  • Title: Risks and benefits of using Marlex mesh in chest wall reconstruction.
    Author: Kroll SS, Walsh G, Ryan B, King RC.
    Journal: Ann Plast Surg; 1993 Oct; 31(4):303-6. PubMed ID: 8239427.
    Abstract:
    The records of 101 patients who had undergone chest wall reconstruction both with and without stabilization of the chest wall by Marlex mesh were reviewed to see if Marlex reduced ventilator dependence and hospital stay, and to determine whether the use of Marlex was associated with any increased risk of infection. In 40 patients in whom Marlex was used, the mean number of days on postoperative ventilator support was 0.8, and mean hospital stay was 9.7 days. In 61 patients in whom Marlex was not used, the mean number of days on ventilator support was 4.9, and mean hospital stay was 17.5 days. These differences were statistically significant (p = 0.03, p = 0.006). Two patients in the Marlex-stabilized group (5%) developed wound infections, but these were preceded by ischemic necrosis of overlying flaps. None of the patients without Marlex developed wound infections. That difference was not statistically significant. We conclude that the use of Marlex in chest wall reconstruction does not significantly increase the risk of wound infection, provided that overlying tissues are properly vascularized and remain viable, and that synthetic mesh does improve chest wall stability and reduce ventilator dependence and overall hospital stay.
