Objective To statistical analyze the high-risk factors of recurrent tracheoesophageal fistula (RTEF) after the repair of type Ⅲ esophageal atresia and tracheoesophageal fistula (EA-TEF),and evaluate the ability of these high-risk factors predicting RTEF. Methods Retrospectively analyzed the clinical data of children with type Ⅲ EA-TEF in our hospital from September 2015 to January 2021. Patients were divided into two groups (recurrent and non-recurrent group,R and NR group) according to whether there was RTEF. The general situation of those patients, situation during surgery like open or thoracoscopic surgery,operation time,method of tracheoesophageal fistula ligation were compared. Those factors of two groups were analyzed, the high-risk factors of RTEF were summarized, and Logistic regression analysis on the high-risk factors was performed to analyze the ability of predicting RTEF. Results A total of 154 infants with type Ⅲ EA-TEF were included in the study, 98 males, 56 females. There were 11 cases in R group, 143 cases in NR group. Univariate comparative analysis was carried out on R group and NR group, and no statistical differences were found except in anastomotic fistula. There were 6 patients in R group with anastomotic fistula, accounting for 54.55%, and 13 patients in NR group, accounting for 9.10%,P< 0.001. After adjusting the Logistic regression model with the high-risk factors, there was 12-fold increase in the risk of RTEF with anastomotic fistula (OR=12.000, 95%CI: 3.216~44.771) compared with no anastomotic fistula. Conclusion RTEF was not related to patients' general situation or surgery situation, but significantly related to anastomotic fistula. Patients who with anastomotic fistula had a 12-fold increase in the risk of RTEF compared with no anastomotic fistula.
