Swallowing and feeding disorders are a major concern for children with oesophageal atresia (OA) after primary or staged OA repair. Primary OA repair is associated with higher rates of short-term complications in preterm infants with very low birth weight (VLBW) or extreme low birth weight (ELBW). On the other hand, primary repair may have the benefit of early commencement of oral feedings. We hypothesize that also in the medium-term, swallowing-related quality of life is better after primary oesophageal repair. We conducted a prospective cross-sectional study on swallowing quality in a national cohort of former VLBW and ELBW children with OA, using the structured paediatric swallowing quality of life (pedSWAL-QOL) questionnaire. Results were correlated with surgical approach and baseline clinical data. Principal component analysis of pedSWAL-QOL domains was performed. In total, 44 complete data sets of 78 children were available. The mean age of children was 8.5 years (SD = 7.4), and 23 children (52%) had primary OA repair. The overall median pedSWAL-QOL score was 2 (IQR = 0–3), representing a high swallowing-related quality of life, independent of surgical technique (p = 0.086). Children with a history of intracranial haemorrhage (ICH) (p = 0.002) and those with VACTERL association (p = 0.008) had significantly decreased enjoyment with eating. In addition, children with VACTERL association had problems to find suitable foods (p = 0.04). Conclusion: In this national cohort of VLBW and ELBW preterm-born children with OA, swallowing-related quality of life is good, mostly independent of initial surgery. Children with OA and ICH or VACTERL association may require more intense support with feeding. What is Known:• Dysphagia, resembling feeding and swallowing disorders, is common in children and adults with repaired oesophageal atresia. Nevertheless, dysphagia in children with oesophageal atresia decreases with age.• Parents of younger children suffer from increased anxiety and fear regarding eating and swallowing abilities of their children. What is New:• Swallowing-related quality of life in former preterm children with oesophageal atresia is good, independent of initial surgical approach (primary vs. staged repair), even in very low birth weight or extreme low birth weight infants. • Children suffering from VACTERL association or intracranial haemorrhage show decreased enjoyment with eating.

ZusammenfassungDie Ösophagusatresie (ÖA) ist eine angeborene Kontinuitätsunterbrechung der Speiseröhre mit oder ohne Fistel zur Trachea (Tracheoösophageale Fistel, TÖF). Je nach Abstand zwischen den beiden Ösophagusenden unterscheidet man eine „kurzstreckige“ von einer „langstreckigen“ Form. Bis zu 50% der Neugeborenen weisen weitere Anomalien auf. Eine pränatale Diagnose der ÖA gelingt in 32–63% der Fälle. Die interdisziplinäre Betreuung dieser Kinder hat sich in den letzten Jahren gewandelt. In der folgenden Arbeit wird die aktuelle S2K-Leitlinie der Deutschen Gesellschaft für Kinderchirurgie zur Behandlung der ÖA mit unterer TÖF, die etwa 90% aller Fälle ausmacht, zusammengefasst. Hierzu gehören das präoperative Management sowie operative und anästhesiologische Aspekte (u. a. Thorakoskopie vs. Thorakotomie, präoperative Tracheobronchoskopie, intraoperative Hyperkapnie und Azidose). Ferner wird das postoperative Management insbesondere von relevanten Komplikationen wie der Anastomosenstenose beschrieben. Trotz Fortschritten in der Behandlung der ÖA ist die Langzeitmorbidität mit Motilitätsstörungen des Ösophagus, gastroösophagealer Refluxkrankheit, rezidivierenden Infektionen der oberen und unteren Atemwege, Tracheomalazie, mangelhaftem Gedeihen sowie orthopädischen Problemen nach Thorakotomie weiterhin hoch. Zum Erreichen einer guten Lebensqualität ist daher eine gute interdisziplinäre Nachsorge wichtig.

