Aim of the study: The management of newborns with esophageal atresia (EA) and right aortic arch (RAA) is still an unsolved problem. This study provides a systematic review of epidemiology, diagnosis, management and short-term results of children with EA and RAA.
Materials and methods: The PubMed database was searched for original studies on children with EA and RAA. In each study, data were extracted for the following outcomes: number of patients, associated anomalies, type of surgical repair, morbidity and mortality rate.
Results: Eight studies were selected, including 54 patients with EA and RAA. RAA was encountered in 3.6% of infants. Preoperative detection of RAA was reported in 7 of them. In these patients, primary anastomosis was achieved through the right approach in 3 (thoracotomy in 2 and thoracoscopy in 1) while the left approach was the primary choice in 4 (thoracotomy in 2 and thoracoscopy in 2). No significant differences were found between the right and left approaches with regard to leaks (P=0.89), strictures (P=1) or mortality (P=1). In 47/54 patients (87%) RAA was noted during right thoracotomy, and primary anastomosis was achieved through the same approach in 29 (61.7%); conversion to other approaches (left thoracotomy or esophageal substitution) was performed in 15 children (38.3%). No significant differences were found between primary left thoracotomy (LT) and LT after RT with regard to leaks (P=0.89), strictures (P=1) or mortality (P=1).
Conclusions: Skills and preferences of the surgeon still guide the choice of surgical approach even when preoperatively faced with RAA. A multicenter, prospective randomized study is strongly required.
