A nationwide analysis of clinical outcomes among newborns with esophageal atresia and tracheoesophageal fistulas in the United States

Repair of Type C Tracheo-esophageal Fistula/Esophageal Atresia With or Without Trans Anastomotic Tube: A Pilot Randomized Controlled Trial

BACKGROUND

The use of trans anastomotic feeding tube (TAFT) during the repair of Esophageal atresia/Tracheo-esophageal fistula (EA/TEF) aims to enhance outcomes by enabling early feeding, reducing the requirement for parenteral nutrition, and reducing complications such as anastomotic leak by stenting the anastomosis. However, TAFT's benefits and drawbacks are debated due to conflicting reports. Thus, we conducted a prospective pilot randomized control trial to elucidate the impact of TAFT on postoperative outcomes and the potential benefits of avoidance of TAFT.

METHODS

We performed a single-center randomized controlled trial in 53 neonates diagnosed with Type C EA/TEF who were operated on from January 2022 to June 2023. The patients were randomized into TAFT (n = 30) and non-TAFT (n = 23) groups. The patients were followed up for a minimum of 6 months following discharge. The primary objective of the study was to compare the rate of anastomotic leaks following primary repair of EA/TEF in both groups. Secondary objectives included early postoperative outcomes such as the occurrence of anastomotic stricture, time taken to initiate feeding, the time required to reach full feeding, the incidence of brief resolved unexplained events (BRUE) or acute life-threatening events (ALTE), the incidence of gastroesophageal reflux (GER), somatic growth, and all-cause mortality within 30 days post-surgery.

RESULT

The study demonstrated that TAFT placement was associated with a higher incidence of anastomotic leaks (20 % vs 0, p = 0.03). However, there was no difference in the 30-day mortality between both groups. Although the rate of anastomotic strictures and GER was higher in the TAFT group (54.5 % vs 27.8 %, p = 0.08 and 25 % vs 57.1 %, p = 0.076), it did not reach statistical significance. Avoiding TAFT resulted in earlier initiation of enteral feeding (18 vs 22 days, p = 0.002), shorter time to achieve full feeds (15 vs 21 days, p = 0.03), reduced duration of TPN (3 vs 10 days; p = 0.001), improved weight gain at the 2-week follow-up (27.5 vs. 24.4 g/kg/day, p-value = 0.037) and lesser incidence of ALTE/BRUE (11.1 % vs 48 %, p = 0.01) at 6 months.

CONCLUSION

While previous research has covered TAFT's impact on complications such as anastomotic leak, stricture, use of TPN and enteral feed, prospective randomized studies remain limited, and the impact on GER, somatic growth, and occurrence of ALTE/BRUE is still unexplored. This study evaluated the short-term outcomes of EA/TEF in a resource-challenged setting, shedding light on the potential benefits of repair without TAFT such as reduction in the rate of anastomotic leak, earlier feeding, reduced GER, better somatic growth and reduced incidence of ALTE/BRUE.

Birth weight and thoracoscopic approach for patients with esophageal atresia and tracheoesophageal fistula-a retrospective cohort study

BACKGROUND

This study aimed to analyze the results, feasibility and safety of the thoracoscopic approach for patients with esophageal atresia with tracheoesophageal fistula (EA/TEF) depending on the patient's birth weight.

METHODS

The study involved only type C and D EA/TEF. Among the analyzed parameters were the patients' characteristics, surgical treatment and post-operative complications: early mortality, anastomosis leakage, anastomosis strictures, chylothorax, TEF recurrence, and the need for fundoplication or gastrostomy.

RESULTS

145 consecutive newborns underwent thoracoscopic EA with TEF repair. They were divided into three groups-A (N = 12 with a birth weight < 1500 g), B (N = 23 with a birth weight ≥ 1500 g but < 2000 g), and C-control group (N = 110 with a birth weight ≥ 2000 g). Primary one-stage anastomosis was performed in 11/12 (91.7%) patients-group A, 19/23 (82.6%)-group B and 110 (100%)-group C. Early mortality was 3/12 (25%)-group A, 2/23 (8.7%)-group B, and 2/110 (1.8%)-group C and was not directly related to the surgical repair. There were no significant differences in operative time and the following complications: anastomotic leakage, recurrent TEF, esophageal strictures, and chylothorax. There were no conversions to an open surgery. Fundoplication was required in 0%-group A, 4/21 (19.0%)-group B, and 2/108 (1.9%)-group C survivors. Gastrostomy was performed in 1/9 (11.1%)-group A, 3/21 (14.3%)-group B and 0%-group C.

CONCLUSION

In an experienced surgeon's hands, even in the smallest newborns, the thoracoscopic approach may be safe, feasible, and worthy of consideration. Birth weight seems to be not a direct contraindication to the thoracoscopic approach.

Clinical and Biological Perspectives on Noncanonical Esophageal Squamous Cell Carcinoma in Rare Subtypes

Esophageal squamous cell carcinoma (ESCC) remains the most common malignancy of the esophagus worldwide. Environmental and lifestyle exposures such as alcohol and tobacco have been well defined in the pathogenesis of ESCC, acting in concert with cell intrinsic epigenomic, genomic and transcriptomic changes. However, a variety of nonenvironmental etiologies including Fanconi anemia, lichen planus, chronic mucocutaneous candidiasis, esophageal epidermoid metaplasia, epidermolysis bullosa, tylosis, esophageal atresia, and achalasia receive minimal attention despite a high risk of ESCC in these diseases. The goal of this review was to promote clinical recognition and suggest a diagnostic framework for earlier detection of ESCC in patients with these rare diseases. In all the discussed conditions, a change in symptoms should trigger a prompt endoscopic evaluation, and endoscopic surveillance programs with advanced imaging techniques and chromoendoscopy should be considered. Moreover, we leverage the convergence of these diseases on ESCC to identify common mechanisms underlying malignant transformation including aberrant proliferation, mucosal barrier dysfunction, increased inflammation, and genome instability. In this study, we summarize the clinical presentation, pathologic findings, potential screening strategies, and common mechanisms of malignant transformation associated with these rare diseases that drive ESCC.

Worth the Wait? The Impact of Timing of Repair of Esophageal Atresia With Tracheoesophageal Fistula on Outcomes

INTRODUCTION

Infants with esophageal atresia and tracheoesophageal fistula (EA/TEF) are at increased risk for respiratory compromise and gastric perforation until fistula ligation. We sought to describe current practice regarding the timing of EA/TEF repair and hypothesized that age at repair is a predictor of adverse outcomes.

