An incisional hernia is a defect of the fascia of the abdominal wall following any incision, most commonly surgical incision. [1] It is a type of ventral hernia which is any hernia on the ventral abdominal wall. Ventral hernias may include primary (umbilical, epigastric, spigelian, or lumbar hernias not related to prior incisions) or incisional (following surgery including prior primary ventral hernia repair and trauma) subtypes. .
Traditional "open" repair of incisional hernias can be quite difficult and complicated. The weakened tissue of the abdominal wall is re-incised and a repair is reinforced using a prosthetic mesh. Complications, particularly infection of the incision, frequently occur because of the large size of the incision required to perform this surgery. A mesh infection after this type of hernia repair most frequently requires a complete removal of the mesh and ultimately results in surgical failure. In addition, large incisions required for open repair are commonly associated with significant postoperative pain. Reported recurrence rates after open repair are up to 20% and influenced my mesh size and fixation type.
Laparoscopic incisional hernia repair is a new method of surgery for this condition. The operation is performed using surgical microscopes and specialized instruments. The surgical mesh is placed into the abdomen underneath the abdominal muscles through small incisions to the side of the hernia. In this manner, the weakened tissue of the original hernia is never re-incised to perform the repair, and one can minimize the potential for wound complications such as infections. In addition, performance of the operation through smaller incisions can make the operation less painful and speed recovery. Laparoscopic repair has been demonstrated to be safe and a more resilient repair than open incisional hernia repair..
