Seven patients with thoracic esophageal cancer underwent thoracoscopic esophagectomy, which was successfully completed in all cases. In order to evaluate the procedure, intraoperative and postoperative courses were compared with those of the conventional esophagectomy through right thoracotomy (open technique). The total operating time of thoracoscopic esophagectomy was 6 hr 44 min ± 51 min (mean ± standard deviation). The operating time for thoracoscopy was 3 hr 20 min ± 12 min,which was significantly longer than that for the open technique.The total estimated blood loss was 191 ± 269 g and the estimated blood loss for thoracoscopy was 87 ± 182 g. There were no significant differences of blood loss from the open technique. Ventilatory support was required for 1.3± 0.8 days,the period of postoperative stay in the intensive care unit was 2.1 ± 1.1 days, and postoperative hospitalization was 50.1 ± 22.1 days for thoracoscopic esophagectomy. These results were significantly better than our previous experience with the open technique. There were no fatal postoperative complications. Thoracoscopic esophagectomy may be the preferred treatment for thoracic esophageal cacer.
