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

ObjectivesPostoperative ventilatory strategies in patients with esophageal atresia (EA) and tracheoesophageal fistula (TEF) may have an impact on early postoperative complications. Our national Esophageal Atresia Registry was evaluated to define a possible relationship between the type and duration of respiratory support on postoperative complications and outcome. Study DesignAmong the data registered by 31 centers between 2015 and 2021, patients with esophago-esophageal anastomosis (EEA)/tracheoesophageal fistula (TEF) were divided into two groups; invasive ventilatory support (IV) and noninvasive ventilatory support and/or oxygen support (NIV-OS). The demographic findings, gestational age, type of atresia, associated anomalies, and genetic malformations were evaluated. We compared the type of repair, gap length, chest tube insertion, follow-up times, tensioned anastomosis, postoperative complications, esophageal dilatations, respiratory problems requiring treatment after the operation, and mortality rates. ResultsAmong 650 registered patients, 502 patients with EEA/TEF repair included the study. Four hundred and seventy of patients require IV and 32 of them had NIV-OS treatment. The IV group had lower mean birth weights and higher incidence of respiratory problems when compared to NIV-OS group. Also, NIV-OS group had significantly higher incidence of associated anomalies than IV groups. The rates of postoperative complications and mortality were not different between the IV and NIV-OS groups. ConclusionWe demonstrated that patients who required invasive ventilation had a higher incidence of low birth weight and respiratory morbidity. We found no relation between mode of postoperative ventilation and surgical complications. Randomized controlled trials and clinical guidelines are needed to define the best type of ventilation strategy in children with EA/TEF

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
