Abstract

BERRIOS-MEJIA, Juan Alberto et al. Tracheal and laringo tracheal resection in tracheal stenosis: Predictors of postoperative recurrence. Neumol. cir. torax [online]. 2016, vol.75, n.4, pp.275-280. ISSN 0028-3746.

Background:

Tracheal resection and anastomosis is the gold standard for the treatment of tracheal stenosis. Restenosis is 5 to 22% of cases report, dehiscence stenosis occurs in about 4-7.5% and mortality is 1.8 to 5%. The objective of this study is to evaluate the restenosis after tracheal resection for benign stenosis and the predicting factors for such complications.

Material and methods:

A retrospective study was made involving patients with benign tracheal or laryngotracheal stenosis who underwent surgical resection and reconstruction between January 2008 and December 2012. Restenosis was studied. Categorical variables were presented as percentage and continuous variables as mean and standard deviation. Predicting factors were determined by logistic regression univariate and multivariate. Statistical significance was set for p less than 0.05.

Results:

155 patients (52 female, 103 male) were included. Complications occurred in 52 (33.5%). The most common complication was restenosis (21%). Laryngeal commitment and length greater than 4 cm resection were statistically factors for restenosis. Laryngeal commitment was the most significant factor and was highly associated with restenosis (odds ratio 2.9, CI 95%: 1.2-6.6, p: 0.01). At the end of the study, 146 patients (94.2%) were breathing normally. There was no mortality in this series.

Conclusions:

Restenosis was the most frequent complication in patients undergoing tracheal resection. Laryngeal commitment and length greater than 4 cm resection were statistically significant factors for the onset of restenosis.
