The effect of postoperative ventilation strategies on postoperative complications and outcomes in patients with esophageal atresia: Results from the Turkish Esophageal Atresia Registry

Prevalence, Mortality, and Associated Anomalies in Esophageal Atresia: A Retrospective Study of Finnish Population Data (2004-2017)

INTRODUCTION

 The aim of the study was to investigate the prevalence of esophageal atresia (EA), frequency of associated anomalies, and mortality from 2004 to 2017 in the Finnish population. We hypothesized the Spitz classification and the presence of other congenital malformations would predict mortality in patients with EA as well as assumed the survival to be high among patients with EA.

MATERIALS AND METHODS

 This retrospective, population-based study was based on the registries maintained by THL Finnish Institute for Health and Welfare and Statistics Finland. The cases were identified and classified according to the World Health Organization's International Classification of Diseases and Health Related Problems (ICD) revisions 9 and 10 (ICD-9 and ICD-10) codes and accompanying written diagnoses. Associated anomalies were classified based on the EUROCAT criteria, and minor anomalies were excluded. All statistical tests were performed as a two-sided significance level set at p < 0.05. The chi-square or Fisher's exact test was utilized for categorical variables. The change in prevalence rates during the study period was evaluated with linear regression.

RESULTS

 In total, 337 cases with EA were identified including 295 (87.5%) live births, 17 (5.0%) stillbirths, and 25 (7.4%) terminations of pregnancy. The total prevalence for EA in Finland was 4.17/10,000 births with no significant change during the study period, p = 0.35. Neonatal mortality was 5% (n = 15) and 1-year survival was 91.5%. Mortality was associated with syndromic cases (p = 0.002). The Spitz classification predicted neonatal mortality better than cardiac anomalies alone (p < 0.001 and p = 0.6, respectively). Type C was the most common atresia type (65.9%) followed by type A (14.8%) and B (6.8%). The most common group of associated malformations were heart defects (35.0%) followed by other gastrointestinal tract malformations (15.3%) and limb anomalies (12.2%). Syndromic cases (12.2%) were associated with type A and B atresias (p = 0.001). VACTERL association was observed in 16.6% of the cases.

CONCLUSION

 The overall prevalence of EA remains stable and relatively high in Finland. Despite the high prevalence of co-occurring malformations, the overall survival rate is high. Spitz classification predicted neonatal survival well.

IMPACT OF MUSCLE PARALYSIS AFTER PRIMARY ESOPHAGEAL ATRESIA REPAIR

BACKGROUND

Post-operative muscle paralysis aims to reduce anastomotic complications following primary esophageal atresia (EA) repair. This study evaluates the impact of paralysis on outcomes in children enrolled in the EUPSA Esophageal Atresia Registry (EAR).

METHODS

Patients with type B, C, and D EA enrolled in the EAR between 2014 and 2017 who underwent primary EA repair were included. They were divided into two groups based on the use of paralysis (Group P) or not (Group NP). Comparisons included demographics, associated malformations, surgical approach, complications, and hospital stay. Multivariate logistic regressions analyses were performed.

RESULTS

Of 316 patients, 126 were in Group P and 190 in Group NP. Group P had significantly lower gestational age and birth weight. Ventilation duration (7.9 ± 10.4 vs. 4.0 ± 4.4 days; p < 0.001) and hospital stay (43.7 ± 93.7 vs. 27.5 ± 31.8 days; p < 0.001) were significantly longer in Group P. The overall complication rate was higher in Group P (39.7% vs. 28.4%; p = 0.036), but mortality rates did not differ significantly. Post-operative paralysis was not associated with a significant reduction in anastomotic leaks or strictures.

CONCLUSIONS

Post-operative paralysis may provide stability in high-risk cases, such as neonates with low birth weight or associated malformations, but it does not significantly reduce surgical complications and may prolong recovery. Its use should be carefully considered and limited to individualized scenarios where the benefits outweigh the risks.

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

INTRODUCTION

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Benchmarks for Pediatric Surgical Registries: Recommendations for the Assessment and Grading of Complications

Procedure-related registries in general surgical practice offer a platform for prospective trials, the pooling of data, and detailed outcome analysis. Recommendations by the Idea, Development, Exploration, Assessment, and Long-term follow-up (IDEAL) collaboration and Outcome4Medicine have further improved the uniform reporting of complications and adverse events.In the pediatric surgical network, disease-specific registries for rare and inherited congenital anomalies are gaining importance, fostering international collaborations on studies of low-incidence diseases. However, to date, reporting of complications in the pediatric surgical registries has been inconsistent. Therefore, the European Reference Network for Rare Inherited and Congenital Anomalies (ERNICA) recently endorsed the validation of the first severity grading system for children. The planned reform of the European Paediatric Surgical Audit (EPSA) registry, which includes the implementation of the Clavien-Madadi classification, represents a further effort to establish uniform outcome reporting.This article provides an overview of experiences with surgical registries and complication reporting, along with the potential application of this knowledge to future pediatric surgical practice.

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

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