Abstract: Objective To investigate the perioperative complications and treatment methods of total en bloc spondylectomy(TES) in the treatment of spinal tumors. Methods A total of 32 patients with spinal tumors, who received TES therapy in Sun Yat-Sen University Cancer Center from January 2017 to February 2020, were collected to observe the occurrence and outcome of intraoperative and post-operative complications. Results All the 32 patients completed the operation successfully. The operation time was (298.21±53.31) min (range: 260-380 min), and the intraoperative blood loss was (2 412.45±316.56) mL (range: 1 850-3 200 mL). On the first day after the operation, the Frankel grade of 2 patients increased from preoperative Grade E to Grade C, 3 patients improved from preoperative Grade C to Grade D, and the remaining 27 patients remained unchanged. There was no significant difference in Frankel classification between preoperative and postoperative patients(Z=-1.526, P=0.075). The total incidence of perioperative complications was 43.8% (14/32), all of which turned out to be good after symptomatic treatment and no fatal complications occurred. Conclusion The inci-dence of complications during the perioperative period of total spinal mass resection for spinal tumors is relatively high, which can be alleviated by timely and effective treatment, and the incidence of fatal complications is low.
