Level 3	Reconstruction of the linea alba in laparoscopic incisional hernia repair improves the functionality of the abdominal wall.
	Reconstruction of the midline (even using open procedure) and laparoscopic reinforcement through IPOM decrease the rate of wound complications.
	Laparoscopically assisted transfascial repair of the midline defects often is feasible under “physiologic tension.”
	Although not “tension free,” the augmentation repair causes less pain in the early postoperative period than bridging repair.
	Augmentation repair (due to combined defect closure and extended mesh overlap) is a stronger repair than bridging repair if technically feasible. The usual overlap of 5 cm can be extended to 8 cm, for example, without an increase of technical difficulty.
	The IPOM-Plus technique reduces the recurrence rate compared with classical IPOM.
Level 4	Closing hernia defects in IPOM-Plus repair minimizes seroma incidence and prevents bulging, thus reducing the patient’s discomfort.
	The augmentation repair decreases the recurrence rate and the incidence of chronic pain.
	Reconstruction of the linea alba without mesh reinforcement leads to high recurrence rates.
