Minimally Invasive Component Separation in the Repair of Large Abdominal Wall Defects

  • Eva Barbosa
  • Fernando Ferreira


The minimally invasive component separation technique is a feasible and reproducible procedure that restores the abdominal midline in many large defects, helping to promote physiological abdominal reconstruction. It is of special use when dealing with a contaminated setting as it can lead to abdominal midline closure without applying prosthetic material. If complete midline restoration is not possible, component separation helps reduce the abdominal wall defect, decreasing the amount of prosthetic material necessary for a bridge repair, respecting as much as possible the physiology and kinetics of the abdominal wall. The minimally invasive component separation technique has many advantages over classic open techniques, avoiding large skin flaps and consequent problems related to wound healing. More studies are needed to compare different minimally invasive techniques regarding advancement of myofascial flaps and respective costs. In this chapter, we describe and illustrate in detail the video-assisted component separation technique and discuss special settings for its use, such as in the primary closure of the difficult open abdomen. Finally, it is fundamental to keep in mind that the minimally invasive component separation technique is only one helpful part in the puzzle involving large and complex abdominal wall defects. Proper planning and attention to details are important for successful achievement of closure.
