Level 2b	Regarding short-term results (up to 24 months), open ventral hernia repair can safely be performed with biosynthetic absorbable mesh reinforcement
	Despite contaminated operating field, implantation of a biosynthetic mesh may be safe; however, the long-term durability seems less favorable than previously reported
Level 3	Biological mesh and biosynthetic meshes have similar recurrence rates as synthetic meshes in contaminated ventral hernia repairs and may not be superior as previously thought
Level 4	There is no evidence supporting the use of biologic or biosynthetic meshes in laparoscopic ventral hernia repair
