Transitioning from thoracotomy to thoracoscopy for esophageal atresia in an LMIC setting

Introduction: Although the benefits of thoracoscopic esophageal atresia repair (TEAR) are well documented, there has been resistance to the uptake of this approach in low- and middle-income countries. This study reviews a single unit's experience introducing TEAR in a South African state sector tertiary hospital. Method: We describe how we set up MIS for esophageal atresia (EA) at our centre. All neonates with EA managed at our institution from January 2016 to January 2022 were included. Excluded patients included those who were not operated on or if data was missing. We compared the different approaches for managing type C EA in our setting. We analyzed the data using the Mann-Whitney U test. Results: Sixty-five patients were managed with EA over the study duration. There were 54 patients who had type C EA. Thirty-nine patients underwent thoracotomy to repair the defect, and eighteen underwent TEAR, of which sixteen were completed thoracoscopically. There was a statistically significant difference in weight (p-value 0.035), gestational age (p-value 0.002), and age at operation (p-value 0.004) between the groups treated by TEAR and OEAR (open esophageal atresia repair). There was a small median difference in the operative time between TEAR and OEAR of 20 min. The mortality in the OEAR group was higher (20.5 %) compared to the TEAR group (5.5 %), with a p-value of 0.094. Conclusion: A dedicated quality improvement program focused on introducing MIS for EA can produce results comparable to the open procedure in an LMIC setting
