The majority of surgeons have the opinion that biologic mesh provides an important and new tool for repair of hernia and defect of the abdominal wall, especially for the contaminated and infected fields. Most of the clinical results showed the short-term outcome of the repair of hernia and defect using biologic mesh is satisfactory, and long--term outcome need to be further investigated. A multicenter, prospective, randomized control trial should be conducted to make sure the relationship of both the types of biologic mesh and the mesh placement to the results of treatment, and the different effect of  biologic mesh for repairing hernia and defect with and without contaminated and infected fields.
