Expanded Polytetrafluoroethylene Mesh in Chest-wall Reconstruction: A 27-year Experience
The Journal of Thoracic and Cardiovascular Surgery(2024)
Abstract
Objectives
To evaluate the success of expanded polytetrafluoroethylene (ePTFE) mesh in chest-wall reconstruction.
Methods
We retrospectively reviewed patients who underwent ePTFE (Gore-Tex®) chest-wall reconstruction. The main outcome was a mesh-related event, defined as a mesh-related reoperation (e.g., mesh infection requiring debridement with/without explant, tumor recurrence with explant) and/or structural dehiscence/mesh loosening with/without a hernia. Demographics and surgical outcomes were reported.
Results
246 reconstructions met inclusion (1994-2021). Fifty-five (22.4%) reconstructions had mesh-related events within a median of 1.08 years (IQR 0.08, 4.53) postoperatively; those without had a stable chest for a median of 3.9 years (IQR, 1.59, 8.23, p<0.001). Forty-one (16.6%) of meshes became infected, requiring reoperation. Eighty-eight percent (36/41) were completely explanted; 8.3% (3/36) required additional mesh placement. Predictors of mesh-related events were prior chest-wall radiation (OR=9.73, CI 3.47 to 30.10, p<0.001), higher BMI (OR 1.08, CI 1.01 to 1.16, p=0.019), and larger defects (OR 1.48, CI 1.02 to 2.17, p=0.042). The risk of mesh-related events with obesity was higher with prior chest-wall radiation.
Conclusions
Most (78%) patients with an ePTFE mesh had a stable reconstruction after a median of 4 years. Obesity, larger defects, and prior chest-wall radiation were associated with a higher risk of a mesh-related event mostly due to mesh infections. Seventeen percent of reconstructions had reoperation for mesh infection; 88% were completely explanted. Only 8% required replacement mesh, suggesting that experienced surgeons can safely manage them without replacement. Future studies should compare various meshes for high-risk patients to help guide the optimal mesh selection.
