated was for follow-up with a pediatric surgeon and neurosurgeon. Patient evolved well and awaits anorectomy. Conclusion: rapid diagnosis is as necessary in these cases as surgical approaches. Psychological support to family members is extremely important, as it aims at better family acceptance in the case, thus providing better prognosis and treatment for the patient.

Objective. To describe the epidemiological characteristics, hospital follow-up, and course of patients who underwent surgery for esophageal atresia and its consequences on lung function. Population and methods. Retrospective, longitudinal, and analytical study. The medical records of patients with esophageal atresia born between 1996 and 2017 were reviewed. Perinatal data, type of atresia, associated malformations, respiratory and gastrointestinal complications, and spirometry data were recorded over 3 years. Results. A total of 97 patients were included. The most common type of atresia was III, and the most frequent syndrome, trisomy 21; 13.4 % of patients died in the neonatal period; 23.8 % were followed up by the Department of Pulmonology, and their respiratory complications included exacerbations (46.4 %), wheezing or asthma (36 %), and pneumonia (26.8 %). Gastroesophageal reflux was a risk factor for wheezing (OR: 5.31; p = 0.002), exacerbations (OR: 4.00; p = 0.009), and pneumonia (OR: 3.24; p = 0.02). In the first spirometry (n = 20), the pattern was normal in 65 %; restrictive in 30 %; and mixed in 5 %. In the second spirometry (n = 19), the pattern was normal in 42.1 %; restrictive in 31.6 %; obstructive in 15.8 %, and mixed in 10.5 %. In the third spirometry (n = 14), the pattern was normal in 50 %; restrictive in 21.4 %; obstructive in 14.3 %, and mixed in 14.3 %.Conclusions. In our sample of patients, a large proportion had respiratory and gastrointestinal comorbidities. Lung function worsened progressively.

Delayed Referral and Anesthetic Management of Esophageal Atresia: A Challenge for Multidisciplinary Approach?

@#Esophageal atresia (EA) is one of congenital anomaly which needs early surgical intervention in most cases. The needs of early referral to tertiary healthcare in developing countries like Indonesia may be an issue. Airway management, adequate ventilation and concomitant comorbidities are serious challenges for the anesthesiologist. We reported a case of a 31 days old infant diagnosed as esophageal atresia and fistula in the tracheoesophageal with bilateral pneumonia and early onset of sepsis. Delayed of referral due to limited access to tertiary hospital. Preoperative optimization and stabilization to deal with respiratory problems and inadequate nutrition has done before the definitive surgery. Airway management to ensure adequate ventilation done by careful endotracheal placement. Thoracic epidural catheter was inserted to deliver adequate analgesia and reduce opioid requirements. We transferred the patient to the neonatal intensive care unit following 3 hours of uneventful surgery.

Survival outcomes of trachea esophageal fistula in infant

Background: Tracheo-esophageal fistula (TEF) is a rare congenital abnormality often associated with several other anomalies including renal, vertebral column, gastrointestinal or cardiovascular defects. This study was carried out to evaluate the outcome of trachea esophageal fistula among patients who underwent various surgeries for the anastomosis of trachea esophageal fistula.Methods: This study was conducted as a record based cross sectional study among 88 patients who were diagnosed and treated for trachea-esophageal fistula in tertiary care hospital between 2015 and 2018. Data regarding the type of anomaly, presence of associated anomalies, type of surgery and outcomes were documented. Findings of echocardiography and ultrasonography were also documented. Data was analyzed using SPSS software. Chi square test was used to evaluate the outcome of the surgical procedures for management of TEF.Results: Majority of the participants in our study belong to <1 month of age and were males (56.8%). Type 3 tracheo esophageal fistula (80.7%) was the most common type. Associated cardiovascular anomalies were present in 50% of the participants. Thoracotomy with TEF repair was most preferred surgery (76%). Present study demonstrated that surgical techniques improve the physical and physiological outcome of the patients (p <0.05).Conclusions: Trachea esophageal fistula needs to be corrected with surgical procedure. Modern techniques like thorocoscopic anastomosis, thorocosopic techniques to achieve an anastomosis can also be explored. Future studies may be directed in detecting congenital anomalies during the pre-natal period with the help of genetic techniques.

