title: [Simulation of thoracoscopic esophagectomy for esophageal cancer by three-dimensional computed tomography and usefulness for preservation of bronchial arteries].
abstract: Thoracoscopic esophagectomy for esophageal cancer was simulated preoperatively by 3-dimensional computed tomography (3D-CT). The anatomical structures such as major vessels, bone, trachea and bronchi, esophagus, lymph nodes, and broncial arteries were extracted from multi-detector row CT scanning and integrated to build the virtual operative field by multi-volume fusion. The virtual thoracoscopy was helpful to understand the location of lymph nodes and bronchial arteries in relation to the adjacent anatomical structures. Preservation of bronchial arteries is important to avoid tracheobronchial ischemia which is a fatal complication in salvage esophagectomy after definitive chemoradiotherapy. 3D-CT revealed anatomical variations of bronchial arteries and was useful for identification and preservation of bronchial arteries in thoracoscopic esophagectomy.