METHODS

The Pediatric Health Information System (PHIS) database was used to identify patients with EA/TEF who underwent fistula ligation and esophago-esophagostomy at US children's hospitals from July 2016-June 2021. Patients with a repair >10 days of age, a long-gap atresia, or H-type fistula were excluded. Comorbidities including prematurity and operative congenital heart disease were noted. Outcomes including anastomotic leak, gastric perforation, and post-operative respiratory failure were assessed for association with age and day of the week of operation.

RESULTS

Among 863 patients that were evaluated, the plurality of operations was on DOL 2 (36%) and 83% were on a weekday (random rate = 71%). Later operations had shorter LOS (p = 0.04) and more recurrent nerve injuries (p = 0.01). Weekend repairs were associated with equivalent outcomes. Gastric perforations occurred in 18 (2.0%) patients; 11 (61%) of these occurred after DOL 2.

CONCLUSIONS

We found no significant differences in outcomes other than more recurrent nerve injury and decreased LOS with EA/TEF repair at older ages. Although repair beyond DOL 2 was safe from a respiratory standpoint, most gastric perforations occurred after this point. In the absence of contraindications or significantly reduced weekend capabilities, we recommend repair of EA/TEF by DOL 2.

Thoracoscopic primary repair is useful for esophageal atresia with tracheoesophageal fistula in neonates with low body weight

PURPOSE

The surgical indication of thoracoscopic primary repair for esophageal atresia with tracheoesophageal fistula is under debate. The current study aimed to investigate the outcome of thoracoscopic primary repair for esophageal atresia with tracheoesophageal fistula in patients weighing < 2000 g and those who underwent emergency surgery at the age of 0 day.

METHODS

The surgical outcomes were compared between patients weighing < 2000 g and those weighing > 2000 g at surgery and between patients who underwent surgery at the age of 0 day and those who underwent surgery at age ≥ 1 day.

RESULTS

In total, 43 patients underwent thoracoscopic primary repair for esophageal atresia with tracheoesophageal fistula. The surgical outcomes according to body weight were similar. Patients who underwent surgery at the age of 0 day were more likely to develop anastomotic leakage than those who underwent surgery at the age of ≥ 1 day (2 vs. 0 case, p = 0.02). Anastomotic leakage was treated with conservative therapy.

CONCLUSION

Thoracoscopic primary repair is safe and useful for esophageal atresia with tracheoesophageal fistula even in newborns weighing < 2000 g. However, emergency surgery at the age of 0 day should be cautiously performed due to the risk of anastomotic leakage.

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.

Treatment courses and outcomes of oesophageal atresia in patients with trisomy 18: a case series of 271 patients from a nationwide database in Japan

OBJECTIVE

To describe characteristics, treatments and clinical outcomes of patients with trisomy 18 and oesophageal atresia, using a nationwide database in Japan.

DESIGN

Descriptive study using a retrospective cohort.

SETTING

A nationwide inpatient database including 90% of hospitals with neonatal intensive care units in Japan.

PATIENTS

Patients hospitalised within a day after birth for both oesophageal atresia and trisomy 18 between July 2010 and March 2020.

INTERVENTIONS

Radical surgery for oesophageal atresia.

MAIN OUTCOME MEASURES

Characteristics, treatment course and outcomes.

RESULTS

Among 271 patients with both oesophageal atresia and trisomy 18, 70 patients underwent radical surgery for oesophageal atresia. Patients who underwent radical surgery were less likely to have severe cardiac anomalies (17% vs 32%; p=0.020), but more likely to undergo cardiac surgery (21% vs 9.5%; p=0.012) than those who did not. The overall in-hospital mortality was lower (54% vs 79%; p<0.001) and the median age at death was higher (210 days vs 39 days; p<0.001) in patients who underwent radical surgery than the others. Postoperative mortality within 30 days after radical surgery was 5.7%. Patients who underwent radical surgery were likely to be discharged to home (50% vs 18%; p<0.001), whereas the age at home discharge (median 314 days vs 216 days; p=0.19) and the requirement for each home treatment did not differ significantly by radical surgery.

CONCLUSION

This study provides information that will aid the clinical decision-making process for patients with oesophageal atresia and trisomy 18. Radical surgery may be a safe and feasible treatment option.

Management and Outcomes of Esophageal Atresia With or Without Tracheo-Esophageal Fistula Over 15 Years in South Africa

INTRODUCTION

To determine the incidence, management and outcomes of esophageal atresia/tracheo-esophageal fistula (EA/TEF) over a 15-y period in South Africa.

METHODS

A retrospective chart review of neonates with EA/TEF presenting at the main tertiary referral hospital in the KwaZulu-Natal province between 2002 and 2017 was conducted. Data collection comprised patient and maternal demographics, clinical presentations, laboratory and radiologic investigations, surgical procedures, and outcomes. A multivariate logistic regression determined the risk factors associated with mortality.

RESULTS

Among 180 neonates, mean (SD) age of diagnosis was four (three) days postnatal with Gross Type C (n = 165, 92%) being the most common and the incidence was one per 10,000 live births. Majority were born term (n = 95, 53%) at peripheral hospitals (n = 167, 93%) with a mean birth weight of 2369 (736) grams. Overall HIV exposure rate was 27% (n = 48). Most (n = 138, 77%) patients presented with established pneumonia, 44% (n = 61) of whom required prolonged (>7 d) ventilator support. The median (IQR) hospital stay was 11 (8-20) d. Overall survival rate was 70% (n = 126). Birth weight <1500 g, life threatening anomalies, ventilation >30 d and postoperative sepsis contributed to mortality.

CONCLUSIONS

Incidence, disease types and presentations were similar to developed countries. Despite advances in technology and neonatal care in Africa, EA/TEF surgical outcomes remain suboptimal likely due to caregivers' inability to care for these infants in disadvantaged socioeconomic circumstances with poor sanitation, etc. Research is needed to identify strategies tailored for disadvantaged communities which may contribute to improved outcomes in the perioperative and postoperative period.

Morbidity and mortality among neonates with esophageal atresia and/or tracheoesophageal fistula in the United States

BACKGROUND

Although rare, esophageal atresia (EA) and/or tracheoesophageal fistula (TEF) can lead to severe morbidity and mortality. A known complication of EA and/or TEF repair is vocal fold motion impairment (VFMI).

OBJECTIVE

To characterize the prevalence of VFMI among repaired EA and/or TEF at a national level and to identify factors associated with in-patient mortality and common clinical endpoints in this population (tracheostomy and gastrostomy tube dependence).

