Incisional hernioplasty using PDC grafts was found to be a safe and efficient approach to difficult cases complicated by potential contamination [82]. A recent CFTRinh-172 price literature review by Coccolini et al. covered the use of biological meshes for abdominal reconstruction in emergency and elective setting in transplanted patients, and reported a complication rate of 9.4% [85]. By incorporating biological mesh, surgeons hope to provide a collagen-based extracellular matrix scaffold by which host fibroblasts can Selleck SC79 induce angiogenesis and deposit new collagen. The non-synthetic material of biological mesh makes it less

susceptible to infection, and several biological grafts are available in the current market. Their classification is based on the species of origin (allogenic or xenogenic), the type of collagen matrix utilized (dermis, pericardium, or intestinal submucosa), the decellularization process, the presence or absence of cross-linkage, temperature-related storage requirements, and the use of rehydration [86]. On the basis of either the presence or not of the cross-linking,

biological prosthesis are divided into two subgroups: the partially remodeling (cross-linked) buy SBI-0206965 and the completely remodeling ones (not cross-linked). Thanks to the presence of additional linkages the partially remodeling ones resist better and for a longer period to mechanical stress [66]. Coccolini et al. recently published the results of

the first 193 patients of the Italian Register of Biological Prosthesis (IRBP) [87]. This prospective multi-centre study, suggests the usefulness, versatility and ease of using biological prosthesis in many different situations, including clean or contaminated surgical fields. Despite the lack of a cohesive body of evidence, published studies on biological mesh suggest 17-DMAG (Alvespimycin) HCl that cross-linked mesh prosthetics have the lowest failure rate in potentially contaminated and outright infected fields. This trend should be investigated further by means of large, prospective, randomized studies [89]. Recently a critical review of biologic mesh use in ventral hernia repairs under contaminated field was published. All literature reviews found in medline database supported biologic mesh use, especially in the setting of contaminated fields, but the primary literature included in these reviews consisted entirely of case series and case reports with low levels of evidence [90]. To better guide surgeons, prospective, randomized trials should be undertaken to evaluate the short- and long-term outcomes associated with biological meshes under the various surgical wound classifications [91].
