Segmental tracheal resection and anastomosis for the treatment of cicatricial stenosis in cervical tracheal

Abstract

To evaluate the efficacy of segmental tracheal resection with end-to-end anastomosis for cicatricial cervical tracheal stenosis. The clinical outcomes of 40 patients treated with tracheal resection were retrospectively reviewed. There were 28 male patients and 12 female patients with the age ranged from 6 to 64 years (mean 33.7 years). The degree of stenosis was classified according to Myer-Cotton classification as follows: grade Ⅱ (n=7), grade Ⅲ (n=22) and grade Ⅳ (n=11). The stenosis extension ranged from 1.0 to 4.3 cm (mean 2.5 cm). The causes of the stenosis were postintubation (n=33), cervical trauma (n=6) and resection of tracheal neoplasm (n=1). Thirty-four(85.0%) patients were decannulated and 6 failed. Of the 6 patients failed, 4 were decannulated after reoperation with the sternohyoid myocutaneous flap or thyroid alar cartilage graft. Complications occurred in 10 patients. In 8 patients granulation tissues formed at the site of the tracheal anastomosis, which needed endoscopic resction, and in 2 patients anastomosic dehiscence occurred. No injury to recurrent laryngeal nerve or trachoesophageal fistula occurred. Segmental tracheal resection with end-to-end anastomosis is an effective surgical method for tracheal stenosis, which has a higher successful rate for primary operation and shorter therapeutic period.