METHODS

This is a retrospective cohort study of inpatient neonate admissions with EA and/or TEF in the 2016 Kids' Inpatient Database (KID). Patients with a history of EA and/or TEF were identified with ICD-10 codes. VFMI prevalence was assessed by observed frequencies and percentages. Clinical endpoints included gastrostomy (G-)tube placement, tracheostomy status, and inpatient mortality. Potential predictors of these three primary outcomes included cardiac anomalies, airway disorders, chromosomal anomalies, surgery within 24 h of admission, prematurity, and low birthweight (LBW). Chi-squared analysis was performed between each parameter and the primary outcomes. Significant associations (p-value<0.05) were further assessed with multivariate logistic regression.

RESULTS

Of 1062 neonates with history of EA and/or TEF, 24 (2.3%) had VFMI. Among this population, 27 patients underwent tracheostomies and 63 required G-tubes. There was a significantly higher likelihood of tracheostomy in patients with VFMI compared to patients without (16.7% versus 2.2%; p < 0.01). After multivariate analysis, birthweight less than 1.5 kg (BW < 1.5 kg; OR = 2.5, 95% CI: 1.03-6.10), extreme prematurity (OR = 7.5, 95% CI: 2.00-28.07), cardiac anomalies (OR = 1.8, 95% CI: 1.01-3.04) and chromosomal anomalies (OR = 4.2, 95% CI: 2.39-7.44) were significantly associated with in-hospital mortality. Bronchopulmonary dysplasia (BPD; OR = 4.7, 95% CI: 1.73-12.78) and BW < 1.5 kg (OR = 2.4, 95% CI: 1.05-5.49) were significant predictors for G-tube status. For tracheostomy, BPD (OR = 15.8, 95% CI: 4.70-52.83) and subglottic stenosis (SS, OR = 11.2, 95% CI: 1.85-68.02) remained significant predictors after multivariate regression.

CONCLUSION

The national prevalence of VFMI among neonates following EA and/or TEF repair was 2.3% and was associated with an increased likelihood of tracheostomy in the KID 2016. Significant predictors of in-hospital mortality were cardiac anomalies, chromosomal anomalies, extreme prematurity, and BW < 1.5 kg. BPD and SS were significant predictors of tracheostomy, and BPD and BW < 1.5 kg were significant predictors for G-tube requirements.

Association between birth location and short-term outcomes for babies with gastroschisis, congenital diaphragmatic hernia and oesophageal fistula: a systematic review

BACKGROUND

Neonatal care is commonly regionalised, meaning specialist services are only available at certain units. Consequently, infants with surgical conditions needing specialist care who are born in non-surgical centres require postnatal transfer. Best practice models advocate for colocated maternity and surgical services as the place of birth for infants with antenatally diagnosed congenital conditions to avoid postnatal transfers. We conducted a systematic review to explore the association between location of birth and short-term outcomes of babies with gastroschisis, congenital diaphragmatic hernia (CDH) and oesophageal atresia with or without tracheo-oesophageal fistula (TOF/OA).

METHODS

We searched MEDLINE, CINAHL, Web of Science and SCOPUS databases for studies from high income countries comparing outcomes for infants with gastroschisis, CDH or TOF/OA based on their place of delivery. Outcomes of interest included mortality, length of stay, age at first feed, comorbidities and duration of parenteral nutrition. We assessed study quality using the Newcastle-Ottawa Scale. We present a narrative synthesis of our findings.

RESULTS

Nineteen cohort studies compared outcomes of babies with one of gastroschisis, CDH or TOF/OA. Heterogeneity across the studies precluded meta-analysis. Eight studies carried out case-mix adjustments. Overall, we found conflicting evidence. There is limited evidence to suggest that birth in a maternity unit with a colocated surgical centre was associated with a reduction in mortality for CDH and decreased length of stay for gastroschisis.

CONCLUSIONS

There is little evidence to suggest that delivery in colocated maternity-surgical services may be associated with shortened length of stay and reduced mortality. Our findings are limited by significant heterogeneity, potential for bias and paucity of strong evidence. This supports the need for further research to investigate the impact of birth location on outcomes for babies with congenital surgical conditions and inform future design of neonatal care systems.

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.

Impact of new dedicated pediatric operating rooms on surgical volume in Africa: Evidence from Nigeria

BACKGROUND

There is a large unmet children's surgical need in low- and middle-income countries (LMICs). This study examines the impact of installing dedicated pediatric operating rooms (ORs) on surgical volume at National Hospital Abuja, a hospital in Abuja, Nigeria.

METHODS

A Non-Governmental Organization installed two pediatric ORs in August 2019. We assessed changes in volume from July 2018 to September 2021 using interrupted time series analysis.

RESULTS

Total surgical volume increased by 13 cases (p = 0.01) in 1-month post-installation, with elective operations making up 85% (p = 0.02) of cases. There was an increase in elective volume by about 1 case per month (p = 0.01) post-installation and the difference between pre-and post-trends was 1.23 cases per month (p = 0.009). The baseline volume of neonatal surgeries increased by 9 cases per month (p < 0.001) post-installation and this difference between pre- and post-trends was statistically significant (p = 0.001). Similarly, one-month post-installation, the cases classified as ASA class >2 increased by 14 (p < 0.001). There was no significant difference between pre-and post-installation mortality rate at about 2% per month.

CONCLUSIONS

There were significant changes in surgical volume after OR installation, primarily composed of elective operations, reflecting an increased capacity to address surgical backlogs and/or perform more specialized surgeries. Despite a significant increase in volume and higher ASA class, there was no significant difference in mortality. This study supports the installation of surgical infrastructure in LMICs to strengthen capacity without increasing postoperative mortality.

Surgical outcome and predictors of neonates with esophageal atresia admitted at Tikur Anbesa Specialized Hospital

BACKGROUND

Esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) is the most common congenital anomaly of the esophagus. This anomaly continues to cause considerable morbidity and mortality in Sub-Saharan Africa, presenting various concerns about how to treat esophageal atresia. Esophageal atresia-related neonatal mortality can be reduced by evaluating the surgical outcome and identifying associated factors.

OBJECTIVE

This study aimed to assess the surgical outcome and identify predictors of neonates with esophageal atresia admitted at Tikur Anbesa specialized hospital.

METHODS

Retrospective crossectional study design was employed on 212 neonates with esophageal atresia who were undergone surgical intervention in Tikur Anbesa specialized hospital. Data were entered into epi data 4.6 and exported to Stata version 16 software for further analysis. A logistic regression model with Adjusted odds ratio (AOR), confidence interval (CI) and p-value <0.05 were used to identify predictors of poor surgical outcome of neonates with esophageal atresia.

