Esophageal atresia: long-term morbidities in adolescence and adulthood

Posture and Physical Activity Levels of Parents of Children With Esophageal Atresia: A Comparative Study

BACKGROUND

The aim of this study was to evaluate posture and physical activity of parents of children with Esophageal atresia (EA) and compare them with parents of healthy children.

METHODS

The study included 20 children with EA aged 2-6 years and their parents as study group, and 20 healthy children aged 2-6 years and their parents as control group. The New York Posture Rating Test was used to assess posture, and the International Physical Activity Questionnaire-Short Form was used to assess physical activity of parents.

RESULTS

Children in groups were similar in terms of age, gender and weight (p > 0.05). Parents in groups were similar in terms of age, height, weight, educational level and economic status (p > 0.05). Parents in the study group had higher postural impairment (p = 0.01). There was no significant difference between parents in term of physical activity score (p = 0.07). Although not significantly different, 70% (n = 14) of study group were found to be inactive compared to 35% (n = 7) of control group.

CONCLUSION

In conclusion, the posture of parents of children with EA was more affected than parents of healthy children, and both groups were similar in terms of physical activity, but parents of children with EA had more inactive lifestyle.

Preservation of the azygos vein versus ligation of the azygos vein during primary surgical repair of congenital esophageal atresia

BACKGROUND

Esophageal atresia is one of the most common life-threatening congenital malformations and is defined as an interruption in the continuity of the esophagus with or without fistula to the trachea or bronchi. Definitive treatment is surgical ligation of the fistula if present and esophageal end-to-end anastomosis of the two pouches, thereby reconstructing the continuity of the esophagus. During this procedure, the surgeon may choose to either ligate or preserve the azygos vein, a major draining vein for the esophagus and surrounding structures, but no definitive consensus on the matter exists.

OBJECTIVES

To assess the benefits and harms of preservation of the azygos vein versus ligation of the azygos vein during primary surgical repair of congenital esophageal atresia.

SEARCH METHODS

We identified trials from the Cochrane Gut Specialized Register, Cochrane Central Register of Controlled Trials (CENTRAL) via Ovid Evidence-Based Medicine Reviews Database (EBMR), MEDLINE, Embase, and CINAHL (Cumulative Index to Nursing and Allied Health Literature). We also conducted a search of ClinicalTrials.gov, LILACS, Science Citation Index Expanded and Conference Proceedings Citation Index - Science (Web of Science), and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP). We searched all databases from their inception to 22 May 2024, with no restriction on language of publication.

SELECTION CRITERIA

We included randomized clinical trials (RCTs) assessing preservation of the azygos vein versus ligation of the azygos vein during primary surgical repair of congenital esophageal atresia in infants less than three months of age.

DATA COLLECTION AND ANALYSIS

Pairs of two review authors independently screened titles and abstracts, screened relevant full-text reports, and identified RCTs for inclusion. We recorded the selection process in a PRISMA flow diagram. We assessed the risk of bias of the included studies (using RoB 2) and the certainty of the evidence (using the GRADE approach) according to the Cochrane Handbook for Systematic Reviews of Interventions. We contacted the study authors if data were missing or unclear.

MAIN RESULTS

Six trials met the inclusion criteria, including 390 participants in total. We were able to assess all our primary outcomes: all-cause mortality, serious adverse events, and anastomosis leakage, as well as two of our three secondary outcomes: sepsis or mediastinitis and esophageal stricture. However, none of the six trials assessed recurrent tracheoesophageal fistula. All trials had either some concerns or high risk of bias, and the certainty of the evidence for all outcomes was either low or very low. Meta-analyses showed that preservation of the azygos vein may result in a large reduction in mortality (risk ratio (RR) 0.44, 95% confidence interval (CI) 0.26 to 0.73; low-certainty evidence), serious adverse events (RR 0.33, 95% CI 0.21 to 0.50; very low-certainty evidence), and anastomosis leakage (RR 0.44, 95% CI 0.26 to 0.76; low-certainty evidence) when compared to ligation of the azygos vein in neonates undergoing primary surgical repair of congenital esophageal atresia. Meta-analysis of our secondary outcomes showed that preservation of the azygos vein may result in a large reduction in mediastinitis or sepsis (RR 0.34, 95% CI 0.21 to 0.53; very low-certainty evidence). Esophageal stricture was only reported in two studies with 114 participants. The effects on esophageal stricture were unclear (RR 0.75, 96% CI 0.35 to 1.63; very low-certainty evidence), but the evidence is very uncertain.

AUTHORS' CONCLUSIONS

Current evidence suggests that preserving the azygos vein during primary surgical repair for esophageal atresia may result in large reductions in overall mortality, serious adverse events, anastomosis leakage, and sepsis or mediastinitis. No included data suggested that routine ligation of the azygos vein was beneficial. However, all the evidence was of low to very low certainty. Further research is still warranted as the results of this review may not be applicable to all newborns with congenital esophageal atresia.

Feeding difficulties, food intake, and growth in children with esophageal atresia

Objectives

Challenges regarding feeding difficulties and nutrition in children with esophageal atresia (EA) have been sparsely studied. The aim of this study was to explore parent-reported feeding difficulties in children with EA by applying Montreal Children's Hospital-Feeding Scale (MCH-FS), and to further explore associations between feeding difficulties and clinical factors, growth and nutritional intake.

Methods

Parents of EA children born between 2012 and 2017 were invited. Clinical data were collected from medical records. In a prospective cohort-study parent-reported feeding difficulties (by MCH-FS) were reported at two assessments, and at the second assessment, dietary data were collected by using the 24-h food-recall method.

Results

Out of 55 eligible participants, we evaluated 53 children at median age of 1.6 years (Q1:Q3 1.0:2.9) (first assessment) and 38 at median age of 4.2 years (Q1:Q3 1.0:2.9) (second assessment). Feeding difficulties were reported by 34% and 31% of the parents, respectively, but no particular profile of concerns could be identified. Children's energy intake and weight-for-age were correlated with feeding difficulties (MCH-FS total score) (p < 0.02).

Conclusion

Parent-reported feeding difficulties were identified in one-third of children with EA and related to low energy intake and low weight-for-age, but not to clinical factors. This implies that feeding difficulties must be screened for during follow-up in all EA children and may facilitate early detection of challenges and intervention if needed.

Single-cell analysis reveals the spatial-temporal expression of genes associated with esophageal malformations

Understanding the molecular mechanisms of congenital diseases is challenging due to their occurrence within specific developmental stages. Esophageal malformations are examples of such conditions, characterized by abnormalities in the development of esophagus during embryogenesis. These developmental malformations encompass a range of anomalies, including esophageal atresia, and tracheoesophageal fistula. Here, we investigated the preferential expression of 29 genes that are implicated in such malformations and their immediate interactome (a total of 67 genes). We conducted our analyses across several single-cell atlases of embryonic development, encompassing approximately 150,000 cells from the mouse foregut, 180,000 cells from human embryos, and 500,000 cells from 24 human organs. Our study, spanning diverse mesodermal and endodermal cell populations and early developmental stages, shows that the genes associated with esophageal malformations show their highest cell-type specific expression in lateral plate mesoderm cells and at the developmental stage of E8.75-E9.0 days. In human embryos, these genes show a significant cell-type specific expression among subpopulations of epithelial cells, fibroblasts and progenitor cells including basal cells. Notably, members of the forkhead-box family of transcription factors, namely FOXF1, FOXC1, and FOXD1, as well as the SRY-box transcription factor, SOX2, demonstrate the most significant preferential expression in both mouse and human embryos. Overall, our findings provide insights into the temporal and cellular contexts contributing to esophageal malformations.

Graft dilatation and Barrett's esophagus in adults after gastric pull-up and jejunal interposition for long-gap esophageal atresia

BACKGROUND

Esophageal replacement (ER) with gastric pull-up (GPU) or jejunal interposition (JI) used to be the standard treatment for long-gap esophageal atresia (LGEA). Changes of the ER grafts on a macro- and microscopic level however, are unknown.

