Abdominal wall defects: anatomic classification and a scheme for management.

Abstract

Defects created after excision of abdominal wall tumors pose a challenge to the reconstructive surgeon. The task is made more difficult by the wide variety of flaps available for this purpose. We present a simple classification of abdominal wall defects and our choice of flaps for reconstruction. The abdomen was divided into six regions for the purpose of reconstruction. The deep inferior epigastric artery flap alone is the flap of choice for central supraumbilical defects. For lateral supraumbilical defects the latissimus dorsi flap fulfills all the requirements. Infraumbilical defects, central or lateral, are ideally suited to reconstruction by unilateral or bilateral tensor fascia lata flaps. Patients representing each scenario are presented.
