Abstract
Incisional hernia is defined as a defect occurring through the operative scar. It is the only hernia considered to be truly iatrogenic. It occurs due to the failure of the lines of closure of abdominal wall following laparotomy.It is one of the most common conditions requiring major surgery despite advances in surgical techniques and suture material. The incidence of incisional hernia in literature is 2- 11% following all laparotomies and it is a source of morbidity and requires high health care costs.As a result of high recurrence rate in the repair of incisional hernia, various types of repairs have been used both anatomical and prosthetic. But the results have been disappointing with a high incidence of recurrence of about 30-50% after anatomical repair and 1.5-10% following prosthetic mesh repairs.The introduction of prosthetics has revolutionized hernia surgery with the concept of tension free repair. Although a wide variety of surgical procedures have been adopted for the repair of incisional hernia, but the implantation of prosthetic mesh remains the most efficient method of dealing with incisional hernia.The prosthetic mesh can be placed between the subcutaneous tissues of the abdominal wall and the anterior rectus sheath (onlay mesh repair) as well as in the preperitoneal plane created between the rectus muscle and posterior rectus sheath ( retromuscular or sublay mesh repair). The later technique has several advantages, one of being not transmitting the infection from subcutaneous tissues down to the mesh as it lies quite deep in the preperitoneal plane. Moreover the mesh implanted in the preperitoneal space unites and consolidates the anterior abdominal wall. The mesh also adheres to the posterior rectus sheath and renders it inextensible allowing no further herniation.
