title: [The optimal procedure for chylothorax after operation for thoracic esophageal cancer; reasonable approaches to the thoracic duct from the point of view of routes for esophageal replacement].
abstract: In general, chylothorax after esophagectomy with lymph node dissection under thoracotomy is a rare postoperative complication. We report a 71-year-old man who developed chylothorax following esophagectomy and 3-field lymph node dissection together with reconstruction using stomach through the posterior mediastinum, and discuss ideal approaches that are less invasive and make it possible to provide better exposure of the thoracic duct. In selecting the ideal approach, the most important thing is differences in routes for esophageal replacement. The anatomical relation between the location of a conduit adopted for reconstruction of the resected esophagus and the thoracic duct should be considered in each case. In the case of the retrosternal or antesternal route, a video-assisted thoracoscopic approach allows for easy detection of the thoracic duct while reducing surgical invasiveness, because there is no conduit in the posterior mediastinum. On the other hand, a conduit interrupts the visual field of thoracoscopy in the case of the posterior mediastinal or intrathoracic route. Drawing up of a conduit to gain a good operative field involves some risks in protection of the vascular pedicle. Therefore, a transabdominomediastinal approach is an optimal option. With this approach, we could easily find the thoracic duct and directly ligate it just cranial to the hiatus, resulting in a remarkable decrease in discharge through the thoracic drainage tube. In addition, we present an intelligible intraoperative photograph.
