[Treatment of laryngotracheal and tracheal cicatricial stenosis: 10-year experience].

OBJECTIVE

To describe 10-year experience of treating the cicatricial tracheal stenosis (CTS) in a regional multi-field hospital.

MATERIAL AND METHODS

There were 120 CTS patients aged 13-75 years. In 8 (6.7%) patients, CTS was combined with tracheoesophageal fistula (TPF). Post-intubation stenosis was diagnosed in 16 (13.3%) cases, post-tracheostomy - in 102 (85%) ones, post-traumatic - in 2 (1.7%) patients. CTS length ranged from 1.2 to 8 cm. Fifty (41.7%) patients had cervical CTS, 40 (33.3%) patients - cervico-thoracic tracheal stenosis, 11 (9.2%) patients - tracheal stenosis at the thoracic level. Nineteen (15.8%) patients had multifocal stenoses. We used endoscopic techniques, circular tracheal resection (CTR) and laryngotracheal reconstruction.

RESULTS

Postoperative mortality rate was 0.83%. CTR was performed in 33 patients, laryngotracheal reconstruction - 77, endoscopic stenting - 6 patients. In 4 cases, local CTS was eliminated by bougienage and argon plasma exposure. CTS was successfully disconnected with TEF using CRT in 3 cases, laryngotracheoplasty and stenting - in 5 cases. The fenestrated tracheal defect was closed by a three-layer autologous flap in 59 patients. Of these, autologous flap was reinforced with porous nickel-titanium implants in 17 patients. Postoperative complications after CRT occurred in 6 (16.7%) patients (anastomotic leakage - 2, anastomositis - 1, restenosis - 2). No patients died. Postoperative complications after laryngotracheal reconstruction were observed in 18 (23.4%) patients including 5 ones with restenosis who underwent CTR with a favorable outcome.

CONCLUSION

CTS treatment requires a multidisciplinary approach. Each surgery has certain indications and place in treatment algorithm. CTR is highly effective, but may be accompanied by complications associated with tracheal anastomosis. Decrease of postoperative morbidity will improve immediate and long-term results of CTS treatment. The chosen treatment algorithm ensured good and satisfactory results in 98% of patients.
