“…Although a comparative analysis among different prosthetic materials was not investigated, these data are similar to those reported by Macedo-Neto et al: in fact, after surgical repair with mesh, despite elastic changes and an increase of pressure dissipated against viscoelastic/inhomogeneous segments of the CW, the PTFE patch (non-rigid prosthesis) seems to induce less important mechanical modifications than the Marlex mesh associated with MMA (rigid prosthesis), thus, better conveying the restoration of physiologic function. 19 These results should also be taken into account when the effects of CW instability on postoperative ventilation are considered. In literature, in fact, there are few reports on the need for ventilator support after CW stabilization with mesh.…”

BackgroundTo address the question of how much chest-wall (CW) resections and prosthetic reconstructions influence functional outcome.MethodsWe retrospectively reviewed 175 patients who underwent surgery for CW tumors. The clinical, histological, surgical, oncological, and functional factors were analyzed.ResultsWe performed: 75 rib resections; 20 sternal resections; 15 combined resections; and 27 lung resections. In 39 cases (22.2%) CW was stabilized with non-rigid prosthesis (Vicryl-mesh: 8 patients; Goretex-mesh: 31 patients). Postoperative complications occurred in 22 cases (12.6%): a correlation with lung resection was evidenced by multivariate analysis (P = 0.025). Five-year survival for primary and secondary tumors was 50% and 36%, respectively: multivariate analysis (P = 0.048) showed a worse survival in men only. In the prosthesis subset, pulmonary function tested as percentage of forced expiratory volume in one second (%FEV1) (pre: 87.1 ± 18.9%; post: 82.3 ± 23.0%, P = ns), percentage of forced vital capacity (pre: 94.1 ± 19.3%; post: 82.0 ± 21.6%, P = ns), diffusing capacity of the lungs for carbon monoxide (pre: 15.7 ± 7.4; post: 12.1 ± 4.1, P = ns) and paO2 (pre: 82.6 ± 10.9 mmHg; post: 83.9 ± 7.3 mmHg, P = ns) was slightly modified from pre to postoperative. Interestingly, the decline of FEV1% was lower in the prosthesis-subset (4.1 ± 15.9%) compared with the subgroup who did not undergo prosthetic stabilization (17.5 ± 16.2%), but this difference was not statistically significant (P = ns).ConclusionBecause of the low decrease of lung parameters, CW prosthetic reconstruction could be helpful for avoiding postoperative worsening of functional outcome, mostly in patients with pre-existing pulmonary diseases.

“…A different variant often used in thoracic wall reconstruction techniques are PTFE (polytetrafluoroethylene) meshes (Gore-Tex). It presents the advantage of having a fairly high resistance whiteout having the rigidity of the titanium or methyl-methacrylate plates [27,28]. A major advantage of Gore-tex meshes is their impermeability to liquids and air.…”

The thoracic wall resections for tumoral affections are laborious surgical interventions characterized by a high mortality and mobility. In order to create this paper we created a observational retrospective study in which we included 21 patients that have underwent parietal thoracic resections for tumoral affections. In all the patients we practiced the reconstruction of the thoracic wall using polypropylene mesh. The main postoperative complications were: seromas (14.28% of the cases), hematomas (9.52% of the cases), wound infection (4.76% of the cases), pneumonia (23.8% of the cases), respiratory failure (23.8% of the cases), paradoxical movement of the thoracic wall (52.38% of the cases). No deceases were recorded. In conclusion, the use of polypropylene mesh in the reconstructive techniques of the thoracic wall after thoracic wall resection represents a viable method, with good respiratory functional results.

“…For example, the research of Macedo-Neto found that methylmethacrylate greatly impacted the dynamics of chest wall movement [25]. Further, the methylmethacrylate located in the middle of the 'sandwich' was very hard and lacked flexibility.…”