Introduction: Primary repair of esophageal atresia (EA) in infants with very low birth weight (VLBW) and extremely low birth weight (ELBW) has been widely performed in pediatric surgery. However, several studies have shown that complication rates in infants with VLBW are high. We hypothesize preterm children benefit from a shorter, less-traumatizing operation in the first days of life, as staged repair implies. Methods: Patients with EA and VLBW were retrieved from the database of a large national patient organization KEKS e.V. Structured questionnaires were sent to all the patients' families; the responses were pseudonymized and sent to our institution. Results: Forty-eight questionnaires from patients were analyzed. The mean birth weight was 1,223 g (720–1,500 g). Primary repair was performed in 25 patients (52%). Anastomotic insufficiency (AI) was reported in 9 patients (19%), recurrent fistula (RF) in 8 (17%), and anastomotic stenosis in 24 patients (50%). Although AI was almost twice as common after primary repair than after staged repair (24 vs. 13%; p = 0.5), the difference was not statistically significant. RF was more frequent after primary repair (28 vs. 4%; p = 0.04), gastroesophageal reflux was more frequent in the group after staged repair (78 vs. 52%; p = 0.04), and both correlations were statistically significant. Intracranial hemorrhage (ICH) was reported in 11 patients (23%) and was observed in 7 of them (64%, p = 0.4) after primary repair. ICH was reported in 60% of patients with ELBW and 75% of patients when ELBW was paired with primary repair. Conclusion: This study demonstrates the complication rate in patients with VLBW is higher than the average of that in patients with EA. The study indicates that a staged approach may be an option in this specific patient group, as less RF and AI are seen after staged repair. ICH rate in patients with ELBW seemed to be especially lower after staged repair. Interestingly, gastroesophageal reflux was statistically significantly higher in the group after staged repair, and postoperative ventilation time was longer. It is therefore necessary to individually consider which surgical approach is appropriate for this special patient group.

Introduction Many aspects of the management of esophageal atresia (EA) and tracheoesophageal fistula (TEF) are controversial and the evidence for decision making is limited. Members of the European Reference Network for Rare Inherited Congenital Anomalies (ERNICA) conducted a consensus conference on the surgical management of EA/TEF based on expert opinions referring to the latest literature. Materials and Methods Nineteen ERNICA representatives from nine European countries participated in the conference. The conference was prepared by item generation, item prioritization by online survey, formulation of a final list containing the domains diagnostics, preoperative, operative, and postoperative management, and literature review. The 2-day conference was held in Berlin in October 2018. Anonymous voting was conducted via an internet-based system. Consensus was defined when 75% of the votes scored 6 to 9. Results Fifty-two items were generated with 116 relevant articles of which five studies (4.3%) were assigned as level-1evidence. Complete consensus (100%) was achieved on 20 items (38%), such as TEF closure by transfixing suture, esophageal anastomosis by interrupted sutures, and initiation of feeding 24 hours postoperatively. Consensus ≥75% was achieved on 37 items (71%), such as routine insertion of transanastomotic tube or maximum duration of thoracoscopy of 3 hours. Thirteen items (25%) were controversial (range of scores, 1–9). Eight of these (62%) did not reach consensus. Conclusion Participants of the conference reached significant consensus on the management of patients with EA/TEF. The consensus may facilitate standardization and development of generally accepted guidelines. The conference methodology may serve as a blueprint for further conferences on the management of congenital malformations in pediatric surgery.

