Elongation of esophageal segments by bougienage stretching technique for long gap esophageal atresia to achieve delayed primary anastomosis by thoracotomy or thoracoscopic repair: A first experience from China

Abstract

ObjectivesThe treatment of long gap esophageal atresia (LGEA) is one of the most challenging congenital malformations in neonatal surgery. A preoperative bougienage stretching technique for elongation of the two segments of esophagus is applied to achieve utilizing the native esophagus to establish esophageal continuity by open or thoracoscopic approach. MethodsFrom January 2015 to May 2017, 12 neonates who suffered from LGEA were admitted to our department. They were divided into 2 groups (A and B) according to their admission time. They all accepted bougienage stretching technique before esophageal anastomosis. ResultsInitially the lengths of esophageal gap in 12 infants ranged from 4 to 7.5 vertebral bodies (M=5.8±1.1). The gap lengths became –1 to 2.5 vertebral bodies after bougienage stretching technique and tension-free anastomosis were performed successfully for all 12 cases: Group A (n=5) by thoracotomy and group B (n=7) by thoracoscopic approach. 12 cases have been followed up for 1–25 months (M=12.4±8.5) after definitive surgery. ConclusionsBougienage stretching technique for LGEA is feasible with satisfactory clinical results. Thoracoscopic approach is a good choice for primary anastomosis in LGEA.
