Background:  Thoracoscopic repair of esophageal atresia (EA) with tracheoesophageal fistula (TEF) is becoming an increasingly widespread technique; there is still controversy about its indication in certain patients. Our objective is to analyze if potential risk factors such as major congenital heart disease (CHD) or low birth weight (LBW) are a limitation to this approach., Methods:  Retrospective study (2017-2021) of patients with EA and distal TEF who underwent thoracoscopic repair were included. Patients with LBW less than 2,000 g or major CHD were compared with the rest., Results:  Twenty-five patients underwent thoracoscopic surgery. Nine patients (36%) had major CHD. Five of them (20%) were LBW less than 2,000 g, and only 8% (2/25) presented both risk factors. There were no differences in terms of operative time, conversion rate, tolerance evaluated with gasometric parameters (pO 2 , pCO 2 , pH) or complications (anastomotic leak and stricture, both early or during follow-up) in patients with major CHD and LBW (1,473 ± 319 vs. 2,664 ± 402 g). One conversion to thoracotomy was performed in a neonate weighing 1,050 g due to anesthetic intolerance. There was no recurrence of TEF. One patient died at the age of 9 months, due to major uncorrectable heart disease., Conclusion:  Thoracoscopic repair of EA/TEF is feasible technique in patients with CHD or LBW, with similar results to other patients. The complexity of this technique warrants individualizing the indication in each case., Level of Evidence:  IV., Competing Interests: None declared., (Thieme. All rights reserved.)

Aim: The optimum surgical approach of neonates with right-sided aortic arch (RAA) and esophageal atresia (EA)/tracheoesophageal fistula (TEF) is still an unsolved question. In order to propose an operative algorithm in the era of endoscopic surgery, we performed an international survey to know the current practice between pediatric endoscopic surgeons. Two of the most important societies in endoscopic pediatric surgery were queried: the International Pediatric Endosurgery Group (IPEG) and the European Society of Paediatric Endoscopic Surgeons (ESPES)., Materials and Methods: During December 2016, an anonymous online-based survey was sent to all IPEG and ESPES members, collecting data regarding perioperative management and surgical repair of EA/TEF with RAA., Results: 144 surgeons from 23 countries completed the questionnaire. 69.2% of respondents were IPEG members, 30.8% were ESPES members. 71.5% of members who answered the survey had more than 10years of surgical experience. A preoperative echocardiography was almost uniformly performed (93.1%). 31.9% of the surveyed surgeons had never treated an EA/TEF with RAA. The remaining 98 surveyed surgeons had managed 279 cases of EA/TEF with RAA. Thoracotomy was considered the preferred approach for 54.2% of the surgeons, and 51.9% chose a right-sided approach. When RAA was an intraoperative finding, 76% would perform a contralateral thoracotomy if difficulties arose. Thoracoscopy was preferred by 45.8% of surgeons. If RAA was suspected preoperatively, 63.1% preferred to attempt a left-sided thoracoscopy and only 24.2% would change their approach to a thoracotomy. If RAA was an intraoperative finding and a safe surgical repair could not be achieved through right-sided thoracoscopy, 51.5% of them chose to perform a left sided thoracoscopy, rather than convert to thoracotomy., Conclusions: Preoperative echocardiography performed by experienced examiners helps in surgical planning. Preoperative diagnosis of RAA should not discourage thoracoscopic repair, which is increasingly becoming more popular for the correction of EA/TEF. In case of an unexpected intraoperative diagnosis of RAA or operative difficulties when approaching through the right side, thoracoscopy offers a less aggressive approach., Level of Evidence: V., (Copyright © 2017 Elsevier Inc.