RESULT

In this study, 25% of newborns who underwent surgical intervention at TikurAbnbesa specialized hospital had successful surgical outcomes, compared to 75% of neonates with esophageal atresia who had poor surgical outcomes. Significant predictors of the poor surgical outcome of neonates with esophageal atresia were severe thrombocytopenia (AOR = 2.81(1.07-7.34)), timing of surgery (AOR = 3.7(1.34-10.1), aspiration pneumonia (AOR = 2.93(1.17-7.38)) and related abnormalities (AOR = 2.26(1.06-4.82)).

CONCLUSION

The results of this study showed that, when compared to other studies, a substantial percentage of newborn children with esophageal atresia had poor surgical outcomes. Early surgical management, aspiration pneumonia and thrombocytopenia prevention and therapy play a big part in improving the surgical prognosis for newborns with esophageal atresia.

Epidemiologic and clinical characteristics of selected congenital anomalies at the largest Bosnian pediatric surgery tertiary center

Congenital anomalies (CA) are any abnormality present at birth, either structural or functional, that may potentially affect an infant's health, development, and/or survival. There is a paucity of studies on clinical characteristics and outcomes of CA in Bosnia and Herzegovina, mainly due to the lack of a nationwide congenital malformations monitoring system. A 5-year hospital-based study was conducted to determine the prevalence at birth and clinical characteristics of selected major CA in Sarajevo Canton, Bosnia and Herzegovina. Ninety-one CA were observed from 2012 to 2016 (the overall prevalence was 39.6 cases/10,000 live births). The mean age of neonates at diagnosis was 3 days. The gastrointestinal tract was the most commonly affected system (76.9%), with esophageal atresia (EA) being the most frequent (17.6% of all CA). Major CA were more prevalent among preterm infants than term infants (P = .001), particularly in males (61.5% vs. 38.5%; P = .028; M:F ratio was 1.59). Multiple CA were seen in 37.4% of neonates. The overall mortality rate of neonates was 11%, and the median length of hospital stay was 19.8 days. Our study revealed the distribution and clinical patterns of common major CA in the largest tertiary care facility in Bosnia and Herzegovina. It also confirmed a relatively high mortality rate, which requires further efforts to improve the quality of neonatal care in the country.

Short-term and mid-term effects of thoracoscopic repair of esophageal atresia: No anastomotic leaks or conversions to open technique

The frequency rate of esophageal anastomosis leaks after thoracoscopic correction of esophageal atresia (EA) in the current literature is reported as 5.6%-24.7% and a conversion rate of 2%-53%. The objective of this retrospective study was to examine the characteristics of EA and analysis of the safety and efficacy of EA repair with the use of the thoracoscopic approach in a single academic center, as well as risk factors analysis in the context of short-term and mid-term follow-up status. A retrospective analysis of the management of all consecutive newborns affected by EA hospitalized in our department over a period between 2013 and 2022, including preoperative, perioperative, and postoperative management, together with the outcome, complications and long-term follow-up status was performed. A total of 38 patients with a median birth weight of 2,570 g (range; 1,020-3,880) were treated over the study period, including 30/38 (78.9%) with additional congenital anomalies. Overall, 30 patients underwent primary anastomosis of the esophagus and eight underwent a multistaged procedure, with or without an initial ligation of the tracheoesophageal fistula and delayed primary anastomosis. Overall survival for all patients was 0.894 ± 0.050, with a median follow-up of 4.5 years. We noted neither anastomotic leaks nor conversions to open technique in our cohort. Implementation of vancomycin prophylaxis was successful in preventing postoperative central venous access-related infectious complications. At the end of the follow-up, 85% of patients have a Lansky performance score ≥80. Risk factors analysis for length of hospitalization, overall survival, Lansky performance status, and neurological impairment were analyzed. In conclusion, we have found that the outcome of thoracoscopic repair of EA in terms of surgery-dependent morbidity (anastomosis leakage, conversion rate to open surgery), provides benefit to those previously reported in the literature, regardless of the prognostic criteria of the classification system.

The Chinese Mandarin Version of the Esophageal-Atresia-Quality-of-Life Questionnaires for Children and Adolescents: Evaluation of Linguistic and Content Validity

BACKGROUND

After repair of esophageal atresia (EA), children risk digestive and respiratory morbidity, but knowledge of their health-related quality of life (HRQOL) in China is lacking. The EA-QOL questionnaires were developed in Sweden and Germany to evaluate condition-specific HRQOL in children with EA aged 2-7 and 8-17. This study aimed to evaluate the linguistic and content validity of the Chinese Mandarin version of the EA-QOL questionnaires.

METHODS

The procedure was conducted in compliance with international standards, including a forward-backward translation procedure, expert reviews, and cognitive debriefing interviews with 14 Chinese families of children with EA (parents of 8 children aged 2-7/6 children aged 8-17 and their parents).

RESULTS

Following forward-backward translation, minor issues were identified and solved. In interviews, all participants rated all EA-QOL items easy to understand, none expressed negative emotions about them and most described them comprehensive and relevant for EA. Leading from cognitive debriefing, three EA-QOL items in the questionnaire version for children aged 2-7 and three EA-QOL items in the questionnaire version for children aged 8-17 were modified in the Chinese language to improve cultural appropriateness and/or clarity.

CONCLUSION

The Chinese Mandarin version of the EA-QOL questionnaires achieved satisfactory linguistic and content validity. This can help increase focus of HRQOL in research and clinical practice of children with EA in China.

Outcome of esophageal atresia: inborn versus outborn patients

Esophageal atresia (EA) is a rare congenital disease which is usually not of the detected prenatally. Due to the lack of prenatal diagnosis, some newborns with EA are born outside of specialized centers. Nevertheless, centralized care of EA has been proposed, even if a clear volume-outcome association in EA management remains unconfirmed. Furthermore, whether outcomes differ between outborn and inborn patients with EA has not been systematically investigated. Therefore, this single-center, retrospective study aimed to investigate EA management and outcomes with a special focus on inborn versus outborn patients. The following data were extracted from the medical records of infants with EA from 2009 to 2019: EA type, associated anomalies, complications, and long-term outcome. Patients were allocated into inborn and outborn groups. Altogether, 57 patients were included. Five patients were excluded (referral before surgery, loss of data, death before surgery [n = 1], and incorrect diagnosis [diverticulum, n = 1]). Among all patients, the overall survival rate was 96%, with no mortalities among outborn patients. The overall hospitalization period was shorter for outborn patients. The median follow-up durations were 3.8 years and 3.2 years for inborn and outborn patients, respectively. Overall, 15% of patients underwent delayed primary anastomosis (long-gap atresia [n = 4] and other reasons [n = 4]). Early complications included three anastomotic leakages and one post-operative fistula; 28% of patients developed strictures, which required dilatation, and 38% of patients showed relevant gastroesophageal reflux, which required fundoplication, without any differences between the groups. The two groups had comparable low mortality and expected high morbidity with no significant differences in outcome. The outborn group showed nonsignificant trends toward lower morbidity and shorter hospitalization periods, which might be explained by the overall better clinical status.

