Esophageal atresia: data from a national cohort

Determining the Risk Factors for Anastomotic Stricture Development after Esophageal Atresia Repair: Results from the Turkish Esophageal Atresia Registry

INTRODUCTION

 Anastomotic stricture (AS) is the second most common complication after esophageal atresia (EA) repair. We aimed to evaluate the data in the Turkish Esophageal Atresia Registry to determine the risk factors for AS development after EA repair in a large national cohort of patients.

METHODS

 The data between 2015 and 2021 were evaluated. Patients were enrolled into two groups according to the occurrence of AS. Patients with AS (AS group) and without AS (non-AS group) were compared according to demographic and operative features, postoperative intubation status, and postoperative complications, such as anastomotic leaks, fistula recanalization, and the presence of gastroesophageal reflux (GER). A multivariable logistic regression analysis was performed to define the risk factors for the development of AS after EA repair.

RESULTS

 Among the 713 cases, 144 patients (20.19%) were enrolled into the AS group and 569 (79.81%) in the non-AS group. The multivariable logistic regression showed that, being a term baby (odds ratio [OR]: 1.706; p = 0.006), having a birth weight over 2,500 g (OR: 1.72; p = 0.006), presence of GER (OR: 5.267; p < 0.001), or having a recurrent tracheoesophageal fistula (TEF, OR: 4.363; p = 0.006) were the risk factors for the development of AS.

CONCLUSIONS

 The results of our national registry demonstrate that 20% of EA patients developed AS within their first year of life. In patients with early primary anastomosis, birth weight greater than 2,500 g and presence of GER were risk factors for developing AS. When patients with delayed anastomosis were included, in addition to the previous risk factors, being a term baby, and having recurrent TEF also became risk factors.

Long-term Airway Outcomes and Interventions in Children With Oesophageal Atresia With Tracheoesophageal Fistula: A 20-year Single Centre Observational Study

BACKGROUND

Airway anomalies, symptoms and interventions are commonly reported in children with oesophageal atresia with tracheoesophageal fistula (OA/TOF). The purpose of this study was to assess the incidence of these airway pathologies and those requiring interventions in the long-term.

METHODS

A retrospective case note review of all patients admitted to the Neonatal Unit at the Royal Hospital for Children, Glasgow between January 2000 and December 2015 diagnosed with OA/TOF. Included patients had a minimum of 5 years follow-up.

RESULTS

121 patients were identified. 118 proceeded to OA/TOF repair. 115 patients had long-term follow-up data. Ninety-five (83%) children had one or more airway symptom recorded. Thirty-six (31%) neonates underwent airway endoscopy at the time of their initial OA/TOF repair. Forty-six (40%) children underwent airway endoscopy at a later date due to airway symptoms. Airway pathologies identified included airway malacia, thirty-two (28%), subglottic stenosis, eleven (10%), tracheal pouch, twenty-five (22%), laryngeal cleft, seven (6%) and recurrent fistula, five (4%). Airway interventions included endoscopic division of tracheal pouch, ten (9%), tracheostomy, seven (6%), aortopexy, six (5%), repair of recurrent fistula, five (4%), endoscopic repair of laryngeal cleft, three (3%) and four (3%) required open airway reconstruction for subglottic stenosis. One child (1%) remains tracheostomy dependent.

CONCLUSIONS

Long-term airway pathologies are common in children with OA/TOF. Many of these are remediable with surgical intervention. Clinicians should be cognisant of this and refer to Airway Services appropriately.

Outcomes of Premature Infants With Type C Esophageal Atresia

BACKGROUND

To review the outcomes of premature patients with type C esophageal atresia (EA).

METHODS

In this retrospective cohort study, charts of patients of type C EA patients were reviewed from 1992 to 2022. Outcomes of premature patients were compared to term patients. Preterm patients were analyzed to compare outcomes of infants with very low birth weights (VLBW) to patients >1,500 g as well as primary versus delayed anastomosis.

RESULTS

Among 192 type C EA, 67 were premature. Median and interquartile range (IQR) gestational age and birth weight of preterm patients were 34 [33-36] weeks and 1965 [1740-2290] g. Delayed anastomosis was performed in 12 (18%) preterm vs. 3 (2%) term patients (p = 0.0003). Short-term postoperative outcomes were similar between preterm and term patients, except for recurrent fistula (16% vs. 6%, p = 0.01). Prematurity was associated with an increased need for long-term enteral tube feeding (56% vs. 10%, p = 0.0001) and parenteral nutrition (10 days vs. 0 days, p = 0.0004). The length of stay was 3 times longer when patients were premature (50 days vs. 17 days, p = 0.002). Delayed surgery in preterm patients was associated with post-operative leaks, strictures, recurrent fistula, prolonged enteral tube feeding, and gastrostomy insertion. Patients with very low birth weight (VLBW) were compared to other preterm patients and showed no difference in terms of rate of delayed surgery, and post-operative outcomes.

CONCLUSION

Despite increased prematurity-related comorbidities and low birth weight, premature infants with type C EA/TEF have similar post-operative outcomes to term patients though recurrent fistula was more frequent with prematurity.

TYPE OF STUDY

Retrospective cohort study.

The French Experience with a Population-Based Esophageal Atresia Registry (RENATO)

This paper presented a national register for esophageal atresia (EA) started in January 2008. We report our experience about the conception of this database and its coordination. Data management and data quality are also detailed. In 2023, more than 2,500 patients with EA are included. Prevalence of EA in France was calculated at 1.8/10,000 live birth. Main clinical results are listed with scientific publications issued directly from the register.

Proton pump inhibitors in esophageal atresia: A systematic review and meta-analysis

Gastroesophageal reflux disease (GERD) is frequent and prolonged in esophageal atresia (EA) pediatric patients requiring routine use of proton pump inhibitors (PPIs). However, there are still controversies on the prophylactic use of PPIs and the efficacy of PPIs on GERD and EA complications in this special condition. The aim of the study is to assess the prophylactic use of PPIs in pediatric patients with EA and its complications. We, therefore, performed a systematic review including all reports on the subject from 1980 to 2022. We conducted meta-analysis of the pooled proportion of PPI-and no PPI groups using random effect model, meta-regression, and estimate heterogeneity by heterogeneity index I2 . Thirty-eight reports on the topic met the criteria selection, representing a cumulative 6044 patients with EA. Prophylactic PPI prescription during the first year of life does not appear to prevent GERD persistence at follow-up and is not associated with a significantly reduced rate of antireflux surgical procedures (ARP). PPIs improve peptic esophagitis and induce remission of eosinophilic esophagitis at a rate of 50%. Their effect on other GERD outcomes is uncertain. Evidence suggests that PPIs do not prevent anastomotic stricture, Barrett's esophagus, or respiratory complications. PPI use in EA can improve peptic and eosinophilic esophagitis but is ineffective on the other EA complications. Side effects of PPIs in EA are almost unknown.

Parents' experiences of sham feeding their child with esophageal atresia at home while awaiting reconstructive surgery. A qualitative interview study

PURPOSE

This study aimed to explore parents' experience of sham feeding their baby born with esophageal atresia at home, waiting for reconstructive surgery.

METHOD

Semi-structured interviews were conducted with parents of six children born with esophageal atresia waiting for delayed reconstruction. The interviews were analyzed using qualitative content analysis.

RESULTS

Parents experienced that sham feed reinforced the healthy abilities in their baby. They had faith in their own ability as parents to care for their child as well as to see to their baby's strength to cope with difficulties. Parents expressed that the health care system can hinder as well as be a major support on their way to a more normal life at home while waiting for reconstructive surgery.

CONCLUSION

The experience of sham feeding at home while waiting for reconstructive surgery is characterized by positive aspects both for children born with esophageal atresia and their parents.

Intestinal dysbiosis and inflammation in children with repaired esophageal atresia

OBJECTIVES

This study aims to compare the intestinal microbiota and intestinal inflammation of children with esophageal atresia (EA) to matched healthy controls, and to investigate the relationship between these factors and clinical outcomes.

METHODS

A cross-sectional study of 35 children with EA and 35 matched healthy controls (HC) from a single tertiary pediatric hospital in Australia was conducted. Demographic and dietary data were collected using surveys. Stool samples were analyzed using 16S rRNA sequencing, and fecal calprotectin measurements were used to measure intestinal inflammation. Comparisons were made between the groups, and correlations between the microbiota and clinical factors were investigated in the EA cohort.

