RESUMO
BACKGROUND: We describe a technical modification to approach for dissection of proximal pouch in patients undergoing the primary repair of congenital Esophageal atresia with tracheoesophageal fistula (EA-TEF). METHODS: A prospective comparative study was performed from January 2016 to December, 2019 including the patients who were undergoing primary repair of EA-TEF (Type C). The patients were divided into Group A (upper pouch dissection by classical approach) and Group B (technical modification). The two groups were compared for operative outcome and complications. Modified OSATS score was used to rate the performance of operators in two groups and were compared. RESULTS: Total of 70 patients were included. In Group B, the mean operating time was less compared to Group A. The incidence of tracheal injury was also less when compared to previous data (pâ¯=â¯0.042). Mean OSATS score for flow of operation and overall performance was better in Group B (pâ¯=â¯0.002, pâ¯=â¯0.005). The OSATS score was also better for fifth and seventh case in Group B, proving its faster learning by trainee fellows. CONCLUSION: The technical modification decreases chances of tracheal injury and shortens the learning curve for upper pouch dissection. LEVEL OF EVIDENCE: Level III.