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.

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.

Long proximal pouch oesophageal atresia with tracheo-oesophageal fistula, a diagnostic dilemma: case report

Background

Oesophageal atresia is a congenital abnormality commonly encountered in neonates. Classification proposed by Gross is the most frequently used. It divides the oesophageal anomalies into five types. Type C—proximal oesophageal atresia and distal tracheo-oesophageal fistula—is the most common. Dafoe and Ross described a rare subtype with a long proximal pouch. Only 11 cases of a long proximal pouch have been reported in the English literature so far. We describe a neonate with long proximal pouch oesophageal atresia with distal tracheo-oesophageal fistula emphasizing the difficulty in arriving at the diagnosis.

Case presentation

A 1-week-old neonate presented with feed intolerance and failure to advance orogastric tube into the stomach. Water soluble upper gastrointestinal tract contrast revealed a blind ending proximal oesophagus at the level of the diaphragm. Gastric volvulus was considered as a diagnosis. Patient underwent a laparotomy where a normal stomach was found. Bubbles were seen coming from the fashioned gastrostomy with each inspiration. This prompted us to consider the possibility of a missed oesophageal atresia with distal tracheo-oesophageal fistula. Diagnosis was confirmed on bronchoscopy and right thoracotomy. The tracheo-oesophageal fistula was ligated and a cervical oesophagostomy and Stamm gastrostomy were performed due to irreparable tear in the long upper pouch.

Conclusion

This rare subtype of long upper pouch oesophageal atresia poses a diagnostic dilemma that can result in delay in the diagnosis and management. This diagnosis should be suspected if the tip of the orogastric/feeding tube is seen to be far below the level of the carina.

Intrinsic Cellular Susceptibility to Barrett's Esophagus in Adults Born with Esophageal Atresia

Simple Summary

We investigated the increased prevalence of Barrett’s esophagus in adults with esophageal atresia. A higher polygenic risk score and disturbances in inflammatory, stress response and oncological pathways upon acid exposure suggest a genetic susceptibility and increased induction of inflammatory processes. Although further research is required to explore this hypothesis, this could be a first-step into selecting patients that are more at risk to develop Barrett’s esophagus and/or esophageal carcinoma. Currently, an endoscopic screening and surveillance program is in practice in our institution for patients born with esophageal atresia, to early detect (pre)malignant lesions. Since recurrent endoscopies can be a burden for the patient, selecting patients by for example genetic susceptibility would allow to only include those at risk in future practice.

Abstract

The prevalence of Barrett’s esophagus (BE) in adults born with esophageal atresia (EA) is four times higher than in the general population and presents at a younger age (34 vs. 60 years). This is (partly) a consequence of chronic gastroesophageal reflux. Given the overlap between genes and pathways involved in foregut and BE development, we hypothesized that EA patients have an intrinsic predisposition to develop BE. Transcriptomes of Esophageal biopsies of EA patients with BE (n = 19, EA/BE); EA patients without BE (n = 44, EA-only) and BE patients without EA (n = 10, BE-only) were compared by RNA expression profiling. Subsequently, we simulated a reflux episode by exposing fibroblasts of 3 EA patients and 3 controls to acidic conditions. Transcriptome responses were compared to the differential expressed transcripts in the biopsies. Predisposing single nucleotide polymorphisms, associated with BE, were slightly increased in EA/BE versus BE-only patients. RNA expression profiling and pathway enrichment analysis revealed differences in retinoic acid metabolism and downstream signaling pathways and inflammatory, stress response and oncological processes. There was a similar effect on retinoic acid signaling and immune response in EA patients upon acid exposure. These results indicate that epithelial tissue homeostasis in EA patients is more prone to acidic disturbances.

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.

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.

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 esophageal atresia in Germany

The aim of this study was to evaluate the outcome of esophageal atresia in Germany in a retrospective observational study of a large cohort. Data from the major health insurance company in Germany, which covers approximately 30% of German patients, were analyzed. All patients born and registered between 2009 and 2013 with a diagnosis of esophageal atresia at first admission to the hospital were included. Mortality was analyzed during the first year of life. We identified 287 patients with esophageal atresia, including 253 with and 34 without tracheoesophageal fistula. Associated anomalies were found in 53.7% of the patients; the most frequent were cardiac anomalies (41.8%), anomalies of the urinary tract (17.4%), and atresia of the colon, rectum, and anus (9.4%). Forty-one patients (14.3%) had a birth weight <1500 g. Seventeen patients (5.9%) died before surgery. Gastrostomy was performed during the index admission in 70 patients (25.9%). The reconstruction of the esophageal passage was performed in 247 patients (93.9%). Forty-eight percent of the patients who underwent an operation required dilatation. The mortality rate in the patients who underwent an operation was 10.4%. These results from Germany correspond to the international results that have been reported. The number of dilatations was in the middle of the range of those reported in the literature; the overall mortality rate was in the upper portion of the range of the international rates. Efforts should be made to establish a clinical registry to measure and improve the quality of care for this and other rare conditions.

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.

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.

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.

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.

The influence of prematurity on neonatal surgical morbidity and mortality

BACKGROUND

As survival rates amongst premature infants have improved, prematurity remains a leading contributor to neonatal surgical morbidity and mortality. This study aims to better assess the influence of prematurity on surgical outcomes.

METHODS

The NSQIP-Pediatric database was used to compare outcomes between preterm and term infants undergoing surgical repair of select congenital anomalies from 2012 to 2017. Prematurity was categorized as extremely preterm (EP) (<29 weeks), very preterm (VP) (29-32 weeks), moderate to late preterm (MLP) (33-36 weeks), and term (≥37 weeks). Significance was determined using Chi-square tests, Fisher exact tests and adjusted logistic regression analysis.

RESULTS

4852 infants were identified with 45 (0.9%) EP, 211 (4.3%) VP, 1492 (30.8%) MLP, and 3104 (64.0%) term. Compared to term, preterm infants have increased odds of surgical morbidity (EP Odds Ratio (OR) 3.2 95% Confidence Interval (CI) 1.6-6.4, VP OR 1.2 95%CI 0.9-1.7, and MLP OR 1.2 95%CI 1.0-1.4). 30-day mortality decreased as neonatal age increased from 22.2% EP to 2.9% term (p < 0.001). Premature populations had higher rates of sepsis, pneumonia, bleeding requiring transfusion and 30-day mortality.

CONCLUSIONS

Prematurity increases morbidity and mortality amongst neonates undergoing surgery. Risk-adjustment for prematurity is needed and premature infants may have unique quality improvement targets.

