Table 1 Case report timeline

Item		Timeline
Preoperative	1	Cough worsened and wheezing after exercise for more than 1 month
	2	No previous history of hypertension, diabetes, or coronary artery disease
	3	Enhanced CT of the chest and CT of the neck showed a rich blood supply occupying lesion in the esophageal travel area of the posterior superior mediastinum, considering an extraesophageal and intertracheal tumor lesion
	4	The surgery was performed under general anesthesia with static suction
Perioperative	5	After admission, the left upper extremity venous access was opened and BP, ECG, SpO2, and BIS were routinely monitored
	6	Invasive BP was monitored and arterial blood gas analysis was conducted
	7	Induction of conventional anesthesia; Maintenance of anesthesia was performed by static inhalation compound general anesthesia
	8	Airway tool of choice: Single-lumen tube with blocker. Single-lumen tube with blocker inserted under fibrinoscopic guidance
	9	During the free exploration of the tumor, the airway resistance increased abruptly, and emergency fibrinoscopy was performed. The operator adjusted the position of the tumor to restore airway patency and advanced the single-lumen tube under fibrinoscopic guidance to below the tumor
	10	Intraoperative, postoperative and before extubation, fibrinoscopy was used to detect an intact and uninjured airway
	11	After the operation, the vital signs were stable and there were no respiratory complications. He was returned to the ward
Postoperative	12	Vital signs were stable upon return to the room, with no respiratory complications
	13	The patient recovered well and was successfully discharged from the hospital
