What is Laparoscopic Versus Open-component Separation: a Comparative Analysis in a Porcine Model about?

## Background: The ideal surgical treatment for complicated ventral hernias remains elusive. traditional component separation provides local advancement of native tissue for tension-free closure without prosthetic materials. this technique requires an extensive subcutaneous dissection with division of perforating vessels predisposing to skin-flap necrosis and complicated wound infections. a minimally invasive component separation may decrease wound complication rates; however, the adequacy of the myofascial advancement has not been studied. ## Methods: Five 25-kg pigs underwent bilateral laparoscopic component separation. a 10-mm incision was made lateral to the rectus abdominus muscle. the external oblique fascia was incised, and a dissecting balloon was inflated between the internal and external oblique muscles. two additional ports were placed in the intermuscular space. the external oblique was incised from the costal margin to the inguinal ligament. the maximal abdominal wall advancement was recorded. a formal open-component separation was performed and maximal advancement 5 cm superior and 5 cm inferior to the umbilicus was recorded for comparison. groups were compared using
