Tracheoesophageal anomalies in Waterston C neonates: a 30-year perspective
Insights
Improved neonatal intensive care has significantly increased survival rates for infants with congenital tracheoesophageal anomalies. Advances in treatment led to better outcomes, especially for high-risk newborns requiring mechanical ventilation.
Area of Science:
- Pediatric Surgery
- Neonatology
- Congenital Anomalies
Background:
- Congenital tracheoesophageal anomalies affect numerous infants, posing significant surgical and survival challenges.
- Historically, high-risk infants (defined by Waterston's criteria) had poor prognoses.
- Management strategies have evolved, particularly with the advent of mechanical ventilation and neonatal intensive care.
Purpose of the Study:
- To evaluate the impact of evolving neonatal care on the outcomes of infants with tracheoesophageal anomalies.
- To compare survival rates and complications between two distinct treatment eras.
Main Methods:
- Retrospective analysis of 278 infants managed between 1955 and 1984.
- Classification of infants into high-risk and low-risk groups based on Waterston's criteria.
- Division into two groups (1955-1969 and 1970-1984) corresponding to changes in neonatal care.
Main Results:
- Infants in the later group (II) had lower birth weights and higher rates of prematurity (<32 weeks gestation).
- Operative survival improved dramatically from 30% in group I to 74% in group II (P < .05).
- Long-term survival also showed a significant increase from 15% to 64% (P < .05).
Conclusions:
- Advances in neonatal intensive care and mechanical ventilation have markedly improved survival for infants with tracheoesophageal anomalies.
- Despite improved survival, long-term complications like recurrent pneumonias and esophageal dysmotility remain significant concerns.
- Early intervention and specialized care are crucial for optimizing outcomes in this vulnerable population.
Abstract:
Two hundred and seventy-eight infants with congenital tracheoesophageal anomalies have been managed at the Columbus Children's Hospital since 1955. Fifty-four (20%) have been classified as high risk using Waterston's criteria of birth weight, associated anomalies, and pneumonitis. The infants have been divided into group I (n = 27, 1955 to 1969) and group II (n = 27, 1970 to 1984) to reflect the onset of mechanical ventilation and effective neonatal intensive care. The mean birth weight of infants in group II was significantly less than in group I (1,753 +/- 390 g v 1,950 +/- 505 g, P less than .05). The incidence of prematurity, measured by gestational age, has significantly increased with 9 of 27 (33%) infants in group II and 2 of 27 (7%) infants in group I less than 32 weeks gestation (P less than .05). The presence or severity of associated anomalies was not significantly different in groups I and II. Twenty patients in group I and 22 patients in group II underwent definitive management of their tracheoesophageal anomaly. Operative survival was 30% in group I and 74% in group II (P less than .05). Long-term survival was 15% in group I and 64% in group II (P less than .05). Early postoperative complications included aspiration pneumonitis, anastomotic leak, or stricture. The most frequent complications in long-term follow-up were recurrent pneumonias, which were observed in 9 of 16 children. Esophageal dysmotility or gastroesophageal reflux was documented in five of these children; four were managed successfully with positional or pharmacologic manipulations while one required an antireflux procedure. Thirty percent (5/16) are asymptomatic.(ABSTRACT TRUNCATED AT 250 WORDS)
