DOZ047.124: Thoracoscopic anatomy of long-gap esophageal atresia. What can we predict?

Since the very beginning in 1999, thoracoscopic repair of esophageal atresia has become a gold standard in many pediatric surgery centers worldwide. Despite the advances in surgical technique, treatment of long-gap esophageal atresia still remains a challenge. The aim of this study is to assess whether the localization of esophageal stumps can predict number of stages needed to perform anastomosis. We analyzed video records of 21 patients who underwent staged thoracoscopic repair of long-gap esophageal atresia using internal traction technique. All procedures were performed by the same surgeon. We divided patients into two groups: first requiring single internal traction procedure, second who underwent multiple procedures. We assessed esophageal stump position in relation to thoracic vertebrae. The distance between stumps was measured in vertebral bodies. Mean distance between esophageal ends was 5.8 in single traction group. The distance between the stumps was significantly greater in multiple procedures group: 7.33 (P = 0.003). Patients who required multiple procedures had significantly lower localization of distal stump. Localization of proximal stump did not affect the possibility for anastomosis after single traction. Distance between both ends after internal traction was also significantly longer in multiple procedures group. Patients with lower localization of distal esophageal stump assessed during primary thoracoscopy are at higher risk for requiring multiple surgical procedures.
