INLAY VERSUS ONLAY MESH REPAIR IN THE TREATMENT OF INCISIONAL HERNIA

Abstract :

An incisional hernia is a common complication following abdominal surgery. It is known since the time of laparotomy. An incisional hernia is a true iatrogenic hernia. An incisional hernia occurs in 10-20 % 1of the patients following abdominal surgery. Many factors have been associated with incision hernia like age, sex, obesity, postoperative complications, type of surgery2. The most important factor is wound infection3. All these present a challenging problem to the surgeon. A thorough understanding of the anatomy of the anterior abdominal wall and its biodynamics is important for a successful repair of incisional hernia. An incisional hernia is a complication of laparotomy. It is due to the failure of fascia to heal following a laparotomy. It is more common following midline laparotomy. There are several causes described in the literature for incisional hernia formation. If left untreated, they tend to attain a large size and cause discomfort to the patient or may lead to strangulation of contents. Furthermore, an incisional hernia can incarcerate, obstruct, perforate, or can lead to skin necrosis, all of which increase the risk to patients' life.