Congenital Esophageal Atresia Associated with a Tracheobronchial Remnant / 대한흉부외과학회지

A rare case of esophageal atresia/tracheo-esophageal fistula (EA-TEF) with an associated tracheobronchial remnant (TBR) is reported and discussed herein. A 13-month-old patient was seen with a complaint of vomiting of solid food 1 year after EA-TEF repair. An esophagogram showed a tapered narrowing in the lower segment of the esophagus. A re-operation was carried out and a pathologic examination of the resected stenotic segment revealed the presence of a TBR.

MRI and ultrasound scan in prenatal diagnosis of congenital esophageal atresia / 中华围产医学杂志

Objective To investigate the prenatal imaging features of fetal congenital esophageal atresia and to further evaluate the value of MRI and ultrasound scan in the same condition.Methods This study recruited 12 singleton gravidas whose fetuses were initially suspected with congenital esophageal atresia by prenatal ultrasound scan and then confirmed by surgery and/or upper gastrointestinal angiography after birth at Guangzhou Women and Children's Medical Center from May 2011 to May 2017.Imaging features of prenatal MRI and ultrasonography of the 12 fetuses were retrospectively analyzed.Differences in imaging findings of these two methods were analyzed by Chi-square test.Results All 12 women received prenatal ultrasound examination and eight of them underwent MRI scan when fetal congenital esophageal atresia was suggested by ultrasound.Both ultrasound and MRI were capable of identifing polyhydramnios and absent or small stomach bubble (12/12 and 8/8,respectively).However,MRI was superior to ultrasound in detecting "pouch sign "/"oral filling sign" or poor filling of small intestine (7/8 vs 3/12 and 8/8 vs 0/12,x2 were 7.500 and 20.000,both P＜0.01).While,no statistical difference was shown in detecting curved tracheal between MRI and ultrasound (2/8 vs 0/12,x2=3.333,P=0.067).For Gross Ⅰ or Gross Ⅲ congenital esophageal atresia fetuses,no statistically significant difference was found in their imaging features (all P＞0.05).The total detection rates after 32 weeks of gestation of Gross Ⅰ and Gross Ⅲ cases were both 3/6.Conclusions Prenatal MRI is a vital supplement to ultrasound due to its high display rate of characterized features of congenital esophageal atresia.Thus,the combined use of ultrasound and MRI is of great importance for prenatal diagnosis of this fetal abnormality.

A clinical study of endoscopic balloon dilation in treatment of esophageal stenosis after neonatal esophageal atresia surgery / 中华消化内镜杂志

Objective To explore the feasibility and efficacy of endoscopic balloon dilation in treatment of esophageal stenosis caused by operation of congenital esophageal atresia. Methods A retrospective analysis was performed on data of 218 children with type Ⅲ esophageal atresia, who underwent surgery in Zhengzhou Children' s Hospital from January 2009 to December 2017. The occurrence of postoperative complications and efficacy of endoscopic balloon dilation in treatment of esophageal stenosis was analyzed. Results Among the 218 patients with congenital esophageal atresia, 92 were type Ⅲa and 126 were type Ⅲb. Postoperative anastomotic leakage occurred in 46 cases (21. 1％), including 29 (31. 5％) of type Ⅲa and 17 (13. 5％) of type Ⅲb. Postoperative anastomotic stenosis occurred in 53 cases (24. 3％), including 29 ( 31. 5％) of type Ⅲa and 24 ( 19. 0％) of typeⅢb. The incidence of anastomotic leakage and anastomotic stenosis in different types was significantly different (χ2=10. 383, P=0. 001; χ2=4. 497, P=0. 034). The 53 cases of anastomotic stenosis underwent 123 times of endoscopic balloon dilation, with mean time of 3. 5±1. 6, and were finally clinically recovery. No esophagus perforation occurred. Among them, 29 cases of type Ⅲa underwent 73 times with mean of 4. 0±1. 8, and 24 cases of type Ⅲb underwent 50 times with mean of 2. 5±0. 7. The difference between the two types was statistically significant (t=-4. 053, P=0. 027). Conclusion Children with type Ⅲa esophageal atresia has a higher incidence of anastomotic stenosis and leakage, and more times of esophageal dilation. Endoscopic balloon dilation is safe and effective in treatment of esophageal stenosis after surgery for patients with congenital esophageal atresia.