AIM

To evaluate long-term clinical symptoms and anatomical and mucosal changes in adolescents and adults after ER for LGEA.

METHODS

A cohort study was conducted including all LGEA patients ≥ 16 years who had undergone GPU or JI between 1985-2003 at two tertiary referral centers in the Netherlands. Patients underwent clinical assessment, contrast study and endoscopy with biopsy. Data was collected prospectively. Group differences between JI and GPU patients, and associations between different outcome measures were assessed using the Fisher's exact test for bivariate variables and the Mann-Whitney U-test for continuous variables. Differences with a P-value < 0.05 were considered statistically significant.

RESULTS

Nine GPU patients and eleven JI patients were included. Median age at follow-up was 21.5 years and 24.4 years, respectively. Reflux was reported in six GPU patients (67%) vs four JI patients (36%) (P = 0.37). Dysphagia symptoms were reported in 64% of JI patients, compared to 22% of GPU patients (P = 0.09). Contrast studies showed dilatation of the jejunal graft in six patients (55%) and graft lengthening in four of these six patients. Endoscopy revealed columnar-lined esophagus in three GPU patients (33%) and intestinal metaplasia was histologically confirmed in two patients (22%). No association was found between reflux symptoms and macroscopic anomalies or intestinal metaplasia. Three GPU patients (33%) experienced severe feeding problems vs none in the JI group. The median body mass index of JI patients was 20.9 kg/m2 vs 19.5 kg/m2 in GPU patients (P = 0.08).

CONCLUSION

The majority of GPU patients had reflux and intestinal metaplasia in 22%. The majority of JI patients had dysphagia and a dilated graft. Follow-up after ER for LGEA is essential.

Developing balloon dilatation sizing guidance for anastomotic stricture dilatation following oesophageal atresia repair

PURPOSE

To develop guidance for the selection of balloon catheter size when performing an oesophageal dilatation for a stricture post oesophageal atresia repair.

METHODS

This was a single centre retrospective study at a paediatric tertiary centre. Dilatations were performed between 2015 and 2020. All dilatations were performed under general anaesthesia using balloon catheters under fluoroscopic guidance. Outliers were excluded using ROUT method and descriptive analysis was calculated to 1SD or IQR depending on the normality of data distribution.

RESULTS

97 patients underwent 341 dilatations. Median age was 19 months (37 weeks corrected gestation-17 years), median weight was 10.7 kg (2.6-72 kg). Balloon catheter sizes ranged from 6-8 mm to 18-20 mm. There was strong correlation between weight and balloon size (r = 0.8, p < 0.0001). There were 2 perforations (0.6%), both diagnosed intra-operatively and treated conservatively. From the results, weight recommendations were created for each balloon size.

CONCLUSION

Fluoroscopic balloon dilatation is a safe and effective method to treat anastomotic stricture following oesophageal atresia repair. Previous studies have shown correlation between patient weight and oesophageal diameter. We propose guidance for using an appropriate balloon size based on patient's weight with the aim to reduce complication.

Bacterial Colonization of the Lower Airways in Children With Esophageal Atresia

BACKGROUND

Esophageal atresia (EA) is most often accompanied by some degree of tracheomalacia (TM), which negatively influences the airway by ineffective clearance of secretions. This can lead to lower airway bacterial colonization (LABC), which may cause recurrent respiratory tract infections (RTIs). This study aims to evaluate the prevalence and specific pathogens of LABC in EA patients.

METHODS

A 5-year retrospective single-site cohort study was conducted including all EA patients that had undergone an intraoperative bronchoalveolar lavage (BAL) during various routine surgical interventions. Concentrations of greater than 10 cfu were considered evidence of LABC.

RESULTS

We recruited 68 EA patients, of which 12 were excluded based on the exclusion criteria. In the remaining 56 patients, a total of 90 BAL samples were obtained. In 57% of the patients, at least 1 BAL sample was positive for LABC. Respiratory symptoms were reported in 21 patients at the time of the BAL, of which 10 (48%) had LABC. Haemophilus influenzae (14%) and Staphylococcus aureus (16%) were most frequently found in the BAL samples. The number of respiratory tract infections and the existence of a recurrent fistula were significantly associated with LABC ( P = 0.008 and P = 0.04, respectively).

CONCLUSIONS

This is the first study showing that patients with EA have a high prevalence of bacterial colonization of the lower airways which may be a leading mechanism of severe and recurrent respiratory complications.

Oral Viscous Budesonide in Children With Eosinophilic Esophagitis After Repaired Esophageal Atresia: A Clinical Trial

OBJECTIVES

A high prevalence of eosinophilic esophagitis (EoE) has been reported in children with repaired esophageal atresia (EA). Topical steroids proved to be an effective and safe therapy in EoE, although not approved in pediatrics. We report the results of the first clinical trial of oral viscous budesonide (OVB) performed in children with EoE after repaired esophageal atresia (EoE-EA).

METHODS

This open-label, single-arm, phase 2 clinical trial with randomized pharmacokinetic sampling, was conducted at the Bambino Gesù Children's Hospital between September 2019 and June 2021. EoE-EA patients received an age-banded dose of OVB twice daily for 12 weeks and were endoscopically evaluated. The primary endpoint was the rate of patients achieving histological remission. Secondary endpoints included clinical and endoscopic benefit after treatment, and safety assessments.

RESULTS

Eight consecutive EA-EoE patients were enrolled (median age 9.1 years, interquartile range 5.5). Of these, 5 received 0.8 mg and 3 received 1.0 mg twice daily of OVB. Histological remission was obtained in all but 1 patient (87.5%). The clinical score showed significant improvement at the end of treatment in all patients. No endoscopic features of EoE were found after treatment. No treatment-emergent adverse event occurred.

CONCLUSION

OVB is an effective, safe, and well-tolerated formulation of budesonide for use in pediatric patients with EoE-EA.

Esophageal Surveillance Practices in Esophageal Atresia Patients: A Survey by the Eastern Pediatric Surgery Network

INTRODUCTION

Endoscopic surveillance guidelines for patients with repaired esophageal atresia (EA) rely primarily on expert opinion. Prior to embarking on a prospective EA surveillance registry, we sought to understand EA surveillance practices within the Eastern Pediatric Surgery Network (EPSN).

METHODS

An anonymous, 23-question Qualtrics survey was emailed to 181 physicians (surgeons and gastroenterologists) at 19 member institutions. Likert scale questions gauged agreement with international EA surveillance guideline-derived statements. Multiple-choice questions assessed individual and institutional practices.

RESULTS

The response rate was 77%. Most respondents (80%) strongly agree or agree that EA surveillance endoscopy should follow a set schedule, while only 36% claimed to perform routine upper GI endoscopy regardless of symptoms. Many institutions (77%) have an aerodigestive clinic, even if some lack a multi-disciplinary EA team. Most physicians (72%) expressed strong interest in helping develop evidence-based guidelines.

CONCLUSIONS

Our survey reveals physician agreement with current guidelines but weak adherence. Surveillance methods vary greatly, underscoring the lack of evidence-based data to guide EA care. Aerodigestive clinics may help implement surveillance schedules. Respondents support evidence-based protocols, which bodes well for care standardization. Results will inform the first multi-institutional EA databases in the United States (US), which will be essential for evidence-based care.

LEVEL OF EVIDENCE

This is a prognosis study with level 4 evidence.

Sex-specific percentiles for bodyweight and height in children born with esophageal atresia: a registry-based analysis 2001-2021

BACKGROUND

Esophageal atresia (EA) is a rare malformation with a wide range of co-morbidity and associated malformations impairing weight gain and growth. The aim of this study was to calculate specific percentiles for body weight and height for children born with esophageal atresia according to sex from birth to the age of 6 years, accounting for prematurity and presence of congenital heart disease (CHD).

