AI Article Synopsis
- The study analyzed 159 patients with esophageal atresia treated at Osaka University Medical School from 1957-1995, revealing improved survival rates over time, from 28% to 80%.
- It was found that 65.2% of patients in the latter periods had associated anomalies, with cardiovascular and gastrointestinal issues being the most common.
- Despite improved survival rates, significant postoperative complications persisted, including high rates of anastomotic leakage and gastroesophageal reflux, indicative of ongoing challenges in patient management.
Article Abstract
Background: One hundred fifty-nine patients who had esophageal atresia with or without tracheoesophageal fistula have been treated at Osaka University Medical School and its affiliated hospitals since the initial (Japanese) experience of Dr T. Ueda in 1957.
Methods: These cases were divided chronologically into three groups. With earlier recognition of surgical neonates and the development of perinatal care, the long-term survival of these patients has steadily improved over 39 years from 28% in the first period (1957 to 1967) to 80% in the third period (1980 to 1995). Of 141 patients treated in the second and third periods (1968 to 1995), 92 (65.2%) had associated anomalies. Cardiovascular and gastrointestinal malformations were the most frequently seen major anomalies. VATER or VACTER association was seen in 12.8% (18 of 141) of these patients. Survival of these cases according to Waterston risk factors was 100% for group A, 100% for group B, and 50% for group C, whereas the new classification proposed by Spitz showed survival of 92% for group 1, 50% for group 2, and 0% for group 3, showing better differentiation among the three groups.
Results: There was a long gap between the proximal and distal esophageal ends in seven patients (type A), in all of whom primary anastomosis was possible after 28 to 128 days of elongation by bouginage. Although the survival of esophageal atresia patients dramatically improved in recent years, there is still a high incidence of early and long-term postoperative complications, ie, anastomotic leakage (26.5%), recurrent fistula (7.2%), anastomotic stricture (49.1%), postoperative pneumonia or atelectasis (57.0%), tracheomalacia (25.8%), and gastroesophageal reflux (52.0%).
Conclusions: Recently, there have been changing patterns in the occurrence of complications, which are mainly attributed to technical improvement, better perinatal care and early recognition of pathophysiologic conditions such as tracheomalacia and gastroesophageal reflux.

Supporting the continuous development and use of a patient partnership framework in European rare disease networks (ERNs): a scoping review of frameworks in the scientific literature.
J Community Genet

EURORDIS - Rare Diseases Europe, Paris, France.
The European Reference Networks (ERNs) for rare and complex diseases offer significant potential for building, maintaining and evaluating patient partnership, for which the recently developed ERN Patient Partnership Framework may serve as guidance. This scoping review aims to identify and describe relevant frameworks published in scientific literature, capturing key learning points to inform future updates of the ERN Patient Partnership Framework and promote its use in practice. MEDLINE, Embase, and the Web of Science Core Collection were searched to identify recently published frameworks (2013-2023) focused on patient partnership and aligned with at least one core ERN activity.

Background: Elective ventilation and paralysis have been shown to decrease the anastomosis-related complications following primary repair of esophageal atresia (EA). Repeated endotracheal tube (ETT) block and replacement can increase these complications. We evaluated the results of our strategy of electively changing the ETT just before shifting the patient to the postoperative ward for elective ventilation.

Background: In March 2024, children with pulmonary hypoplasia, airway stenosis, congenital esophageal atresia, inborn errors of metabolism, and neuromuscular diseases became eligible for palivizumab in Japan. Despite limited epidemiological data, expert consensus guided the recommendation for palivizumab use in these children to ensure its proper application.
Objectives: This article outlines the proper use of palivizumab for RSV infection in infants and children with the specified conditions, aiming to enhance understanding of the medical basis for its clinical guidance.
Specific Findings of Blood Perfusion on Anastomosed Esophagus of Neonatal Esophageal Atresia and Tracheoesophageal Fistula Using Indocyanine Green Fluorescence During Thoracoscopic Surgery.

We herein report a neonatal case showing specific findings of blood perfusion in the anastomosed esophagus of esophageal atresia (EA) and tracheoesophageal fistula (TEF) using indocyanine green (ICG) fluorescence during thoracoscopic surgery. The patient was a 3054 g, 0-day neonatal boy diagnosed with EA-TEF based on a coil-up sign of the nasogastric tube. Thoracoscopic surgery was performed on Day 4 after birth.

Introduction: Tracheomalacia (TM) often occurs in children with oesophageal atresia (OA), leading to recurrent respiratory symptoms and in severe cases to blue spells or ultimately respiratory arrest. In some patients, a secondary posterior tracheopexy may then be indicated. This secondary surgery, as well as respiratory morbidity, may be prevented by performing a primary posterior tracheopexy (PPT) concurrent with primary OA correction.
