A minimally invasive component separation may lead to a dynamic abdominal wall after hernia repair, with reduced complications. We present early results of our patients undergoing this technique. Five patients were selected for open midline repairs; three with chronic infections, one with a prior midline skin graft, and one who desired a primary, tension-free repair. These three males and two females had a mean age of 50.8 ± 21.1 years and body mass index of 30.9 ± 6.2. The mean number of previous abdominal operations was 7 ± 3.4 and previous attempted hernia repairs were 4 ± 2.7. All patients had a midline laparotomy with lysis of adhesions. An endoscopic component separation was then performed bilaterally. Drains were left in the dissection bed. All patients had the midline closed; four received biologic mesh underlays. Mean operative time was 227 minutes ± 49. Mean length of stay (LOS) was 9.2 days ± 3.6. Early median follow-up was 6 months (range 0.25–9). Two patients required postop transfusions, and two patients had mild complications of the midline wound (hematoma, infection). To date, one recurrence was diagnosed by CT scan. Early evaluation of adopting the minimally invasive (MIS) component separation demonstrates minimal complications and good initial outcomes.
