[Reconstruction of a thoracic wall defect using a flap of omentum obtained by laparoscopy]. / Obtenção de retalho de epíplon por via laparoscópica para reconstrução de defeito da parede torácica.

ABSTRACT

Reconstructive of complex chest wall defects following infected sternotomy represents a surgical challenge. Several options were described for these defects reconstructions, using muscles flaps and omentum which provided obliteration of dead space and coverage. We present a reconstruction of a major chest and abdominal wall defect in a 62-year old patient, who had mediastinitis, osteomyelitis and necrosis of sternum after myocardial revascularization. The pectoralis major was used unsuccessfully, with total loose of the flap. After wound failure, a flap of omentum based on the left gastroepiploic vessels was obtained by a laparoscopic surgery, with no complication. The omentum was translocated through the defect that reached the abdominal wall covering the defect and allowing the use of split-thickness grafts. The laparoscopic procedure showed advantages over the laparotomy in the management of omentum, with the same results in the reconstruction of the defect added the advantages of a minimal invasive procedure, mainly in patient with bad clinical conditions.
