Incidence of incisional hernia in relation to the site of previous abdominal incisions and other related factors


Incisional hernia is a breakdown of the musculo-aponeurotic layer of the surgical scar with a creation of a potential sac that protrudes as a result of increased intra-abdominal pressure through the facial defect. This study was achieved to assess the incidence of incisional hernia in relation to the site of the previous abdominal incision and some other related factors. A prospective study of 75 patients with incisional hernias. A detailed history and clinical examination of every patient was recorded in a special form for data collection, in order to find out the underlying predisposing factor that correlates between the incidence of incisional hernia and the site of the original abdominal wall incision and the rest of the predisposing factor. Incisional hernias were common in age group (41-50) years among female patients but the incidence was more common among the age group of (41-60) in male patients. Fifty four (72%) patients operated on electively. The most common site of previous incision was lower midline. Wound infection was the most frequent risk factor predispose to the development of incisional hernia. Incidence of incisional hernias more in vertical incisions than in oblique or transverse incisions. Re-incising at the same site of the previous incision increases the weakness of the area and predisposes to incisional hernia. Wound infection is blamed for the occurrence of high percentage of cases of incisional hernia. Presentation of patients with incisional hernia is usually within the first 3 years post operatively
