Abstract
A tracheoesophageal fistula (TEF) associated with complete tracheal rings (CTR) is extremely rare. This study aimed to elucidate the clinical features of this combination. Records of 39 patients diagnosed with TEF with or without CTR between January 2013 and February 2023 were retrospectively reviewed. Data collected included location of the TEF and CTR, esophageal gap, surgery of TEF/esophageal atresia (EA), and symptoms of CTR. Seven patients had CTR, while 32 patients did not have CTR. TEF was frequently located higher than the T4 vertebra, and the median esophageal gap was shorter in patients with CTR than in those without (5/7 [71.4%] vs. 6/32 [18.8%], P = 0.012; 0 (range: 0-15) mm vs. 13.3 (range: 0-40) mm, P = 0.017, respectively). TEF was located just above the beginning of the CTR in all patients. All patients with CTR underwent primary esophageal anastomosis. Additionally, two patients were diagnosed with CTR before TEF/EA repair. A tracheal tube was prevented from contacting the CTR during TEF/EA repair, and respiratory insufficiency did not occur. Our results may help pediatric surgeons in the management of TEF with CTR.