RESULTS

Compared to HC, children with EA had similar alpha diversity, but beta diversity analysis revealed clustering of EA and HC cohorts. Children with EA had a significantly higher relative abundance of the order Lactobacillales, and a lower abundance of the genus uncultured Bacteroidales S24-7. Fecal calprotectin was significantly higher in children with EA compared to HC. In the EA cohort, children taking proton pump inhibitors (PPI's) had lower alpha diversity and higher calprotectin levels compared to those not taking PPI's. There was a negative correlation between calprotectin and length/height-for-age z scores, and children with higher calprotectin levels had a greater burden of gastrointestinal symptoms.

CONCLUSIONS

Children with EA have an altered intestinal microbiota compared to HC, which is likely related to PPI use, and may be impacting on growth and quality of life. It is important to rationalize PPI use in this cohort.

Endoscopic management of esophageal mucosal bridges in children with esophageal atresia

BACKGROUND AND STUDY AIMS

Esophageal mucosal bridge (EMB) may be diagnosed at the anastomotic site in children operated on for esophageal atresia (EA) but so far only a few cases (n = 4) have been reported. This study aimed to characterize EMB in children with EA, risk factors, and treatment.

PATIENTS AND METHODS

This retrospective multicenter study recorded patient's characteristics, EMB diagnosis circumstances, endoscopic management, follow-up, and EMB recurrence in children with EA aged less than 18 years, compared with paired EA patients without EMB.

RESULTS

Thirty patients were included (60% male, 90% EA/tracheoesophageal fistula, 43% associated malformations). Compared to 44 paired controls, EMB was associated with a history of nasogastric tube feeding (31% vs. 9.1%, p = 0.02) and severe gastroesophageal reflux disease (history of fundoplication: 41.4% vs. 13.6%, p < 0.01). 77% had symptoms (food impaction and/or dysphagia). Endoscopic management was performed in 53% of patients (83% electrocoagulation) with no technical difficulties or complications. 80% of the symptomatic patients with EMB improved after endoscopic treatment, independently of anastomotic stricture dilatation or not.

CONCLUSION

EMB endoscopic management by electrocoagulation is safe and often leads to symptom improvement.

Dynamic Imaging Grade of Swallowing Toxicity in Children with Esophageal Atresia

INTRODUCTION

 The Dynamic Imaging Grade of Swallowing Toxicity (DIGEST) scale was developed to evaluate the safety, efficiency, and overall pharyngeal swallowing performance in patients with dysphagia (DIGESTs, DIGESTe, and DIGESTt, respectively). Although various types of swallowing dysfunction are encountered in children with esophageal atresia (EA), oropharyngeal dysphagia poses risk for aspiration. Therefore, a retrospective study was performed to evaluate the safety and efficacy of swallowing by using DIGEST score in children with EA.

PATIENTS AND METHODS

 Thirty-nine EA patients were included. The demographic features, respiratory problems, results, and outcomes of surgical treatment were evaluated from medical records. The videofluoroscopic swallowing evaluation investigated for both airway protection and bolus residuals at the level of vallecula, posterior pharyngeal wall, and pyriform sinus at liquid and pudding consistencies. The penetration and aspiration scale (PAS) was used to define penetration and aspiration severity, and DIGEST was used to evaluate DIGESTs, DIGESTe, and DIGESTt.

RESULTS

 The median age of the patients were 13 months (7-39 months), and male-to-female ratio was 25:14. Sixty-seven percent of patients were type-C EA and 61% of them has associated anomalies; 38% of patients had aspiration (PAS = 6-8) in liquids and 10% in pudding consistency. Life-threatening/profound swallowing dysfunction in DIGESTe (DIGEST = 4) was seen in 13% (n = 5) of patients; 40% of EA patients showed severe problems in DIGESTt.

CONCLUSION

 DIGEST is a valid and reliable tool to define the efficacy and safety of swallowing in children with EA.

Parental risk factors for oesophageal atresia

BACKGROUND

An Oesophageal atresia (OA) affects almost 1 in 3500 newborn and its aetiology for development between 4th to 6th pregnancy weeks had not yet been clarified.

METHODS

This retrospective, observational control group-supported (n = 30) examination was performed with OA mothers (n = 20) who were interrogated via specialized questionnaires and interviews to evaluate data on medical pregnancy history including hormonal treatment, changing of life habits (nutrition, diet, medication), drug consumption (alcohol, smoking, illicit drugs) as well as exposure to nuclear waste or poisonous substance exposition. Aim was to assess risk factors during pregnancy and in particular in the first trimester.

RESULTS

The body mass index (BMI) prior pregnancy of OA mothers was significant lower (p = 0.022) and the number of mothers with obesity (BMI>30) did not differ to control group mothers (p = 0.081). They had additionally more pre-existing illnesses (p = 0.009) and allergies (p = 0.001). Control group mothers changed dietary habits with higher meat (p = 0.032) and caffeine intake (p = 0.012) compared to OA mothers, which had higher rates of abnormalities during pregnancy (p < 0.001) and 38.7% of them suffered of ≥1 abortion in the past. The ethnical background of OA mothers was more often German (p < 0.033), while OA fathers had a lower socioeconomic status (p = 0.039).

CONCLUSION

Maternal factors like previous abortions, obesity and immunological predispositions like existence of allergies combined with increased daily dairy consumption influenced obviously the occurrence of OA.

Combined esophageal and duodenal atresia: A review of the literature from 1950 to 2020

The combination of duodenal atresia (DA) and esophageal atresia (EA) is very rare. With improvements in prenatal sonography and the use of fetal magnetic resonance imaging (MRI), these malformations can be diagnosed in a more accurate and timely manner; polyhydramnios remains the most common sign despite having a low specificity. The high rate of associated anomalies (in 85% of cases) can also impact neonatal management and increase the morbidity rate; thus, it is of paramount importance to look for every possible associated malformation, such as VACTERL and chromosomic anomalies. The surgical management of this combination of atresias is not well defined and changes according to the patient's clinical status, the type of EA, and the other associated malformations. Management ranges from a primary approach for one of the atresias with delayed correction of the other (56.8%) to a simultaneous repair of both atresias (33.8%) with or without gastrostomy, or total abstention (9.4%). We suggest that a simultaneous approach can be safely performed on patients in good physical condition, with a birth weight over 1500 g, and with no major respiratory distress; this method begins by closing the tracheoesophageal fistula to protect the lung and then repairing the DA. The mortality rate has decreased over the years, dropping from 71% before 1980 to 24% after 2001. In this review, we present the available evidence on these conditions, focusing mostly on the epidemiology, prenatal diagnosis, neonatal management strategies, and outcome, with the aim of determining how the different clinical features and surgical approaches may impact on morbidity and mortality.

Delayed primary repair in 100 infants with isolated long-gap esophageal atresia: A nationwide analysis of children's hospitals

BACKGROUND

This study aimed to evaluate the contemporary surgical management of long-gap esophageal atresia, a rare and challenging problem managed by pediatric general surgeons.

METHODS

A retrospective review of the Pediatric Health Information System database for infants who underwent neonatal gastrostomy, followed by surgical reconstruction for long-gap esophageal atresia (2014-2021). Patients with birthweight less than 1.5 kg and those who received neonatal cardiac surgery were excluded. Outcomes were analyzed, including the need for further procedures, length of stay, and mortality.

RESULTS

Of 1,346 infants who underwent repair across 47 major children's hospitals, 100 (7%) met the inclusion criteria for long-gap esophageal atresia. Cardiac anomalies were identified in 43% of patients. The median age at repair was 87 days (interquartile range, 62-133). Ten percent of patients had a planned or unplanned reoperation ≤30 days after index surgery, and 4% underwent reoperation at >30 days. The median time to reoperation was 9 days (interquartile range, 7-60). Mortality during index admission was 5%, and the median hospital length of stay was 143 days (interquartile range, 101-192). Length of stay was significantly longer in patients with cardiac anomalies (cardiac: 179 days, non-cardiac: 125 days; P < .001), and 52% of patients required at least 1 postoperative dilation. The median time to the first dilation was 70 days (interquartile range, 42-173).

CONCLUSION

This large multicenter study highlights the challenges of infants with long-gap esophageal atresia but suggests a high rate of successful delayed primary reconstruction. Hospitalizations are prolonged, and anastomotic stricture rates remain high. These data are useful for pediatric surgeons in counseling families on surgical repair strategy, timing, and postoperative outcomes.