METHODS

Data was extracted from an anonymized voluntary national registry for patients born with esophageal atresia between 2001 and 2021, from birth until the age of six years. Missing values were imputed using a multiple imputation approach. In premature infants, chronological age was corrected for gestational week until the age of one year. The impact of sex and additional congenital heart disease on weight gain and growth was analysed using quartile regression models.

RESULTS

In total, 1812 examinations of 485 patients were considered and 1232 examinations of 301 patients were finally included. Most data was available for children at birth and during the first year of life. Body weight was imputed for 3.3% and height for 12.5% of examinations. The mean body weight-for-age and length-for-age at birth according to gestational age was lower in EA patients and median body weight developed along the tenth percentile compared to the general population. Median height-for-age was at the 50th percentile during the first months of life, before crossing to lower percentiles before the age of one year. CHD had an additional negative impact on growth and weight gain, especially during the first year of life.

CONCLUSIONS

Children with EA had a reduced bodyweight and -height compared to the general population. Therefore, specific percentile curves are helpful to evaluate growth and development. Especially during the first year of life, particular attention is necessary and complications leading to a reduced calorie intake should be treated without delay to promote timely development and growth. Cardiac co-morbidities may further compromise weight gain in these patients, implying that such patients should be under even closer surveillance.

Long-Term Outcomes and Health-Related Quality of Life in a Swiss Patient Group with Esophageal Atresia

INTRODUCTION

 Surgical treatment of esophageal atresia (EA) has markedly improved, allowing the focus to shift from short-term complications and mortality to long-term complications and quality of life. Health-related quality of life (HRQoL) is variable and reported to range from reduced to unimpaired in patients with repaired EA. We assessed the HRQoL, determined the prevalence of long-term complications and their possible impact on the HRQoL in patients who had correction of EA in Switzerland. Further, we also investigated in the general well-being of their parents.

MATERIALS AND METHODS

 Patients with EA repair in Switzerland between 1985 and 2011 were enrolled. Long-term complications were assessed by enquiring disease-related symptoms, standardized clinical examinations, and analysis of radiographs. HRQoL was inquired using different validated questionnaires (KIDSCREEN-27, World Health Organization [WHO]-5, and Gastrointestinal Quality of Life Index [GIQLI]). Patients were grouped according to their age. In underage patients, general well-being of the parents was assessed using the WHO-5 questionnaire.

RESULTS

 Thirty patients were included with a mean age of 11.3 ± 5.7 years. Long-term complications were present in 63% of all patients. HRQoL in underage patients was comparable to the provided reference values and rated as good, while adult patients reported a reduced HRQoL. The presence of gastroesophageal reflux disease symptoms was associated with reduced HRQoL in underage patients. Parents of underage patients stated a good general well-being.

CONCLUSION

 Long-term complications among patients with repair of EA in Switzerland are common. HRQoL in underage patients is good and general well-being of their parents is unimpaired. Adult patients reported a reduced HRQoL, consistent with other reports. As long-term complications may manifest only later in life, a structured follow-up of patients with an EA repair during childhood and adolescence is needed.

Traumatic stress, mental health, and quality of life in adolescents with esophageal atresia

INTRODUCTION

We aimed to investigate QoL in EA patients in relation to comparison groups and to clinical factors including experienced traumatic stress.

MATERIAL AND METHODS

Adolescents with EA in Norway born between 1996 and 2002 were included. Clinical assessment and patient's characteristics were collected. Quality of life (PedsQL), traumatic stress (IES-13) and mental health (SDQ-20) were compared to groups of healthy controls, children with acute lymphoblastic leukemia (ALL) and kidney transplanted children (TX).

RESULTS

68 EA adolescents participated. Total scores for PedsQL were not different from the healthy group and ALL patients, but significantly better than the TX patients. The subscale for physical performance was significantly lower than in healthy adolescents, and nine (17%) patients had scores ≤70 indicating reduced health status. Five EA adolescents (12%) had mental health scores suggesting a psychiatric disorder, and six (9%) reported high traumatic stress scores with a significant correlation to days on ventilator in the neonatal period. The strongest predictors for quality of life among EA adolescents were self-reported mental health, posttraumatic stress and GERD symptoms.

CONCLUSION

Scores for Quality of life in the EA group are good except for subscale for physical performance. Symptoms of posttraumatic stress, mental strain and gastroesophageal reflux are predictors of reduced QoL.

Longitudinal Health Status and Quality of Life After Esophageal Atresia Repair

OBJECTIVES

To longitudinally evaluate self-reported and proxy-reported health status (HS) and quality of life (QoL) of school-aged children born with esophageal atresia (EA).

METHODS

We obtained Pediatric Quality of Life Inventory (HS) and DUX-25 (QoL) questionnaires from children born with EA between 1999 and 2011 at 8 and/or 12 years old. Children completed self-reports during neuropsychological assessments in a prospective longitudinal follow-up program. Parents filled out proxy-reports at home. Total and subscale scores were evaluated longitudinally and compared with sex-specific reference norms.

RESULTS

In total, 110 participants (62% boys) were included. Self-reported HS improved significantly between 8 and 12 years for both boys (mean difference [md] 4.35, effect size [ES] 0.54, P = 0.009) and girls (md 3.26, ES 0.63, P = 0.004). Proxy-reported HS tended to improve over time, while self-reported and proxy-reported QoL tended to decline. Self-reported HS at 8 years was below normal for both boys (md -5.44, ES -0.35, P < 0.001) and girls (md -7.61, ES -0.32, P < 0.001). Girls' self-reported QoL was below normal at 8 (md -5.00, ES -0.18, P = 0.019) and 12 years (md -10.50, ES -0.26, P = 0.001). Parents reported normal HS at both ages, whereas they rated the QoL of their daughters below normal at 12 years (md -10.00, ES -0.16, P = 0.022). All above results are total scores.

CONCLUSIONS

Self-reported and proxy-reported HS of children with EA improved between 8 and 12 years, while their QoL tended to decline. We recommend to consider HS and QoL as two separate concepts and to measure both simultaneously and longitudinally when evaluating the burden of disease.

Patient-driven healthcare recommendations for adults with esophageal atresia and their families

BACKGROUND

Adults with esophageal atresia (EA) require a multidisciplinary follow-up approach, taking into account gastroesophageal problems, respiratory problems and psychosocial wellbeing. Too little is known about the full scope of these individuals' healthcare needs. We aimed to map all medical and psychosocial needs of adults with EA and their family members, and to formulate healthcare recommendations for daily practice.

METHODS

A qualitative study was performed, using data from recorded semi-structured interviews with two focus groups, one consisting of adult patients with EA (n = 15) and one of their family members (n = 13). After verbatim transcription and computerized thematic analysis, results were organized according to the International Classification of Functioning, Disability and Health. Ethical approval had been obtained.

RESULTS

Healthcare needs were described through 74 codes, classified into 20 themes. Most important findings for patients included the impact of gastrointestinal and pulmonary problems on daily life, long-term emotional distress of patients and parents and the need of a standardized multidisciplinary follow-up program during both child- and adulthood.

CONCLUSION

The focus groups revealed numerous physical and mental health problems, as well as social difficulties, that require attention from different healthcare providers. We have formulated several healthcare recommendations that physicians may use in long-term follow-up.

A thematic analysis exploring the psychological well-being of adults born with esophageal atresia

BACKGROUND

Living with a rare and chronic health condition can have a significant impact on psychological well-being and mental health. There is a growing understanding that Esophageal Atresia (EA), a rare birth defect often accompanied by a Trachea-Esophageal Fistula (TEF), is a complex health condition that requires lifelong medical attention beyond pediatric care into adulthood. Given the reciprocal relationship between one's physical and psychological well-being, the aim of this study was to develop a better understanding of the mental health of adults born with EA/TEF.

METHODS

An international online survey was designed and disseminated in collaboration with an EA/TEF patient charity. The qualitative data was analyzed using a reflexive and inductive Thematic Analysis to explore the research question "How can being born with EA/TEF affect psychological well-being in adulthood?"

