Grade B	The suture material for defect closure in IPOM-Plus should be nonabsorbable.
Grade C	Reconstruction of the linea alba (or any defect closure) in laparoscopic ventral or incisional hernia repair combined with IPOM is recommended for hernias of limited size. Additional components separation facilitates the closure and should be used for larger defects.
Grade D	The anterior transfascial suture technique should involve the hernia sac to obliterate the dead space as much as possible with the aim of preventing seroma formation.
