Laparoscopically harvested omental flap for chest wall and intrathoracic reconstruction.

Minimally invasive surgery has gained popularity in the last decade and its applications to plastic surgery are expanding. Pedicled omental flaps are used for the reconstruction of chest wall defects following debridement of sternal infections and mediastinitis. The main advantages of using an omental flap are its large size and bulk to fill large 3-dimensional dead spaces, long pedicle, and rich vascular and lymphatic networks. Recently, laparoscopic techniques have been described for harvesting omental flaps. Over the last 5 years in our institution, 9 laparoscopic omental flap harvests were performed. Seven were used in the reconstruction of complicated chest wall defects, sternal infections, mediastinal abscesses, and mediastinitis following cardiac surgery. Two were used to repair intrathoracic viscera. Prior abdominal surgery was not a contraindication to the laparoscopic harvest. In 1 patient, the omental transfer was converted to a free flap due to the detachment of the pedicle, and in 1 patient the omental harvest was converted to open technique due to technical difficulty due to severe abdominal adhesions. None of the patients had major intraabdominal complications postoperatively. One patient had a small transdiaphragmatic hernia treated by laparoscopic techniques. The use of laparoscopy techniques facilitated the harvesting of the omentum, making it ideal in the treatment of complicated patients with multiple comorbidities. With these techniques, pedicled omental flaps will be a reasonable treatment option for chest wall reconstruction.