RESULTS

A total of 92 adults born with EA/TEF completed the online survey from 11 different counties. Five themes were generated during the analysis: 'Negative Experience with Healthcare Professionals', 'The Perception of Surgical Scars', 'The Psychosocial Consequences of Dysphagia', 'The Legacy of Medical Trauma', and 'Resilience in the Face of Adversity'.

CONCLUSION

The results indicated that adults born with EA/TEF might face emotional challenges that can negatively affect their psychological well-being and mental health. It was also found that some adults born with EA/TEF demonstrate resilience through positive reappraisal of adverse experiences. The current study suggests that a multidisciplinary approach to the care of adults born with EA/TEF is necessary and directions for future research are discussed.

Evaluation of Gastroesophageal Reflux Disease 1 Year after Esophageal Atresia Repair: Paradigms Lost from a Single Snapshot?

OBJECTIVE

To analyze the findings of both multichannel intraluminal impedance with pH (MII-pH) and endoscopy/histopathology in children with esophageal atresia at age 1 year, according to current recommendations for the evaluation of gastroesophageal reflux disease (GERD) in esophageal atresia.

STUDY DESIGN

We retrospectively reviewed both MII-pH and endoscopy/histopathology performed in 1-year-old children with esophageal atresia who were followed up in accordance with international recommendations. Demographic data and clinical characteristics were also reviewed to investigate factors associated with abnormal GERD investigations.

RESULTS

In our study cohort of 48 children with esophageal atresia, microscopic esophagitis was found in 33 (69%) and pathological esophageal acid exposure on MII-pH was detected in 12 (25%). Among baseline variables, only the presence of long-gap esophageal atresia was associated with abnormal MII-pH. Distal baseline impedance was significantly lower in patients with microscopic esophagitis, and it showed a very good diagnostic performance in predicting histological changes.

CONCLUSIONS

Histological esophagitis is highly prevalent at 1 year after esophageal atresia repair, but our results do not support a definitive causative role of acid-induced GERD. Instead, they support the hypothesis that chronic stasis in the dysmotile esophagus might lead to histological changes. MII-pH may be a helpful tool in selecting patients who need closer endoscopic surveillance and/or benefit from acid suppression.

Eosinophilic esophagitis in esophageal atresia: Tertiary care experience of a "selective" approach for biopsy sampling

BACKGROUND

A high prevalence (9.5-30%) of eosinophilic esophagitis (EoE) in patients with esophageal atresia (EA) has been reported. The application of the EoE criteria to EA patients might be problematic. To date, only studies using a "routine" biopsy approach, even in asymptomatic patients, have been performed. The aim of the study was to establish the prevalence of EoE among symptomatic EA patients (EA/EoE group) without anastomotic stricture (AS) and to compare their characteristics with those of EoE patients from general population (EoE group).

METHODS

From 2005 to 2018, we reviewed charts of children with EA and EoE. "Selective" biopsy approach only in EA children without AS and/or endoscopic feature of EoE was performed. Characteristics of EA/EoE and EoE groups were compared.

RESULTS

Among 370 EA and 118 EoE, 15 EA/EoE patients were detected (4.0% of EA patients). Male predominance and a high prevalence of allergy without differences between EA/EoE and EoE groups was observed. EA/EoE children were significantly younger (p < 0.0001). PPI-responder patients were significantly more prevalent in EA/EoE group (p = 0.045).

CONCLUSION

Our data confirm that EA patients are at high risk for developing EoE. High incidence, early onset, and high prevalence of PPI-responders might suggest that esophageal motility disorders interact to increase propensity to EoE in EA patients. However, our study also suggests that overdiagnosis of EoE may occur in EA and that adapted criteria for EoE diagnosis should be developed for EA patients.

Nutritional Status in Adolescents with Esophageal Atresia

OBJECTIVES

To examine factors that may affect nutritional status in adolescents with esophageal atresia.

STUDY DESIGN

Anthropometric measurements, blood samples, pH measuring, mapping of dysphagia with a modified Easting Assessment Test questionnaire, 4-day dietary record, and a semistructured interview about eating habits and nutrition counseling were performed in a cross-sectional cohort of adolescents with esophageal atresia.

RESULTS

Out of 102 eligible patients, 68 (67%) participated. The median height-for-age Z score was -0.6 (-4.6 to 1.8). Ten (15%) were classified as stunted (height-for-age Z score <-2). Fourteen (21%) were overweight. More than two-thirds reported symptoms of dysphagia (Easting Assessment Test score ≥3) and avoided specific foods. Forty-eight (71%) completed the 4-day dietary record, which showed daily intake of energy below age-appropriate recommendations. One-third reported an energy intake below their estimated basal metabolic rate. Only 24% had received counselling from a dietitian.

CONCLUSIONS

Adolescents with a history of esophageal atresia have growth below reference values and energy intake below recommendations. Energy intake and its relation to stunting needs to be further studied in patients with esophageal atresia.

The Impact of Congenital Esophageal Atresia on the Family Functioning

PURPOSE

Most of the research in the field of esophageal atresia (EA) is focused on diagnostic problems and surgery. There is scarce literature addressing the impact of EA on the lives of families of patients. The aim of this paper is to investigate whether the presence of underlying associated malformations, disease-specific feeding problems and prematurity would have a significant influence on the family of a child after surgical repair of EA.

DESIGN AND METHODS

The study sample consisted of 73 participants who were parents of children after surgery of EA. The impact of EA on families was assessed using an Authors-Designed Questionnaire (ADQ) to collect medical and sociodemographic background data as well as standardized questionnaire: the PedsQL™ Family Impact Module (PedsQL-FIM).

RESULTS

The presence of cardiac impairment significantly (p = 0.037) affects the functioning of the family in the emotional domain. The coexistence of skeletal impairment seems to have the greatest impact on the functioning of the family, three statistically significant correlations have been demonstrated: (p = 0.021) - in the social domain, (p = 0.009) - in the cognitive domain and (p = 0.023) - in the domain of communication. The families of patients with tracheoesophageal fistula (TEF) had the statistically lower (p < 0.05) score of functioning in the emotional domain than those with children without TEF.

CONCLUSION

Feeding problems and the presence of associated anomalies significantly affect the functioning of the family of the child with EA.

Agreement between mothers', fathers', and children's' ratings on health-related quality of life in children born with esophageal atresia - a German cross-sectional study

BACKGROUND

Esophageal atresia (EA) is a rare congenital malformation, which is characterized by the discontinuity of the esophagus. We investigated the agreement between mothers', fathers', and children's' ratings on health-related quality of life (HRQOL) in children born with EA. We aimed to broaden the understanding of subjective experiences of HRQOL from different perspectives. We hypothesized that the agreement between mother and father ratings would be high, whereas the agreement between child and mother ratings as well as child and father ratings would show more substantial differences.

METHODS

We obtained data from 40 families (23 mother-father dyads of children aged 2-7 years and 17 mother-father-child triads of children and adolescents aged 8-18 years) with children born with EA, who were treated in two German hospitals. HRQOL was measured using the generic PedsQL™ questionnaires and the condition-specific EA-QOL© questionnaires. We calculated intraclass coefficients and performed one-way repeated measures ANOVAs to analyze differences for each domain as well as for the total scores.

RESULTS

Intraclass correlation coefficients (ICCs) indicated a strong agreement (≥.80) between mother and father reports of children's HRQOL for both generic and condition-specific measurements. The ICCs for the generic HRQOL for mother/father-child-dyads revealed only fair to good agreement, whereas ICCs for condition-specific HRQOL showed high agreement for mother-child and father-child-agreement. Analyses of Covariance revealed differences in mother/father-child agreement in the generic domain School, both parents reporting lower HRQOL scores than the children themselves. Fathers reported significantly higher scores in the condition-specific domain Social than their children.

