Histologic considerations about a rare case of recurrent incisional hernia on McBurney incision

AIM: Incisional hernias are often related to longitudinal or transverse laparotomy with an incidence that rises from to 2 to 23 %. The oblique incision often used to surgically treat acute appendicitis has little probability to develop incisional hernia with an estimated incidence less than 2%. Some series report 0.1 - 0.9% of it. Anatomic, physiologic and histologic factors have been implicated in herniation development, such as intra-abdominal pressure or alteration on tissue components; many different risk factors can be taken into account to justify this rare condition such as female gender, diabetes, peritonitis, abscess or appendiceal phlegmon as the cause of the first operation, wound infection, seroma, use of cutgut to suture aponeurosis, interrupted suture to the aponeurotic layer. MATERIAL OF STUDY: We present the rare case of young man who underwent surgical operation of acute appendicitis. Mc Burney incision was performed. Successively he underwent re-operation for incisional hernia developed upon McBurney incision and then "recurrence" of the same one. DISCUSSION AND CONCLUSION: Histological analysis of scar tissue was done. Alteration on histological pattern protein expression was discovered.