Outcome of long gap esophageal atresia at 6 years: A prospective case control cohort study

BACKGROUND DATA

EA is the most frequent congenital esophageal malformation. Long gap EA remains a therapeutic challenge for pediatric surgeons. A case case-control prospective study from a multi-institutional national French data base was performed to assess the outcome, at age of 1 and 6 years, of long gap esophageal atresia (EA) compared with non-long gap EA/tracheo-esophageal fistula (TEF). The secondary aim was to assess whether initial treatment (delayed primary anastomosis of native esophagus vs. esophageal replacement) influenced mortality and morbidity at ages 1 and 6 years.

METHODS

A multicentric population-based prospective study was performed and included all patients who underwent EA surgery in France from January 1, 2008 to December 31, 2010. A comparative study was performed with non-long gap EA/TEF patients. Morbidity at birth, 1 year, and 6 years was assessed.

RESULTS

Thirty-one patients with long gap EA were compared with 62 non-long gap EA/TEF patients. At age 1 year, the long gap EA group had longer parenteral nutrition support and longer hospital stay and were significantly more likely to have complications both early post-operatively and before age 1 year compared with the non-long gap EA/TEF group. At 6 years, digestive complications were more frequent in long gap compared to non-long gap EA/TEF patients. Tracheomalacia was the only respiratory complication that differed between the groups. Spine deformation was less frequent in the long gap group. There were no differences between conservative and replacement groups at ages 1 and 6 years except feeding difficulties that were more common in the native esophagus group.

CONCLUSIONS

Long gap strongly influenced digestive morbidity at age 6 years.

Endoscopic Management of Congenital Esophageal Defects and Associated Comorbidities

The endoscopist plays a critical role in the management of patients with congenital esophageal defects. This review focuses on esophageal atresia and congenital esophageal strictures and, in particular, the endoscopic management of comorbidities related to these conditions, including anastomotic strictures, tracheoesophageal fistulas, esophageal perforations, and esophagitis surveillance. Practical aspects of endoscopic techniques for stricture management are reviewed including dilation, intralesional steroid injection, stenting, and endoscopic incisional therapy. Endoscopic surveillance for mucosal pathology is essential in this population, as patients are at high risk of esophagitis and its late complications such as Barrett's esophagus.

Risk factors for adverse outcomes following surgical repair of esophageal atresia. A retrospective cohort study

Esophageal atresia (EA) is a life-threatening congenital malformation of the esophagus. Despite considerable recent advances in perinatal resuscitation and neonatal care, EA remains an important cause of mortality and morbidity, especially in low-income countries. The aim of this study was to assess risk factors for adverse outcomes following surgical repair of EA at a single center in Tunisia. We performed a retrospective analysis using medical records of neonates with surgical management of EA at our institution from 1 January 2007 to 31 December 2021. In total, 88 neonates were included with a mortality rate of 25%. There were 29 girls and 59 boys. The diagnosis of EA was suspected prenatally in 19 patients. The most common associated anomalies were congenital heart diseases. Prematurity, low birth weight, outborn birth, age at admission >12 hours, congenital heart disease, postoperative sepsis, and anastomotic leak were risk factors for mortality following surgical repair of EA. Anastomotic tension was the only factor associated with short-term complications and the occurrence of short-term complications was predictive of mid-term complications. This study provides physicians and families with contemporary information regarding risk factors for adverse outcomes following surgical repair of EA. Thus, any effort to reduce these risk factors would be critical to improving patient outcomes and reducing cost. Future multi-institutional studies are needed to identify, investigate, and establish best practices and clinical care guidelines for neonates with EA.

Magnetic Resonance Imaging-Based Evaluation of Anatomy and Outcome Prediction in Infants with Esophageal Atresia

INTRODUCTION

There is currently no validated diagnostic modality to characterize the anatomy and predict outcomes of tracheal esophageal defects, such as esophageal atresia (EA) and tracheal esophageal fistulas (TEFs). We hypothesized that ultra-short echo-time MRI would provide enhanced anatomic information allowing for evaluation of specific EA/TEF anatomy and identification of risk factors that predict outcome in infants with EA/TEF.

METHODS

In this observational study, 11 infants had pre-repair ultra-short echo-time MRI of the chest completed. Esophageal size was measured at the widest point distal to the epiglottis and proximal to the carina. Angle of tracheal deviation was measured by identifying the initial point of deviation and the farthest lateral point proximal to the carina.

RESULTS

Infants without a proximal TEF had a larger proximal esophageal diameter (13.5 ± 5.1 mm vs. 6.8 ± 2.1 mm, p = 0.07) when compared to infants with a proximal TEF. The angle of tracheal deviation in infants without a proximal TEF was larger than infants with a proximal TEF (16.1 ± 6.1° vs. 8.2 ± 5.4°, p = 0.09) and controls (16.1 ± 6.1° vs. 8.0 ± 3.1°, p = 0.005). An increase in the angle of tracheal deviation was positively correlated with duration of post-operative mechanical ventilation (Pearson r = 0.83, p < 0.002) and total duration of post-operative respiratory support (Pearson r = 0.80, p = 0.004).

DISCUSSION

These results demonstrate that infants without a proximal TEF have a larger proximal esophagus and a greater angle of tracheal deviation which is directly correlated with the need for longer post-operative respiratory support. Additionally, these results demonstrate that MRI is a useful tool to assess the anatomy of EA/TEF.

Retrospective evaluation of clinical and molecular data of 148 cases of esophageal atresia

Developmental abnormalities provide a unique opportunity to seek for the molecular mechanisms underlying human organogenesis. Esophageal development remains incompletely understood and elucidating causes for esophageal atresia (EA) in humans would contribute to achieve a better comprehension. Prenatal detection, syndromic classification, molecular diagnosis, and prognostic factors in EA are challenging. Some syndromes have been described to frequently include EA, such as CHARGE, EFTUD2-mandibulofacial dysostosis, Feingold syndrome, trisomy 18, and Fanconi anemia. However, no molecular diagnosis is made in most cases, including frequent associations, such as Vertebral-Anal-Cardiac-Tracheo-Esophageal-Renal-Limb defects (VACTERL). This study evaluates the clinical and genetic test results of 139 neonates and 9 fetuses followed-up at the Necker-Enfants Malades Hospital over a 10-years period. Overall, 52 cases were isolated EA (35%), and 96 were associated with other anomalies (65%). The latter group is divided into three subgroups: EA with a known genomic cause (9/148, 6%); EA with Vertebral-Anal-Cardiac-Tracheo-Esophageal-Renal-Limb defects (VACTERL) or VACTERL/Oculo-Auriculo-Vertebral Dysplasia (VACTERL/OAV) (22/148, 14%); EA with associated malformations including congenital heart defects, duodenal atresia, and diaphragmatic hernia without known associations or syndromes yet described (65/148, 44%). Altogether, the molecular diagnostic rate remains very low and may underlie frequent non-Mendelian genetic models.

Epidemiological characteristics of live births with esophageal atresia in Sao Paulo State, Brazil, from 2005 to 2018

Background

The estimated prevalence of esophageal atresia (EA) is 1 in 2500-4500 live births (LBs). Researchers have already identified risk factors, but the mechanisms are still unknown. The aim of this study is to identify EA prevalence trends and its risk factors in the São Paulo State (SPS) population database.

Methods

We conducted a population-based study using all EA cases identified by the Live Births Information System across 14 years (2005-2018) to estimate EA prevalence trends in recent years, stratified by maternal age and SPS geographical clusters. We calculated the prevalence trends, regression coefficient (β), annual percent change (APC), and 95% confidence interval (CI).

Results

We found 820 EA cases among 8,536,101 LBs with a prevalence of 1.0/10,000 LBs in SPS, Brazil. There was no significant difference in distribution by sex. Among all the cases, the majority (65%) were Caucasian; 51.8% were born at term; 43% had weight of ≥2500 g; 95.4% were singleton; and 73.4% of births were by cesarean section. From 2005 to 2018, there was an increasing trend of EA prevalence (APC=6.5%) with the highest APC of 12.2%. The highest EA prevalence rate (1.7/10,000 LB) was found in the group with maternal age of ≥35 years. No significant seasonal variation was found based on the conception month (p=0.061).

Conclusions

EA had an increasing prevalence trend in SPS, Brazil, in recent years, with the highest prevalence rate in the group with maternal age of ≥35 years. No seasonality was observed. This population-based study is the first to summarize the current epidemiology of EA in SPS LB.

