Risks and benefits of using Marlex mesh in chest wall reconstruction
1Reconstructive Plastic Surgery Service, University of Texas M. D. Anderson Cancer Center 77030.
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.
Insights
Marlex mesh stabilization in chest wall reconstruction significantly reduces ventilator dependence and hospital stay. This synthetic mesh use does not substantially increase infection risk when tissues remain viable.
Area of Science:
- Thoracic surgery
- Biomaterials science
- Surgical outcomes research
Background:
- Chest wall reconstruction is critical for patients with significant defects.
- Stabilization techniques aim to improve respiratory mechanics and reduce complications.
- Marlex mesh is a synthetic material used for structural support in reconstructive surgery.
Purpose of the Study:
- To evaluate the efficacy of Marlex mesh in reducing ventilator dependence and hospital stay after chest wall reconstruction.
- To determine if Marlex mesh use is associated with an increased risk of surgical site infections.
- To assess the impact of Marlex mesh on chest wall stability.
Main Methods:
- Retrospective review of 101 patients undergoing chest wall reconstruction.
- Comparison of outcomes between patients with and without Marlex mesh stabilization.
- Analysis of ventilator support duration, hospital length of stay, and infection rates.
Main Results:
- Patients with Marlex mesh had significantly shorter ventilator support (0.8 vs 4.9 days, p=0.03) and hospital stays (9.7 vs 17.5 days, p=0.006).
- Wound infections occurred in 5% of the Marlex group, associated with flap necrosis, versus 0% in the non-Marlex group (not statistically significant).
- Marlex mesh provided improved chest wall stability, reducing ventilator dependence and hospital stay.
Conclusions:
- Marlex mesh is effective in improving chest wall stability, reducing ventilator dependence and hospital stay in reconstruction.
- The risk of wound infection is not significantly increased with Marlex mesh use, provided adequate tissue vascularization.
- Proper surgical technique and patient selection are crucial to mitigate potential complications like flap necrosis.
