BACKGROUND: The ideal reconstructive procedure after sternal debridement is still a matter of debate. The omentum might be theoretically preferable for its favorable properties, but it is seldom used because it entails the added trauma of a laparotomy.

METHODS: Three female patients with severe osteomyelitis after myocardial revascularization underwent sternal debridement and filling of the defect with a laparoscopically prepared omental flap. Sternal wound closure was achieved as a single-stage procedure in 2 patients. The third patient had a poststernotomy septicemia and required a 2-stage procedure. The abdominal procedures were conducted through 3 operating 5-mm ports. Omental flaps were developed by complete separation from the transverse colon and lengthening by division of some anastomosing arteries between gastroepiploic vessels and Barkow’s arcade. Thoracic transposition of the omentum was achieved through a 5-cm diaphragmatic incision. The flaps were able to reach the base of the neck and fill the sternal defect in all patients.

RESULTS: A smooth postoperative course was observed. Oral intake was started from day 2; sole oral nutrition was maintained from day 3 or 4. Optimal wound healing was observed with minimal or absent local discomfort. Minor transient paradoxical movements of the anterior chest wall disappeared within 1 month. Postoperative hospital stay was 9, 14, and 14 days, respectively.

CONCLUSIONS: Laparoscopic omentoplasty, compared with the open procedure, entails several advantages for the treatment of sternal osteomyelitis. The introduction of minimally invasive techniques may widen the indications for the use of the omentum in the treatment of major sternal wound infections.
