Successful management of oesophageal atresia in Cameroon, Sub-Saharan Africa.

Background: Oesophageal atresia (EA) is the most common congenital anomaly of the oesophagus. Despite improvement of survival observed over the previous two decades in developed countries, the mortality remains very high and the management greatly challenging in resource-poor settings such as Cameroon. We report our experience of management of EA in this environment, with a successful outcome.

Materials And Methods: We prospectively assessed patients diagnosed with EA and operated in January 2019, at the University Hospital Centre of Yaounde. Records were reviewed for demographics, history and physical examinations, radiological findings, surgical procedures and outcomes. The study has received approval from the Institutional Ethics Committees.

Results: In total, six patients (three males and three females, sex ratio, 0.5; mean age at diagnosis, 3.6 days; range, 1-7 days) were assessed. A past history of polyhydramnios was found in one patient (16.7%). All patients were classified Waterston Group A at diagnosis, with Ladd-Swenson type III atresia. Early primary repair was performed in four patients (66.7%) and delayed primary repair in two patients (33.3%). Operative repair mainly involved resection of the fistula, suture of trachea and oesophagus end-to-end anastomosis, followed by interposition of vascularised pleural flap. Patients were followed up 24 months. With one late death, the survival rate was 83.3%.

Conclusion: Improvement has been achieved in the outcomes of neonatal surgery in Africa in the past two decades, but EA-related mortality remains relatively too high. Using simple techniques and available, reproducible equipment can improve survival in resource-poor settings.
