Laparoscopic Repair of Lumber Incisional Hernia
1 year ago
Lumbar incisional hernias are often diffuse with fascial defects that are usually hard to appreciate. Computed tomography scan is the diagnostic modality of choice and allows differentiating them from abdominal wall musculature denervation atrophy complicating flank incisions. Repairing these hernias is difficult due to the surrounding structures. Principles of laparoscopic repair include lateral decubitus positioning with table flexed, adhesiolysis, and reduction of hernia contents, securing ePTFE mesh with spiral tacks and transfascial sutures to an intercostal space superiorly, iliac crest periosteum inferiorly, and rectus muscle anteriorly. Posteriorly, the mesh is secured to psoas major fascia with intracorporeal sutures to avoid nerve injury. Lumbar incisional hernia must be differentiated from muscle atrophy with no fascial defect. The laparoscopic approach provides an attractive option for this often challenging problem.