Advances in Complex Congenital Tracheoesophageal Anomalies

Esophageal atresia with or without tracheoesophageal fistula and tracheobronchomalacia encompass 2 of the most common complex congenital intrathoracic anomalies. Tailoring interventions to address the constellation of problems present in each patient is essential. Due to advances in neonatology, anesthesia, pulmonary, gastroenterology, nutrition and surgery care for patients with complex congenital tracheoesophageal disorders has improved dramatically. Treatment strategies tailored to the individual patient needs are best implimented under the aegis of a comprehensive longitudinal multidisciplinary care team.

Postoperative Complications of Esophageal Atresia and Role of Endoscopic Balloon Dilatation in Anastomotic Strictures

PURPOSE

Esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) is a congenital anomaly that can cause frequent digestive and nutritional problems, even after repair. The most common complication is anastomotic stricture, for which reoperation or balloon dilatation is performed. This study aimed to evaluate the postoperative complications of EA and the role of endoscopic balloon dilatation (EBD) in cases of anastomotic stricture.

METHODS

We retrospectively analyzed patients diagnosed with EA with or without TEF between January 2000 and February 2021. Patients' baseline characteristics, associated anomalies, and postoperative complications were reviewed.

RESULTS

Among 26 patients, 14 (53.8%) were male, 12 (46.2%) had coexisting anomalies, and the median follow-up was 6.1 years (range, 1.2-15.7 years). In univariate analysis, prematurity, low birth weight, and long-gap EA were associated with postoperative complications in 12 (46.2%) patients. Among the 10 (38.5%) patients with anastomotic stricture, nine (90.0%) required EBD. Regarding the first EBD, it was performed at a median of 3.3 months (range, 1.2-7.6 months) post-repair, while the average patient weight was 4.6 kg. The mean diameter ranged from 3.3 to 9.1 mm without major complications. In univariate analysis, long-gap EA alone was significantly associated with EBD.

CONCLUSION

Approximately half of the patients experienced complications after EA repair. In particular, patients with a long-gap EA had a significantly increased risk of complications, such as anastomotic strictures. EBD can be safely used, even in infants.

Operative Volume of Newborn Surgery in German University Hospitals: High Volume Versus Low Volume Centers

INTRODUCTION

 Adequate patient volume is essential for the maintenance of quality, meaningful research, and training of the next generation of pediatric surgeons. The role of university hospitals is to fulfill these tasks at the highest possible level. Due to decentralization of pediatric surgical care during the last decades, there is a trend toward reduction of operative caseloads. The aim of this study was to assess the operative volume of the most relevant congenital malformations at German academic pediatric surgical institutions over the past years.

METHODS

 Nineteen chairpersons representing university-chairs in pediatric surgery in Germany submitted data on 10 index procedures regarding congenital malformations or neonatal abdominal emergencies over a 3-year period (2015 through 2017). All institutions were categorized according to the total number of respective cases into "high," "medium," and "low" volume centers by terciles. Some operative numbers were verified using data from health insurance companies, when available. Finally, the ratio of cumulative case load versus prevalence of the particular malformation was calculated for the study period.

RESULTS

 From 2015 through 2017, a total 2,162 newborns underwent surgery for congenital malformations and neonatal abdominal emergencies at German academic medical centers, representing 51% of all expected newborn cases nationwide. The median of cases per center within the study period was 101 (range 18-258). Four institutions (21%) were classified as "high volume" centers, four (21%) as "medium volume" centers, and 11 (58%) as "low volume" centers. The proportion of patients operated on in high-volume centers varied per disease category: esophageal atresia/tracheoesophageal fistula: 40%, duodenal atresia: 40%, small and large bowel atresia: 39%, anorectal malformations: 40%, congenital diaphragmatic hernia: 56%, gastroschisis: 39%, omphalocele: 41%, Hirschsprung disease: 45%, posterior urethral valves: 39%, and necrotizing enterocolitis (NEC)/focal intestinal perforation (FIP)/gastric perforation (GP): 45%.

CONCLUSION

 This study provides a national benchmark for neonatal surgery performed in German university hospitals. The rarity of these cases highlights the difficulties for individual pediatric surgeons to gain adequate clinical and surgical experience and research capabilities. Therefore, a discussion on the centralization of care for these rare entities is necessary.

Predictors of anastomotic strictures following œsophageal atresia repair

OBJECTIVES

To identify the risk factors for anastomotic, refractory and recurrent strictures and to establish whether anastomotic stricture is associated with antireflux surgery.

DESIGN

This prospective national multicentre study included all infants born with oesophageal atresia (OA) over an 8-year period. Data on OA and complications were collected at birth and at 1 year old. Univariate and multivariate analyses were conducted.

RESULTS

1082 patients from 37 centres were included in the study. The prevalence of anastomotic stricture at 1 year old was 23.2%. Anastomosis under tension (defined by the surgeon at the time of repair) and delayed anastomosis (defined as anastomosis performed more than 15 days after birth, excluding delays due to prematurity or severe cardiac diseases) were found to be independent risk factors for anastomotic stricture (2.3 (1.42-3.74) and 4.02 (2.12-7.63), respectively). Patients with anastomotic stricture had a 2.3-fold higher rate of fundoplication compared with others (p=0.001). Anastomosis under tension and delayed anastomosis were found to be independent risk factors for recurrent stricture (1.92 (1.10-3.34) and 5.73 (2.71-12.14), respectively), while delayed anastomosis was the only risk factor for refractory stricture (8.30 (3.34-20.64)). There was a 2.39-fold (1.42-4.04) higher rate of fundoplication in the anastomotic stricture group than in the group without anastomotic stricture (p=0.001).

CONCLUSIONS

Patient-related anatomical factors leading to anastomosis under tension and delayed anastomosis increase the risk of anastomotic stricture.

Evaluating the Dietary Intake of Children With Esophageal Atresia: A Prospective, Controlled, Observational Study

OBJECTIVES

Children with esophageal atresia (EA) often have feeding difficulties and dysphagia, which may compromise their nutritional status. This study aimed to compare dietary intake between children with EA and matched healthy controls (HC) and to investigate the relationship between dietary factors, growth, dysphagia, and feeding difficulties in the EA cohort.

METHODS

This cross-sectional cohort study recruited children with EA and HC aged 2-17 years from a tertiary pediatric hospital in Australia. Growth parameters were measured. Dietary intake was assessed using the validated Australian Child and Adolescent Eating Survey. Dysphagia and feeding difficulties were assessed using objective questionnaires.

RESULTS

Twenty-one children with EA were matched for age and sex with 21 HC. Compared to HC, children with EA had lower mean z scores for height-for-age, but mean weight-for-age and body mass index-for-age z scores were similar. Energy intake was similar between the groups. The diet of children with EA consisted of a higher proportion of fats and lower proportion of carbohydrates compared to matched HC. Dysphagia severity in children with EA positively correlated with proportion of energy from fats and saturated fats.

CONCLUSIONS

Children with EA have similar energy intake and growth parameters to HC, but their diet consists of a higher proportion of fats and lower proportion of carbohydrates compared to HC. Targeted dietary interventions and parental education are necessary.

Reliability and Validity of the Polish Version of the Esophageal-Atresia-Quality-of-Life Questionnaires to Assess Condition-Specific Quality of Life in Children and Adolescents Born with Esophageal Atresia

Aim: This study reports the reliability and validity of the Polish version of the Esophageal Atresia Quality of Life (EA-QOL) questionnaires, which were originally developed in Sweden and Germany. Methods: A total of 50 families of children (23 aged 2 to 7, and 27 aged 8 to 17) with EA/TEF (esophageal atresia/tracheoesophageal fistula) participated in the study. The development and validation of the Polish version of the EA-QOL involved forward-backward translation of the survey items following the guidelines for cross-cultural translation, cognitive debriefing and evaluation of psychometric properties, including assessment of internal and retest reliability, linguistic validity, content validity, known-group validity and convergent validity. The medical records of patients and standardized questionnaires were used to obtain clinical data. The level of significance was p < 0.05. Results: The Polish versions of the EA-QOL questionnaires demonstrated strong linguistic and content validity, are slightly discriminative for esophageal and respiratory problems, but do not show convergent validity with the PedsQL 4.0 generic core scales. In terms of reliability, the internal consistency of the subscale and total scale of Polish versions as measured by Cronbach’s alpha is good, and retest reliability is excellent. Conclusions: The Polish versions of the EA-QOL questionnaires meet most psychometric criteria that confirm the EA-QOL questionnaires’ reliability and validity. This study enables application of these questionnaires in future research among children with EA in Poland and participation in international multicenter studies focusing on advancing knowledge of condition-specific QOL in this population. Future cross-cultural research using larger sample sizes is still needed to better address the relationship between condition-specific and generic QOL, as well as the discriminative ability of the EA-QOL questionnaires.

