Abstract:
Introduction: Esophageal atresia (EA) is a congenital anomaly that causes a blind-ending esophagus with or
without tracheoesophageal fstula (TEF). The global incidence ranges from 1:3500 to 1:4500 live births. In highincome countries, mortality rates have declined owing to advances in surgical expertise, neonatal care, and early
diagnosis, although morbidity has increased. This improvement remains limited in low- and middle-income
countries, where aspiration pneumonia and sepsis cause high mortality owing to delayed diagnosis, preoperative feeding, and poor referral systems. This study describes the management and outcomes of EA at Moi
Teaching and Referral Hospital (MTRH) in Kenya.
Method: A 13-year retrospective cohort study was conducted by reviewing the medical records of patients
managed for EA/TEF at MTRH from January 2010 to December 2022. These included demographic characteristics, pre- and postnatal details, clinical interventions, intraoperative fndings, and postoperative outcomes.
Results: Among 67 patients with esophageal atresia, 64.2 % were male and 86.6 % were full-term. Cardiac
anomalies occurred in 53.8 % of patients, most commonly patent ductus arteriosus, while non-cardiac anomalies
were present in 19.4 %. The overall mortality was 44.8 %. Age at admission, birth weight, and surgical leaks did
not signifcantly affect the outcomes. Sepsis was strongly associated with mortality (33.3 % in deaths vs. 5.4 % in
survivors; p < 0.001). Patients who did not receive postoperative mechanical ventilation had higher adjusted
odds of death (AOR 5.5, 95 % CI: 1.02–29.55, p = 0.048).
Conclusion: Pneumonia and sepsis remain the major contributors to mortality in this population. Improved
referral pathways to reduce diagnostic delays and tailored postoperative ventilation strategies may enhance
survival outcomes in patients with EA/TEF.