Introduction Evidence supporting best practice for long-gap esophageal atresia is limited. The European Reference Network for Rare Inherited Congenital Anomalies (ERNICA) organized a consensus conference on the management of patients with long-gap esophageal atresia based on expert opinion referring to the latest literature aiming to provide clear and uniform statements in this respect. Materials and Methods Twenty-four ERNICA representatives from nine European countries participated. The conference was prepared by item generation, item prioritization by online survey, formulation of a final list containing items on perioperative, surgical, and long-term management, and literature review. The 2-day conference was held in Berlin in November 2019. Anonymous voting was conducted via an internet-based system using a 1 to 9 scale. Consensus was defined as ≥75% of those voting scoring 6 to 9. Results Ninety-seven items were generated. Complete consensus (100%) was achieved on 56 items (58%), e.g., avoidance of a cervical esophagostomy, promotion of sham feeding, details of delayed anastomosis, thoracoscopic pouch mobilization and placement of traction sutures as novel technique, replacement techniques, and follow-up. Consensus ≥75% was achieved on 90 items (93%), e.g., definition of long gap, routine pyloroplasty in gastric transposition, and avoidance of preoperative bougienage to enable delayed anastomosis. Nineteen items (20%), e.g., methods of gap measurement were discussed controversially (range 1–9). Conclusion This is the first consensus conference on the perioperative, surgical, and long-term management of patients with long-gap esophageal atresia. Substantial statements regarding esophageal reconstruction or replacement and follow-up were formulated which may contribute to improve patient care.

Esophageal atresia (EA) is a congenital anomaly that entails an interrupted esophagus with or without tracheoesophageal fistula (TEF). Depending on the distance of the two esophageal pouches a "short-gap" is distinguished from a "long-gap" variant. Up to 50% of newborns have additional anomalies. EA is prenatally diagnosed in 32-63% of cases. Recently, the interdisciplinary care in these children underwent substantial changes. Therefore, we summarize the current guideline of the German society of pediatric surgery for the treatment of patients with EA and distal TEF (Gross Type C). Controversies regarding the perioperative management include surgical-technical aspects, such as the thoracoscopic approach to EA, as well as general anesthesia (preoperative tracheobronchoscopy, intraoperative hypercapnia and acidosis). Moreover, postoperative complications and their management like anastomotic stricture are outlined. Despite significant improvements in the treatment of EA, there is still a relevant amount of long-term morbidity after surgical correction. This includes dysmotility of the esophagus, gastroesophageal reflux disease, recurrent respiratory infections, tracheomalacia, failure to thrive, and orthopedic complications following thoracotomy in the neonatal age. Therefore, close follow-up is mandatory to attain optimal quality of life.Die Ösophagusatresie (ÖA) ist eine angeborene Kontinuitätsunterbrechung der Speiseröhre mit oder ohne Fistel zur Trachea (Tracheoösophageale Fistel, TÖF).

Long term outcomes of esophageal atresia (OA) are poorly understood. The Federation of Esophageal Atresia and Tracheo-Esophageal Fistula support groups (EAT), a collaboration of patient support groups aimed to define patient reported long term outcomes and quality of life (QoL) in a large international cohort of OA patients.Questionnaires were designed focusing on patient/parent reported outcomes including surgical history, current symptomatology and quality of life. Members of support groups within EAT were invited to complete questionnaires electronically via SurveyMonkey®.1100 patients from 25 countries responded to the questionnaire and 928 were analyzed. 80% had type C anatomy, 19% type A and 1% type E. Patient ages were5 years (42%), 5-10 years (26%), 11-17 years (16%) and 18 years and older (16%). 49% of all patients reported previous dilatations which was similar across age groups. Reflux symptoms affected 58% of patients and persisted into adulthood. Dysphagia also persisted in the adult population with 50% reporting sometimes or often getting food stuck. Reflux was significantly more frequent in 'long gap' versus 'standard gap' patients (p0.005). Respiratory symptoms and chest infections decreased in frequency with age. In children median SDS for height was -0.41 (IQR -1.4 to 0.67) and that for weight was -0.63 (-1.6 to 0.67). BMI in adults was 21.5. Quality of life was described as significantly affected by OA in 18% of patients while 25% reported no effect on QoL.These results highlight the significant long term morbidity suffered by OA patients as children and into adulthood and suggest the need for quality transitional care. The patient designed and reported nature of the study gives a unique perspective to the results and emphasizes the benefits of collaboration.

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.