Predictors of index admission mortality and morbidity in contemporary esophageal atresia patients

BACKGROUND/PURPOSE

The Spitz classification for esophageal atresia with/without tracheoesophageal fistula (EA/TEF) predicts mortality. This study evaluates the contemporary relevance of the Spitz classification and investigates predictors of morbidity.

METHODS

EA/TEF patients born between 1995 and 2018 at two centers were retrospectively reviewed. Clinical variables including sex, prenatal diagnosis, birth weight, prematurity, major congenital heart disease (MCHD), and pre-operative mechanical ventilation (POMV) were collected. Index admission composite morbidity was considered positive if: length-of-stay >90th percentile (139 days), ventilation days >90th percentile (24 days), and/or gastrostomy was used for long-term feeding. Multivariable regression determined predictors of index admission mortality and composite morbidity. A composite morbidity predictive algorithm was created. ROC curves evaluated model discrimination.

RESULTS

Of 253 patients, 13 (5.1%) experienced index admission mortality. Of the patients not suffering mortality, 74 (31.6%) experienced composite morbidity. Only MCHD predicted mortality (p = 0.001); birth weight did not (p = 0.173). There was no difference between the Spitz classification and MCHD alone in predicting mortality risk (p = 0.198); both demonstrated very good discrimination. Prenatal diagnosis, POMV, prematurity, and male sex predicted composite morbidity risk (p < 0.001; p = 0.008; p = 0.009; p = 0.05). An algorithm incorporating these predictors demonstrated good discrimination (AUC = 0.784; 95% CI: 0.724, 0.844).

CONCLUSIONS

The Spitz classification maintains contemporary relevance for mortality risk, though birth weight can be de-emphasized. A new morbidity risk algorithm is proposed for early postnatal counseling.

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.

The value of prophylactic chest tubes in tracheoesophageal fistula repair

PURPOSE

Intraoperative chest tubes (IOCTs) can be placed during esophageal atresia/tracheoesophageal fistula (EA/TEF) repair to control pneumothoraces and detect esophageal leaks, potentially preventing the need for postoperative chest tubes (POCTs). However, data are lacking regarding IOCTs' effect. We hypothesized that IOCT placement would not reduce the risk of POCT placement and would increase hospital length of stay (LOS).

METHODS

This was a single-center case-control study of type C EA/TEF patients repaired at a tertiary referral center between 2006 and 2017. Postoperative complications of patients who received IOCTs (n = 83) were compared to that of patients who did not receive IOCTs (n = 26). Patients were compared via propensity score matching. Additionally, sensitivity analyses excluding low birth weight (LBW) patients and patients undergoing delayed esophageal anastomosis were also performed.

RESULTS

There was no significant difference in rates of pneumothoraces or esophageal leaks between the IOCT and no-IOCT groups, nor were either of these complications detected earlier in the IOCT group. Rates of POCT placement and mortality also did not differ between groups. IOCT patients were associated with increased hospital LOS (28 vs 15.5 days, p < 0.001) and esophageal strictures (30% vs 8%, p = 0.04) requiring a return to the operating room (RTOR).

CONCLUSION

IOCTs did not improve outcomes in EA/TEF repair. IOCTs seem associated with increased LOS and ROTR for esophageal stricture, suggesting that IOCTs may not be beneficial after EA/TEF repair.

Tracheoesophageal fistula in the developing world: are we ready for thoracoscopic repair?

PURPOSE

Tracheoesophageal fistula (TEF) is a bellwether for a country's ability to care for sick newborns. We aim to review the existing literature from low- and middle-income countries in regard to management of those newborns and the possible approaches to improve their outcomes.

METHODS

A review of the existing English literature was conducted with the aim of assessing challenges faced by providers in LMIC in terms of diagnostic, preoperative, operative and post-operative care for TEF patients. We also review the limited literature for performing thoracoscopic repair in the developing world context and suggest methods for introduction of advanced thoracoscopic procedures including techniques for providing anesthesia to these challenging babies.

RESULTS

While outcomes related to technique from LMIC are comparable to the developed world, rates of secondary complications like sepsis and pneumonia are higher. In many areas, repairs are conducted in a staged fashion with minimal utilization of thoracoscopic approach. The paucity of resources creates strain on intraoperative and post-operative management.

CONCLUSION

Clearly, not all developing world contexts are ready to attempt thoracoscopic repair but we outline suggestions for assessing the existing capabilities and a stepwise gradual implementation of advanced thoracoscopy when appropriate.

Nationwide analysis of mortality and hospital readmissions in esophageal atresia

PURPOSE

The purpose of this study is to identify determinants of mortality and hospital readmission in infants born with esophageal atresia ± tracheoesophageal fistula.

METHODS

The Nationwide Readmissions Database (2010-2014) was queried for newborns with a diagnosis of esophageal atresia. Outcomes included mortality and readmissions at 30-day and 1-year.

RESULTS

3157 patients were identified, of which 54% were male. 81% had an additional congenital anomaly, and 35% had VACTERL association. Overall mortality at index hospitalization was 11% (n = 360) and was significantly higher with additional congenital anomalies (13%), VACTERL (19%), and Spitz classification II/III (18%) vs. isolated esophageal atresia/tracheoesophageal fistula (4%), all p < 0.001. After esophageal atresia repair (n = 2179), 10% (n = 212) were readmitted within 30 days and 26% (n = 563) within 1 year, with 17% admitted to different hospitals. Common diagnoses during readmission were GERD (54%), infections (42%), failure to thrive (17%), tracheomalacia (14%), and esophageal stricture (10%). Unplanned readmissions accounted for 85% of readmissions. A large number underwent operative procedures, most commonly esophageal dilation (17%) and fundoplication/gastrostomy (12%).

CONCLUSION

Our study has uncovered a high likelihood of complications and unplanned readmission within the first year of life for newborns with esophageal atresia. Coordinated multidisciplinary care may help to decrease unnecessary readmissions and improve outcomes in this vulnerable population.

The effect of intralesional steroid injections on esophageal strictures and the child as whole: A case series

BACKGROUND

The most frequent complication after esophageal atresia repair remains anastomotic stricture formation. The initial treatment is endoscopic dilatation. Intralesional steroid injection (ISI) might be an effective adjuvant treatment in case of recurrent strictures. In this series we present our initial experience with this intervention.

METHODS

Data on primary surgery, stricture treatment, postoperative complications, outcome and growth were retrospectively collected from electronic patient records. Findings were analyzed by descriptive statistics and mixed model analysis.

