Omental flap obtained by laparoscopic surgery for reconstruction of the chest wall.

The reconstruction of complex defects of the chest wall after infection of the sternotomy wound presents a great challenge. Various options have been described for these reconstructions using muscle and omental flaps to fill the space and cover the defect. A case of reconstruction of a large defect of the chest cage and abdominal wall in a 62-year-old patient is presented. After surgery for revascularization of the myocardium, the patient developed mediastinitis, osteomyelitis, and necrosis of the sternum. The pectoralis major muscle was utilized for the reconstruction, but total loss of the flap occurred. After débridement, an omental flap obtained by laparoscopy was employed based on the left gastroepiploic artery. The omentum was transposed without complications through the abdominal wall defect. An overlay skin graft with the omentum as receptor bed completed the closure. There are advantages in using minimally invasive videolaparoscopy compared with laparotomy in obtaining the omentum, with the same result regarding reconstruction of the defect.