The Phenotypical Profile and Outcomes of Neonates with Congenital Tracheoesophageal Fistula Associated with Congenital Cardiac Anomalies Presenting for Surgery

(1) Background: Neonates born with oesophageal atresia and/or tracheooesophageal fistula (OA/TOF) are usually born with a multitude of other congenital anomalies, which may affect their anaesthetic care and survival to hospital discharge. We reviewed the profile and outcome of neonates with OA/TOF and associated congenital cardiac anomalies presenting for surgery at an academic hospital in South Africa. (2) Methods: A retrospective, cross-sectional analysis of all medical records of neonates who had undergone surgical repair of OA/TOF was conducted at an academic hospital between January 2015 and December 2019. Descriptive statistics were used to report the data. Comparisons in perioperative events and outcomes between those with cardiac lesions and those without were done. (3) Results: Neonates presenting for OA/TOF repair with congenital cardiac defects had an incidence of 62 [95% CI 38.5–99.8] per 1000 days since birth. In total, 45.9% had associated cardiac anomalies, with PDA and ASD as the most prevalent lesions. There were statistically significant differences in intraoperative adverse events seen in neonates with congenital cardiac lesions as compared to those without. (4) Conclusion: Despite advances in neonatal critical care and anaesthetic and surgical techniques, OA/TOF associated with congenital cardiac anomalies is still associated with high mortality rates in developing countries.

Current outcomes of infants with esophageal atresia and tracheoesophageal fistula: A multicenter analysis

OBJECTIVE

This study aims to quantify mortality rates and hospital lengths of stay (LOS) in neonates with esophageal atresia and tracheoesophageal fistula (EA/TEF), and to characterize the effects of birth weight (BW) and associated congenital anomalies upon these.

METHODS

Data regarding patients with EA/TEF were prospectively collected (2013-2019) at 298 North American centers. The primary outcome was mortality and secondary outcome was LOS.  Risk factors affecting mortality and LOS were assessed.

RESULTS

EA/TEF was diagnosed in 3290 infants with a median BW of 2476 g (IQR 1897,2970). In-hospital mortality was 12.7%. Mortality was inversely correlated with BW. After adjustment, the risk of mortality decreased by approximately 11% with every 100 g increase in BW. A significant congenital anomaly other than EA/TEF was diagnosed in 37.9% of patients. Risk of mortality increased in patients with associated congenital anomalies, most notably in those with a severe cardiac anomaly. Lower BW was associated with an increased mean LOS among survivors. Similar to mortality risk, additional anomalies were associated with prolonged LOS.

CONCLUSIONS

This study demonstrates an in-hospital mortality of over 10%. Both increased mortality and prolonged LOS are highly associated with lower birth weight and the presence of concomitant congenital anomalies.

Time to Death and Predictors Among Neonates with Esophageal Atresia in Ethiopia

Background

Esophageal atresia is an upper gastrointestinal tract developmental abnormality in which the upper and lower esophagus do not connect. Esophageal atresia has a higher incidence of death in sub-Saharan Africa, ranging from 30% to 80%. In Ethiopia, infants with esophageal atresia had a higher mortality rate. The assessment of time to death and predictors of esophageal atresia can help to reduce newborn mortality.

Objective

This study was aimed to investigate the time to death and predictors of neonates with esophageal atresia admitted to Tikur Anbessa Specialized Hospital, Ethiopia.

Methods

An institutional-based retrospective follow-up study was conducted among 225 neonates diagnosed with esophageal atresia. The median survival time, Kaplan–Meier failure estimation curve, and Log rank test were computed. Bivariable and multivariable Cox regression hazards models were fitted to identify the predictors of time to death. Hazard ratio with a 95% confidence interval was calculated and p-values <0.05 were considered statistically significant.

Results

In the study, the incidence density rate of neonates diagnosed with esophageal atresia was 5.5 (95% CI, 4.7–6.4) per 100-neonates day. The median time to death was 11 days (95% confidence interval (CI), 8.92–13.08). Birth weight <2500 g (adjusted hazard ratio (AHR)=1.49, 95% CI, 1.02 −2.21), having sepsis (AHR=1.67,95% CI, 1.15–2.44), being malnourished (AHR = 1.61, 95% CI, 1.03 −2.58), esophageal atretic neonates without surgery (AHR = 3.72, 95% CI, 1.34–10.38), diagnosis time at >48 hours of admission (AHR = 1.48, 95% CI, 1.01–2.15) and being dehydrated (AHR = 2.38, 95% CI, 1.63–3.46) were significant predictors of time to death among esophageal atretic neonates.

Conclusion

The findings in this study highlighted the necessity of early diagnosis, proper comorbidity treatment, and timely surgical intervention to reduce infant deaths due to esophageal atresia.

From the Ground Up: Esophageal Atresia Types, Disease Severity Stratification and Survival Rates at a Single Institution

Esophageal atresia (EA), although a rare congenital anomaly, represents one of the most common gastrointestinal birth defects. There is a gap in our knowledge regarding the impact of perioperative critical care in infants born with EA. This study addresses EA types, disease severity stratification, and mortality in a retrospective cohort at a single institution. Institutional Review Board approved our retrospective cross-sectional study of term-born (n = 53) and premature infants (28–37 weeks of gestation; n = 31) that underwent primary surgical repair of EA at a single institution from 2009–2020. Demographic and clinical data were obtained from the electronic medical record, Powerchart (Cerner, London, UK). Patients were categorized by (i) sex, (ii) gestational age at birth, (iii) types of EA (in relation to respiratory tract anomalies), (iv) co-occurring congenital anomalies, (v) severity of disease (viz. American Society of Anesthesiologists (ASA) and Pediatric Risk Assessment (PRAm) scores), (vi) type of surgical repair for EA (primary anastomosis vs. Foker process), and (vii) survival rate classification using Spitz and Waterston scores. Data were presented as numerical sums and percentages. The frequency of anatomical types of EA in our cohort parallels that of the literature: 9.5% (8/84) type A, 9.5% (8/84) type B, 80% (67/84) type C, and 1% (1/84) type D. Long-gap EA accounts for 88% (7/8) type A, 75% (6/8) type B, and 13% (9/67) type C in the cohort studied. Our novel results show a nearly equal distribution of sex per each EA type, and gestational age (term-born vs. premature) by anatomical EA type. PRAm scoring showed a wider range of disease severity (3–9) than ASA scores (III and IV). The survival rate in our EA cohort dramatically increased in comparison to the literature in previous decades. This retrospective analysis at a single institution shows incidence of EA per sex and gestational status for anatomical types (EA type A-D) and by surgical approach (primary anastomosis vs. Foker process for short-gap vs. long-gap EA, respectively). Despite its wider range, PRAm score was not more useful in predicting disease severity in comparison to ASA score. Increased survival rates over the last decade suggest a potential need to assess unique operative and perioperative risks in this unique population of patients. Presented findings also represent a foundation for future clinical studies of outcomes in infants born with EA.

Feeding disorders in children with oesophageal atresia: a cross-sectional study

INTRODUCTION

With advances in surgical and neonatal care, the survival of patients with oesophageal atresia (OA) has improved over time. Whereas a number of OA-related conditions (delayed primary anastomosis, anastomotic stricture and oesophageal dysmotility) may have an impact on feeding development and although children with OA experience several oral aversive events, paediatric feeding disorders (PFD) remain poorly described in this population. The primary aim of our study was to describe PFD in children born with OA, using a standardised scale. The secondary aim was to determine conditions associated with PFD.

METHODS

The Feeding Disorders in Children with Oesophageal Atresia Study is a national cohort study based on the OA registry from the French National Network. Parents of children born with OA between 2013 and 2016 in one of the 22 participating centres were asked to complete the French version of the Montreal Children's Hospital Feeding Scale.

RESULTS

Of the 248 eligible children, 145 children, with a median age of 2.3 years (Q1-Q3 1.8-2.9, min-max 1.1-4.0 years), were included. Sixty-one children (42%) developed PFD; 13% were tube-fed (n=19). Almost 40% of children with PFD failed to thrive (n=23). The presence of chronic respiratory symptoms was associated with the development of PFD. Ten children with PFD (16%) had no other condition or OA-related complication.

