  Laparoscopic ventral hernia repair is becoming a popular technique with good results and fast postoperative recovery. The mesh is placed directly under the peritoneum and anchored with transabdominal sutures and tacks. However, the ideal size of the mesh covering the hernia orifice is know, nor the ideal type or amount of tacks has to be described.