RESULTS

Between 2014 and 2017, ISI was performed for severe recurrent anastomotic strictures in six patients (median age at injection 12.4 (2.1-34.7) months) after a median of 6 (2-20) dilatations. In five patients ISI was successful and the stenosis was cleared. No postoperative complications were reported, especially none related to acute adrenal suppression. Comparing the year before with the year after ISI, a significant positive change for weight (r = 0.70, p = 0.003) was calculated versus a negative change for height (r = -0.87, p = 0.003).

CONCLUSIONS

We found ISI to be an effective adjuvant treatment to recurrent anastomotic stricture dilatation after esophageal atresia repair, without postoperative complications or symptoms of adrenal suppression. It remains important, however, to monitor growth effects. Further evaluation is required in a large prospective study.

Fiberoptic bronchoesophagoscopy-assisted evaluation and prognostic factor analysis in children with congenital esophageal atresia and tracheoesophageal fistula

BACKGROUND

Esophageal atresia (EA) and tracheoesophageal fistula (TEF) are serious congenital anomalies with high morbidity and mortality. Diagnostic and therapeutic fiberoptic endoscopy has been used in children to evaluate and manage trachea-esophageal anomalies. This study aimed to evaluate the prognostic factors and the role of fiberoptic bronchoesophagoscopy (FB) in managing children with EA and TEF.

METHODS

From 2000 to 2017, hospitalized children with suspected EA and TEF were enrolled in the study. All associated medical records were retrospectively reviewed. Basic characteristics, diagnoses, age of surgical reconstruction, FB findings, associated anomalies, and survival durations were reviewed. Prognostic factors associated with the patients' mortality were analyzed.

RESULTS

A total of 33 children were enrolled, and 91% of them were type C. The median age at the time of hospitalization was 26 days (range, birth to 9 years), including 20 (61%) low-birth-weight infants and 26 (79 %) referred patients. FB was performed in patients preoperatively (39%) and postoperatively (96.8%). Among them, 28 patients (85%) had associated anomalies, including 17 (52%) cardiac and 23 (70%) airway anomalies. The median age of 31 patients who underwent surgical reconstruction was 3 (range, 0-39) days. Esophageal anastomotic stricture (21/31, 67.7%) was the most common postsurgical complication. Twenty-three patients (74.2%) received postoperative FB-guided interventions, including balloon dilatation, laser therapy, and stent implantation. Among the 9 mortality cases, the median age at death was 270 (range, 4-3246) days. Significant factor associated with mortality was delayed (> 48 h old) or no surgical reconstruction (p = 0.030).

CONCLUSION

Delayed (>48-hour old) or no surgical reconstruction was significantly related to mortality in children with congenital EA and TEF. Preoperative and postoperative FB evaluations helped to facilitate diagnoses and nonsurgical managements and resolve the patients' tracheoesophageal problems.

Intralesional steroid injections to prevent refractory strictures in patients with oesophageal atresia: study protocol for an international, multicentre randomised controlled trial (STEPS-EA trial)

INTRODUCTION

Anastomotic stricture formation is the most common postoperative complication after oesophageal atresia (OA) repair. The standard of care is endoscopic dilatation. A possible adjuvant treatment is intralesional steroid injection, which is thought to inhibit scar tissue formation and thereby to prevent stricture recurrence. We hypothesise that this intervention could prevent refractory strictures and reduce the total number of dilatations needed in these children.

METHODS AND ANALYSIS

This is an international multicentre randomised controlled trial. Children with OA type C (n=110) will be randomised into intralesional steroid injection followed by balloon dilatation or dilatation only. Randomisation and intervention will take place when a third dilatation is performed. The indication for dilatation will be confirmed with an oesophagram. One radiologist-blinded for randomisation-will review all oesophagrams. The primary outcome parameter is the total number of dilatations needed with <28 days' interval, which will be analysed with a linear-by-linear χ² association test. Secondary outcome parameters include the level of dysphagia, the luminal oesophageal diameter and stricture length (measured on the oesophagrams), the influence of comedication on stricture formation, systemic effects of intralesional steroids (cortisol levels, length and weight) and the cost-effectiveness. Patients will undergo a second oesophagram; length and weight will be measured repeatedly; a scalp hair sample will be collected; and three questionnaires will be administered. The follow-up period will be 6 months, with evaluation at 2-3 weeks, 3 and 6 months after the intervention.

ETHICS AND DISSEMINATION

Patients will be included after written parental informed consent. The risks and burden associated with this trial are minimal. The institutional review board of the Erasmus Medical Centre approved this protocol (MEC-2018-1586/NL65364.078.18). The results of the trial will be published in a peer-reviewed scientific journal and will be presented at international conferences.

Surgical management of critical congenital malformations in the delivery room

Newborn emergencies that occur in the delivery room are frequently the result of life-threatening congenital anomalies that can result in death or severe disability if not treated in the immediate postnatal period. Prompt recognition and treatment of such disorders are paramount to ensuring the wellbeing of the infant. As congenital anomalies are frequently being diagnosed earlier due to improved prenatal detection, the coordination of planned interventions for life-threatening malformations is also becoming more common. This article serves as a guide for the presentation and initial management of the most common non-cardiac, newborn surgical emergencies.

Laparoscopic Technique in the Management of High Anorectal Malformations: A Propensity Score-Matched Outcome Study Using a Large Inpatient Database

Background: Posterior sagittal anorectoplasty (PSARP) has been the standard for management of children with high anorectal malformations (ARMs). Recently, there has been an increase in the use of laparoscopy in its management. We analyzed the outcomes of laparoscopically assisted anorectal pull-through (LAARP) compared to PSARP using a large inpatient database. Methods: Kids' Inpatient Database was analyzed for ARM (ICD-9-CM 751.2) between 1997 and 2012. Perineal fistulas and low/intermediate ARM were excluded. Propensity score (PS)-matched analyses were performed using 37 variables. Cases were weighted to provide national estimates. Results: Of the overall 29,106 cases, 7428 patients <2 years underwent surgical repair. LAARP was performed in 178 patients. Eighty-eight percent were male. Most were of Caucasian (n = 71; 45%), followed by Hispanic (n = 41; 26%) descent. Most were performed in 2009 and 2012 (n = 149; 83%). Most were covered by Medicaid (88; 49%), followed by private insurance (80; 45%). Median length of stay (LOS) was 4 (interquartile range = 3) days. The majority were performed in a children's hospital (n = 90; 88%). On PS-matched analysis, LAARP had shorter median LOS (4 [3]) compared to PSARP (6 [15]) days, P = .003. Rates of reoperation, wound infection, wound dehiscence, and mortality were unchanged between approaches. Cost was lower for LAARP (47,969 [49,450]) versus PSARP (56,110 [160,314]) U.S. dollar , P = .002, whereas total charges did not differ significantly. Conclusions: A minimal access approach to a complex procedure requires significant time and resources to be adopted as standard. PSARP is an important example, as increased availability of laparoscopy, and therefore, access to the procedure for patients will greatly affect resource utilization and recovery for the patient. As demonstrated, the LOS and cost is significantly lower for the LAARP procedure in comparison to the traditional approach. Future research will clarify boundaries to introducing the laparoscopic approach as a potential standard technique in the next decade.