CONCLUSION

PFD are common in children with OA, and there is no typical profile of patients at risk of PFD. Therefore, all children with OA require a systematic screening for PFD that could improve the care and outcomes of patients, especially in terms of growth.

Association of operative approach with outcomes in neonates with esophageal atresia and tracheoesophageal fistula

PURPOSE

We sought to evaluate the impact of thoracoscopic repair on perioperative outcomes in infants with esophageal atresia and tracheoesophageal fistula (EA/TEF).

METHODS

The American College of Surgeons National Surgical Quality Improvement Program pediatric database from 2014 to 2018 was queried for all neonates who underwent operative repair of EA/TEF. Operative approach based on intention to treat was correlated with perioperative outcomes, including 30-day postoperative adverse events, in logistic regression models.

RESULTS

Among 855 neonates, initial thoracoscopic repair was performed in 133 (15.6%) cases. Seventy (53%) of these cases were converted to open. Those who underwent thoracoscopic repair were more likely to be full-term (p = 0.03) when compared to those in the open repair group. There were no significant differences in perioperative outcome measures based on surgical approach except for operative time (thoracoscopic: 217 min vs. open: 180 min, p<0.001). A major cardiac comorbidity (OR 1.6, 95% CI 1.2-2.1; p = 0.003) and preoperative ventilator requirement (OR 1.4, 95% CI 1.0-1.9; p = 0.034) were the only risk factors associated with adverse events.

CONCLUSIONS

Thoracoscopic neonatal repair of EA/TEF continues to be used sparingly, is associated with high conversion rates, and has similar perioperative outcomes when compared to open repair.

Long term digestive outcome of œsophageal atresia

Œsophageal atresia is a rare neonatal malformation consisting in an interruption of the continuity of the œsophagus, with or without a tracheo-œsophageal fistula. Although mortality rate is now low and most cases can benefit from successful surgical repair soon after birth, morbidity -specially digestive and nutritional-remains high. Many of the adults born with œsophageal atresia will suffer from dysphagia, gastro-œsophageal reflux and/or œsophageal dysmotility, leading to nutritional consequences and quality of life impairment. Barrett's œsophagus, potential risk of œsophageal cancer as well as risk of anastomotic stenosis and eosinophilic œsophagitis justify transition to adulthood and a lifelong prolonged follow-up.

Esophageal Atresia and Respiratory Morbidity

BACKGROUND AND OBJECTIVES

Respiratory diseases are common in children with esophageal atresia (EA), leading to increased morbidity and mortality in the first year. The primary study objective was to identify the factors associated with readmissions for respiratory causes in the first year in EA children.

METHODS

A population-based study. We included all children born between 2008 and 2016 with available data and analyzed factors at birth and 1 year follow-up. Factors with a P value <.10 in univariate analyses were retained in logistic regression models.

RESULTS

Among 1460 patients born with EA, 97 (7%) were deceased before the age of 1 year, and follow-up data were available for 1287 patients, who constituted our study population. EAs were Ladd classification type III or IV in 89%, preterm birth was observed in 38%, and associated malformations were observed in 52%. Collectively, 61% were readmitted after initial discharge in the first year, 31% for a respiratory cause. Among these, respiratory infections occurred in 64%, and 35% received a respiratory treatment. In logistic regression models, factors associated with readmission for a respiratory cause were recurrence of tracheoesophageal fistula, aortopexy, antireflux surgery, and tube feeding; factors associated with respiratory treatment were male sex and laryngeal cleft.

CONCLUSIONS

Respiratory morbidity in the first year after EA repair is frequent, accounting for >50% of readmissions. Identifying high risk groups of EA patients (ie, those with chronic aspiration, anomalies of the respiratory tract, and need for tube feeding) may guide follow-up strategies.

Anxiety and Depression in Parents of Children Born with Esophageal Atresia: An International Online Survey Study

PURPOSE

Caring for a chronically ill child can be stressful and requires additional care from parents. Parental mental health and stress may impact both parental and child wellbeing, leading to maladaptive parenting practices, and interference with illness management. The aim of the study was to explore the levels of anxiety and depression in parents of children born with esophageal atresia (EA) and to investigate whether parental anxiety and depression were associated with child's medical characteristics or with parental factors.

DESIGN AND METHODS

An international online survey was developed and disseminated to parents of children born with EA, aged 0-12 years, via EA patient charity social network sites. A one-way between subjects ANOVA and post hoc statistical analyses were used to examine differences in mean scores of parental anxiety and depression between sub-groups that described child's medical characteristics and parental characteristics.

RESULTS

A total of 240 parents completed the survey from 17 different countries. Of these, nearly 70% self-reported raised levels of anxiety, whilst 38% self-reported raised levels of depression. Statistically significant differences in mean scores of parental anxiety and depression were found between sub-groups that described the child's feeding problems, parental age, and perceived support for caring, caring stress and money matters.

CONCLUSION

Child's feeding problems related to esophageal atresia, and parental factors, such as younger age, perceived lack of support for caring, caring stress, and money worries, may contribute to the increased levels of parental anxiety and depression in parents of children born with EA.

Thoracoscopic Repair of Esophageal Atresia

Background: Esophageal atresia (EA) is a rare congenital malformation of the esophagus. Surgical treatment is required to restore the continuity of the esophagus. This can be performed through thoracotomy. However, an increasing number of hospitals is performing minimal invasive surgery (MIS). In this article, we describe the technique of thoracoscopic repair of EA in neonates in more detail and show the outcome of a patient cohort operated by young pediatric surgeons in training. Methods: Between 2014 and 2019 correction was performed in 64 EA type C patients at the UMC Utrecht, Wilhelmina Children's Hospital, mainly by young pediatric surgeons in training. Results: All patients were corrected through MIS, 3 days after birth. The median operation duration was 181 (127-334) minutes. Nasogastric tube feeding was started on the first postoperative day, and oral feeding 6 days postop. Postoperative complications included leakage (14.1%), stenosis (51.1%), and recurrent tracheoesophageal fistula (7.8%). Conclusion: Thoracoscopic repair of EA can be performed safely, with good outcome and all the benefits of MIS. However, it remains a challenging procedure and should be performed only in pediatric centers with a vast experience in MIS, especially when training young pediatric surgeons. These centers must have access to a multidisciplinary team of neonatologists, pediatric anesthesiologists, surgeons, and ENT specialists to ensure the best possible care in hemodynamic, respiratory, and cerebral monitoring and gastrointestinal and developmental outcome.

Risk Factors of Early Mortality and Morbidity in Esophageal Atresia with Distal Tracheoesophageal Fistula: A Population-Based Cohort Study

OBJECTIVE

To identify the risk factors for early mortality and morbidity in a population with distal esophageal atresia (EA)-tracheoesophageal fistula.

STUDY DESIGN

Cohort study from a national register. Main outcomes and measures included early mortality, hospital length of stay (LoS), need for nutritional support at 1 year of age as a proxy measure of morbidity, and complications during the first year of life.

RESULTS

In total, 1008 patients with a lower esophageal fistula were included from January 1, 2008, to December 31, 2014. The survival rate at 3 months was 94.9%. The cumulative hospital LoS was 31.0 (17.0-64.0) days. Multivariate analysis showed that intrahospital mortality at 3 months was associated with low birth weight (OR 0.52, 95% CI [0.38-0.72], P < .001), associated cardiac abnormalities (OR 6.09 [1.96-18.89], P = .002), and prenatal diagnosis (OR 2.96 [1.08-8.08], P = .034). LoS was associated with low birth weight (-0.225 ± 0.035, P < .001), associated malformations (0.082 ± 0.118, P < .001), surgical difficulties (0.270 ± 0.107, P < .001), and complications (0.535 ± 0.099, P < .001) during the first year of life. Predictive factors for dependency on nutrition support at 1 year of age were complications before 1 year (OR 3.28 [1.23-8.76], P < .02) and initial hospital LoS (OR 1.96 [1.15-3.33], P < .01).

CONCLUSIONS

EA has a low rate of early mortality, but morbidity is high during the first year of life. Identifying factors associated with morbidity may help to improve neonatal care of this population.

Outcome of Very Low and Low Birth Weight Infants with Esophageal Atresia: Results of the Turkish Esophageal Atresia Registry

INTRODUCTION

 The data of the Turkish Esophageal Atresia Registry (TEAR) was evaluated to define the outcome of very low birth weight (VLBW) and low BW (LWB) infants with esophageal atresia (EA).

