Synthetic and biological mesh in component separation: a 10-year single institution review.

Definitive repair of recurrent ventral hernias using abdominal wall reconstruction techniques is an essential tool in the armentarium for general and plastic surgeons. Despite the great morbidity associated with incisional hernia, no consensus exists on the best means for treatment (Korenkov et al, Langenbecks Arch Surg. 2001;386:65-73). Ramirez et al (Plast Reconstr Surg. 1990;83:519-526) describes the "component separation" technique to mobilize the rectus-abdominus internal oblique and external oblique flap to correct the defect. This retrospective institutional study reviewed 10 years of myofascial flap reconstruction from 1996 to 2006 at Thomas Jefferson University Hospital and revealed an 18.3% recurrence rate in 545 component separations. We identified obesity (body mass index >30 kg/m2), age >65 years old, male gender, postoperative seroma, and preoperative infection as risk factors for hernia recurrence.