CONCLUSIONS

Results showed that mothers' and fathers' reports corresponded to each other. Nonetheless, these reports might not be interchangeably used because mother-child and father-child agreement showed differences. Children might know the best on how they feel, and parent proxy-report is recommended when reasons such as young age, illness, or cognitive impairments do not allow to ask the child. But parent-report - no matter if reported by mother or father - should only be an additional source to broaden the view on the child's health status and well-being. The current study contributes to a better understanding of the complex family relationships involved when parenting a child born with EA.

The prevalence and role of coping strategies in the nutritional intake of children born with esophageal atresia: a condition-specific approach

This study describes results of a condition-specific approach to the assessment of coping strategies in nutritional intake situations used by children with esophageal atresia. One hundred three families of children 2-17 years old with esophageal atresia participated (94% response rate). Following standardized focus groups with 30 families, nine coping items were developed, reflecting nine different coping strategies in nutritional intake situations. The coping items were pilot tested by 73 new families and evaluated for feasibility, validity, and reliability. The families also completed a validated condition-specific quality-of-life questionnaire for children with esophageal atresia, which included the scale Eating-Quality-of-life. Data were analyzed using descriptives, between-group analysis, and Spearman's rho (P < 0.05). Altogether, the coping items were feasible, valid, and reliable. Items reflecting problem-focused strategies revealed that 89% of 2-17 years old 'recognized their responsibility' and managed nutritional intake problems on their own, 79% 'tried to solve their feeding problems' testing different solutions, 79% took a 'confronting approach' to do what peers did in eating situations, and 54% 'sought other people's support'. Items reflecting emotion-focused strategies showed that 86% of the children 'accepted' their feeding difficulties, 68% 'reappraised feeding difficulties into positive outcomes' such as to eat only when food tasted good. Moreover, 63% of the children 'avoided' nutritional intake situations, 29% 'expressed worry or fear' when faced with these situations, while 25% 'distanced' themselves from eating problems by hiding or throwing away food. The children's use of coping strategies were mostly related to the existence of digestive symptoms (P < 0.05). Positive and negative coping strategies were identified. Of particular note was a correlation cluster of the so-called disengagement strategies 'avoidance', 'expression of emotional concerns' and 'distancing'. These strategies were negatively correlated with Eating-Quality-of-Life. Conversely, taking a 'confronting approach' correlated positively with Eating-Quality-of-life (P < 0.05). Hence, most children with esophageal atresia employ various coping strategies in nutritional intake situations. A good Eating-Quality-of-life may be positively affected by treating digestive morbidity and encouraging children to take an active approach to their eating problems rather than using disengagement coping.

Neonatal factors predictive for respiratory and gastro-intestinal morbidity after esophageal atresia repair

BACKGROUND

Esophageal atresia is a major congenital foregut anomaly. Affected patients often suffer from respiratory and gastro-intestinal morbidity. The objective of this study is to identify possible neonatal predictive factors contributing to a long-term complicated clinical course in patients after repair of esophageal atresia.

METHODS

A total of 93 patients born between 1993 and 2013, with esophageal atresia and surviving the neonatal period were included in this retrospective study. A complicated clinical course was defined as the occurrence of ≥1 of these complications: severe gastro-esophageal reflux, esophageal stricture requiring dilatations, need for tube feeding for >100 days, severe tracheomalacia, severe chronic respiratory disease and death. We used linear models with a binomial distribution to determine risk factors for gastro-intestinal or respiratory complicated evolution and a backward stepwise elimination procedure to reduce models until only significant variables remained in the model. Multinomial logistic regression was used to assess risk factors for different evolutions of complication. Model parameter estimates were used to calculate odds ratios for significant risk factors.

RESULTS

Fifty-seven patients (61%) had a complicated clinical course in the first year of life and 47 (51%) had a complicated evolution during years 1-6. In the first year, prematurity was a significant factor for complicated gastro-intestinal (OR 2.84) and respiratory evolution (OR 2.93). After 1 year, gastro-intestinal morbidity in childhood was associated with VACTERL association (OR 12.2) and a complicated first year (OR 36.1). Respiratory morbidity was associated with congenital heart disease (OR 12.9) and a complicated first year (OR 86.9). Multinomial logistic regression showed that prematurity (p = 0.018) and VACTERL association (p = 0.003) were significant factors of complications.

CONCLUSION

Prematurity is an important predictive factor for a complicated clinical course in early life. A complicated first year often predicts a complicated clinical course in childhood. These risk factors may be helpful in counseling of parents in the neonatal period.

The assessment of the esophageal motility of children with esophageal disorders by the detailed observation of the pH-multichannel intraluminal impedance waveform and baseline impedance: screening test potential

BACKGROUND

The present study aimed to evaluate whether the detailed observation of pH/MII waveforms and the analysis of baseline impedance (BI) values could detect esophageal dysmotility in pediatric patients with esophageal disorders.

PATIENTS AND METHODS

Eleven patients with congenital esophageal disorder in whom pH/MII was conducted from April 2011 to June 2015, were enrolled in this study. The diagnoses of the patients were as follows: postoperative esophageal atresia (EA), n = 6; esophageal achalasia (EAch), n = 4; and congenital esophageal stenosis (CES), n = 1. The characteristics of the pH/MII waveform, pathological GERD, BI value, and the average BI value of the 2 distal channels (distal BI; DBI) were analyzed in each disorder.

RESULTS

Two EA (33%) patients and one EAch (25%) patient were diagnosed with GERD. The mean DBI values of the EA, EAch and CES patients was 912 ± 550, 2153 ± 915 and 1392 Ω, respectively. The EA patients showed consistently low DBI values. One CES patient and two infantile EAch patients showed postprandial prolonged low DBI values. Whereas, the pH/MII waveforms of the adolescent EAch patients were difficult to interpret due to their extremely low BI values.

CONCLUSIONS

The present study demonstrated that the detailed observation of the pH/MII waveforms in all channels and the analysis of BI were useful for evaluating esophageal motility in children with congenital esophageal disorders. In particular, infantile patients with EAch showed DBI findings that were distinct from those of adult EAch patients. Considering the difficulty of performing esophageal manometry in young children, the detailed observation of the pH/MII waveform may help in the diagnosis of esophageal dysmotility in children.

Health-related quality of life experiences in children and adolescents born with esophageal atresia: A Swedish-German focus group study

BACKGROUND

Esophageal atresia (EA) is a rare malformation of the esophagus, which needs surgical treatment. Survival rates have reached 95%, but esophageal and respiratory morbidity during childhood is frequent. Child and parent perspectives and cultural and age-specific approaches are fundamental in understanding children's health-related quality of life (HRQoL) and when developing a pediatric HRQoL questionnaire. We aimed to increase the conceptual and cross-cultural understanding of condition-specific HRQoL experiences among EA children from Sweden and Germany and investigate content validity for an EA-specific HRQoL questionnaire.

METHODS

Eighteen standardized focus groups (FGs) with 51 families of EA children aged 2-17 years in Sweden (n = 30 families) and Germany (n = 21 families) were used to explore HRQoL experiences, which were content analyzed into HRQoL domains. The Swedish HRQoL domains were analyzed first and used as framework to evaluate HRQoL content reported in the German FGs. HRQoL experiences were then categorized as physical, social, and emotional HRQoL burden or resource.

RESULTS

One thousand nine hundred eight HRQoL statements were recorded. All nine EA-specific HRQoL domains identified in the Swedish FGs (eating, social relationships, general life issues, communication, body issues, bothersome symptoms, confidence, impact of medical treatment, and additional difficulties due to concomitant anomalies) were recognized in the FGs held in Germany, and no additional EA-specific HRQoL domain was found. The HRQoL dimensions referenced physical burden (n = 655, 34.5%), social burden (n = 497, 26.0%), social resources (n = 303, 15.9%), emotional burden (n = 210, 11.0%), physical resources (n = 158, 8.3%), and emotional resources (n = 85, 4.5%).

CONCLUSION

This first international FG study to obtain the EA child and his or her parents' perspective on HRQoL suggests Swedish-German qualitative comparability of the HRQoL domains and content validity for a cross-cultural EA-specific HRQoL questionnaire. EA children make positive and negative HRQoL experiences, but prominently related to physical and social burden, which underlines appropriate follow-up care and future research.