MATERIALS AND METHODS

 The data registered by 24 centers between 2014 and 2018 were evaluated for demographic features, prenatal findings, associated anomalies, surgical treatment, and outcome. Patients were enrolled in three groups according to their BWs (VLBW <1,500 g), LWB = 1,500-2,500 g), and normal BW (NBW; >2,500 g).

RESULTS

 Among the 389 cases, there were 37 patients (9.5%) in the VLBW group, 165 patients (42.4%) in the LBW group, and 187 patients (48.1%) in the NBW group. Prenatal diagnosis rates were similar among the three groups (29.7, 34.5, and 24.6%, respectively). The standard primary anastomosis was achieved at a significantly higher rate in NWB cases than in the other groups (p < 0.05). In patients with tracheoesophageal fistula (TEF), patients of the NBW group had significantly higher rates of full oral feedings, when compared with VLBW and LBW cases (p < 0.05). At the end of the first year, when we evaluate all patients, the number of cases with fistula recanalization and esophageal anastomotic strictures (AS) requiring esophageal dilatation was similar among the groups. The weight and height measurements at 6 months and 1 year of age of the survivors were similar in all the groups. The overall mortality rate was significantly higher in the VLBW and LBW groups, when compared with the NBW patients, even in patients with tension-free anastomosis (p < 0.05). The incidence of the associated anomalies was 90.6% in cases with mortality, which was significantly higher than in survivors (59.6%; p < 0.05). According to Spitz's classification, the survival rate was 87.1% in class I, 55.3% in class II, and 16.7% in class III. The most common causes of mortality were associated with cardiovascular diseases, pneumonia, and sepsis.

CONCLUSION

 The national data of TEAR demonstrates that the developmental and feeding parameters are better in NBW patients. Although VLBW patients have higher risk of developing fistula canalization than the LBW and NBW groups, long-term complications, such as anastomotic strictures, weight, and height values, after 1 year are similar in both groups. According to our results, associated anomalies and LBWs are still significant risk factors for mortality in cases with EA.

Survival of infants born with esophageal atresia among 24 international birth defects surveillance programs

BACKGROUND

Esophageal atresia (EA) affects around 2.3-2.6 per 10,000 births world-wide. Infants born with this condition require surgical correction soon after birth. Most survival studies of infants with EA are locally or regionally based. We aimed to describe survival across multiple world regions.

METHODS

We included infants diagnosed with EA between 1980 and 2015 from 24 birth defects surveillance programs that are members of the International Clearinghouse for Birth Defects Surveillance and Research. We calculated survival as the proportion of liveborn infants alive at 1 month, 1- and 5-years, among all infants with EA, those with isolated EA, those with EA and additional anomalies or EA and a chromosomal anomaly or genetic syndrome. We also investigated trends in survival over the decades, 1980s-2010s.

RESULTS

We included 6,466 liveborn infants with EA. Survival was 89.4% (95% CI 88.1-90.5) at 1-month, 84.5% (95% CI 83.0-85.9) at 1-year and 82.7% (95% CI 81.2-84.2) at 5-years. One-month survival for infants with isolated EA (97.1%) was higher than for infants with additional anomalies (89.7%) or infants with chromosomal or genetic syndrome diagnoses (57.3%) with little change at 1- and 5-years. Survival at 1 month improved from the 1980s to the 2010s, by 6.5% for infants with isolated EA and by 21.5% for infants with EA and additional anomalies.

CONCLUSIONS

Almost all infants with isolated EA survived to 5 years. Mortality was higher for infants with EA and an additional anomaly, including chromosomal or genetic syndromes. Survival improved from the 1980s, particularly for those with additional anomalies.

Delayed Diagnosis in Esophageal Atresia and Tracheoesophageal Fistula: Case Study

BACKGROUND

Timely identification of esophageal atresia is challenging. Diagnosis may be suspected antenatally with a combination of polyhydramnios, associated with a small or absent stomach bubble or other anomalies. Esophageal atresia can be suspected postnatally in the presence of tachypnea, increased oral secretions, and an inability to advance an orogastric tube. Failure to recognize an esophageal atresia can have life-threatening implications.

CLINICAL FINDINGS

A 5-day-old infant with a history of failure to thrive and respiratory distress presented in a community emergency department following a prolonged apnea associated with a breastfeed.

PRIMARY DIAGNOSIS

Delayed postnatal diagnosis of esophageal atresia and tracheoesophageal fistula.

INTERVENTIONS

During stabilization in the emergency department, a nasogastric tube was placed to decompress the stomach. A subsequent chest and abdominal radiograph identified the nasogastric tube curled in the upper esophagus, confirming an esophageal atresia. The abdominal radiograph demonstrated gaseous distension, suggesting the presence of a distal tracheoesophageal fistula.

OUTCOMES

The neonate had a primary esophageal anastomosis and fistula ligation in a surgical neonatal unit. He was discharged home at 29 days of life.

PRACTICE RECOMMENDATIONS

Understanding the challenges of an antenatal diagnosis and awareness of postnatal presentation with a view to improving postnatal recognition and better-quality outcomes for infants with an esophageal atresia and tracheoesophageal fistula.

Risk factors for digestive morbidities after esophageal atresia repair

Esophageal atresia with/without tracheoesophageal fistula (EA/TEF) is a congenital digestive tract anomaly that represents a major therapeutic challenge. Postoperative digestive morbidities such as gastroesophageal reflux disease (GERD) and esophageal stricture are common. The aim of this study was to identify the incidence of and potential risk factors for digestive morbidities after EA/TEF repair. We retrospectively reviewed all EA/TEF patients who underwent repair at a single institution between January 1999 and December 2018, excluding patients who died prior to discharge. Patient demographics, perioperative management, and postoperative GERD and esophageal stricture rates were collected. We performed univariate and multivariate analyses to examine risk factors associated with postoperative GERD and esophageal stricture. The study enrolled 58 infants (58.6% male, 17.2% with type A EA/TEF, 62.1% with associated anomalies). Postoperative GERD occurred in 67.2% of patients and was the most common digestive morbidity. Esophageal stricture occurred in 37.9% of patients after EA/TEF repair. Multivariate analysis showed that long-gap EA/TEF and postoperative GERD were independent risk factors for esophageal stricture after repair surgery.Conclusion: The incidence of postoperative GERD and esophageal stricture was 67.2% and 37.9%, respectively. The risk factors for postoperative esophageal stricture were long-gap EA/TEF and postoperative GERD. What is Known: • EA/TEF is a congenital digestive tract anomaly with a high postoperative survival rate but can be complicated by many long-term morbidities. What is New: • Long-gap EA/TEF and postoperative GERD are risk factors of anastomotic stricture after repair. • Surgeons and pediatricians should be highly experienced in managing anastomotic tension and the GERD.

Prevalence of and Risk Factors for Sagittal Posture Abnormalities in Children Born With Esophageal Atresia: A Prospective Cohort Study

Introduction: Scoliosis is a well-described complication of esophageal atresia (EA) caused by the associated spine malformations and/or thoracotomy. However, the sagittal posture abnormalities in patients with EA have not been described. The aim of this study was to evaluate the prevalence of and risk factors for sagittal posture abnormalities at the age of 6 years in patients operated on for EA. Methods: A prospective cohort of 123 patients with EA was examined by the same rehabilitation doctor at the time of a multidisciplinary visit scheduled at the age of 6 years. Children presenting with scoliosis (n = 4) or who missed the consultation (n = 33) were excluded. Univariate and multivariate logistic regression models with Firth's penalized-likelihood approach were used to identify risk factors associated with sagittal posture anomalies. Candidate risk factors included neonatal characteristics, associated malformations, atresia type, postoperative complications, psychomotor development retardation, orthopedic abnormalities, and neurological hypotonia. Results: The prevalence rates of sagittal posture abnormalities were 25.6% (n = 22; 95% CI, 16.7-36.1%). Multivariate analysis showed that minor orthopedic abnormalities (OR: 4.02, 95% CI: 1.29-13.43, P = 0.021), and VACTERL (OR: 3.35, 95% CI: 1.09-10.71, P = 0.042) were significant risk factors for sagittal posture abnormalities. Conclusion: This study shows that sagittal posture anomalies occur frequently in children operated on at birth for EA and are not directly linked to the surgical repair. These children should be screened and treated using postural physiotherapy, especially those with VACTERL and minor orthopedic abnormalities.

