The goal of this clinical trial is to investigate whether the use of bronchial blocker could reduce the incidence of postoperative vocal cord palsy than the use of double-lumen endobronchial tube in robot-assisted esophagectomy.

bronchial blocker
DeviceLung isolation for robot-assisted esophagectomy will be performed using bronchial blocker in this group.
double-lumen endobronchial tube
DeviceLung isolation for robot-assisted esophagectomy will be performed using double-lumen endobronchial tube in this group.
Postoperative vocal cord palsy
On postoperative day 7, ENT doctor will performed the laryngoscopy exam to check the presence of vocal cord palsy.
Number of resected recurrent laryngeal nerve lymph nodes
Number of successfully resected recurrent laryngeal nerve lymph nodes will be counted at the end of surgery
Quality of one lung ventilation
during one lung ventilation, anesthesiologists will evaluate the degree (excellent, fair, poor) of lung collapse.
Surgical difficulty reported by surgeon
Surgeon will report the surgical difficulty (easy, moderate, difficult).
