[Segmental tracheal resection for the treatment of tracheal stenoses].

BACKGROUND

Segmental tracheal resection is considered to be the standard treatment of tracheal stenoses.

MATERIALS/METHODS: During the time period 1985-2002, segmental tracheal resection with a primary end-to-end anastomosis was performed in 117 patients with a cervical or upper thoracal stenosis of the trachea. The age distribution of the patients was between 7 and 77 years. Of the patients with a benign tracheal stenosis, sufficient data for a retrospective analysis were available in 101 patients. The length of the resected tracheal segments varied between 2 and 6 cm which required mobilisation of the trachea and the larynx and, if necessary, incision of the pulmonary ligament.

RESULTS

In 5 patients a permanent damage of the recurrent laryngeal nerve was seen, of which 4 had undergone revision surgery and 10 months after surgery 93% presented with a large and stable tracheal lumen without any relevant restenosis. Due to a restenosis of 70-80% causing dyspnea at rest, 3% of the 101 patients had to undergo revision surgery. In 4% a mild and asymptomatic restenosis of 30-40% was seen which did not require any further treatment.

CONCLUSION

These results demonstrate that segmental tracheal resection can safely and effectively remove stenotic tracheal segments of up to 6 cm and is therefore the treatment of choice.
