Component Separation: Outcomes and Complications
- 939 Downloads
The introduction of the anterior component separation operation has facilitated our ability to close complex defects of the anterior abdominal wall. This classic operation was first described by Ramirez et al. in 1990 and has revolutionized hernia repair. With the evolution of hernia repair techniques, the use of mesh to further support the repair has demonstrated success. This mesh can be biologic, synthetic, or resorbable and can be placed in various layers that include onlay, underlay, retrorectus, as well as fascial interposition/bridge. The anterior component separation can also be performed as a minimally invasive technique or laparoscopically. Another recently described method is the “sandwich” technique whereby a classic component separation is performed followed by bilaminar mesh reinforcement as an underlay/retrorectus and onlay (Morris and LeBlanc, Hernia 17:45–51, 2013). This chapter will include a description of the various types of component separation repairs with an emphasis on outcomes and complications.
