Abstract
OBJECTIVES: Anastomotic airway complications give rise to morbidity and mortality after lung transplantation. Knowledge about contributing factors helps in adopting diagnostic and therapeutic strategies. Systematic endoscopic description and classification play a key role. METHODS: A retrospective analysis of all bronchial anastomoses between 2005 and 2013 was performed to assess anastomotic complications and associated variables. Treatment modalities and outcome of endobronchial and surgical interventions are reported. RESULTS: The prevalence of anastomotic airway complications in our cohort was 11%. Contributive factors were all recipient-dependent: microbial infection during the first postoperative trimester [odds ratio (OR) 3.4 (2.1-5.5); P < 0.0001], recipient age [OR 3.0 (1.3-7.1); P = 0.01], right-sided anastomosis [OR 2.5 (1.4-3.3); P = 0.001], the presence of microbiological colonization prior to transplantation [OR 1.8 (1.1-3.1); P = 0.02] and [Formula: see text] during the first 72 h after transplantation [OR 1.6 (1.1-2.7); P = 0.04]. Seventy-five percent of cases were managed conservatively, of which 93% evolved clinically favourable during follow-up. Our data support the use of the proposed MDS classification and show that MDS class M3b, D2x, Sxe or higher are associated with an increased intervention rate. CONCLUSION: Anastomotic airway complications remain an important issue after lung transplantation. The identified risk factors may play a role in the pathophysiology of anastomotic complications. The indication for endobronchial intervention should be carefully considered based on endoscopic classification since most cases resolve or stabilize over time.