Transitions in care from pediatric to adult general surgery: Evaluating an unmet need for patients with anorectal malformation and Hirschsprung disease

BACKGROUND

The provision of timely and comprehensive transition of care from pediatric to adult surgical providers for patients who have undergone childhood operations remains a challenge. Understanding the barriers to transition from a patient and family perspective may improve this process.

METHODS

A cross-sectional survey was conducted of patients with a history of anorectal malformation (ARM) or Hirschsprung Disease (HD) and their families. The web-based survey was administered through two support groups dedicated to the needs of individuals born with these congenital abnormalities. Categorical variables were compared using Chi-squared and Fisher's exact test with Student's t test and ANOVA for continuous variables.

RESULTS

A total of 118 surveys were completed (approximately 26.2% response). The average age of patients at time of survey was 12.3years (SD 11.6) with 64.5% less than 15years old. The primary diagnosis was reported for 78.8% patients and included HD (29.0%), ARM (61.3%), and cloaca (9.7%). The average distance traveled for ongoing care was 186.6miles (SD 278.3) with 40.9% of patients traveling ≥30miles; the distance was statistically significantly greater for patients with ARM (p<0.001). With regards to ongoing symptoms, 44.1% experience constipation, 40.9% experience diarrhea, and approximately 40.9% require chronic medication for management of bowel symptoms; only 3 respondents (3.2%) reported fecal incontinence. The majority of patients, 52.7% reported being seen by a provider at least twice per year and the majority continued to be followed by a pediatric provider, consistent with the majority of the cohort being less than 18years of age. Conversations with providers regarding transitioning to an adult physician had occurred in fewer than 13% of patients. The most commonly cited barrier to transition was the perception that adult providers would be ill-equipped to manage the persistent bowel symptoms.

CONCLUSION

Patients undergoing childhood procedures for ARM or HD have a high prevalence of ongoing symptoms related to bowel function but very few have had conversations regarding transitions in care. Early implementation of transitional care plans and engagement of adult providers are imperative to transitions and may confer long-term health benefits in this patient population.

How to Care for Patients with EA-TEF: The Known and the Unknown

PURPOSE OF REVIEW

Guidelines were recently published highlighting why esophageal atresia (EA) patients are prone to complication risks, and the need for long-term follow-up. In this review, we will focus on how to investigate and treat potential complications, as well as the pros and cons of different investigative and treatment modalities, and what areas continue to need further research.

RECENT FINDINGS

EA patients are at high risk for gastroesophageal reflux and esophageal strictures, and the sequela that result. Extraintestinal manifestations of gastroesophageal reflux disease (GERD) can appear similar to other pathologic diagnoses commonly found in EA patients, such as congenital stricture, eosinophilic esophagitis, esophageal dysmotility, tracheomalacia, recurrent fistula, aspiration, etc. Therefore, it is important to have a standardized way to monitor for these issues. pH impedance allows for detection of nonacid reflux and the height of reflux, which are important in correlating symptoms with reflux episodes. A multidisciplinary approach is beneficial in evaluating and monitoring EA patients in the long term.

Development and pilot-testing of a condition-specific instrument to assess the quality-of-life in children and adolescents born with esophageal atresia

The survival rate of children with esophageal atresia has today reached 95%. However, children are at risk of chronic morbidity related to esophageal and respiratory dysfunction, and associated anomalies. This study describes the pilot testing of a condition-specific health-related quality-of-life instrument for children with esophageal atresia in Sweden and Germany, using a patient-derived development approach consistent with international guidelines. Following a literature review, standardized focus groups were conducted with 30 Swedish families of children with esophageal atresia aged 2-17 years. The results were used for item generation of two age-specific pilot questionnaire versions. These were then translated from Swedish into German with considerations of linguistic and semantical perspectives. The 30-item pilot questionnaire for children aged 2-7 years was completed by 34 families (parent report), and the 50-item pilot questionnaire for children aged 8-17 years was completed by 52 families (51 child report, 52 parent report), with an overall response rate of 96% in the total sample. Based on predefined psychometric criteria, poorly performing items were removed, resulting in an 18-item version with three domains (Eating, Physical health and treatment, Social isolation and stress,) for children aged 2-7 years and a 26-item version with four domains (Eating, Social relationships, Body perception, and Health and well-being) for children aged 8-17 years. Both versions demonstrated good internal consistency reliability and acceptable convergent and known-groups validity for the total scores. The study identified specific health-related quality-of-life domains for pediatric patients with esophageal atresia, highlighting issues that are important for follow-up care. After field testing in a larger patient sample, this instrument can be used to enhance the evaluation of pediatric surgical care.

Postoperative Complications and Functional Outcome after Esophageal Atresia Repair: Results from Longitudinal Single-Center Follow-Up

BACKGROUND

Esophageal atresia (EA) and tracheoesophageal fistula (TEF) represent major therapeutic challenges, frequently associated with serious morbidities following surgical repair. The aim of this longitudinal study was to assess temporal changes in morbidity and mortality of patients with EA/TEF treated in a tertiary-level center, focusing on postoperative complications and their impact on long-term gastroesophageal function.

METHODS

One hundred nine consecutive patients with EA/TEF born between 1975 and 2011 were followed for a median of 9.6 years (range, 3-27 years). Comparative statistics were used to evaluate temporal changes between an early (1975-1989) and late (1990-2011) study period.

RESULTS

Gross types of EA were A (n = 6), B (n = 5), C (n = 89), D (n = 7), and E (n = 2). Seventy (64.2%) patients had coexisting anomalies, 13 (11.9%) of whom died before EA correction was completed. In the remaining 96 infants, surgical repair was primary (n = 66) or delayed (n = 25) anastomosis, closure of TEF in EA type E (n = 2), and esophageal replacement with colon interposition (n=2) or gastric transposition (n=1). Long-gap EA was diagnosed in 23 (24.0%) cases. Postoperative mortality was 4/96 (4.2%). Overall survival increased significantly between the two study periods (42/55 vs. 50/54; P = 0.03). Sixty-nine (71.9%) patients presented postoperatively with anastomotic strictures requiring a median of 3 (range, 1-15) dilatations. Revisional surgery was required for anastomotic leakage (n = 5), recurrent TEF with (n = 1) or without (n=9) anastomotic stricture, undetected proximal TEF (n = 4), and refractory anastomotic strictures with (n = 1) or without (n = 2) fistula. Normal dietary intake was achieved in 89 (96.7%) patients, while 3 (3.3%) remained dependent on gastrostomy feedings. Manometry showed esophageal dysmotility in 78 (84.8%) infants at 1 year of age, increasing to 100% at 10-year follow-up. Fifty-six (60.9%) patients suffered from dysphagia with need for endoscopic foreign body removal in 12 (13.0%) cases. Anti-reflux medication was required in 43 (46.7%) children and 30 (32.6%) underwent fundoplication. The rate of gastroesophageal reflux increased significantly between the two study periods (29/42 vs. 44/50; P = 0.04). Twenty-two (23.9%) cases of endoscopic esophagitis and one Barrett's esophagus were identified.

CONCLUSIONS

Postoperative complications after EA/TEF repair are common and should be expertly managed to reduce the risk of long-term morbidity. Regular multidisciplinary surveillance with transitional care into adulthood is recommended in all patients with EA/TEF.

