Incisional hernias represent one of the most frequent complications of abdominal surgery. The incidence is probably underestimated. The pathogenesis is complex and not fully understood, implying patient-related factors (i.e., collagen biochemistry, obesity, age) as well as technical factors, including, among others, wound infection, suture material, and types of incisions and closures.
