i o d y n a m i c t i s s u eYour Mastery...The ‘direct’ repair of the ventral hernia is hindered by the high percentage of recurrencesdue to the tension exercised on the fascia of the suture and to the conditions of the tissuetropism.Since the first half of the 900’s the most diverse and inert materialshave been researched for use in the closure of a wound or incision withoutplacing tension on the fascia. Only in the second half of the 900’swas polypropylene used, having been shown to be the most fit for thispurpose. There are also meshes in polypropylene adapted for cominginto contact with the bowel loops, and in polyester coated with absorbablesubstances which facilitate the rehypertonization, some coated inIs it possiblea more enlargedindication?silicone, others in PTFE.The problem with this type of prosthesis is the fact that, although inert,it is a foreign body and these can bring complications such as infection,fistulization and erosion of the skin.There are some predisposing conditions to infection which put the successfuloutcome of the implantation at risk.In order to prevent this, it is imperative to be able to trust in a materialwhich gives us the same guarantee as asynthetic prosthesis (resistance to tension, malleability,biocompatibility, allergy resistance),but doesn’t behave as foreign body. Biologicalprostheses is a category which incorporates allof these characteristics, but at the same timeguarantees better protection against infection.The site of the positioning of the organic prosthesisis similar to that of a synthetic mesh,which is fixed around the circumference of awound or incision with re-absorbable stitchesso as to keep it in position. The biologicalprosthesis offers the guarantee that once implanted,it becomes a structure recognized bythe organism. It becomes revascularized andreinforces the deficit in the fibrotic structure.The application of this material is thereforeused electively in all cases where there is potentialcontamination of the wound (the presenceof a colostomy, tearing of the intestine, ahistory of infection of the site)Should the producers of the product renderit more accessible in terms of cost, it wouldbe available for more widespread use also inpatients at risk from potential infection due tocomorbidity (immunodeficiency, advanced age,nutritional state, diabetes, obesity, corticosteroidtherapy etc.)
