Ventral hernias are a familiar surgical problem. Millions of patients are affected each year. They are among the most frequently performed surgical procedures. The risk for a later recurrence repair is significantly higher after sutured repairs compared with mesh repairs.1 In incidence it is second only to inguinal hernias, accounting for 25–35 % of all hernias. Ventral hernias include incisional and primary defects in the abdominal fascia, which can cause umbilical, epigastric, or spigelian hernias. In adults, incisional hernias account for 80% or more of ventral hernias that surgeons repair. The prevalence of incisional hernias after Laparotomy is 2% to 11% and increases substantially when certain risk factors for postoperative incisional hernia, such as a wound infection or obesity, are present. Many patient–related risk factors have been implicated in the development of incisional hernias, including obesity, smoking, aneurismal disease, chronic obstructive pulmonary disease, male gender, malnourishment, corticosteroid dependency, renal failure, malignancy, and prostatism. Obesity often has been cited as a risk factor, with an incisional hernia rate of 15% to 20%. Incidence of Incisional hernias was more in females with male to female ratio of 1:2. Previous surgery or trauma was the single most important cause for ventral (Incisional) hernias. There is an association between an increased complication rate following ventral hernia repair and specific factors , including concomitant bowel surgery, ASAclass, age ,gender and method of hernia repair.2 Other etiological factors were multiparity, obesity, anemia, COPD, BPH, diabetes mellitus alcoholism and smoking. Post operative wound infection was important cause for development of Incisional hernias.