ERNICA Consensus Conference on the Management of Patients with Esophageal Atresia and Tracheoesophageal Fistula: Follow-up and Framework

INTRODUCTION

 Improvements in care of patients with esophageal atresia (EA) and tracheoesophageal fistula (TEF) have shifted the focus from mortality to morbidity and quality-of-life. Long-term follow-up is essential, but evidence is limited and standardized protocols are scarce. Nineteen representatives of the European Reference Network for Rare Inherited Congenital Anomalies (ERNICA) from nine European countries conducted a consensus conference on the surgical management of EA/TEF.

MATERIALS AND METHODS

 The conference was prepared by item generation (including items of surgical relevance from the European Society for Pediatric Gastroenterology Hepatology and Nutrition (ESPGHAN)-The North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) guidelines on follow-up after EA repair), item prioritization, formulation of a final list containing the domains Follow-up and Framework, and literature review. Anonymous voting was conducted via an internet-based system. Consensus was defined as ≥75% of those voting with scores of 6 to 9.

RESULTS

 Twenty-five items were generated in the domain Follow-up of which 17 (68%) matched with corresponding ESPGHAN-NASPGHAN statements. Complete consensus (100%) was achieved on seven items (28%), such as the necessity of an interdisciplinary follow-up program. Consensus ≥75% was achieved on 18 items (72%), such as potential indications for fundoplication. There was an 82% concordance with the ESPGHAN-NASPGHAN recommendations. Four items were generated in the domain Framework, and complete consensus was achieved on all these items.

CONCLUSION

 Participants of the first ERNICA conference reached significant consensus on the follow-up of patients with EA/TEF who undergo primary anastomosis. Fundamental statements regarding centralization, multidisciplinary approach, and involvement of patient organizations were formulated. These consensus statements will provide the cornerstone for uniform treatment protocols and resultant optimized patient care.

Esophageal Atresia: Nutritional Status and Energy Metabolism to Maximize Growth Outcome

BACKGROUND

Long-term negative sequelae of esophageal atresia (EA) may induce poor growth and impaired nutritional status in childhood. We describe the nutritional profile and energy metabolism of children with repaired EA to identify malnutrition risk factors and optimize growth management.

METHODS

Twenty-one children (>4 years) were included, and anthropometric measurements, nutritional assessment, and energy metabolism were considered. The subjects were defined as undernourished if they met BMI < -2 standard deviation (SD). To grade undernutrition, we defined the prevalence of underweight, stunting, and wasting (cut-off level of <-2 SD). Medical records were reviewed for the type of EA and surgery and perinatal data.

RESULTS

Malnutrition was detected in 28.6% of children. Underweight was detected in 23.8% of patients (all with undernutrition p < 0.01). Wasting was noted in 28.6% of patients, of these 5 children were undernourished (p < 0.001) and stunting was noticed in only one patient with malnutrition (p = 0.5). Resting expenditure energy (REE) was lower in undernourished subjects compared to subjects with adequate nutritional status (p < 0.001). Malnutrition was associated to: type of EA (p = 0.003, particularly type A and C); intervention including deferred anastomosis due to long-gap repair (p = 0.04) with/or without jejunostomy (p = 0.02), gastric pull-up (p = 0.04), primary anastomosis (p = 0.04), pyloromyotomy in long-gap (p < 0.01); small for gestational age condition (p = 0.001).

CONCLUSIONS

undernutrition risk factors, beyond the type of malformation, surgery, and perinatal factors, must be early considered to personalize nutritional programming. Energy metabolism is important to monitor the nutritional requirements. The management of nutritional issues is surely a contributory factor able to counteract the poor growth of children with EA.

Epidemiology and risk factors for eosinophilic esophagitis: lessons for clinicians

INTRODUCTION

The rapid expansion in the epidemiology of eosinophilic esophagitis (EoE) is being documented, along with cumulative research assessing environmental exposures associated with EoE and susceptibility due to genetic variants.

AREAS COVERED

Incidence rates for EoE of 5-10 new cases per 100,000 inhabitants annually have shown an increase in recent reports of up to 20 in some countries; the highest prevalence being reported for Europe and North America, where EoE now affects more than 1 out of 1,000 people. EoE has been shown to be associated with several disorders, Th2-mediated atopies being the most common. Patients with EoE exhibit increased frequency of asthma, allergic rhinitis and eczema, and EoE has been considered as a late component of the atopic march. Risk variants in TSLP, CAPN14 and LRCC32 genes, among others, have all been related to EoE, and interact with prenatal and early life exposure potentially modifying abundance and composition of gut microbiome. Dysregulated interactions between bacteria and mucosal immunity emerge as leading causes of EoE.

EXPERT OPINION

The expanding epidemiology of EoE, the resources needed and subsequent increasing healthcare costs require additional effort to optimize cost-effective management and unveil mechanisms that enhance the development of future preventive strategies.

Gastroesophageal reflux disease in pediatric esophageal atresia: Assessment of clinical symptoms and pH-impedance data

BACKGROUND

Esophageal atresia (EA) is the most common congenital anomaly of the gastrointestinal tract. Gastroesophageal reflux disease (GERD) is a frequent and lifelong problem in these patients. GERD can be asymptomatic and the incidence of esophageal gastric and intestinal metaplasia (Barrett’s esophagus) is increased in adults with EA compared with the general population. Timely and accurate diagnosis of GERD is important to reduce long-term problems and this may be achieved by pH-impedance testing.

AIM

To assess symptoms and pH-impedance data in children after EA, in order to identify their specific features of GERD.

METHODS

This study was conducted from November 2017 to February 2020 and involved 37 children who had undergone EA via open surgical repair (51.35% boys, 48.65% girls; age range: 1-14 years, median: 4.99 years). GERD diagnosis was made based on multichannel intraluminal impedance/pH study and two groups were established: EA without GERD, n = 17; EA with GERD, n = 20. A control group was established with 66 children with proven GERD (68.18% boys, 31.82% girls; median age: 7.21 years), composed of a nonerosive reflux disease (referred to as NERD) group (n = 41) and a reflux esophagitis group (n = 25). Upper gastrointestinal endoscopy with a mucosal esophageal biopsy was performed on all patients.

RESULTS

The most frequently observed symptom in EA patients with GERD and without GERD was cough (70% and 76.5% respectively). The number of patients with positive symptom association probability in the EA groups was significantly larger in the EA without GERD group (P = 0.03). In the control reflux esophagitis group, prevalence of gastrointestinal symptoms was significantly higher than in the NERD group (P = 0.017). For both EA groups, there was strong correlation with index of proximal events (IPE) and total proximal events (EA with GERD: 0.96, P < 0.001; EA without GERD: 0.97, P < 0.001) but level of IPE was significantly lower than in GERD patients without any surgical treatment (P < 0.001). Data on distal mean nocturnal baseline impedance were significantly different between the EA with GERD group (P < 0.001) and the two control groups but not between EA without GERD and the two control groups.

CONCLUSION

Mean nocturnal baseline impedance may have diagnostic value for GERD in EA children after open surgical repair. IPE might be an additional parameter of pH-impedance monitoring.

Low gestational age is associated with less anastomotic complications after open primary repair of esophageal atresia with tracheoesophageal fistula

BACKGROUND

The aim of this study was to evaluate anastomotic complications after primary one-staged esophageal atresia (EA) repair relating to the patients` gestational age (GA).

METHODS

Retrospective data analyses of patients who underwent closure of tracheoesophageal fistula (TEF) and primary esophageal anastomosis from 01/2007 to 12/2018 in two pediatric surgical centers. Exclusion of EA other than Gross type C, long-gap EA, minimal invasive or staged approach. Postoperative complications during the first year of life were assessed. Associated malformations, the incidence of infant respiratory distress syndrome (IRDS) and intraventricular bleeding were analyzed.

RESULTS

Inclusion of 75 patients who underwent primary EA repair. Low GA was associated with significantly lower incidence of anastomotic complications (p = 0.019, r = 0.596, 95% CI 0.10-0.85). Incidence of anastomotic leakage (0% vs. 5.5%; p = 0.0416), recurrent TEF (0% vs. 5.5%; p = 0.0416) und anastomotic stricture (0% vs. 14.5%; p = 0.0019) was significantly lower in patients < 34 gestational weeks. Incidence of IRDS (55% vs. 0%; p < 0.0001) and intraventricular bleeding (25% vs. 3.6%; p = 0.0299) was significantly higher in patients < 34 gestational weeks.

CONCLUSIONS

Despite prematurity-related morbidity, low GA did not adversely affect surgical outcome after primary EA repair. Low GA was even associated with a better anastomotic outcome indicating feasibility and safety of primary esophageal reconstruction.
