Predictors of index admission mortality and morbidity in contemporary esophageal atresia patients

BACKGROUND/PURPOSE

The Spitz classification for esophageal atresia with/without tracheoesophageal fistula (EA/TEF) predicts mortality. This study evaluates the contemporary relevance of the Spitz classification and investigates predictors of morbidity.

METHODS

EA/TEF patients born between 1995 and 2018 at two centers were retrospectively reviewed. Clinical variables including sex, prenatal diagnosis, birth weight, prematurity, major congenital heart disease (MCHD), and pre-operative mechanical ventilation (POMV) were collected. Index admission composite morbidity was considered positive if: length-of-stay >90th percentile (139 days), ventilation days >90th percentile (24 days), and/or gastrostomy was used for long-term feeding. Multivariable regression determined predictors of index admission mortality and composite morbidity. A composite morbidity predictive algorithm was created. ROC curves evaluated model discrimination.

RESULTS

Of 253 patients, 13 (5.1%) experienced index admission mortality. Of the patients not suffering mortality, 74 (31.6%) experienced composite morbidity. Only MCHD predicted mortality (p = 0.001); birth weight did not (p = 0.173). There was no difference between the Spitz classification and MCHD alone in predicting mortality risk (p = 0.198); both demonstrated very good discrimination. Prenatal diagnosis, POMV, prematurity, and male sex predicted composite morbidity risk (p < 0.001; p = 0.008; p = 0.009; p = 0.05). An algorithm incorporating these predictors demonstrated good discrimination (AUC = 0.784; 95% CI: 0.724, 0.844).

CONCLUSIONS

The Spitz classification maintains contemporary relevance for mortality risk, though birth weight can be de-emphasized. A new morbidity risk algorithm is proposed for early postnatal counseling.

Error traps and culture of safety in esophageal atresia repair

Esophageal atresia (EA) repair has always been a source of immense professional gratification for the pediatric surgeon. In many ways, this anomaly defines the entire profession. Due to its rarity, there is an increased risk of inadvertent events occurring during correction. This article describes some of the error traps that may occur in attempting esophageal reconstruction and how they may be avoided.

Prenatal diagnosis of esophageal atresia: A case of triple negative screening

Esophageal atresia (EA) is prenatally diagnosed in less than one third of the cases and is usually only suspected. Recently, magnetic resonance imaging (MRI) with dynamic sequence and biochemistry of the amniotic fluid have been proposed to enhance prenatal diagnosis of EA. We report the case of a triple negative screening (ultrasound, MRI with dynamic sequence and biochemistry of the amniotic fluid) with a postnatal diagnosis of EA type III with a small defect. Even using second line tests, prenatal diagnosis of EA remains a challenge.

Esophageal Atresia and Upper Airway Pathology

Esophageal atresia is an anomaly with frequently occurring sequelae requiring lifelong management and follow-up. Because of the complex issues that can be encountered, patients with esophageal atresia preferably should be managed in centers of expertise that have the ability to deal with all types of anomalies and sequelae and can perform rigorous lifelong follow-up. Tracheomalacia is an often-occurring concurrent anomaly that may cause acute life-threatening events and may warrant immediate management. In the past, major thoracotomies were necessary to carry out the aortopexy. Nowadays, aortopexy and posterior tracheopexy can both be performed thoracoscopically with quick recovery.
