These hernias present as a bulge or protrusion at or near the area of the prior incision scar. Virtually any prior abdominal operation can subsequently develop an<unk>  Hernia at the scar area, including those from large abdominal procedures (intestinal surgery, vascular surgery), to small incisions (Appendectomy, or Laparoscopy). These hernias can occur at any incision, but tend to occur more commonly along a straight line from the breastbone straight down to the pubis, and are more complex in these regions.