Anastomotic Strictures after Esophageal Atresia Repair: Incidence, Investigations, and Management, Including Treatment of Refractory and Recurrent Strictures

Improved surgical techniques, as well as preoperative and postoperative care, have dramatically changed survival of children with esophageal atresia (EA) over the last decades. Nowadays, we are increasingly seeing EA patients experiencing significant short- and long-term gastrointestinal morbidities. Anastomotic stricture (AS) is the most common complication following operative repair. An esophageal stricture is defined as an intrinsic luminal narrowing in a clinically symptomatic patient, but no symptoms are sensitive or specific enough to diagnose an AS. This review aims to provide a comprehensive view of AS in EA children. Given the lack of evidence-based data, we critically analyzed significant studies on children and adults, including comments on benign strictures with other etiologies. Despite there is no consensus about the goal of the luminal diameter based on the patient's age, esophageal contrast study, and/or endoscopy are recommended to assess the degree of the narrowing. A high variability in incidence of ASs is reported in literature, depending on different definitions of AS and on a great number of pre-, intra-, and postoperative risk factor influencing the anastomosis outcome. The presence of a long gap between the two esophageal ends, with consequent anastomotic tension, is determinant for stricture formation and its response to treatment. The cornerstone of treatment is endoscopic dilation, whose primary aims are to achieve symptom relief, allow age-appropriate capacity for oral feeding, and reduce the risk of pulmonary aspiration. No clear advantage of either balloon or bougie dilator has been demonstrated; therefore, the choice is based on operator experience and comfort with the equipment. Retrospective evidences suggest that selective dilatations (performed only in symptomatic patients) results in significantly less number of dilatation sessions than routine dilations (performed to prevent symptoms) with equal long-term outcomes. The response to dilation treatment is variable, and some patients may experience recurrent and refractory ASs. Adjunctive treatments have been used, including local injection of steroids, topical application of mitomycin C, and esophageal stenting, but long-term studies are needed to prove their efficacy and safety. Stricture resection or esophageal replacement with an interposition graft remains options for AS refractory to conservative treatments.

Impedance Testing in Esophageal Atresia Patients

Esophageal atresia patients are predisposed to gastroesophageal reflux as a result of the altered esophageal anatomy and motility. These patients experience significant morbidity from gastroesophageal reflux. As a result, an effective way to diagnose and monitor for reflux is crucial. pH-metry is able to quantify acid burden, ensure that acid suppression is adequate during long-term follow-up, and correlate acid reflux to symptoms. pH with impedance is additionally able to detect non-acid reflux as well as volume clearance, both of which also correlate with patient symptoms. It is also able to correlate extra-gastrointestinal symptoms to reflux, which may help guide treatment. If complications associated with uncontrolled reflux are identified, aggressive reflux management is necessary, oftentimes requiring surgical intervention.

Long-term morbidity in adolescents and young adults with surgically treated esophageal atresia

PURPOSE

To investigate the long-term morbidity of surgically treated esophageal atresia (EA) in adolescents and young adults and establish whether these long-term morbidities are affected by the type of EA.

PATIENTS AND METHODS

We reviewed the medical records, including backgrounds and associated conditions, of 69 long-term survivors of EA, aged >15 years. The long-term morbidities included neurodevelopmental abnormality, nutritional impairment (short height <-2SD, low BMI <18.5), subjective symptoms, and musculoskeletal deformities. Comparisons of the results were made between Gross A-type EA (n = 6) and Gross C-type EA (n = 63).

RESULTS

All patients underwent esophageal anastomosis without esophageal replacement. Cardiac anomalies and long gap were present in 26 and 18%, respectively. Esophageal dilatation, fundoplication, and aortopexy were performed in 40, 34, and 18%, respectively. The incidence of long gap and esophageal stenosis was higher in Gross A-type EA than in Gross C-type EA. The long-term morbidities included neurodevelopmental abnormality (13%), nutritional impairment (62%: as short height in 34% and as low BMI in 46%), subjective symptoms (14%), and musculoskeletal deformities (59%). There were no differences in the long-term morbidities between Gross A and Gross C.

CONCLUSIONS

The incidence of the long-term morbidities is high in adolescents and young adults, regardless of the type of EA. Early detection of morbidity is important to improve the long-term outcomes of EA.

Insufficient Body Weight of Adults Born With Esophageal Atresia

OBJECTIVES

Impaired growth has been reported in children born with esophageal atresia (EA). Their nutritional fate at adulthood remains uncertain though. Our objectives were to determine the body mass index (BMI) of adult patients with EA followed up from 2009 to 2011 in the EA clinic of a university-affiliated hospital in Quebec (Canada), and investigate characteristics associated with underweight.

METHODS

The 40 adult patients with EA attending the clinic were invited to participate. Height and weight were measured and BMI calculated. Patients with BMI < 18.5 kg/m were deemed underweight. Patients' characteristics were obtained, including digestive symptoms and compensatory eating behaviors. Nonparametric tests were used to compare the proportion of underweight among patients with EA with that found in the Quebec population and the characteristics between patients with EA deemed underweight and those with BMI ≥ 18.5 kg/m.

RESULTS

The final sample included 16 women and 21 men, ages 18 to 44 years. Mean BMI was 21.3 ± 4.9 kg/m and 24.3% had BMI < 18.5 kg/m, which is higher than in the Quebec adult population (2.5%, P < 0.001). Compared with patients with EA having BMI ≥ 18.5 kg/m, underweight patients had more often experienced failure to thrive during their adolescence (55.6% vs 7.4%, P = 0.006), and reported severe postprandial fullness (62.5% vs 21.4%, P = 0.040), the need to eat slowly (87.5% vs 46.4%; P = 0.045), and severe difficulties to swallow dry solid foods (50.0% vs 14.3%, P = 0.054).

CONCLUSIONS

Insufficient body weight is prevalent in this sample of adult patients with EA and could result from digestive symptoms. Follow-up with a gastroenterologist and nutritional counseling should be considered for adult patients with EA.

Dysphagia in children with repaired oesophageal atresia

Dysphagia is a common problem in children with repaired oesophageal atresia (OA). Abnormalities in the oropharyngeal and oesophageal phase have hardly been studied. The aims of this study were to assess the prevalence of dysphagia in children with repaired OA and to identify and differentiate oral and pharyngeal dysphagia based on videofluoroscopic swallow study (VFSS) findings in a limited number of children in this cohort. Medical records of 111 patients, born between January 1996 and July 2013 and treated at the Radboudumc Amalia Children's Hospital, were retrospectively reviewed. The prevalence of dysphagia was determined by the objective and modified Functional Oral Intake Scale (FOIS) in four age groups. The first performed VFSS of 12 children was structurally assessed. The prevalence of dysphagia was 61 of 111 patients (55 %) in age group <1 year. In age group 1-4, 5-11 and 12-18 years, the prevalence of dysphagia decreased from 54 of 106 (51 %) patients to 11 of 64 (17 %) and 5 of 24 (21 %) patients. The 12 VFSS's reviews revealed oral dysphagia in 36 % and pharyngeal dysphagia in 75 %.

CONCLUSIONS

This study highlights dysphagia as an important problem in different age groups of children with repaired OA. Furthermore, our study shows the presence of oropharyngeal dysphagia in this population. This study emphasizes the need to standardize the use of objective dysphagia scales, like the modified FOIS, to provide a careful follow-up of children with repaired OA.

WHAT IS KNOWN

• Prevalence of dysphagia in children with repaired oesophageal atresia varies widely (ranges from 45 to 70 %) in literature. • Oral, pharyngeal and oesophageal dysphagia require different treatment approaches. What is New: • We determined dysphagia based on functional oral intake and provide an overview of change in dysphagia prevalence and severity over time in children with repaired OA. • Our study shows that dysphagia, including oropharyngeal dysphagia, is highly prevalent in young children with repaired OA and improves with time.

