Abdominal wall, anatomy, incisional hernia.Abstract
Introduction: the anterolateral abdominal wall includes 4 muscles: external oblique, internal oblique, transverse abdominis and rectus abdominis, which allow it to participate in diverse functions. These can be affected by an incisional hernia. When they achieve huge size, its repair may represent great challenge to the general surgeon. Eventhroplasty using non-absorbable mesh is the gold standard treatment, but it can require additional procedures. Component separation technique is a group of anatomic-based procedures which allow the increase of abdominal volume. The aim of this report was to reproduce the component separation technique in cadaveric material, and a literature review. Materials and Methods: two adult cadavers of both sexes were used, fixed in formaldehyde. The external oblique muscle was liberated as described in the anterior component separation technique. Posterior component separation was made through a retro-rectal plane, and then progressing the dissection laterally. Results: Medial advancement of the muscles was achieved. Conclusions: knowledge of anterolateral abdominal wall anatomy is the basis for performing component separation technique. Training on cadaveric material is one of the first steps for surgical training.
