Thoracotomy vs. Thoracoscopy for Esophageal Atresia with Tracheoesophageal Fistula Repair: Is There a Difference in Quality of Life?

AIM

Esophageal atresia (EA) is the most common congenital esophageal malformation. Thoracoscopic repair is gaining popularity, but controversy persists regarding the ideal surgical approach for this challenging anomaly. This study's aim is to analyze outcomes in terms of quality of life (QoL) of children undergoing thoracotomy and thoracoscopy for type III EA repair.

METHODS

Perinatal characteristics, malformations, surgical procedures, complications, gastrointestinal, and respiratory current symptoms were collected. QoL was investigated through Esophageal-Atresia-QoL (EAQoL) and Pediatric-QoL (PedsQL) 4.0 standardized and validated questionnaires. Statistical Mann-Whitney test with significance level p < 0.05 was carried out.

MAIN RESULTS

A total of 32 patients undergoing type III EA primary repair answered the questionnaire, including 17 thoracotomy and 15 thoracoscopy. Median birth weight was not significantly different between two groups (median [2.385; 2.475], p = 0.3529) while gestational age showed statistically difference (median [36; 38], p = 0.0063). Thirty-five associated malformations (15 thoracotomy, 20 thoracoscopy) in 23 patients were observed. Postoperative complications occurred in nine patients in the thoracotomy group (one recurrent fistula, two leakages, six stenosis) and in six patients in the thoracoscopic group (two recurrent fistula, four stenosis). Analyzing EAQoL, we found statistically significant difference in physical health between the two groups (median [83; 96], p = 0.0119), while there was no difference in social relations, eating, and total score (median [100; 100], p = 0.3473) (median [91; 97], p = 0.5749) (median [91; 96], p = 0.1710). Investigating PedsQL, psychosocial health score (median [88; 98], p = 0.0069), and total score (median [91;99], p = 0.0043) were statically significant different between the groups, whereas there was no difference for physical health score (median [91; 100], p = 0.0706).

CONCLUSIONS

Thoracoscopic EA repair is safe and feasible, allowing patient to have a better QoL in terms of physical and psychosocial health score.

Histological, immunohistochemical and transcriptomic characterization of human tracheoesophageal fistulas

Esophageal atresia (EA) and tracheoesophageal fistula (TEF) are relatively frequently occurring foregut malformations. EA/TEF is thought to have a strong genetic component. Not much is known regarding the biological processes disturbed or which cell type is affected in patients. This hampers the detection of the responsible culprits (genetic or environmental) for the origin of these congenital anatomical malformations. Therefore, we examined gene expression patterns in the TEF and compared them to the patterns in esophageal, tracheal and lung control samples. We studied tissue organization and key proteins using immunohistochemistry. There were clear differences between TEF and control samples. Based on the number of differentially expressed genes as well as histological characteristics, TEFs were most similar to normal esophagus. The BMP-signaling pathway, actin cytoskeleton and extracellular matrix pathways are downregulated in TEF. Genes involved in smooth muscle contraction are overexpressed in TEF compared to esophagus as well as trachea. These enriched pathways indicate myofibroblast activated fibrosis. TEF represents a specific tissue type with large contributions of intestinal smooth muscle cells and neurons. All major cell types present in esophagus are present-albeit often structurally disorganized-in TEF, indicating that its etiology should not be sought in cell fate specification.

The Impact of Congenital Esophageal Atresia on the Family Functioning

PURPOSE

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

DESIGN AND METHODS

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

RESULTS

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

CONCLUSION

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