Neonatal surgery in low- vs. high-volume institutions: a KID inpatient database outcomes and cost study after repair of congenital diaphragmatic hernia, esophageal atresia, and gastroschisis

BACKGROUND/PURPOSE

The volume-outcome relationship and optimal surgical volumes for repair of congenital anomalies in neonates is unknown.

METHODS

A retrospective study of infants who underwent diaphragmatic hernia (CDH), gastroschisis (GS), and esophageal atresia/tracheoesophageal fistula (EA/TEF) repair at US hospitals using the Kids' Inpatient Database 2009-2012. Distribution of institutional volumes was calculated. Multi-level logistic/linear regressions were used to determine the association between volume and mortality, length of stay, and costs.

RESULTS

Total surgical volumes were 1186 for CDH, 1280 for EA/TEF, and 3372 for GS. Median case volume per institution was three for CDH and EA/TEF, and four for GS. Hospitals with annual case volumes ≥ 75th percentile were considered high volume. Approximately, half of all surgeries were performed at low-volume hospitals. No clinically meaningful association between volume and outcomes was found for any procedure. Median cost was greater at high- vs. low-volume hospitals [CDH: $165,964 (p < 0.0001) vs. $104,107, EA/TEF: $85,791 vs. $67,487 (p < 0.006), GS: $83,156 vs. $72,710 (p < 0.0009)].

CONCLUSIONS

An association between volume and outcome was not identified in this study using robust outcome measures. The cost of care was higher in high-volume institutions compared to low-volume institutions.

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.

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.

Risk factors for refractory anastomotic strictures after oesophageal atresia repair: a multicentre study

OBJECTIVE

To determine the incidence of refractory anastomotic strictures after oesophageal atresia (OA) repair and to identify risk factors associated with refractory strictures.

METHODS

Retrospective national multicentre study in patients with OA born between 1999 and 2013. Exclusion criteria were isolated fistula, inability to obtain oesophageal continuity, death prior to discharge and follow-up <6 months. A refractory oesophageal stricture was defined as an anastomotic stricture requiring ≥5 dilations at maximally 4-week intervals. Risk factors for development of refractory anastomotic strictures after OA repair were identified with multivariable logistic regression analysis.

RESULTS

We included 454 children (61% male, 7% isolated OA (Gross type A)). End-to-end anastomosis was performed in 436 (96%) children. Anastomotic leakage occurred in 13%. Fifty-eight per cent of children with an end-to-end anastomosis developed an anastomotic stricture, requiring a median of 3 (range 1-34) dilations. Refractory strictures were found in 32/436 (7%) children and required a median of 10 (range 5-34) dilations. Isolated OA (OR 5.7; p=0.012), anastomotic leakage (OR 5.0; p=0.001) and the need for oesophageal dilation ≤28 days after anastomosis (OR 15.9; p<0.001) were risk factors for development of a refractory stricture.

CONCLUSIONS

The incidence of refractory strictures of the end-to-end anastomosis in children treated for OA was 7%. Risk factors were isolated OA, anastomotic leakage and the need for oesophageal dilation less than 1 month after OA repair.

Relationships between hospital and surgeon operative volumes and outcomes of esophageal atresia/tracheoesophageal fistula repair

PURPOSE

Most pediatric surgeons perform <2 esophageal atresia and tracheoesophageal fistula (EA/TEF) repairs annually. We aimed to determine whether higher surgeon and hospital volumes are associated with better outcomes after EA/TEF repair.

METHODS

Neonates with a diagnosis and repair of EA/TEF at their index hospital admission in the Pediatric Health Information System from 1/2000 to 9/2015 were included. For each patient, hospital and surgeon operative volumes were defined as the number of EA/TEF cases treated in the previous 365 days. Propensity score weighting was used to estimate relationships between operative volumes and rates of in-hospital mortality, readmission within 30 days, and readmission, reoperation, and dilation within one year.

RESULTS

Among 3085 patients, lower birth weight, earlier gestational age, the presence of congenital heart disease, and certain other anomalies were associated with higher mortality. In risk-adjusted analyses, there were no significant differences in mortality or any other outcome based on hospital or surgeon volume alone or when comparing low- or high-volume surgeons practicing at low- or high-volume hospitals.

CONCLUSIONS

Neither surgeon nor hospital volume significantly impacted outcomes after EA/TEF repair. Our findings imply that selective referral and pediatric surgeon subspecialization in EA/TEF may not translate to improved outcomes.

What is the impact of the use of transanastomotic feeding tube on patients with esophageal atresia: a systematic review and meta-analysis

Background

The transanastomotic feeding tube (TAFT) is widely used around the world in patients with esophageal atresia (EA). However, the safety of the use of TAFT is still unknown and remains to be clarified.

Methods

The following electronic databases were searched: PubMed, EMBASE and Cochrane. Studies comparing outcomes in patients with the use of TAFT (TAFT+) and patients without the use of TAFT (TAFT-) were scrutinized. The quality of included studies was evaluated with the Newcastle–Ottawa scale score. Statistical heterogeneity was assessed using the I² value. A fixed or random-effect model was applied.

Results

Four retrospective controlled studies involving 455 patients were included. The pooled estimates showed that the use of TAFT significantly increased the risk of stricture, with a risk ratio (RR) of 1.83 (95% CI 1.30–2.58; P = 0.0005). The meta-analyses of other postoperative complications did not show significant differences between TAFT+ and TAFT- group, with a RR of 1.65 (95% CI 0.93–2.93; P = 0.09) for anastomotic leakage, 0.91 (95% CI 0.34–2.44; P = 0.85) for sepsis, 1.89 (95% CI 0.22–16.20; P = 0.56) for tracheomalacia, 0.50 (95% CI 0.13–1.93; P = 0.31) for gastroesophageal reflux, 1.29 (95% CI 0.28–5.92; P = 0.74) for wound infection, and 0.97 (95% CI 0.03–36.75; p = 0.99) for pneumonia.

Conclusions

This study demonstrates that the use of TAFT in patients with EA significantly increases the risk of stricture. However, TAFT is not associated with other complications, including anastomotic leakage, sepsis, tracheomalacia, gastroesophageal reflux, wound infection and pneumonia.
