Mortality after sternal reconstruction with pectoralis major flap vs omental flap for postsurgical mediastinitis: A systematic review and meta-analysis. Review uri icon

Overview

abstract

  • BACKGROUND: Deep sternal wound infections are rare but severe complications after median sternotomy and can be managed with sternal reconstruction. The use of pectoralis major flap (PMF) has traditionally been the first-line approach for flap reconstruction but the advantage in patients' survival when compared to the omental flap (OF) transposition is still not clear. We performed a study-level meta-analysis evaluating the association of the type of flap on postoperative outcomes. METHODS: A systematic search of the literature was performed to identify all studies comparing the postoperative outcomes of PMF versus OF for sternal reconstruction. The primary outcome was postoperative mortality. Secondary outcomes were the occurrence of sepsis, pneumonia, operative time, and length of stay. Binary outcomes were pooled using an inverse variance method and reported as odds ratio (OR) with corresponding 95% confidence interval (CI). Continuous outcomes were pooled using an inverse variance method and reported as standardized mean difference (SMD) with corresponding 95% CI. RESULTS: Four studies with a total of 528 patients were included in the analysis. Overall, 443 patients had PMF reconstruction, and 85 patients had OF reconstruction. Baseline characteristics were similar in both groups. There were no statistically significant differences between PMF patients and OF patients in mortality (OR 0.6 [0.16; 2.17]; p = .09), sepsis (OR 1.1 [0.49; 2.47]; p = .43), pneumonia (OR 0.72 [0.18; 2.8]; p = .11), length of stay (SMD -0.59 [-2.03; 0.85]; p < .01), and operative time (SMD 0.08 [-1.21; 1.57]; p < .01). CONCLUSION: Our analysis found no association between the type of flap and postoperative mortality, the incidence of pneumonia, sepsis, operation time, and length of stay.