Gastroesophageal reflux and congenital gastrointestinal malformations

Although the outcome of newborns with surgical congenital diseases (e.g., diaphragmatic hernia; esophageal atresia; omphalocele; gastroschisis) has improved rapidly with recent advances in perinatal intensive care and surgery, infant survivors often require intensive treatment after birth, have prolonged hospitalizations, and, after discharge, may have long-term sequelae including gastro-intestinal comorbidities, above all, gastroesophageal reflux (GER). This condition involves the involuntary retrograde passage of gastric contents into the esophagus, with or without regurgitation or vomiting. It is a well-recognized condition, typical of infants, with an incidence of 85%, which usually resolves after physiological maturation of the lower esophageal sphincter and lengthening of the intra-abdominal esophagus, in the first few months after birth. Although the exact cause of abnormal esophageal function in congenital defects is not clearly understood, it has been hypothesized that common (increased intra-abdominal pressure after closure of the abdominal defect) and/or specific (e.g., motility disturbance of the upper gastrointestinal tract, damage of esophageal peristaltic pump) pathological mechanisms may play a role in the etiology of GER in patients with birth defects. Improvement of knowledge could positively impact the long-term prognosis of patients with surgical congenital diseases. The present manuscript provides a literature review focused on pathological and clinical characteristics of GER in patients who have undergone surgical treatment for congenital abdominal malformations.

Clinical relevance of esophageal baseline impedance measurement: just an innocent bystander

OBJECTIVE

The clinical relevance of esophageal baseline impedance (BI) remains to be determined. In the present study, we explored the impact of gastroesophageal reflux disease (GERD) and esophageal dysmotility on BI.

METHODS

A total of 18 children with esophageal atresia, 26 children with GERD, and 17 controls prospectively underwent esophagogastroduodenoscopy and pH-impedance monitoring. BI was measured in both proximal and distal esophagus. Gastroesophageal reflux (GER) and bolus transit indicators were defined according to published criteria.

RESULTS

Patients with esophageal atresia showed significantly lower proximal and distal BI values (952 [716-1811] Ω; 895 [284-1189] Ω; respectively) compared with those with GERD (3015 [2368-3975] Ω; 2231 [1770-3032] Ω, P < 0.001 and <0.001, respectively) and controls (3699 [3194-4358] Ω; 3522 [2927-3994] Ω, P < 0.001 and <0.001, respectively). Using linear regression, proximal BI strongly correlated with total bolus transit time (r(2) = 0.61, P < 0.001) and bolus presence time (BPT; r(2) = 0.63, P < 0.001). Distal BI weakly correlated with acid exposure time (r(2) = 0.16, P < 0.01) and longstanding reflux episodes (r(2) = 0.17, P < 0.01), and strongly correlated with total bolus transit time (r(2) = 0.53, P < 0.001) and BPT (r(2) = 0.58, P < 0.001). By logistic regression, BPT predicted low proximal BI values (odds ratio [OR] 1.052; P < 0.05), whereas both GER indicators (acid exposure time: OR 1.56, P < 0.05; longstanding reflux episodes: OR 2.8, P < 0.05) and BPT (OR 1.66, P < 0.01) predicted low distal BI values.

CONCLUSIONS

Along the length of esophagus, both bolus transit variables and GER significantly affect BI. This suggests that BI may merely mirror phenomena occurring within the esophageal lumen or wall, limiting its value as a discrete clinical entity to replace variables already used for assessing both GERD and esophageal dysmotility.

The Surgical Correction of Congenital Deformities: The Treatment of Diaphragmatic Hernia, Esophageal Atresia and Small Bowel Atresia

BACKGROUND

More than half of all congenital deformities can be detected in utero. The initial surgical correction is of paramount importance for the achievement of good long-term results with low surgical morbidity and mortality.

METHODS

Selective literature review and expert opinion.

RESULTS

Congenital deformities are rare, and no controlled trials have been performed to determine their optimal treatment. In this article, we present the prenatal assessment, treatment, and long-term results of selected types of congenital deformity. Congenital diaphragmatic hernia (CDH) affects one in 3500 live-born infants, while esophageal atresia affects one in 3000 and small-bowel atresia one in 5000 to 10,000. If a congenital deformity is detected and its prognosis can be reliably inferred from a prenatal assessment, the child should be delivered at a specialized center (level 1 perinatal center). The associated survival rates are 60-80% after treatment for CDH and well over 90% after treatment for esophageal or small-bowel atresia. Despite improvements in surgical correction over the years, complications and comorbidities still affect 20-40% of the treated children. These are not limited to surgical complications in the narrow sense, such as recurrence, postoperative adhesions and obstruction, stenoses, strictures, and recurrent fistulae, but also include pulmonary problems (chronic lung disease, obstructive and restrictive pulmonary dysfunction), gastrointestinal problems (dysphagia, gastro-esophageal reflux, impaired intestinal motility), and failure to thrive. Moreover, the affected children can develop emotional and behavioral disturbances. Minimally invasive surgery in experienced hands yields results as good as those of conventional surgery, as long as proper selection criteria are observed.

CONCLUSION

Congenital deformities should be treated in recognized centers with highly experienced interdisciplinary teams. As no randomized trials of surgery for congenital deformities are available, longitudinal studies and registries will be very important in the future.

Contractile profile of esophageal and gastric fundus strips in experimental doxorubicin-induced esophageal atresia

Esophageal atresia (EA) is characterized by esophageal and gastric motility changes secondary to developmental and postsurgical damage. This study evaluated the in vitro contractile profile of the distal esophagus and gastric fundus in an experimental model of EA induced by doxorubicin (DOXO). Wistar pregnant rats received DOXO 2.2 mg/kg on the 8th and 9th gestational days. On day 21.5, fetuses were collected, sacrificed, and divided into groups: control, DOXO without EA (DOXO-EA), and DOXO with EA (DOXO+EA). Strips from the distal esophagus and gastric fundus were mounted on a wire myograph and isolated organ-bath system, respectively, and subjected to increasing concentrations of carbamylcholine chloride (carbachol, CCh). The isolated esophagus was also stimulated with increasing concentrations of KCl. In esophagus, the concentration-effect curves were reduced in response to CCh in the DOXO+EA and DOXO-EA groups compared to the control group (P<0.05). The maximum effect values (E_max) for DOXO+EA and DOXO-EA were significantly lower than control (P<0.05), but the half-maximal effective concentration (EC₅₀) values were not significantly different when the three groups were compared (P>0.05). In response to KCl, the distal esophagus samples in the three groups were not statistically different with regard to E_max or EC₅₀ values (P>0.05). No significant difference was noted for EC₅₀ or E_max values in fundic strips stimulated with CCh (P>0.05). In conclusion, exposure of dams to DOXO during gestation inhibited the contractile behavior of esophageal strips from offspring in response to CCh but not KCl, regardless of EA induction. The gastric fundus of DOXO-exposed offspring did not have altered contractile responsiveness to cholinergic stimulation.

Esophageal atresia and transitional care--step 1: a systematic review and meta-analysis of the literature to define the prevalence of chronic long-term problems

BACKGROUND

Esophageal atresia (EA) is a rare congenital anomaly with high infantile survival rates. The aim of this study was to outline the prevalence of common long-term problems associated with EA repair in patients older than 10 years of age.

DATA SOURCES

Original papers were identified by systematic searching of MEDLINE and EMBASE databases from January 1993 to July 2014. Fifteen articles (907 EA patients) met inclusion criteria.

CONCLUSIONS

This is the first systematic review aiming to quantify the prevalence of the long-term problems associated with EA. The main active medical conditions (pooled estimated prevalence) identified were the following: dysphagia (50.3%), gastroesophageal reflux disease with (40.2%) or without (56.5%) histological esophagitis, recurrent respiratory tract infections (24.1%), doctor-diagnosed asthma (22.3%), persistent cough (14.6%), and wheeze (34.7%). The prevalence of Barrett's esophagus (6.4%) was 4 and 26 times higher than the adult (1.6%) and pediatric (.25%) general populations. Adult and pediatric practitioners should focus on how to develop effective long-term follow-up and transitional care for these patients.

Ethical aspects of care in the newborn surgical patient

This article places focus on three main subjects that are all related to the ethical aspects of care of newborns undergoing major surgical interventions. The first concerns the communication between the surgeon, as a representative of the treatment team, and the parents. The second is the way to handle new developments in neonatal surgery. The third issue covers several aspects of the ethical decision-making process with regard to forgoing life support in surgical neonates. These issues will be discussed on the basis of two clinical case reports.
