Laparoscopic Greater Omentum Harvesting with Split-Thickness Skin Grafting for Sternal Wound Dehiscence

Abstract

Sternal wound dehiscence is a serious complication occasionally requiring soft tissue coverage. The greater omentum typically has been used as a last resort because of the underlying morbidity from a laparotomy. We present a case in which a laparoscopically created omental flap with subsequent split-thickness skin grafting was used to correct a large soft tissue defect that occurred after sternal wound dehiscence developed. A nonambulatory 49-year-old man who underwent coronary artery bypass grafting developed sternal wound dehiscence. Because a large soft tissue defect developed after multiple debridements, soft tissue coverage was required. A laparoscopically harvested omental flap spared this man's upper extremity musculature and provided a soft tissue bed for split-thickness skin grafting. This case helps to establish the role of laparoscopically harvested omentum. If the results suggested by this case are confirmed in a large series, omental flaps should be considered as options of first choice in the management of sternal wound dehiscence.
