The largest report on thoracoscopic surgery for recurrent tracheoesophageal fistula after esophageal atresia repair.

BACKGROUND

Although thoracoscopic surgery has become the routine surgical method for esophageal atresia/tracheoesophageal fistula (EA/TEF), thoracoscopic treatment for recurrent tracheoesophageal fistula (rTEF) is far from popularized.

OBJECTIVES

We aimed to explore the safety and efficacy of thoracoscopic treatment for rTEF with a large-cohort study.

METHODS

We retrospectively analyzed the clinical characteristics and outcomes of 103 consecutive patients who underwent thoracoscopic surgery for rTEF by one surgeon after EA/TEF repair at two different institutions in China from 2014 to 2021.

RESULTS

One hundred and three pediatric patients (67 boys) were enrolled and the primary operations were performed via thoracoscopic (n = 75, 72.82%) or open surgery (n = 28, 27.18%). The median age at rTEF diagnosis was 5 (3, 10) months after the primary repair. Patients were diagnosed with recurrent fistula to the trachea (n = 97, 94.17%), bronchi (n = 4, 3.88%), and lung parenchyma (n = 2, 1.94%), and all of them underwent thoracoscopic surgery at a median age of 7 (5, 14) months with a median weight of 6200 (4870, 7650) g. After the repair of rTEF, the incidence of esophageal leakage, esophageal stricture, and TEF recurrence were 12.8%, 33.4%, and 10.8%, respectively. After the follow-up, 87 patients survived, 6 died, and 10 were lost to follow-up.

CONCLUSIONS

The results of thoracoscopic surgery for rTEF were comparable with previously reported thoracotomy surgery. Owing to the clear field during the operation, rapid patient recovery and esthetic results, the thoracoscopic approach could be a better choice for experienced pediatric surgeons.
